Description
The Epoch BB72105A is made for higher-voltage golf carts that want both range and serious power on tap. With 105Ah of LiFePO4 capacity, 7.392kWh of stored energy, and a rugged steel case, it’s a substantial upgrade without getting overly complicated.
Key Features
-
105Ah / 7.392kWh Capacity: Gives 72V-class carts plenty of stored energy for longer drives and fewer charging stops.
-
Bluetooth + Display Monitoring: Keep an eye on voltage, state of charge, and current from your phone or the included display.
-
Big Current When Needed: Delivers up to 250A continuously and can push 1,000A for 2 seconds when acceleration or heavier loads call for it.
The BB72105A uses a 1P22S LiFePO4 configuration with a 70.4V nominal output. It’s built for compatible high-voltage carts that need more than just decent range, with enough current capability to keep performance feeling lively.
Its steel enclosure is rated IP67, so dust and water are much less of a concern when the cart spends its time outdoors. Charging is supported from 0°C to 55°C, while discharge operation stretches from -20°C to 60°C.
Up to two batteries can be connected in parallel if more capacity is needed down the road. With 3,500+ rated cycles and an 11-year manufacturer warranty, the BB72105A is built for carts that are expected to do more than cruise around the driveway.
