DMM-4 Battery Monitor-Microlog

  • The Microlog DMM-4 Battery Monitor is  designed to monitor the level of charge for 3  battery banks in measuring the total Battery Cells Voltages with great precision.
  • The voltage monitoring inform you of the state and condition of your batteries, charging equipment and also when it's time to charge and stop charging.

Charge and discharge current monitoring: (as option)

  • With the shunt kit SWK-201 (sold separetely), the Microlog DMM-4  System will also monitor the intensity (Amperes) of incoming current from charging equipment such as alternators, wind generators or solar panels and/or, current consumed in your boat.
  • You can measure just charging or just discharging current if you prefer; or NET current circulation to your house bank.


  • Protects your batteries against deep discharge
  • Accurate 3 battery banks voltage measurement
  • System Charge, Discharge or NET current measurement(with optional Shunt)
  • Voltage up to 20VDC @ 0.01V Resolution on 12VDC model
