We should also talk to EL-Camino Tom about what he is using on his Lithium pack.

The last time I talked to him about his Lithiums, he said he had
"..... a BMS which only
monitors all cells, does not balance them. Many feel that the balancers
are wasteful and can even unbalance the packs more. If you are willing
to treat them well, LiFePO4 batteries will return the favor. Keep ALL
cells over 2.7V at ALL times, and you will get along if you have a proper
charger."

We can check what he is using for BMS. As a custom electronics engineer, he knows a few things about it.
