Re: Parallel LiFePO4 Packs

Connecting two 230Ah cells together in parallel (sixteen times) would allow you to treat the 32 cells as one large 16S 48V x 460Ah battery
BMS, load, charger, capacity monitoring would be none-the-wiser.
One concern of that configuration that wouldn't otherwise come up is if one cell in a two-cell pair were to fail.
If the failure is a short, it would bring the other cell with it.

Hi Group,
My Morgan Out Island 41 is ready for new batteries. I’m ready to embrace LiFePO4. When I originally converted to electric I built and glassed in 2 battery boxes to hold 2 banks of 8 (16 batteries) golf cart batteries. I always run with both banks in parallel, but have the ability to run on just 1 and this has worked well. Unfortunately this size battery box doesn’t make efficient use of most individual LiFePO4 cells. I would however be able to use 32 X 230Ah EVE cells in 1 battery box, leaving the other box for some other purpose. My questions: I’d like to be able to run the 2 X 16S strings in parallel. Is this possible with LiFePO4? Is it safe to do this? Any precautions? Would I have 2 separate BMS units? How about capacity monitoring for the 2 banks in parallel? I have a Victron 48V/5KVA Victron Quattro charger inverter.? Thanks in advance for any assistance/suggestions. Regards, Chris Hudson Sent from myPhone |
