How do you figure out how many amps your lipo battery needs to satisfy the esc/motor combo? Last year when I had my ProBoat Shockwave 26 Brushless out I noticed that after I drained a battery at pretty much full throttle the whole time the battery was quite warm. That boat has a 30 amp ESC (capable of 2S) and a 2900kv motor and I was running a Sky Lipo 2S 4000mAh 40/80C battery. And Horizon sent me the new Shockwave 26 V3 Brushless (because of a flaw with the first one) and it has a 45 amp ESC (capable of 3S) and a 1500kv motor. And I plan on running 3S, just need to know which rating to go with.
