EMP 72V Naked Lithium Battery Pack – Multiple Capacity Options

The EMP Naked Pack delivers extreme performance and reliability for high-voltage builds. We assemble every pack to order in the USA using premium high-drain 21700 cells from manufacturers such as LG, Samsung, and Molicel. Cells are tested, balanced, and matched before assembly so you always receive a fresh, safe, and high-performing battery.

Unlike mass-produced imports, EMP Naked Packs use flame-retardant fish paper insulation, nickel-copper tab structures for high current handling, and a custom BMS that’s matched to the exact series/parallel configuration. These packs are ideal for high-performance e-bikes, racing scooters, and custom LEVs that need strong voltage and current delivery.
