Audited Supplier
The GC2 battery has an integrated battery management system (BMS) that controls the parameters of the battery to provide optimum safety and performance. This enhanced design balances the battery cells and protects against overcharging or over-discharging. Plus, this battery features a fully reimagined, IP67-rated casing for comprehensive protection against dust, water, and other contaminants while you're on the road.
This lightweight and maintenance-free battery was engineered specifically to power golf cars, utility vehicles, and AGVs.
Lower Overall Cost of Ownership
You only need two to three lithium-ion batteries vs. six (8V) flooded lead acid in a 48V vehicle. Over ten years that equals 2-3 lithium-ion batteries versus 24 lead acid batteries.
