FAQs About eBike Lithium Batteries
1. How long will my eBike battery last? (Cycle Life & Total Lifespan)
A: Our eBike lithium batteries use high-quality BAK cells with a cycle life of 800–1,500 cycles (to 80% capacity retention). Under normal use, this translates to 3–5 years of reliable service life. The built-in BMS actively manages charge/discharge to maximize long-term performance.
2. What’s the actual range? Will it match the listed specs?
A: Real-world range depends on motor power, rider weight, terrain, and temperature. Our batteries are tested under standard load conditions to ensure a ≤10% deviation from rated capacity. For example, a 36V 10Ah battery with a 250W motor delivers a consistent 30–40km range.
3. Are these batteries safe? What about swelling or fire risks?
A: Safety is our top priority. All batteries use UL-certified Li-ion cells with built-in multi-level protection: over-charge, over-discharge, over-current, short-circuit, and thermal control. They are fully tested and certified to CE/UN38.3 standards to eliminate swelling and fire hazards.
4. Will the battery fit my eBike model or controller?
A: We offer highly customizable options to match most setups:
- Voltage: 24V / 36V / 48V / 52V
- Capacity: 8Ah to 20Ah+
- Form factor: Down tube, rear rack, or custom case designsOur batteries are compatible with most Bafang, BBS, and common controllers. Contact us with your specs for a tailored solution.
5. How long does charging take? Do you offer fast charging?
A: Standard chargers (2A–5A) fully charge a 36V 10Ah battery in 2–3 hours. We also offer optional 10A fast chargers, which cut charge time to just 1.5 hours, without compromising battery health. All chargers support balanced charging to extend pack life.
6. Can I use the battery in cold weather?
A: Standard models work reliably down to -10°C. For cold climates, we offer low-temperature variants rated to -20°C / -40°C, using specialized cells and BMS temperature compensation to minimize range loss in extreme cold.
7. What’s your warranty policy? Can you repair faulty batteries?
A: We offer a 2-year warranty on all eBike batteries. During the warranty period, non-human-induced failures are covered for free replacement. For out-of-warranty issues, we support module-level repairs (instead of full pack replacement) to reduce your maintenance costs.
8. Are the batteries waterproof? Can I ride in the rain?
A: Our battery packs feature an IP65 waterproof rating, which protects against splashes and light rain. They are designed for daily commuting in wet conditions. Note: Never submerge the battery in water, as this will void the warranty.
9. How do I maintain my battery to extend its life?
A: Follow these simple tips:
- Keep charge level between 20–80% for long-term storage
- Avoid fully discharging the battery regularly
- Store in a cool, dry place (15–25°C is ideal)
- No “first charge activation” is needed — charge as you normally use it
10. Can you ship these batteries by sea or air? What certifications are required?
A: All our eBike batteries come with full UN38.3, MSDS, and shipping documents required for sea and air transport. We handle all compliance paperwork to ensure smooth delivery to your destination.
