How To: Make a Y Balancer Harness

No - it is not possible to wire a pack as a 2s2p and then try to balance it as a 4s. Since you have paired cells the balancer would not be able to "see" the cells as separate.

if you could reconfigure the pack to 2p 2s vs 2s 2p you'd have more options....

Gibberish...

Anyways, it is not possible to wire a pack as a 2s2p and then try to balance it as a 4s. Since you have paired cells the balancer would not be able to "see" the cells as separate.

If you left the cells configured as 2 2s packs you could make an adapter to charge them as a 4s, but you mentioned lack of room to do that.

I would just wire them as a 2s2p pack and use a 2s balancer harness. As long as the cells are similar in age and usage they should be fine. The paralleled pairs of cells will naturally equalize voltage. If the cells were different in age by alot you may have issues with one cell in the paralleled pairs taking voltage faster during the charge, that would be the only issue that I can think of.
