100 mW
So I've been looking for ways to power my headlight for my ebike DIRECTLY from the battery, with a device through it probably. These days, I power my ebike with 1 18650 cell, and needs to recharge it seperately. I want to have an output from my battery (48v) step down to 5v for some low voltage uses such as phone charger, alarm, lights, horn, etc. I found a step down board called lm2596, but It's limited to 50v, while a fully charged 48v battery can go up to 54.8v, and I'm afraid of damaging it. Maybe some ebike controllers do have a 5v output for these, but I'm using some chinese bldc controller, that seemed lack of this feature. Maybe any other solutions you all have? Hope I can find a way...
