So I have a 3s turnighy 5000mah battery that was knocked around inside a Spartan after it launched in the air at full speed and tumbled. When I checked the taps the middle cell does not read in my meter and when connected the battery shows as 0 volts however when I check the taps the first and third cell show fine. I'm guessing it's wire connection got knocked off. Can I fix that?
Lipo Salvageable?

That's cool. I'm friends with the owner of the lhs and they had a lipo sitting off to the side I asked what the deal was they said it wasn't registering any voltage, I brought it home and just repaired it now. Free lipo woohoo. I checked the voltage to each individual cell and they all read 3.8v per cell which is perfect I then measured voltage at the discharge/output wires and it measured 0v total I then used thed balance tap and it also read 0v that told me the series circuit was open somewhere after searching the board I found where the problem was. Seems the batt may have been shorted out and blew out a connection point. 30 seconds of soldering and back to new! Took 5-6m total!

SO i opened the top up just like you and can't seem to find anything. I still left one of the protective plastics on but you can see.
The second picture shows where i place the wires of the voltage meter and get 0 volts.
as you can see in the picture i have in order BLACK, YELLOW, BLUE, and RED wires. When i test black & yellow its fine. test yellow and blue its 0 volts, blue and red fine. But then i check BLACK AND RED and it says 0 volts... whats going on here??

The fact your reading 0 at the output cables (red/black) or your traxxas plug, indicates it's a open circuit. If just a cell was dead the output at the cables should read as a 2s instead of a 3s pack. There has to be a very VERY small area that doesn't connect.Comment

But why does it read with black - yellow & blue - red but NOT blue & yellow? Do I have to open it up completely?Comment
