Hi,
I've been lurking around for awhile, but decided to sign up to get some advice. My UPS is in need of a battery replacement and currently uses two 12v SLA 9aH batteries in series to give 24V. I'm trying to decide what is the best approach to replace these with a DIY lithium solution (wetting my feat before jumping into a powerwall).
I will determine how many cells can be put in parallel based on what will fit inside my UPS . Each solution will include an appropriate BMS (suggestions welcome on this, was thinking of a Daly BMS).
So far these are the ideas I have come up with:
Thanks!
Mike

So far these are the ideas I have come up with:
- LiFePo4 in a 8s#p setup using 36700 cells
- Lithium in a 7s#p setup using 18650 cells
- Lithium in a 6s#p setup using 18650 cells
Thanks!
