For my conversion I'm planning on using LG chem battery 60V 2.6KWh battery packs. I'm plan is to connect them 6s2p and I was wondering what kind of BMS I would need for this setup. The packs are constructed of cells in 12s. So would I need 2 BMSs to monitor each set of (technically) 96s cell blocks?

The problem you'll run into, is if you put 2 modules in parallel, you still need a BMS for both groups. You can't just run balance leads to each, because when you charge or discharge, the groups will shuttle current through those leads to the lower cells or cells with higher IR.

So you'd need two 96s BMS.
You could use:
  • 2 Orion 96s BMS
  • 16 ZEVA 12s boards + Zeva Master
  • One Elithion master + 192 cell boards

Thank you!

BTW, I'm looking at that same setup.

Paralleling groups is good, but you need twice as much BMS, unless you can run heavy balance leads between the cells. It's not simple with these modules, and many others.

Yeah it's a necessary for the performance I'm trying to get. I'm using the drive unit out if a P85 so the extra current capability is a must
