Expandable Power

Ability to add capacity ranges based on customer needs by connecting packs in parallel. For example, five 5kWh packs can be connected together for 25kWh of energy.

Safer Power

The Battery Management System (BMS) has features engineered to monitor the voltage and temperature of each CMA to make sure that it is operating within the nominal range for safety.

Passive Propagation Resistance

Tier plates are used to separate each Cell Module Assembly so that if one cell has an issue, it cannot propagate to neighboring cells.

Lighter In Weight

The new diecast enclosure is 20% lighter in weight compared to the 5kWh roll cage battery.

Assembled in the USA

All battery packs are assembled at our advanced battery manufacturing facility in Tucker, Georgia.

8 Year Commercial Limited Warranty

Vanguard now offers an 8 year commercial limited warranty for all lithium-ion battery packs. CLICK HERE for more information.
