EMP [48V or 52V] Naked Lithium Battery Pack – Multiple Capacity Options
The EMP Naked Pack is built for serious riders who need reliability, safety, and performance. Every pack is assembled in the USA with premium high-drain 21700 cells from Samsung (50S) and Molicel (P50B). We test and balance every cell before assembly, so nothing sits on the shelf — you get a fresh, custom-built battery every time.
EMP Naked Packs include flame-retardant fish paper insulation, nickel-copper tab structures for high current draw, and a Deligreen/Daly BMS matched to the build. These packs are perfect for e-bikes, scooters, and light EVs that need higher discharge and long cycle life.
