mine does this every once in a while. It is something with the balancer. I freaked out one day and immediately unplugged the battery and test each individual cell with my multi meter and none were low nor high. So i plugged it back in and the charger finished it no problem. Also on my trakpower packs i have to start the charge with the balancing OFF then once it is charging plug the balancer connections in and will be fine. Other wise it will say battery connection error. Cant remember the acronym but that is what the error means. Also i found if it glitches out just remove all power to the charger and let it sit a minute then try it again.
