Mastervolt Mastervolt Battery Lithium Ion 12V 90Ah 1.2Kw

Description

The Mastervolt MLI-E 12/1200 Lithium Ion Battery (12V 90Ah / 1.2 kW) delivers advanced energy storage performance for demanding mobile, marine, industrial, and off-grid applications. Positioned between the compact MLS series and the high-capacity MLI Ultra range, the MLI-E provides exceptional power density, long lifespan, and robust safety features in a compact footprint.

Built with Lithium Iron Phosphate (LiFePO4) chemistry, the battery offers unmatched reliability and safety. The MLI-E provides up to 70% savings in weight and space, recharges in under one hour, and delivers up to 5,000 deep cycles, lasting up to 10 times longer than traditional lead-acid batteries. It is a direct drop-in replacement for a 180–200Ah lead-acid battery, making upgrades simple and efficient.

Equipped with an integrated safety switch and internal protections against overcharge, deep discharge, and overheating, the MLI-E requires no external relays. The tough plastic case provides strong resistance against vibration and physical impact.

For intelligent power management, the MLI-E includes a built-in battery monitoring system with LED indicators, remaining time display, and state-of-charge data. It supports NMEA2000 / CZone, CANopen, and integration with MasterBus (using EasyView 5). It also includes Bluetooth connectivity for hands-on monitoring through a mobile app.

Designed for mobile environments such as RVs, campers, expedition vehicles, maritime systems, off-grid cabins, and industrial installations, the MLI-E delivers dependable power wherever performance and safety are critical.
