Who Makes The Battery?

Battery Details

What are they?

KnightBikesElectric uses premium lithium-ion cells to construct our battery packs.

Batteries are constructed with Samsung cells. Our batteries have a life expectance of 5 years before significant decrease in battery capacity and voltage outpout.

Yes, KnightBikesElectric ships our batteries separate for shipping regulations. When transitting packages to international countries, our package goes through customs faster when shipped separately.


Yes, you can purchase another battery for longer riding fun. We recommend not riding around with the secondary battery in a backpack because it's extremely heavy.

Crashing or falling can also damage/destroy the expensive battery. KnightBikesElectric does not cover the warranty for the battery being damaged by user error.

Swapping the battery takes roughly 5 minutes.

Tools required for the job,

Metric Allen keys to screw off the side panel, remove old battery, load secondary battery, plugin in the main power and BMS cable.

Congrats your ready to double your range.

What cells?

KnightBikesElectric uses premium 18350 lithium-ion cells. The cells are rated for 1500 charge cycles. We give all customers a 12 month battery warranty.

Do we make them?

KnightBikesElectric builds our own batteries for our ebikes. Quality control is very important to us. Our warranty is valid for one year on all electrical components.

Yes, all lithium batteries sold in the United States must have an IFTA license to conduct business legally. Rest Assured our batteries have been tried and tested.

Terms & Service

Battery cell safety testing services

Manufacturers and consumers want trustworthy assurance regarding the performance, reliability and safety of battery cells used in an ever-growing number of products.  We offer a targeted array of services designed to give all stakeholders increased confidence in these products.

Testing lithium-ion cell battery separators

We test and certify lithium-ion cell battery separators to UL 2591, Outline of Investigation for Battery Cell Separators, or custom test protocols to help ensure battery integrity and safety meet the capabilities and demands needed to compete safely in today’s market.

In-house EMC compatibility and battery cell certification

Our electromagnetic compatibility (EMC) service enables you to optimize your own in-house testing capabilities to identify and resolve EMC problems as early as possible.

Battery cell safety testing and certification: Using application-based standards and local country marksBattery cell and related testing standards 

Traditionally, battery cells have been certified to UL 1642, the Standard for Lithium Batteries.  Widely known to apply to lithium-ion batteries, this Standard focused on portable consumer applications.  It was not tailored to the needs of motive or stationary applications.

With the recent development of robust safety standards for newer battery applications, we can now certify cells for use in motive, transportation or stationary applications to the corresponding application-based Standard: UL 2271, the Standard for Batteries for Use in Light Electric Vehicles (LEV) Applications; UL 2580, the Standard for Batteries for Use in Electric Vehicles; or UL 1973, the Standard for Batteries for use in Stationary Vehicle Auxiliary Power and Light Electric Rail (LER) Applications.  This means fewer samples required for testing, reduced conditioning requirements and increased overall speed to market.

We help you achieve global market access with advisory services, testing and certifications to UL Standards specific to batteries, electrochemical capacitors, fuel cells and related energy storage technologies.  We also assist with transportation and regional standards, as well as assist with obtaining local country marks, including:
