Can I use my Zeva BMS for LifePo4 batteries?
I build a Nissan leaf Lithium ion battery pack and use the Zeva BMS and it's worked well for 4.5 years. I purchased 16 Lifepo4 batteries that are 105 amp hours.
I'd like to keep using the Zeva but wondered if I need a Lifepo4 specific BMS? |

Re: Can I use my Zeva BMS for LifePo4 batteries?
From the specs posted above it can be used, but it will need programming for LiFePO4. If you use it without reprogramming it will not offer you protection as the cell parameters are very different between LiFePO4 and Leaf cells.

I'm assuming you hooked up the ZEVA? If so, did you have it reprogramed or is that something you can do in the settings? |
