Testing LiFePO4 Batteries

Well I will be selling them based on their performance. The job bought me this charger to get them going and tested. Took a bit to figure out as the instructions only covered operation and not connection. On airsoft battery chargers they just plug in on the 5 pin cable. On this it charges from the big cables and little cable do the load balance. Very weird way of doing things but no big deal. The instructions should very much have this picture to explain that. Not sure why the indicator on the charger doesn't jive with the meter I have direct to the batteries.
