Midnite battery capacity meter


An easy to install and use LED battery state of charge meter. Based on battery voltage over time. Multi-voltage (12, 24, 36 and 48V).



MidNite Solar has a new battery capacity meter! It’s probably the easiest to install and easier to read than any other battery meter. You simply connect the negative (-) and positive (+) wires from the meter to the battery terminals. The meter will go through a start-up test sequence when power is first applied. Once the test is complete, the meter is ready to use. Don’t forget to use a 2 Amp fuse or circuit breaker on the positive wire. It’s that simple!
