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 Samsung (50S) and Molicel (P50B). 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 Deligreen/Daly 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.
