21.21kWh PACK

HL72 Series – 72V Lithium-ion Battery Systems

The HL72 series is a range of high-performance lithium-ion battery packs designed specifically for low-speed electric vehicle applications. Based on a nominal 76.8V platform, this series covers three capacity levels—12.28kWh, 15.51kWh, and 21.27kWh—to meet the precise energy needs of golf carts, light electric vehicles, multi-purpose work vehicles (UTVs), and automated guided vehicles (AGVs).

Each cell is manufactured using EVE lithium-ion batteries—EVE is one of the industry’s most trusted battery manufacturers—offering high round-trip efficiency, low internal resistance, and a lifespan of over 3,000 charge cycles at 80% depth of discharge.
