I've got a golf cart that I am retrofitting with 48V 45Ah Li packs salvaged from a Chevy Volt. I am currently testing the cart with just one of these 12S packs and so far so good. I'm using a programmable charger and a BMS on the pack. I'm charging to 4.1V per cell for a pack voltage of 49.2 when fully charged.

45Ah won't give be enough range so I plan to add 2 more of these packs and run them in parallel. Each will have its own BMS but I'd liek to run just one charger. Can I charge all 3 packs in parallel with a single charger, allowing the BMS on each unit to regulate when it can an cannot charge?

I plan to run the charge and discharge in parallel, but I'm probably going to run each pack on it's own BMS. I'll set both BMS modules the same with an over voltage cutoff set just above the charge voltage I set on the charger. For now I'm charging to 50V, so I'll probably set the BMS to cutoff charging at 50.4V.
