Frequently asked questions
Will the External 17.5Ah Long-Range Spare Battery fit my e-bike?
It is a 48V pack, so the bike must run a 48V system. Beyond voltage, the case or mount, the discharge connector and the charger port must match, and the BMS rating must cover the controller's peak current.
How far will a 840 Wh battery go?
About 42 to 70 miles depending on assist level, terrain and rider weight (12 to 20 Wh per mile).
Is $700 good value?
Lectric lists it at $0.83 per Wh. The median 48V pack we track is $0.39 per Wh, so this pack is above the median.
