Status: offline 		ok I think I burned up a cell in my pack-actually two packs, don't ask very dumb mistake on my part-I disassembled both battery packs and checked each cell with a digital volt meter-all of them showed voltage-so what gives? most of the cells read around 1.268 volts acouple about 1.275, 2 cells went 1.285 and 2 went 1.258-which ones are bad???? Oh yeah the packs were Intellect 3600 7 cell shotgun style, thanks for the help

If you suspect a bad cell and can check it during a discharge then it will show up as low/no voltage.

Maybe I'm still not clear on the question.

Status: offline 		Thanks for the reply, so if all the cells are reading a voltage-then none of them have been damaged?-and yes I was originally wondering why the charger was reading 6 cells with a 7 cell pack?-

Status: offline 		It was probably a dead battery and it just read it as a 6 cell. When you push start it will recognize it as a 7 cell.

Just because they are all reading voltage desn't nessecarily mean there isn't a weak cell. You would have to measure each cell during the discharge to see for sure. A real good indication when chargeing or using the battery of a weak cell is that it will be quite hotter than the rest of the cells.

The pack just won't have the power it used to.

Status: offline 		thanks to both of you guys for the info, one more thing-do I NEED a cell balancer to charge lipos with my 977-and will it charge A123 racings cells? Thanks again for all the info and help

Status: offline 		It's a good idea to invest in a balancer if you're going to charge LiPos. For one, they are expensive batteries. And two, they are volatile if not charged properly. So for those two reasons I would invest in one. How much is your peace of mind worth? You only have to buy it once, so definitely get one if you're planning on usng LiPos. The 977 doesn't have the circuitry to charge A123s. I'm going to be research on the A123 and charging them on the 989. I'll post when I have results.
