Robust & Affordable
Safe by Design
Extended Cycle Life
This robust 12 V battery is based on Lithium Iron Phosphate chemistry. As a result, these batteries are safe and reliable. Additionally, the next level technology of this chemistry results in a high energy density. In other words, it is the ultimate choice to replace your lead-acid batteries. Moreover, easily expand your battery storage system by connecting the LFP 12 V lithium-ion batteries in parallel. This increases the system capacity. To sum up some typical 12 V applications: motorhomes, rescue trucks and small luxury yachts. To complete your MG energy storage system, include one or more MG Master battery management controllers. This ensures a plug-and-play installation and safe operation. Additionally, you can connect multiple MG Masters in parallel to create a redundant system. This increases the reliability of your battery system.

Robust Design
The metal housing makes this 12 V battery solid and impenetrable. In addition, a metal enclosure serves as a strong EMC radiation protection. As a result, this Lithium Iron Phosphate battery is impact resistant and safe in operation.
Compact and Lightweight
Thanks to its design, this battery is suitable for installations in limited space. Besides, the next generation Lithium Iron Phosphate chemistry results in a high energy density. This reduces the weight substantially.
MG Connect App
Monitor and control the MG battery system with your smartphone or tablet. Download the MG Connect app in the Play Store or App Store and enable bluetooth. Get insight into the battery status and energy consumption. It is also possible to change settings, read-out events and update to the latest firmware.
Plug and Play
Easy installation with automatic configuration. Plug in the CAN-Bus of each battery module into the MG Master LV. This will automatically detect your configuration and install new firmware when available. The NMEA2000 CAN-Bus communicates with other equipment such as MFD displays, chargers and inverters, alternator controllers and more.
