I have an odd application. I Need to be able to hook my motorcycles to my truck to charge the battery an warm them up I ride them in super cold (-35*F) and need to find way to hook the truck to the bikes but only limit the current to 10 Amps to each bike. They both have LIFEPO4 Batteries. The only sure fire way to do it it to hook up an inverter in the bed and run a LIFEPO4 charger from that but I know theres got to be a better way. Please point me in the right direction.
