strange bl controller

well i knew the first line! lol

thanks alot for the help! that really explained it very well.

so you couldnt really use much more than a 4ah 20c pack with that controller correct?

so if its a 12s 4ah 20c pack it would be just the same as a 3s 4ah 20c pack? as far as how much amps it puts out?

Correct, it does not matter how many cells in the pack, the C rating will determine how many amps the pack can output. Now the motor and gearing will determine how many amps the system can pull, not the batteries capability to provide those amps. That is why batteries usually puff, from being over discharged. Say you have a system that pulls 80 amps and you try to run it with that 3000mah 20c lipo. The lipo can only keep up with 60 amp draw and the system pulls it to 80amps. That would be ok for a short time (a second or two) as most lipos have a short "peak" rating that lets them handle short current spikes. However if that 80 amps draw was there most of the time the battery would most likely puff. I generally try to have my lipo capable of producing about 20% more than I need. If I figure my system wil pull 80amps, then I would want a 100amp lipo, 5000mah 20c for example. Always good to have a little cushion!
