Well, I have seen some very hard use setups involving a123 (a brand name, they are lithium iron, or LiFE) and they do not seem to be too bad about balancing.

Given my experience most batteries only go out of balance for 2 reasons.

1, they are not matched cells, or have very wide mfg tolerances, no QC...

2, over discharge, or pushing the cells hard when they are nearly fully discharge.

As this battery will likely never be fully discharged I should be fine. I do plan to put a balance tap on it, just so I can check and balance charge via a hobby charger if needed.
