Electric Bicycle Battery Safety Guide 

As the global electric bicycle market continues to grow, electric bicycle battery safety has become a core concern for both users and brands. The battery is the core power source of the entire vehicle, and its safety directly affects the riding experience and brand reputation.

This article will provide you with a detailed guide on the safe use of electric bicycle batteries, helping brand customers and end-users to operate them correctly, extend battery life, and ensure riding safety.

Why is electric bicycle battery safety so important?

Although Lithium-Batterien are lightweight and efficient, improper use can lead to safety risks such as overheating, swelling, and even fire.
Battery safety problems mainly stem from:

Incompatible chargers or batteries

Overcharging, over-discharging, or prolonged use at low battery levels

Riding in high or low temperature environments

Improper installation or insecure fastening

Yizhan Electronics uses an intelligent BMS (Battery Management System) in its battery design to monitor voltage, current, and temperature in real time, ensuring that the battery operates within a safe range. Key Safety Precautions for Electric Bicycle Battery Use

1. Use Matching Batteries and Chargers

Voltage and capacity must match the vehicle’s motor (36V, 48V, 52V are common options).

Avoid using non-original or uncertified chargers.

High-quality BMS prevents overcharging, over-discharging, and overcurrent, improving safety.

2. Avoid Overcharging and Over-discharging

Prolonged discharge to 0% or prolonged charging to 100% will accelerate aging.

It is recommended to keep the battery level between 20% and 80%.

BMS automatically controls charging and discharging, extending battery life.

3. Installation and Fixing Specifications

Ensure the battery size and interface match the frame.

Loose fixing may lead to poor contact or damage.

Down tube, rear rack, or hidden batteries all require shock-absorbing and cushioning designs.

4. Waterproofing and Environmental Protection

Although batteries have IP65/IP67 waterproof ratings, prolonged immersion in water should still be avoided.

Check the interface after riding in the rain.

Avoid high temperatures, direct sunlight, or corrosive environments.

5. Regular Inspection and Maintenance

Check the battery casing, interface, and BMS indicator light status.

If swelling, odor, overheating, or abnormal noise occurs, stop using it immediately.

Yizhan Electronics batteries undergo capacity testing, aging testing, and safety testing before leaving the factory to ensure stable performance.

Electric Bicycle Battery Safety FAQ

1. What should I pay attention to when using the battery for the first time?

New batteries should be fully charged before first use to activate the BMS and calibrate the power display, ensuring accurate range.

2. Can batteries be replaced arbitrarily?

Different brands or models of batteries have different voltages, capacities, and interfaces. Unauthorized replacement may lead to abnormal power or safety hazards. It is recommended to use original or customized batteries.

3. What should I do if the battery overheats during use?

Stop using it immediately, move the battery to a well-ventilated and dry place, and contact professional after-sales service or the manufacturer for inspection.

4. How should I store the battery if I don’t use it for a long time?

Keep the battery level between 40% and 60%, and store it in a dry, cool, and well-ventilated environment, avoiding high temperatures, low temperatures, or humidity.

5. What role does the BMS play in battery safety?

The BMS (Battery Management System) monitors voltage, current, and temperature in real time, preventing overcharging, over-discharging, overcurrent, or overheating, and achieves individual cell balancing, improving battery safety and lifespan.
