Arduino based battery capacity and internal resistance tester
2 Modes are available at booting:
- Capacity Test Mode
- Internal Resistance Test Mode
Main parts being used:
- Uses Arduino Pro Mini.
- Uses Philips PCD8544 (Nokia 5110) Display (84*48 dots).
- Uses 2 Ohm power resister (10W) as shunt. Load can be added in series via screw terminal.
- Uses logic level N-channel MOSFET (IRLR3103) controls shunt.
