So yesterday my cnhl battery I bought on the black Friday sale finally arrived. On arrival I checked their internal resistance pretty much immediately and it looked pretty good, 1-3 milli ohms per cell. So I charged them and everything looked fine (cells perfectly balanced) and went for a small bash. When I got home I checked the battery again and realized one of the cells wasn't discharged as much as the others (like 0.1 volt more then the rest). So I checked the internal resistance once again and to my surprise, one of the cells (not the one with more volts) has a internal resistance reading of 33. Did some more measuring and it was all over the place, every other measurement one of the cells had a high internal resistance. Put the pack back in storage charge in the hopes that it would help, but it's still the same. Tried both channels of the charger (skyrc ultimate D260), with balance board or directly into the charger and the readings always were all over the place. Never had this issue before, tried another pack and the readings for that pack are not consistent either (yet not as bad as with the cnhl one..).
So what do you guys think about this? Faulty pack or faulty charger?
Already contacted cnhl about the issue, but I don't expect an answer till Monday, so I thought I'd ask you guys for help..
Thanks!
