At the risk of seeming trite, THE best suggestion for users of the site that are looking for more specific information is to really learn how to use the search engines available here. Once I did, finding information on the site as a whole or in those monster threads became fairly simple. I still do resort to asking questions if I don't find what I was looking for in a reasonable amount of time and helped immensely in navigating one of the largest discussion forums on the internet. It really is how I became an "expert" in navigating forums in general and how I maintain the ability to point others in the correct direction.

Eleven years of hanging around this place didn't hurt either.

Maybe you could write a sticky on using the search function.

Seriously, I use the search function quite often, both here and of course, the one and only expert maker in any field........drum roll please...rat a tat tat......Google.

I hear you Mark and I agree. Believe me I use the search feature liberally. But I also know that I'm gonna ask a few questions at some point that have been answered a million times. Either cause I don't have the time for a 15min search and read, or because when I do read I often find multiple view points and want a little more info from the resident experts.

Hi guys,

I have a puffy HobbyZone 1S 12C 150mAh LiPo battery here that reads 4.22V on my voltmeter.
It started to puff up while on the charger a week ago, did not put a load on it afterwards, and only now bothered to measure the voltage.

So here it is, sitting on my desk, very puffed up but not punctured/leaky. Can I save this little guy and if not, how do I dispose of it safely?

Are completely (down to zero volts) discharged cells still chemically volatile somehow? Apart from potentially poisoning yourself with Cobalt or Manganese, are there any risks when completely disassembling such a cell?

Have never seen a reported incident of a discharged lipo burning/smoking/etc, however, there are risks in opening the cells as the electrolyte/solvent is not human friendly.
See the MSDS-

Why do you want to dissemble the cell?

Thanks hoppy!

I would like to salvage the micro sized plug to make a plug adapter. I prefer to disconnect the plug from the cell without exposing the electrolyte/chemicals but it might happen that the seal breaks and I like to know the risks.

Shouldn't be a problem as the wires are usually connected to a printed circuit board.

Damaged 3s Lipo

I've read the "stickyed" threads on damaged Lipos, and got my 3 cell back to 3.02, 3.00, and 0.70.
Is there a way to charge the one cell without overcharging the other 2?

Thanks,

JSflyer

Make a charge cord that connects to the balance connector for only the low cell.

Sandor, there aren't any boards in these little single cells. However if you carefully cut the plastic shield off you will find the plug has two short wires that solder to the cell tabs. You can:

a) desolder them. or
b) cut them off with side cutters.

Just do it one wire at a time and don't let the cell tabs/wires short out.

There is no need or likelihood of penetrating the cell itself.

You can also get the shield off the Turnigy cells which use hot glue by just heating the battery a bit with a hot air gun till it softens. May not work with batteries that use some other method of attaching the plastic shield.

Hope this is useful. I've also removed a couple of the plugs just by yanking the shield off, then cutting the wires but that's a bit drastic for the first time.

Hi Guys, having some 5 year daily experience with Lipos I find in above posts that lot of you are playing with the "FIRE" trying to recover bad cells. The most importantly is you should not bring the voltage bellow 3.7V per cell if you want long lasting reliable power supply, Joe.
