The Arrma Kraton 6s uses The BLX185 150A waterproof ESC.
The lipo needs to be able to produce at least 25% more power than the ESC can draw. This means we need a lipo that can produce at least 190 amps.
ZOP POWER 22.2V 4500mAh 65C 6S Lipo Battery With XT60 Plug
So if we multiply the Battery’s C rating by its capacity 4.5A x 65C = 292.5A
These ZOP power lipos are a bargain and will give more than enough power for the Arrma Kraton 6s https://www.banggood.com/custlink/mDDhdnVN0g
