Solder Battery Lead Direct to Battery?

[bakerb87]

Hey all,

So I was trying to get the battery out of my Hana and very stupidly used a little screwdriver or something, causing the battery to short out and catch on fire. I grabbed it from her quick and blew out the fire to try and save the device and board, which I think I did. The issue I am having now is that the positive terminal of the battery holder is now essentially welded to the shorted battery, leaving the positive battery lead dangling inside my Hana. The battery holder is in there pretty good, so I was thinking of attempting to solder the pos battery lead directly to the positive terminal of a VTC5 18650. I read a bit about this, that I'd have to get some thick grit sand paper or a dremel and roughen up the surface of the positive side of the battery before applying solder so it will stick. I wanted to ask y'all if you think this is a safe, OK idea. And if not, do you have any suggestions for getting the battery cradle out so I can replace the whole thing with a new one? Any help is very much appreciated!

*at least I think that is how I shorted it out, to be honest I don't even remember if I was using a screwdriver or not. AHH! So bummed

Here are some small pics of the positive lead/battery sled

Don't do that...

if anything, solder the lead to a small copper or brass washer and epoxy it in where the original terminal was....and quit digging around in your mod with screwdrivers ...it's all fun and games till someone blows up their Hana

Do some research and find somewhere that you can buy a battery terminal lead and solder that in to the wire and replace the battery.

There is a reason why lugs are tack welded onto batteries used to build battery packs. You don't expose batteries to the high heat generated by a soldering iron. You risk damaging the internal structure of the battery ... and would be right at the same point all over again - another battery vent.

I'm not sure it's the best solution in this case, but it's fine to solder to batteries and you don't need surface prep other than flux. You do need to use good technique though.

Thanks everyone for your feedback. I'm no whiz in electronics or DIY, obviously, but I felt like soldering direct to the battery might not be the way to go. I think I will go the copper washer/epoxy route.

So I got a keystone 18650 cradle. Will that fit into Hana? How do I get the old one out? It's in there pretty good with epoxy
