Default Dead Orion 4800 LiPo

Came to race this evening, put my LiPo onto charge and it wouldn't register it.

Its an early Orion 4800 LiPo, I got it secondhand towards the end of 2006 and I think its passed the 700 cycle mark. Its not been balanced before, but its never been near the 6v threshold.

The pack isn't swelled at all, and it was perfect the last time I used it (it even won the A-main at my track), it was stored in the car (but not plugged in) until I came to charge it tonight, but for whatever reason its reading 0.0v across the pack - I haven't got a multimeter to check over each terminal and balance port.

Could it have an internal short or something? How safe is it to open it up and look for a broken connection? And does anyone have pics from inside the pack?

i know it might sound stupid but check all your wires on the charger and your bullet connectors.

Yep, first thing I tried. Also put the pack on a different charger and it didn't read it either, so its definitely the pack.

I had a simular thing happen to a pack I have. A fellow racer told me to charge it in regular (NiMh) mode for 5 minutes to get voltage in it and then try it again in Lipo mode. Figuring I had noting to loose I tried it and it worked and the pack ran very strong for me that night.

i would never reccomend that. i dont think there has been a single case of an orion combusting, but DO NOT CHARGE IT AS ANYTHING OTHER THAN LI-PO
the best thing for you to do is test the battery with a voltmeter, if it is below 6.0v dispose of the pack properly.

If you have nothing to lose why not?? i would put it in a lipo sack or two and a screen between it and the charger and charge to outside on nimh

I have seen many times the connectors in the pack come loose and need to be resoldered

Sounds like you shorted it out and blew the internal fuse.

I had a similar problem with my ice charger and a lipo pack, It kept stating short circuit, which i found out meant voltage was too low, I plugged it into my speedo and ran the car on the table for about 30 secs on and off the throttle, hooked it back up to the charger and away it charged.

Maybe it is just sometimes time to retire? Or do you want it to go 7000?
