Limited Amps on Input

[SpEEdyBL]

Putting the packs in a series will make the motor want to draw more amps due to the higher voltage, but if the packs will only allow 60 amps, they will only provide 60 amps. However, putting the packs in parallel will allow 120 amps (60 from each pack) but the voltage will stay the same and the motor will not ask for any more than it did with just one pack.

My guess is that it's not a good Idea to continuously draw max amps from the pack.
