Choosing between the Kraton 6S EXB and Typhon 6S TLR often comes down to one overlooked factor: how each platform handles battery compatibility and heat management. Both rigs run 6S power, but the similarities end there. The Kraton’s monster truck chassis and the Typhon’s low-slung buggy frame create completely different thermal environments, battery fitment constraints, and real-world runtime expectations.
If you’ve been running ARRMA 6S cars for any length of time, you already know that stuffing a pack into the tray is only half the battle. The real question is whether that pack will survive sustained full-throttle runs, how hot your ESC gets after 15 minutes of aggressive driving, and which chassis actually lets you swap batteries without a wrestling match. We’ve been testing both platforms through 2025 and into 2026, and the differences are more significant than the spec sheets suggest.
This breakdown covers everything from physical battery dimensions and connector choices to cooling system effectiveness and practical runtime in different conditions. You’ll walk away knowing exactly which platform suits your driving style, which batteries actually fit without modification, and how to keep both rigs running cool when you’re pushing them hard.
Kraton 6S EXB Battery System: Space, Airflow, and Flexibility
The Kraton 6S EXB accepts batteries up to 155mm in length and 47mm in width, making it one of the most accommodating 6S platforms in the ARRMA lineup. This generous tray size means you can run everything from compact 5000mAh shorty packs to beefy 6500mAh full-size batteries without modification.
ARRMA designed the EXB chassis with a composite battery tray that sits relatively high in the frame. The tray uses a simple strap retention system with two hook-and-loop straps crossing over the pack. It’s not the most secure setup for extreme air, but it works reliably for most bashing scenarios. The real advantage here is accessibility. Pop the body, undo two straps, and you’re swapping packs in under 30 seconds.
The Kraton’s tall monster truck stance creates natural airflow channels around the battery compartment. Air enters through the front bumper area, flows under the chassis, and exits around the motor mount. This passive cooling keeps battery temperatures noticeably lower than enclosed buggy designs. During summer testing at 32°C ambient, our 6S 5000mAh packs rarely exceeded 45°C after a full discharge run.
Connector-wise, the EXB ships with IC5 connectors as standard. These are ARRMA’s current generation plugs, rated for continuous 150A draw. They’re robust enough for 6S power, though some bashers prefer to swap to EC5 or XT90 connectors for better third-party battery compatibility. If you’re buying new packs specifically for the Kraton, stick with IC5 to avoid adapter losses.
One thing worth mentioning: the Kraton’s battery tray sits above the center differential. This positioning means heat from the diff housing can radiate upward toward your pack during extended runs. It’s not a major issue with proper diff maintenance, but if you’re running thick diff oil and pushing hard, that heat transfers. We covered diff maintenance in detail in our differential bulletproofing guide, and the thermal considerations apply here too.
The EXB designation means this chassis comes without electronics, so you’re choosing your own ESC and motor. Most builders pair it with the Spektrum Firma 150A ESC and 2050Kv motor combo. That ESC includes a built-in cooling fan, which helps manage system temperatures when you’re running aggressive gearing.

Typhon 6S TLR Battery System: Precision Fitment and Lower Mass
The Typhon 6S TLR has a maximum battery length of 139mm with a width limit of 47mm, making it noticeably more restrictive than the Kraton. This tighter fitment exists because the TLR chassis prioritizes low center of gravity over battery flexibility.
TLR stands for Team Losi Racing, and this collaboration brought race-oriented design principles to the Typhon platform. The battery tray sits as low as physically possible in the chassis, tucked between the side rails. This placement drops the center of mass by roughly 8mm compared to the standard Typhon 6S, which translates to better cornering stability and reduced rollover tendency at speed.
The tradeoff is obvious: you’re limited to shorter battery packs. Most 6500mAh 6S batteries exceed the 139mm length limit, so you’re typically running 5000-5500mAh packs. That’s still plenty for 15-20 minute sessions, but it does mean more frequent swaps if you’re doing extended bashing days.
Thermal management on the Typhon TLR is more challenging than the Kraton. The enclosed buggy body traps heat around the electronics bay, and the low battery position means less natural airflow. During identical ambient conditions (32°C), our test packs hit 52°C after full discharge, roughly 7°C hotter than the same pack in the Kraton.
The TLR chassis includes better ventilation than the standard Typhon, with additional body cutouts and a vented motor cover. These help, but they don’t fully compensate for the enclosed design. If you’re running the Typhon hard in summer conditions, consider adding a small ESC fan or limiting runs to 10-12 minutes with cool-down periods.
Like the Kraton EXB, the Typhon TLR uses IC5 connectors. The retention system is similar too, using strap-based hold-downs. Battery swaps are slightly more involved because you need to remove the body and work within the tighter side rails, but it’s still a sub-minute operation once you’ve done it a few times.
