Lipo safe to charge???
Hi lads,
Could somebody advise me on whether my Lipo's will be safe to charge after a short. Yesterday I was charging my Orion 5500 90c saddle pack on my Core rc charger. When the charge was completed and I was taking them off charge I accidentally touched the positive and negative connectors together whilst they were still connected to the Lipo's which caused an aggressive spark. Upon inspection the connectors had melted into the casing of the Lipo's which meant a lot of tugging to get out and the case is loose around the seal between the two halves of the lipo saddle. As the battery was charged I tried it in my car at the track yesterday and felt just as powerful as ever its just now it needs charging again and I'm a little dubious as to whether its safe with the casing now damaged? Could anybody please shed some light as I don't want to damage my charger, the lipo further or more so me!! Thanks Chris

Should be fine, charge it in a ceramic pot/lipo bag to be on the safe side and keep an eye on it.
Balance it and maybe mark it so you know to keep an eye out for it later on if you have a couple that look the same

Should be OK I've done it a few times!
Just use a sack and personally I would charge at less than 1C to be safe! Just keep an eye on it.

I would strongly recomend you unplug from the Lipo end don't leave wires in the Lipo at all

Just a note of common sense...
there is absolutely no way that anyone (even those that have done this themselves) can say this damaged lipo is safe to charge. You have posted no pictures, so the actual extent the the damage is not clear. The fact you have used the lipo without problems is a good sign, but not definitive. Charge and use this lipo at your own risk.

Thanks for the replies lads and and I will obviously charge with caution now. Would reducing the ampage help at all? And are there any signs I should look out for when charging that suggest all is not well and I should disconnect them
Immediately? Chris
