Shorted a Lipo...

[BennyMac]

Was replacing the deans connector off a new battery with XT90s and accidentally crossed the wires with pliers (doh!). It sparked and the wires right where I crossed it were a little hot, battery is fine. Do you think I've damaged the battery? Safe to use?

Can you check it on your charger? Mine checks each cell when you plug it in and will tell you if you have bed cells in the battery.

Yeah I have a Swallow EQ charger and it does a battery check. I've put it on and it didn't come up with anything. I assume it is all good.

Probably OK if it was just a momentary short. I bet it was exciting though!

I did the exact same thing a few months ago - nearly blew my pliers up, gave a nice big spark, but the battery was fine. Just make sure it doesn't puff up on the first few runs afterwards but I wouldn't worry at all.

Cool cool, thanks for the replies. It was exciting MrFurious40k, big arc of the pliers - my son was watching and he was like "is that normal Dad?" ! I was like "Ahhh... well not really" trying to act cool lol.

I can also confirm I made the identical mistake, with no harm done to the 3S battery. After two years it still runs fine.

Both a scary and exciting experience
