Hi , I am looking to make a 24volt 60watt system. With two 12volt 7amp batteries in series. I want to wire in a charging port and use a 24 volt scooter charger to charge the batteries. My question is would i be able to follow this simple circut to charge the batteries and would i have to disconnect them from the amp when charging. The 24 volt motor is replaced by a 24 volt dc amplifier, just to be clear. Any advice would be greatly appreciated , thanks.
Im interested in putting one of these together within an old ammo can and using some good qulity car speakers. Iv been looking at the topping tp22 (tk2050) and two scooter batteries . However this has a wall wart set to 20V at 3A i was wondering would i wire the datteries directly to the amp at 24 volts or to the wart or do i need a seprate peace of kit to get it working ?
