Battery Problem

[stephosticks]

I recently received a Kangtech ipow from a friend, and it was all working wonderfully, until one night it just stopped. I have tried a few different things to try to get it working again; prying the pin up, cleaning and checking its compatibility with other carts. After a while I got thinking, maybe the pin isnt connected anymore, so I opened up its guts to find wire that should be on the bottom of the battery pin not soldered into place.

So I am wondering, would it be safe to re solder this back, after stripping the wire a tiny amount, or should I not risk it? Also, if anyone has any experiences with this, what do you think caused it?

Thanks,
Stephan.

i have done this to fix other peoples ego twists, normally the fix is short lived, and it isn't safe unless you insulate the solder point somehow.

 

[jdake3265]

you can try depending on how good you are with soldering

Hello and welcome to the forum. Glad to have you here!

Generally if one has to ask if something is safe concerning electricity they probably shouldn't be doing it.

If you're handy with a soldering iron, go for it!

Solder then use a hot glue gun to insulate. Worth a try...

It was soldered initially... If you are handy with a soldering iron, go for it! If you need some information on soldering on batteries, I suggest looking up some R/C forums and sites, as it is a hobby that deals with building battery packs from individual cells and have a lot of information and tips to help you out!

I have a battery with the same problem. I was wondering if hot glue is a good choice for an insulator? It seems like it would end up melting after heavy use, no?

What have others used to insulate the soldered wire?

Also, the wire doesn't appear to be insulated by the manufacturers to begin with, so is it even necessary to insulate the soldered point as long as it's soldered right onto the heating element and not touching anything else?

Probably not needed, but as it's failed there already the hot glue surround would stop any movement at that point.
There shouldn't be much heat generated by use if the connection is soldered properly

that is how i would do it, hot glue is a wonderful insulator.

there are industrial epoxies that will cost a fortune if hot glue isnt good enough.

Hobby glue guns operate around 250F, the internal components of a mod should NEVER get that hot under normal use.

Not specifically with e-cigs, but I've used electrical tape, brush-on insulation, or heat shrink tubing, depending on access and usage.

As long as the soldered joint isn't in an area or position to come into contact with a metal component, it's not necessary.

I would insulate it no matter what.

Insulating it certainly won't hurt anything, but honestly, at the voltages we operate at, bare metal isn't about to start arcing through air.

yeah it doesn't do that until around 5 or 9 volts, i've skipped electricity on purpose at those voltages, its fun to watch an electricity arc. Even though a jumping electricity spindle wont really wont affect anything unless it jumps to your mouth or toung, lol. it is more to protect the solder joint from any other exposed leads, then you would have a big problem called shorting, your circuit chip in the bat would get fried. Then you can do two things, #1 throw it away since it wont work anymore. Or if you are handy with electronics #2 rip out the circuitry, slap on a switch, slap on a connector, and boom you have an unregulated battery for your tanks, it wont be supper good. I always get broken egos from my B&M and i normally put two together in a parallel circuit so it doubles the mah instead of the voltage like stacking would do. Most egos are from 600 to 1300mah, i think an ego-twist is like 1100mah, so two of those combined is at 2200mah. that is a long lasting battery for your baby tanks like a CE5 and a vivi-nova. just be safe if you do the second option.

I have used hot melt glue as an insulator on several mods I have made myself and never had an issue with it melting.
