e-Bike Batteries: Which one to Choose and Safety Tips
Share
Nothing beats a great ride. With an e-bike, the fun in your day can last a lot longer than with pedalling alone. And nothing hurts more than finding your battery is dead as soon as the fun starts.
How can you keep this from happening? What battery is best to get, anyway?First, we have a ready reckoner to help you choose a battery, and then we share a few tips to extend the life of your e-bike battery and protect this very valuable part of your investment.
Choosing the Right e-Bike Battery
Your e-bike battery size significantly impacts range and performance. Here’s a quick breakdown:
- 36V batteries: Standard for urban commuting and leisure riding. Best meet Queensland e-mobility compliance standards.
- 48V batteries: Provide more power and support larger torque motors, suitable for hilly terrain, off-road use and heavier riders. Typically non-compliant for shared pathways in Queensland (check for compliance to EN15194 Standard)
- 52V batteries: Offer superior efficiency and range but may require special controllers. Typically off-road, e-motorbikes and on-road registered motorbikes.
For a power assist setting on the controller of economy riding along a typical flat, sealed pathway, the battery range is generally:
Please note: The range is variable (shown by error bars) and dependent on operator use, the power assist setting on the controller, the total weight of the rider + bike + load, battery age, battery storage, and battery care. The reckoner does not take into account riding steep inclines in hilly areas.
Best Practices for e-Bike Battery Care
1. Avoid Extreme Temperatures
- Store batteries in a cool, dry place.
- Avoid direct sunlight and extreme cold (below 0°C) or heat (above 35°C).
- Charge at room temperature for optimal performance.
2. Charge Smartly
- Avoid full discharges: Charge before reaching 20% and stop around 80% to extend lifespan.
- New batteries require an initial 8-12 hours to 100% charge before first use and repeated daily for the first week.
- Unplug once charged to avoid overcharging.
- Perform an occasional full discharge (every 30-40 cycles) to balance cells.
3. Regular Maintenance
- Check terminals and clean with a dry brush.
- Inspect electrical contacts and ensure connections are secure.
- Keep the charging port free of dust and dirt.
4. Proper Storage When Not in Use
- Store batteries at 40%-80% charge if not in use for extended periods.
- Recharge every 6 months to avoid deep discharge.
- Keep in fire-resistant storage when possible.
5. Recognizing When to Replace an e-Bike Battery
- Batteries have a limited lifespan (2-5 years). Typically ~4 years for properly maintained good quality batteries
- Signs of deterioration include:
- Reduced range or sudden power loss.
- Swelling, leaking, or overheating.
- Corroded terminals or inability to hold a charge.
If your battery shows these signs, replace it to maintain safe and efficient riding.
e-Bike Battery Safety Tips
1. Use Approved Equipment
- Always use the manufacturer’s recommended charger.
- Avoid cheap aftermarket chargers that may damage the battery.
2. Charge Safely
- Charge in well-ventilated areas away from flammable materials.
- Do not leave charging overnight or unattended.
- Install smoke alarms in charging areas for added safety.
3. Dispose of Batteries Responsibly
- Never throw lithium-ion batteries in household waste.
- Recycle at approved e-waste centres to prevent fire and environmental hazards.
Conclusion
By following these best practices, you can maximize your e-bike battery life, ensuring consistent performance and long-term savings. Whether you ride for leisure, commuting, or adventure, a well-maintained battery ensures you never get stranded.
