For sale is a 52‑volt, 17 amp‑hour shark‑style Ebike battery with a 30‑amp BMS, originally purchased from Electrify Bike Co. in January 2026.

Details:

• Voltage: 52V
• Capacity: 17Ah
• Style: Shark / downtube style
• BMS: 30 amp
• Connector: XT90
• Charge Cycles: Only 2 charge cycles
• Includes: Battery, mounting cradle, and charger

Condition:

The battery is nearly new and functions perfectly. It does have a cosmetic wear mark on the top of the case, caused by brief tire contact when test‑mounted under the downtube. This was only during fit testing—there is no damage to the battery, wiring, or performance. Can be used in a 48 volt system,

Reason for Sale:

I originally built a bike that later developed a cracked frame. After sourcing a replacement frame and rebuilding the bike, this battery no longer fits on top of the downtube, and mounting it underneath doesn’t provide enough tire clearance for my setup. I’m switching to a smaller 10–13Ah battery strictly for fitment reasons.
