EXAMPLE:
Mamba Monster ESC can supply 120a continuous
2650kv motor can draw 120a
6500mah 20c battery = 130amps (ok)
6500mah 25c battery = 162.5amps (sweet)
5000mah 15c battery = 75amps (Not good)
4000mah 30c battery = 120amps (borderline
There is a lot of questions/concerns on how each company comes up with their C rating, which leads to question whether the battery can actually perform as advertised. I have some high dollar and some cheap batteries, I can say there is a difference,but not sure it is worth the money.
