Mine came out of a 2015 Volt, how/why a 2015 volt could be unused is beyond me but he claims to have some special connection. Not sure if I'm a sucker but so far the batteries work well. I didn't know anything about BMS so he installed them for $200 per battery (too much?). Maybe next time I'll try to do it on my own but I was focused on getting a working cart sooner.

Question... how would I know what my BMS is set to, or even if it is operating? I could call him, but I should know the right questions to ask.

- What benefits, if any, do I lose in bypassing the OBC? I'm sure there are a lot of threads about it, but let me know if there's a specific thread you think would be particularly helpful.

- I also asked in a seperate reply, but if you have a charger you recommend that would save me some time as well.

Thanks again. Working through this is unexpectedly fun.
That is him and he is smart as you know, battery operated VW, Tesla Engineer, Trainer, etc. But he is still a little old school when it comes to today's technology such as BMS's and Wifi/Bluetooth benefits. That BMS is mainly analog and has no wifi/bluetooth capability. When he and I discussed it, he said you should never have to read it or review it as it works on its own. I can not subscribe to that and he is the one who sets it up so you have no way to adjust anything.

Bypassing the OBC changed nothing else on your operating system of the cart as it is only there for the Powerdrive Charger. It controls it. That is why we are all recommending you by a smart charger and use it instead of the Powerdrive.

MCJEFE had an Amazon link in one of his threads, but those chargers will operate from 58.2 to 58.4 volts. Your Volt pack cannot take that much charge so you need one that turns off at ~50vdc or a CAN enabled charger and a BMS that will shut it off based on pack or cell voltage. The battery module from your pack supplier will also trip off one of those Amazon chargers. He also cells Lithium charges for the Volts but I think they were expensive.

PingEye3 does a lot of conversions, but they are mainly Leafs. He may or may not know of another way of doing it or can help . Sergio is an electronics expert and may also be able to advise you another way.

Good Luck with your goals.

Nole,

Would one of these work for him? Its for a 12S / 50.4v and the same manufacturer as those others...

Yes, that one would work perfectly for him.... 50.04 (4.17v/c) is his threshold and 50.4 (4.2v/c) max just as Leafs are 58.38 and 58.8 respectively.
