Battery Isolators

Charge several batteries efficiently from one alternator or charger, without voltage drop and without current flowing back between batteries.

LieMo Battery Isolator
01

8-30 VDC

Suitable for 12V and 24V installations and usable in wider DC systems.

02

2 or 3 outputs

Available for installations with several battery banks of the same nominal voltage.

03

No voltage drop

No diode compensation needed, so batteries can be charged fully.

Features

  • Distributes charging current efficiently across several batteries.
  • Prevents current from flowing from one battery to another.
  • No effect on the charging characteristics of the charger or alternator.
  • Suitable for lead-acid and lithium batteries.
  • Easy installation: in the positive supply line only.

Installation principle

The Battery Isolator is connected between the alternator/charger and the battery banks. The negative connection runs directly to the batteries; the distribution takes place on the positive side.

Mounting instructions4 steps for safe installation
  1. Disconnect the negative battery terminal to prevent short circuits.
  2. Mount the converter in a well-ventilated place using the screws supplied.
  3. Connect the trailer wiring to the 12V output and the vehicle lighting to the 24V input.
  4. Connect the incoming and outgoing ground to a common ground point near the unit.

Battery protection

Voltage Guard

Protects the battery and installation against deep discharge, overvoltage, overload and overheating by automatically disconnecting loads.

LieMo Voltage Guard 70

Why choose Voltage Guard?

  • Protection against deep discharge through automatic disconnection.
  • Automatic voltage detection for 12V and 24V systems.
  • Adjustable low-voltage threshold.
  • Damping against voltage spikes prevents unnecessary disconnection.
  • Solid-state technology: energy-efficient and maintenance-free.
  • A multicolour LED and an audible alarm show the battery status.
Green LEDBattery voltage optimal, output switched on.
Orange LEDVoltage below threshold, disconnection after 30 seconds.
Red LED + alarmSwitched off due to low/high voltage, overload or overheating.
