Charging and Balance of 48V Chevy Volt Module

Batteries and Charging - DIY Electric Car Forums - www.diyelectriccar.com
Hello all,

I've ordered a 48V module out of a Chevy Volt pack and I plan to replace the lead acid batteries in my golf cart with it. For the time being I'm going to run a single 48V module but once I get all the details of BMS and charging worked out I'll add another in parallel to increase my range.

I'm planning to use a BMS to control charging and balancing only and I'll try to rig a warning light of some sort to warm me of over temp conditions while drawing load directly from the pack. I currently have 2 main questions.

1. The Volt module is a 12S configuration which I'll probably charge to a max of 48V. It seems most chargers are design for a slightly higher charge voltage. What is a decent adjustable voltage charger that won't break the bank? I don't need high amp charging as I'll generally charge over night. 5A to 10A will probably be fine.

2. I can find plenty of 12S BMS units, however many seem to be sourced from over seas and I am unsure of their quality. Who makes a reliable BMS that will work with the lower voltage per cell Volt pack? More bells and whistles are always cool but not necessary at this point.

Any advice is greatly appreciated.

Tom
