Yeah, that PL8, along with most of the rest of the Cellpro line, along with perhaps many other name brand LiPo chargers may go into their "Safety" mode of charging a LiPo battery that is way out of balance.

My PL8 chargers go to a 500 milliampere charge rate under this condition, even when it's programmed for a 30 Amp charge rate for my A123's. (That is a 12S2P pack being charged as a 6S4P pack.)