The TLR version comes as a roller, meaning no included electronics. The popular build path is the same Firma 150A and 2050Kv combo, though some racers opt for the higher-revving 1900Kv motor for track use. Your motor choice affects heat generation significantly, with the 1900Kv running hotter under load.

Key Differences That Actually Matter
The spec sheets show both cars running 6S power, but the real-world experience diverges significantly once you start pushing these platforms. Here’s where the differences become obvious.
Battery Tray Dimensions
The Kraton EXB accepts packs up to 155mm long. The Typhon TLR maxes out at 139mm. That 16mm difference eliminates most high-capacity 6500mAh batteries from Typhon compatibility. If you already own larger packs from other builds, the Kraton will use them. The Typhon likely won’t.
Thermal Headroom
Open chassis designs run cooler. The Kraton’s monster truck body sits high above the electronics, allowing heat to dissipate naturally. The Typhon’s enclosed buggy shell traps warm air. Expect 5-10°C higher pack temperatures in the Typhon under identical conditions. This matters more in summer or during sustained high-throttle driving.
Center of Gravity
The Typhon TLR’s low battery position creates a lower center of mass by approximately 8mm. This improves cornering grip and reduces tip-over tendency during aggressive turning. The Kraton’s higher battery placement contributes to its characteristic body roll, which some drivers prefer for the visual drama but others find limiting at speed.
Swap Speed and Accessibility
Both cars use similar strap retention, but the Kraton’s more open tray makes swaps faster. You can almost reach in blindly and secure a pack. The Typhon requires more precision to slot the battery between the rails. It’s not a major difference, but it adds up over a day of bashing.
Connector Ecosystem
Both platforms ship with IC5 connectors, maintaining compatibility across the ARRMA ecosystem. If you’re running multiple ARRMA vehicles, your packs work in either car without adapters. Third-party batteries often use EC5 or XT90 connectors, requiring either resoldering or adapter use.
Weight Distribution Impact
Battery placement affects handling beyond just center of gravity. The Kraton’s higher pack position creates more pendulum effect during jumps, which can help with nose-down rotation for landing. The Typhon’s low pack keeps the car flatter in the air, requiring more throttle management for jump attitude control.

Real-World Performance by Terrain
Numbers only tell part of the story. How these cars actually perform with different battery setups across various surfaces reveals their true character.
Parking Lot and Pavement
The Typhon TLR dominates smooth surfaces. Its low center of gravity and 38mm ground clearance keep it planted through high-speed corners. The low battery position contributes to this stability, allowing full-throttle sweeping turns without the tip-over anxiety you get with taller trucks. A 5000mAh pack delivers 15-18 minutes of aggressive street running before voltage sag becomes noticeable.
The Kraton can run pavement, but it’s not in its element. The 83mm ground clearance and higher mass center make it twitchy at speed. You’ll find yourself backing off the throttle through turns that the Typhon takes flat out. That said, the Kraton’s larger battery capacity option means longer sessions if you’re just doing speed runs and not pushing cornering limits.
Loose Dirt and Gravel
Both platforms handle loose surfaces well, but for different reasons. The Kraton’s weight and larger tires (170mm diameter vs the Typhon’s 145mm) provide better flotation over soft material. The higher battery position actually helps here, as the raised mass prevents the truck from digging in during acceleration.
The Typhon’s lower stance means more debris ingestion. Dust and small rocks find their way into the electronics bay more readily. If you’re running loose surfaces regularly, the Typhon needs more frequent cleaning to prevent motor and ESC contamination. The Kraton’s open design paradoxically stays cleaner because debris passes through rather than accumulating.
Backyard Jumps and Big Air
Here’s where the Kraton earns its reputation. The monster truck suspension travel (front: 95mm, rear: 110mm) absorbs landings that would damage the Typhon. The higher battery position creates rotational mass that helps control jump attitude. Nose too high? Brake tap. Nose too low? Throttle blip. The response is immediate and predictable.
The Typhon TLR can jump, but it requires more skill to land cleanly. The stiffer suspension and lower mass center mean less forgiveness on imperfect landings. Big air isn’t really what this chassis was designed for. It’s a speed machine that happens to have suspension, not a dedicated basher.
Grass and Rough Terrain
Grass running favors the Kraton heavily. The tall tires cut through vegetation, and the high ground clearance prevents hangups on uneven terrain. Battery temperatures stay reasonable because the open chassis allows airflow even when grass is pressed against the underside.
The Typhon struggles in thick grass. The low body acts like a plow, and the enclosed design traps heat when airflow is restricted. Short grass or maintained lawns work fine, but anything over 3-4 inches tall becomes problematic. You’ll see motor temperatures climb quickly.
