The Mastervolt MLI-E Lithium Ion battery closes the gap between the very compact MLS battery and the successful high capacity MLI Ultra series. The MLI-E is ideal for applications where long lifespan, lightweight, fast charging and compactness are key. Its practical form factor makes the MLI-E perfectly suitable for mobile applications.

Lithium Ion has many advantages over lead-acid. The MLI-E saves up to 70 % in space and weight, recharges in less than an hour, and deep cycles 5.000 times easily, which is up to 10 times longer than lead-acid batteries. The MLI-E can replace a 180-200 Ah lead-acid battery. Also, for the MLI-E the extremely safe Lithium Ion (LiFePO4) chemistry is used.

No external safety relay is needed. The MLI-E is protected against overcharging, deep discharging and overheating and comes with an integrated electronic safety switch. With its waterproof plastic case, the MLI-E is a straight-forward replacement for most lead-acid batteries.

LED indicators inform you about the actual status of your battery. Of course, the MLI-E is provided with integrated battery monitoring, including information about state of charge and time remaining. For optimal integration in both mobile and maritime power systems, both NMEA2000 / CZone and CANopen protocols are supported. Needless to say, the MLI-E fits perfectly into a MasterBus system, when combined with our system monitor EasyView 5*. And last but not least: hands-on monitoring is available, using Bluetooth and a mobile app.


  • Very long lifespan, maintenance free.
  • Fast charging and discharging, fully charged within an hour.
  • Straight-forward replacement for most existing lead-acid batteries (EqPb: 200 Ah).
  • Compact, practical size.
  • Extremely safe Lithium Ion chemistry (LiFePO4).
  • Integrated safety switch for quick and easy installation.
  • High performance even under harsh conditions.
  • High efficiency and low self-discharge.
  • Integrated battery monitoring for reliable battery status information.
  • System integration via NMEA2000 / CZone, CANopen or MasterBus (via EasyView 5*).
  • Monitoring via Bluetooth app possible.
