Hi Folk's, I wish there were lithium batteries with balancers or self balancing to get rid of all he pesky balancers. One of mine 3.6V opened and then the 130ah CALB cell go up to 4.0V which shut off the charger and you could see number 26 on the battery scanner of course circuit: www.evdl.org/lib/mh but it sure would be a *lot* simpler if there were self balancing lithiums to alleviate all the attracted complexity. I found that a drop of water got on the PC board & sat causing an electrolysis trace disconnect. The boards were conformal coated but still got across a couple points. It also seams that in the winter (<32 degrees) like lead batteries, the internal impedance is higher, more V sag on the highway thus more ah used to go the same distance and the charger taking longer. is there a good LiFePO4 data/info sheet like lead batteries that has *all* the lithium battery characteristics? I wonder how the "big boys" do it, Nissan, Mitsubishi etc, do they have a bunch of pesky cell balancers?
