would it be possible to have the trolling motor battery hooked up to dc outlet and then maybe getting a on board charger connected to run a loop and be able to keep that battery fully charged for all day trolling. It only last about 8-10 hours and then it looses juice. Someone told me and would need some sort of converter to the 12 volt battery then i can use the ac outlet to plug a battery charger to it.
