I got a Bafang BBSHD motor, which has a light cable output of 6V 0.5A = 3W which isn't enough for any decent light. I bought a really great e-bike light 6V that requires 12W, so 2A output instead of 0.5A. For this reason I think to connect it directly to my 48V battery using a DC-DC converter. The thing is, I cannot find any decent DC-DC 48V to 6V 2A for doing what I want...
The best I could find is this: https://www.aliexpress.com/item/High-Voltage-EBike-DC-DC-Converter-Buck-Step-Down-Regulator-Module-80V-72V-64V-60V-48V/32824239630.html?spm=2114.search0104.3.2.7d88e2e0dNCMpR&ws_ab_test=searchweb0_0,searchweb201602_1_10152_10065_10151_10344_10068_10342_10325_10343_10546_10340_5722611_10341_10548_10698_10697_10696_5722911_5722811_10084_5722711_10083_10618_10304_10307_5711211_10059_10184_308_100031_10103_441_10624_10623_10622_10621_10620_5711311_5722511,searchweb201603_28,ppcSwitch_5&algo_expid=93281559-2926-49f7-b9f6-52c07e8b625b-0&algo_pvid=93281559-2926-49f7-b9f6-52c07e8b625b&priceBeautifyAB=0
But it outputs 6V 1A = 6W which is half of what I need. Please help me somebody.
