Only 2 of 3 cells work on one battery

[Stolpe]

I'm a noob on this you can say. Only had a Honey Bee CP2 before i bought the T-Rex 450 SE v2.

Anyway when I got it i had to solder the deans contacts to the battery. Because I was so eager to do that I accidently shortcut the lipo once because I had taken of both protecting tubes on the battery at the same time. A real newbee thing...

I also have ordered a charger, a simple Align charger without a display. And when I charge the corrupt battery it seems like it only charge 2 of 3 cells. On the new battery it charges all 3 cells.

When I measure the voltage on the currupt battery it reads only 8,4 volt. Is the battery ruined forever? Or is it possible to repair it in some way? I don't know if the battery was like this from the beginning, dodn't check the battery voltage then.

Probably I have to buy another one and dispose the broken one. Please help...

wow if 8.4 is the output voltage that poor battery is probably toast :bawl

how long was it shorted, just a fraction of a second or a solid second or two? I would be surprised if that only damaged yet thouroghly damaged 1 cell and left the others alone, it is possible that they are all just very low, ie 2.8v/cell. do you have a balancer or a voltmeter to check the voltage of each cell?

It was shorted just a fraction af a second. I will try to charge the lipo battery a few times and se if I can "wake up" the third cell. Otherwise I will have to buy a new one.

I also measured the cells. On one there was 8,45 volt, the other one 4,5 volt and the third one there was 0 volt.

I measured wrong:

On cell 1: 4,5 volt
On cell 2: 4,2 volt
On cell 3: 0,0 volt

Seems like cell 3 is dead.
