recommend hookup for 24v battery bank

[lynhnn]

I want to setup 24V battery bank using these Lifepo4 batteries
4 identical - 100A 12v
2 identical - 200A 12v
1 -200 24v
Please recommend me the best (healthiest) to connect them for 24v bank.

Thanks

Set of 4; 2 series, x2
Set of 2; these in series
Single; in parallel with the others using a bus.

Equal length wire from each series pair to a bus.

What’s wrong with 100a @4p 12v
200a@2p 12v
These are series to 4000amp 24v
Then parallel 400a to the single piece 24v 200A?

Ok. I like matching the identical ones in series. Otherwise just monitor them that they stay in balance.

Batteries in series should be identical and at the same SOC in order to stay balanced. Trying to put the 4 100Ah 12V in 4P and the 2 200Ah 12V in 2P and then trying to put those two groups in series is likely to cause issues.

The original suggestion of putting the 4 100Ah 12V in 2S2P, the 2 200Ah 12V in 2S, and then putting those two groups in parallel with the 200Ah 24V will probably work much better.

Side note - battery capacities are measured in amp-hours (Ah), not amps (A).

Will do like suggested. Thank you!
