48V E-Bike Batteries FAQ

Is there a standardized 48V lithium battery for e-bikes?

There is no uniform standard for 48V lithium batteries. CMB’s professional engineers customize these batteries to ensure they are compatible with each client’s unique products.

What are better for e-bikes, lead-acid batteries or lithium batteries?

Lithium batteries are a wiser choice for e-bike applications because of the below key reasons.

Longer range: Lithium batteries can provide electric bikes with a longer range than lead-acid batteries, which is important for riders traveling long distances.

Lighter weight: Lithium batteries are lighter than lead-acid batteries, which can improve the performance of electric bikes and provide a more convenient user experience for riders.

Faster charging: Lithium batteries can be charged more quickly than lead-acid batteries, which is convenient for riders who need to recharge their batteries on the go.

How long do 48 volt lithium battery for ebike last?

If taken care of properly, you can expect a battery to last between 3 and 5 years. (Even if not used, a lithium-ion battery will lose its capacity over time.)

How well do 48V e-bike batteries perform in extreme temperatures?

CMB’s e-bike batteries perform well in temperatures above room temperature. In extreme temperatures, CMB’s batteries perform better than other batteries in regard to efficiency. Although our 48V e-bike batteries have protection from high temperatures, we advise e-bikes to be kept at or around room temperature, as exposing battery packs to high temperatures on an ongoing basis can damage battery cells.

What experience does CMB have manufacturing 48V e-bike batteries?

For more than 10 years, CMB has been manufacturing custom high-performance e-bike batteries for clients all over the world. Our e-bike battery packs contain useful correspondences including UART, CANBUS, Ethernet, and Bluetooth.
