RE: Lipo Query - Any one help??
Get a good DVM and compare the cell voltages without the charger attached. It could very well be the charger balancer circuitry is not accurate or has drifted. If the DVM says all the cells are the same, the charger is in error. If the DVM agrees with the charger as far as the delta between cells, then the cells are unbalanced.
The DVM and the charger will not necessarily report the same voltage (it will be close) but what you are interested in is the delta between the cells reported by the DVM. The charger should report the same delta. If not, the charger is out of calibration.
