I’m attempting to replace the sealed “proprietary” battery in a Serfas true lumen 750w bike light.
Because I’m cheap and stubborn I refused to buy the sealed unit.
I cracked open the case to find a 22650, 3.7v 3000mAh LioN. I can’t seem to source a replacement anywhere.
I’m a stuck using this size, as it fits in a proprietary housing, it also I need something with quite a large capacity.
I’m in Canada, short of ordering from Alibaba I’m not sure what to do.
