48v 15Ah Li-ion Downtube E-Bike Battery

• 48V 15Ah lithium-ion downtube battery — powerful, long-lasting energy for E-BikeKit systems
• Downtube-style, key-lock mount for secure attachment and easy removal
• Includes 3-amp charger — ready to use out of the box
• Connector compatibility: Uses the current E-BikeKit 5-pin twist connector.
  Older controllers with a 2-prong male connector will require a simple adapter.

This is our longest-lasting standard battery option, offering excellent range, reliability, and everyday usability.

The E-BikeKit 48V 15Ah Li-ion Downtube Battery Pack delivers a strong balance of power, range, and durability for commuting, recreation, and light cargo use.

With an expected 500–800 full charge cycles, this battery is built for years of dependable riding. The downtube design keeps weight low and centered for stable, confident handling.

The integrated key-lock mounting system secures the battery to the bike while allowing easy removal for indoor charging or storage.

Connector compatibility: This battery uses the new 5-pin twist connector found on the latest E-BikeKit controllers.
If your current controller has a 2-prong male connector, an adapter is required. This is a simple solution, and our team can help confirm compatibility before ordering.

Installation: Many riders install this battery themselves with basic tools. A local bike shop can also handle installation quickly and easily if preferred.

Shipping note: Lithium-ion batteries ship separately from electric bike kits and are sent via FedEx Hazmat. A delivery signature may be required. It’s normal for your kit, battery, and mounting hardware (if applicable) to arrive on different days.
