Thank you for the warm welcome. I've seen the posts about the Leaf and Volt batteries but as far as I've been able to find, they don't generally address overvolting and any use case for lower amps. I'm having trouble find spec sheets for the typical controllers found in electric carts and their voltage tolerance. Good to hear a little extra voltage doesn't seem to cause too much trouble. With the lower current, i'm guessing it will be even less of an issue.

My batteries are custom made from Panasonic li-ion cells and already have a bluetooth BMS built in that allows me to remotely monitor cell voltage and temperature. I have a few thousand watt hours available for capacity but only 40amp continuous current.
