Hi all...…...charging my Prius modules with a hobbyking Quatttro charger. 3 cycles. discharge 1 amp to 6 volts, charge at 2 amps. 1st cycle seeing some higher voltages near the end of the cycle like 8.7 on the charger, 8.5 on the module. For any of you that have been there, is this reasonable???? getting a little nervous.
