hi folks
i have a robot with 2 batteries one for (axon micro controller ,a small devices,sensors) it's Ni-Mh 6volt (5x1.2volt AA 2200mA) battery and the other is 6volt 4Ah sealed lead acid battery for motors and current consuming devices i need to make a circuit to charge both batteries with a 9-12volt AC Adapter and disconnect the axon and the devices during charging and light green led when fully recharged also need to monitor battery charge to tell the micro controller the battery life during operation this could be a separate circuit but at the moment i'm focus on the charging circuit. anyone can help me?
Thanks
