Frequently Asked Questions
Q: 2 3s lipo vs 6s lipo, which is better for Arrma Fireteam?
A: I recommend running 2 3s battery packs. If one battery fails, you only need to buy a 3s battery instead of an expensive 6s battery; if you have other 3s cars, then the 3s battery is perfect.
Q: Soft case vs hard case, which is better?
A: The sturdy hard case protects the cells and is more durable. Soft shells are lighter. It depends on how you drive, there is no wrong answer.
