TP battery not working.

[muddinscx]

I have a thunderpower 3s 1350mah. I used it and went to recharge it and it didn't want to charge on one of my chargers (the charger wasn't regestering it) so I put it on the other charger and that one didn't register it. So I plugged in my other battery (same thunderpower) and the battery chargers registered it and would charge it. So does that mean that the balancing plug isn't working any more or is my battery just done?

It sounds like you discharged the battery too low for a lipo charger to recognized the cells. Are you using some sort of Low Voltage Cutoff on your vehicle?

Try just doing a charge, NOT a balance charge, this will rule out a balance port issue.
If the charger still won't accept it, charge it @ 1A on a 8 cell NiMH setting for a few minutes, then stop the charge and go back to a 3S LiPO balance charge. The NiMH charge will bring the pack voltage up enough for the charger to be happy.

i had the same problem as you,check the wires on the balance plug one of them might have come loose. i just resoldered it on and all was well.

X2, They have the worst balance wires.

Yes it has lipo cut off but I think it got too drained cause it still doesn't reconize it. Maybe my cutoff didn't kick in. The pack ran strong even though it has over 20 charges that I know of (I got it used)

Again, try doing a couple minute charge as a NiMH to get the minimum voltage needed to charge as a LiPO.

This is so true !! I've bought 3 850s this year and I had to resolder or replace the balance plug
