MasterVolt Batteries – Lithium Ion MLS

The MLS series has been designed with technology from the huge success MLI Ultra. Although designed for different types of applications, the MLS has many of the same characteristics as MLI, making them great for applications where very long lifespan, light weight and compactness are essential.

Compact batteries, high energy storage capacity, long lifespan = ideal replacement for lead acid batteries.

Lithium Ion has really many advantages over lead-acid:

  • The MLS series can fast recharge in an hour
  • And deep cycle (up to 80 % discharge)
  • 2.000 times without damage. It is three times longer than traditional lead-acid
  • For MLS the safest Lithium Ion chemistry available (LiFePO4) is used.

The MasterVolt MLS has build in battery management system that includes a safety disconnect that protects the battery from too deep discharging, overcharging and overheating.
The MasterVolt MLS makes an ideal energy storage solution, and it create an optimal entry point shifting to Lithium Ion from Lead/Acid.
