No need to worry about heating as @pichlo described.

And if it becomes so hot that it might damage the battery without isolation, it will also harm it with the isolation.

Exactly. Just make sure the strips are at least 2mm wide and you will be fine.

If success, could you please also share components and where to buy? I'm not counting on my JC battery to last forever. ;)

And please make a few pictures if possible :). So others can reproduce it too.

Sure, I will take some pictures :)
This is stuff that I purchased. The glue only today, don't know why I didn't think about this brfore :)
The foil already arrived, the battery I hope the next week. Probably I will start without glue (banding of foil + strip of isolation band to hold it in the place) until I will get it...

Hi everybody,

as there is no spare battery available for the JollaC outside of India.

I wrote a short tutorial on how to make the UMI X2 battery JollaC compatible. A big thanks to TJC user Giacomo Di Giacomo who gave the tip in the spare battery thread that it fits the JollaC.
You're welcome. I just knew today about this thread. I don't read often here on TMO.

1. We can use both sides of battery to put the foil (or i'm wrong ?) In this case we have only one cross of foils that can be isolated with small patch of something..
2. About bad connection of foil, I will check when I will get my new battery.
You are right. This is what I want to do in my next try. One strip of copper foil per side, and a wire for the thermistor (centre contact). I hope to improve high-current transient performance.

Don't worry, foil won't heat. Wrap it in Kapton tape to make sure it won't tear off.

Is your battery arrived in the meantime? Does it work without glue? If it work, can you post some pictures please? Unfortunately some days ago my battery double the size and I'm looking for solution :mad:

Unfortunately the battery of my JollaC doubled the size :mad: some days ago, so I'm very interested in an alternative battery :)
