The better the circuit the lower the spikes and the better the chances, but braking battery regen can still be an issue. If the battery is full and will not accept the regen charge, the voltage can go really high, really fast. Just like motor flyback current that needs a diode or a rectification circuit like our G11, if you do not give the current somewhere to go then voltage spikes can be off the map.
We will know shortly. I am pretty excited about this market and with everything else finishing up we have time now to look at some new challenges.
IF you really need 6s or more and this will not handle it, we will build one that does. That is why we are here learning.

I guess that confirms regen on braking.
