Hi battery experts. Some of you may have a N30 and be familiar with it. The battery pack is not made to come apart and has a built in charger. It contains 11 sub c cells in series. It runs from a 18 volt 600 ma universal power supply.
I am having a problem with the ending voltage after charging. It is only charging to around 14 volts right after charging and then drops to between 13-14. This would be perfect for 10 sub c in series but not 11. I should see a voltage of over 15 right after charging and it should settle to around 14.7-14.9, which would be around 1.35 per cell. The battery did have those ranges for the first month but now it is as described above.
I want to use a slow 0.1C charge to balance the pack. Can I use a hobby charger hooked up to the positive and negative ports on the back of the battery without damaging the pack or internal charger? Is there any way to know if a cell has gone bad or if it is only out of balance?
