At any rate, for your typical 12s setup, the 60v FETs are fine IMO. And the ones you have access to seem quite a bit better than the ones currently in the HV-110 as far as the current, on resistance, and switching time goes. You'd only need one or two layers instead of 3 (of course, more won't hurt ). |
Don't the controllers have a watchdog that knows if a voltage is higher then what they can actually take? I know my Schulze 40.160 will arm at exactly 60 volts and nothing more and they use a MOSFET of the same voltage as the ones my controllers will have. If Patrick can change the MOSFETs for the 100V units and I can use higher voltage, then it will be a plus. I wish they could've done the HV like the MGM with the brainboard in the middle and if you wanted more power just stack the powerboards. Kind of like a hot swap set up.
