Frequently asked questions
Will the EM3ev 48V 20Ah King Shark battery fit my e-bike?
It is a 48V pack, so the bike must run a 48V system. Beyond voltage, the case or mount (King Shark), the discharge connector and the charger port must match, and the BMS rating must cover the controller's peak current.
How far will a 960 Wh battery go?
About 48 to 80 miles depending on assist level, terrain and rider weight (12 to 20 Wh per mile).
Is $379 good value?
EM3ev lists it at $0.39 per Wh. The median 48V pack we track is $0.39 per Wh, so this pack is above the median.
