Hi folks,I'm not very electrical minded. I have this lamp (https://www.ebay.com/itm/263711644964) on my electric bike but it doesn't get used any more. If I wanted to fit it to my regular bike, could I power it with 18650 cells and if so how many would I need in tandem to get it to run? I don't mind less than full power, it's very bright already. It's a good light.Thanks!
Pomsbz, the specification on the ebay page claim it operates from DC 12V-80V, how do you used to supply the power to this light from your electric bike or do you know how many volts is your electric bike supplying to the light? Is your electric bike running on something like a car battery?I think it may be possible to use 18650 to power this, but just want to make sure there is enough power and the current draw is not too high so the batteries get too warm too quickly.Another way is simply to ask the seller whether this light can be run on 18650(protected?) and how many cells are needed.
The bike battery is 48V (I think). To be honest I think I'm just going to stick with a flashlight. I bought this bracket https://www.ebay.com/113812182929 and I'll just stick one of my BLF A6 SE's on it.
The light only needs 12V, not the full 48V of the bike battery. I've been riding for the past couple of nights with just a flashlight and it's been more than fine actually!
