Frequently Asked Questions
Q1: Do your e-bike batteries come with a charger and BMS?
A1: Yes, all e-bike batteries include a standard charger (fast charger available on request) and a protective BMS to safeguard against short circuits, overcharging, overdischarging, and overcurrent.
Q2: What is the estimated delivery time?
A2: Standard electric bike batteries are typically dispatched within 5 days after order confirmation, with delivery taking between 3 to 15 days depending on the quantity and specific requirements.
Q3: How long is the expected lifecycle of the battery?
A3: The battery features a cycle life of about 800 to 1200 cycles, lasting roughly 2 to 3 years. It is recommended to replace it when capacity drops below 75% of the original rating.
Q4: How should the battery pack be maintained?
A4: Store the battery in a clean, dry, ventilated, and shaded environment. Make sure to store it fully charged and recharge it every 3 to 6 months when not in active use.
Q5: What are the advantages of Li-ion batteries over NI-MH and Lead Acid?
A5: Li-ion batteries offer a longer lifecycle (typically 600-800 cycles), lighter weight, smaller footprint, no memory effect, and a more environmentally friendly design.
Q6: Do you offer customization or OEM/ODM support?
A6: Yes, we provide full OEM and ODM services to manufacture custom lithium batteries based on your unique specifications and designs.
