Thanks Jerry for your practical use of parallel pack info using Volt batts! Bummer on the trike - glad you are ok! Did you just use a fixed charge connected to all the packs , no diodes or contactors? It seems more ppl are using Volt packs without any BMS than those that use one. I'm going to be squeezing these Volt packs a little harder than stock though- think the cells might get out of balance more? The pack is going in a big boat and I would like to see 100hp (or ~ 450 amps @ 162V) for a few fun pulls. Boats are like cars except they are always going uphill, no regen or a break in power until the cruise is over. So yes going to use their built in cooling if possible.
