Ok thanks. So 120 should be safe enough...and by safe I guess meaning the batteries will be unlikely to put out 120 amps so the board will still go. And the esc, being 120, doesn't want more than 120 going to it anyway I guess.. Or is the esc's 120 rating meaning that's the max that it can put to a motor, and it will typically have a battery attached that has at least that potential?
How does it do away with the need for a shock supressor thing? Couldn't any switch that was stout enough do...since I'm not anticipating needing the breaker action
Batteries can push more current depending on the configuration. I believe, the 120 amps is the continuous and there is a bit of a max amp. Not sure, what you mean by shock suppressor and not any switch can do it. Your pretty much stuck with either an EC5/XT90 loop or a 150/300amp circuit breaker switch.
Unless you do like the production boards and limit max amps to about 40-50 amps, increase voltage and BMS and build your own switch...
