charge a battery while using it?
hi, i'm looking for a way to charge a 12v deep cycle lead acid battery while powering an amplifier from the battery. Can i literally just attach the battery charger to the battery as well as the amplifier as long as the connections to the amplifier and charger do not touch? or is it not that simple?
The instructable linked above is what i what to implement it into. Any help will be appreciated!
