Anyone managed to fit a new battery to a set of ProComs yet?

I've done it with lots of other things. My shaver for example, swapped the weak 18650 1.2ah cells for 3ah.

 

Years back I did it on several bluetooth headphones, they had 60-120mah little lipo pouch cells. I did upgrade a couple with much larger cells, I had to modifiy the plastic case. The better one, I took the case off entirely and set it in epoxy - it needed to fit in motorbike lid, great until it fell down a storm drain.

 

Basicically anything thats not using 18650 cells is likely to be lipo pouch cells. However there are some new types to be aware of - instead of a max voltage of 4.2v, some now go upto 4.35v.

If you put a standard 4.2v cell in a 4.35v device, you are likely to get fire. The old one should be marked, also you can measure it when fully charged to be sure.