Battery Selection and Charging Best Practices
Getting the right pack for each platform requires understanding more than just physical dimensions. Discharge rate, cell quality, and charging habits all affect performance and longevity.
Capacity Sweet Spots
For the Kraton EXB, the sweet spot is 5500-6000mAh. These packs fit comfortably, provide 20+ minute runtimes, and don’t add excessive weight. Going to 6500mAh gains maybe 2-3 minutes of runtime but adds noticeable mass that affects handling. Unless you’re doing distance runs without access to spare packs, stick with the mid-range capacities.
The Typhon TLR works best with 5000mAh packs around 135mm length. This leaves a small buffer in the tray for expansion during discharge (yes, LiPo cells expand slightly when warm) and ensures clean fitment. Trying to squeeze in a 138mm pack that technically fits often leads to tight tolerances that make swaps frustrating.
→ 6S LiPo Battery 5000mAh, A 5000mAh 6S pack at 50C or higher discharge rate provides the best balance of runtime and fitment for both platforms, especially the dimension-sensitive Typhon TLR.
Discharge Rate Requirements
Both cars pull significant current under full throttle. The Firma 150A ESC can draw sustained loads exceeding 100A during aggressive acceleration. Your battery’s C rating matters here. A 5000mAh pack needs at least 50C continuous rating to safely deliver 250A burst current. Anything lower risks voltage sag under load and potential cell damage.
Cheap batteries with inflated C ratings are everywhere. Stick with established brands that have been tested by the community. Gens Ace, Spektrum, and CNHL have proven reliable in our testing. The few dollars saved on budget packs isn’t worth the performance loss and safety risk.
Charging Infrastructure
Running 6S platforms requires a capable charger. Single-output chargers rated for 4S max won’t work. You need a unit that handles 6S (22.2V nominal, 25.2V fully charged) with balance charging capability. Charge rates of 1C are safest for longevity, meaning a 5000mAh pack should charge at 5A or less.
Dual-output chargers let you charge two packs simultaneously, cutting your downtime between sessions. If you’re running multiple cars or doing extended bashing days, this capability becomes essential. We’ve found that having four packs in rotation with a dual charger means nearly unlimited runtime.
→ LiPo Balance Charger 6S, A quality balance charger with 6S capability and at least 10A output ensures safe, fast charging that maximizes battery lifespan across both platforms.
Cooling Upgrades and Thermal Management
Both platforms benefit from cooling upgrades, though the Typhon needs them more urgently. Here’s what actually works versus what’s marketing hype.
ESC Fan Upgrades
The Firma 150A ESC includes a small cooling fan, but it’s undersized for sustained high-load operation. Upgrading to a higher-CFM fan or adding a secondary fan on the heatsink drops ESC temperatures by 10-15°C. This is more critical on the Typhon where the enclosed body restricts natural airflow.
For the Kraton, the stock fan is usually adequate unless you’re running in extreme heat or doing continuous full-throttle pulls. The open chassis compensates for the modest fan output.
Motor Heatsinks
Clip-on motor heatsinks add surface area for heat dissipation. They’re inexpensive and genuinely effective, dropping motor can temperatures by 8-12°C in testing. The Typhon benefits more due to its restricted airflow, but even the Kraton sees improvement during summer sessions.
Body Ventilation
The Typhon TLR comes with some ventilation cutouts, but adding more helps significantly. Strategic holes above the motor and ESC create convection paths that pull hot air out. Just be careful not to compromise structural integrity or create water ingress points if you run in wet conditions.
The Kraton’s body sits so high that additional ventilation rarely matters. The gap between body and chassis provides all the airflow you need.
Servo Considerations
Heat affects more than just the motor and ESC. Servos generate significant heat under load, especially the high-torque metal gear units these platforms demand. Both the Kraton and Typhon benefit from quality servos rated for the thermal environment they’ll face.
→ Metal Gear Servo High Torque, A 25kg+ metal gear servo handles the steering loads of 6S power while resisting heat-related failures that plague plastic-geared units.
Who Should Buy Which Platform
After extensive testing through varied conditions, clear use-case patterns emerge. Neither car is universally better. They’re optimized for different driving styles.
Choose the Kraton 6S EXB If:
You prioritize big air and aggressive bashing over precision handling. The Kraton absorbs abuse that would damage the Typhon. Its generous battery tray accepts whatever packs you already own. The open chassis runs cooler with less maintenance. If your typical session involves backyard jumps, rough terrain, and the occasional full-send into the unknown, the Kraton is your platform.
The Kraton also makes sense if you’re building a family fleet. Its forgiving handling and robust construction survive beginner mistakes better than the Typhon’s precision-oriented design. Kids and new drivers adapt to it faster.
