To expand on Jim's answer, LiFePO4 packs need to charged with a 
cell-balancing charger designed for LiFePO4's.  My battery plugs into 
the charger with a multi-conductor plug separate from the power leads 
that go to the radio.  The charger tells me the voltage on each cell as 
charging takes place.  For longest storage life, they like to be put 
away at about 85% or so charge.  My charger has a" LiFePO4 Storage" 
charge setting.

My charger is from Revolectrix, I can give you the model # if you want, 
we're moving and I need to go find it.
