tenergy batts too hot

Afraid I have been stuck by tynergy too. I bought a pr of emaxx 4200mah pacs and they are and always have been disappointing. New, they never charged to more than 3000 and that was just one of them, the other only 2500-2700. I thought they just needed some c/d cycles so I cycled them a few times and they showed no improvement at all. They won't stan dbehind them either, I tried that route.

Classic signs of bad or marginal cell. You can pull the pac apart and replace those cells and rebuild as a sids by side pac. May get some more time from the for your money, but they are just cheap, low quality cells. They will fair better in something that has a lower amp draw. I won't buy them again.

They act like they are way old and have been sitting. Those that work were probably bought when they were fresh. Long odds though on getting fresh ones!
