    I'm doing 1 module at a time. Set charger to charge at 5 amps, 6500mah cap, 2amp discharge, 6.4V discharge. 6.4v because its either that or about 5.6v or so.

    The voltage got up to 8.4v and the charger says it's putting in 8.95v. I have a multi meter on it and checked it when it paused to check. I got at least 195mah on the discharge which I interrupted on accident, then 1223mah on the charge that I stopped because of 8.4 voltage.

    This is supposed to be one of the good modules. I checked all of them after getting it taken apart. The highs were around 8.14 and the lows around 7.99.

    I'm running 2 different chargers. Maybe this one is bad? Dr Prius says I've had up to 8.8v module 8.4 seems to be green but 8.8 will turn the graph yellow. That is when driving.

    Anyone got any ideas?

    5 amps? Did you mean mili amps? From what I've read, lower amps is better.
    But what do I know? :whistle:
