That's probably OK, but still a little higher than most people want to go with a lithium battery. Charging to a slightly lower voltage (4.1v or 4.15v) will extend the life of the pack but sacrifice a little range.
You are right. I have found that termination voltage on my iCharger 3010B for LiIo batteries is 4.10 V. So i should to charge pack to 28.7-29 V but not more. Onboard charger is estimated to charge LiPo batteries to 4.25 V per cell.
Is it possible to drop down highest voltage by modification of controller PCB (maybe i should to change one of the resistors or something else)? I can charge it with 3010b, or control the voltage by voltmeter, but it is more comfortable to charge it with onboard charger and did not think about anything.
