Lipo loss caused by spark

G'day.
I just bought a new 1600MaH lipo. It came, as many do, with that weak little plug. I pulled it off to solder on a deans plug. Unfortunately, the leads touched for a split second. Now my Swallow charger won't even recognise the battery is there. Is it lost, or can it be saved?
I have also had a problem with another battery and recognition after I soldered a deans plug on and wondered if the heat from the soldering iron might cause a problem. What do you think?

Leads should be done one at a time. Never have two ,striped battery leads at the same time. When changing connector types ,cut and strip one slip on a piece of heat shrnik , solder to new connector slide heat shrink into position shrink ,now repeat.Never cut both leads at the same time either.

Do you get any voltage measurement at all?

Thanks for the advice guys. I will never make the mistake of doing both leads at once again. I guess theres no hope of replacing the burnt out tAB.
Oh well. This hobby is just like boating. Throwing money into a bottomless hole in the sky

The best two times of owning a boat is the day you buy it and the day you sell it.

Most likely the tabs are OK, but check it there is a small PCB on the battery pack. If there is then it may be a crossover between cell one add cell 2 (cell one being the one with (+) wire attached.)


During a short this crossover acts as a FUSE all you need to do is jump it with some wire and solder. (solder alone may not work)

Best Wishes,

Thanks Dan. Excuse my ignorance. What does PCB stand for? Do you have a photo of what you mean? Cheers mate.
Regards,
Mark
