Where to find a non-standard LiPo pouch battery?
(1/2) > >>
e100:
This is a protected 3.7v LiPo cell from my bicycle LED light.
The current dimensions are 55 x 27 x 11mm and the original capacity was 2000mAh.
The black adhesive foam piece is there for padding.

It doesn't look particularly bloated so I imagine that a new replacement cell would be very similar in size, however my google searches aren't finding anything so presumably it was a custom size made for that particular model of light.

tooki:
See the “112556” printed on it? That’s almost certainly the nominal dimensions: 11 x 25 x 56. Searching for those dimensions, or for the size code,  may be more fruitful.
cruff:
I tried a search and did not find anything obvious. Lots of other batteries of other sizes though.
tooki:
I found some mentions of them, so they do exist, but I didn’t search for vendors.

What certainly seems to be a lot more common is 112560, i.e. 5mm longer. OP, would that potentially work? If you’ve got those 5mm to spare, then the slightly longer version would be a simple replacement.

If not, you could sacrifice a bit of battery life and install a slightly smaller battery, like the common 102050.
Infraviolet:
I don't believe there actually are standard sizes for pouch cells?
