Replacement 36V 10.4Ah battery of the rack type as seen on Knaap-style fatbikes. A 1-to-1 replacement with the same voltage — your existing charger and controller keep working. 18650 Li-ion cells and a built-in BMS protect against deep discharge and overcharging. RideParts does not sell tuning kits; this is purely restoring your original range. Send us a photo of your cradle and connector and we'll help you match it.
Compatibility is indicative data based on platform research — check the specifications or ask us if in doubt.
