If you go the route that Chalo is suggesting, you can just buy a 12V battery to power the lights and an appropriate charger for it. You don't need to use a buck converter unless you are stepping down the voltage from a higher voltage battery like those used in ebike kits.
I guess I missed that, but I see it now.When I see a BBS02, I assume the presence of an e-bike battery.
It isn't a bad idea to have a backup source of 12V power to keep you lit in case of a flat battery or an electrical issue, though. A small 4S LiFePO4 pack can serve this purpose while using regular 12V charging equipment designed for lead batteries.
This sort of depends on how comfortable you are running battery voltage to the front and rear of your bike. I use a high voltage front only because there's a battery level voltage output available with the CA3. It's either one buck converter running 12V around the bike, or several buck converters built into the lights and running 72V around the bike.There are headlights (with a switch and horn) out there that work with voltages up to 72v. There are plenty of headlights/taillights (with turn signals) that work with voltages upto 48v (some even 60v). However most of these do not meet the German standards for cycling lights.
As you have pedals, you may use this without power. And one day when you are not home, you will so you can get home and work out how the power failed.enclosed pedal car and would like to install operable headlights and tailights.