Choose the Typhon 6S TLR If:
Speed and handling precision matter more than versatility. The Typhon TLR corners like it’s on rails. Its low center of gravity and race-derived suspension geometry reward skilled driving. If you’re doing parking lot speed runs, track days, or high-speed street circuits, nothing in the ARRMA lineup matches it.
The Typhon also suits drivers who want a project. The TLR chassis responds well to tuning. Shock oil weight, spring preload, camber angles, and toe settings all produce noticeable handling changes. If you enjoy dialing in a setup rather than just sending it, the Typhon rewards that attention.
Battery Inventory Considerations
If you already own multiple 6S packs, measure them before deciding. Packs over 140mm long won’t fit the Typhon TLR without modification. The Kraton accepts nearly everything on the market. This practical consideration often tips the decision for bashers with existing battery collections.
For those buying fresh batteries alongside their new car, this matters less. You can spec packs specifically for your chosen platform. But if you’re like most of us with a drawer full of random packs from previous builds, compatibility becomes a real factor.
Frequently Asked Questions
Can I use the same batteries in both the Kraton 6S EXB and Typhon 6S TLR?
Yes, if your packs are under 139mm long. Both cars use IC5 connectors and accept 6S voltage. However, many 6000mAh+ packs exceed the Typhon’s length limit. Measure your existing batteries before assuming compatibility. Packs between 130-138mm work in both platforms without issues.
Which car runs cooler during extended sessions?
The Kraton 6S EXB runs significantly cooler due to its open monster truck chassis design. Testing shows 5-10°C lower battery and ESC temperatures compared to the Typhon under identical conditions. The Typhon’s enclosed buggy body traps heat, requiring more attention to thermal management during summer driving.
What capacity battery provides the best runtime for the Typhon 6S TLR?
A 5000mAh 6S pack at 135mm length offers the optimal balance. This capacity delivers 15-18 minutes of aggressive driving while fitting comfortably within the 139mm tray limit. Higher capacity packs often exceed dimensional limits, and smaller packs sacrifice runtime without meaningful weight savings.
Do I need to upgrade the cooling system on either platform?
The Typhon TLR benefits more from cooling upgrades due to its enclosed design. Adding a higher-CFM ESC fan and motor heatsink drops temperatures by 10-15°C. The Kraton’s open chassis provides adequate cooling for most conditions, though summer bashing in hot climates still benefits from fan upgrades.
Can I run 4S batteries in these 6S platforms?
Yes, both cars operate on 4S power with reduced performance. Speed drops approximately 33%, and acceleration decreases noticeably. Running 4S is useful for beginners learning control or for situations where full 6S power is excessive. The ESC handles both voltages without adjustment.
What’s the price difference between these platforms in 2026?
The Kraton 6S EXB typically sells for $449-499 USD while the Typhon 6S TLR runs $479-529 USD. The TLR commands a premium due to its race-derived chassis components. Both prices are for roller versions requiring separate electronics, battery, and transmitter purchases.
Which platform handles grass and rough terrain better?
The Kraton 6S EXB handles rough terrain significantly better. Its 83mm ground clearance, 170mm diameter tires, and higher suspension travel allow it to traverse grass, rocks, and uneven surfaces that would high-center the Typhon. The Typhon’s 38mm clearance limits it to maintained surfaces.
Final Verdict
After running both platforms extensively through 2025 and into 2026, the choice between the Kraton 6S EXB and Typhon 6S TLR comes down to one fundamental question: what do you actually want to do with your RC car?
The Kraton 6S EXB wins on versatility, battery flexibility, and thermal management. Its 155mm battery tray accepts nearly any 6S pack on the market. The open chassis design keeps temperatures manageable without aftermarket cooling. The monster truck suspension handles terrain variety that would destroy the Typhon. If you want one car that does everything reasonably well, the Kraton is the answer.
The Typhon 6S TLR wins on speed, handling precision, and outright driving engagement. Its low center of gravity and race-derived suspension create a driving experience the Kraton can’t match on smooth surfaces. Yes, you’re limited to shorter batteries and need to manage heat more carefully. But if you’re chasing lap times or carving parking lot circuits, those tradeoffs are worth it.
For most bashers who run varied terrain and don’t want to think too hard about battery selection, the Kraton 6S EXB is the more practical choice. It’s more forgiving, runs cooler, and accepts whatever packs you throw at it. The Typhon TLR is the specialist tool for drivers who know exactly what they want and are willing to work within its constraints to get it.
Both platforms share the same 6S power potential and IC5 connector ecosystem. Both require similar electronics investments as rollers. The difference is in how they deploy that power and what driving experience they deliver. Choose based on your terrain, your driving style, and your existing battery collection. Either way, you’re getting a capable 6S platform that will provide years of bashing enjoyment with proper maintenance.
