I have some A123 on the way to do some testing on. My hold up with them is there is no way to sure figure out when they need to be charged. Any information would be helpful. Thanks
One sure fire setup: use a CellPro 4 charger -these show voltage and condition of each cell (balance) - and if you can fill your gas tank and go take a p- , in the meantime, the charger will refill your pack and let you know how many amps you just used . Absolutely the safest check out procedure I have seen
there is NFW a loaded meter will tell you how well these cells are charged.
Why?
The voltage output is very flat until th pack runs dry -even under loads
so forget the old technologies -
