Frequently asked questions
Will the EM3ev 52V 20Ah King Shark battery fit my e-bike?
It is a 52V pack, so the bike must run a 52V 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 1040 Wh battery go?
About 52 to 87 miles depending on assist level, terrain and rider weight (12 to 20 Wh per mile).
Is $399 good value?
EM3ev lists it at $0.38 per Wh. The median 52V pack we track is $0.57 per Wh, so this pack is at or below the median.
