I cannot find any information regarding using a Thunder 1220 in regards to discharging or storage charging/discharging a battery. I am trying to discharge a Li NMC pack to 3.5V/cell but in discharge mode the charger only reads 0.81A (even though I have it set to 5.0A). I also tried the storage mode and also changing the max current setting but it always goes to 0.81A. It may be discharging but if so, it is going really really slowly. It has been running for two days and I think I have taken maybe 0.1V off each cell. The manual is pretty poor on technical information related to discharging. It also lacks any information at all about what the display is actually showing me. Does anyone out there have any experience with that charger (in discharge mode) and have any information they are willing to share?
Thanks,
