The system will charge the batteries (can you make this system charge more than 1 battery) (6V or 12V or 14V). The system will use 120VAC input socket, and the output voltage will be stable to charge these kinds of battery. The system will use LM3S1968 chip to control all the system. The CPU LM3S1968 will calculate and show the each battery percentage. And also add thermistors and send signal to LM3S1968 chip to show the current temperature on the LCD (Add LCD to this circuit).
I think this battery system will need a transformer, diode bridge, 4 NPN transistors, 1 LCD..... Can you draw that system complete (Schematic and PCB) using PCB Artist?
Please suggest the price for this if you would like to do this one. I will send to you stater files .sch and .pcb (PCB Artist) when you agreed that you want to do this.
