Key Considerations
When ordering a custom Li-Ion battery, it's crucial to consider several key aspects to guarantee the battery meets your unique needs and is safe for your intended application. Here are the essential factors:
Voltage (V)
Voltage is critical for battery power. Li-Ion cells deliver 3.6V-3.7V, and matching your pack's voltage to your device's needs ensures optimal performance.
Capacity (mAh)
Capacity indicates how much charge a battery can store. We can supply capacities ranging from 800mAh to 13500mAh based on how long you need your device to operate between charges.
Size & Form Factor
Battery dimensions and shape must match your device's space. Our custom batteries, built from 18650 to 21700 sized cells, are tailored for unique sizes and applications.
Configuration
Configuring batteries in series increases voltage, whereas parallel setups boost capacity. This flexibility allows for precise tailoring to meet specific power requirements.
Longevity & Cycle Life
Consider how many charge-discharge cycles the battery can endure before its capacity begins to significantly degrade, affecting its lifespan and replacement frequency.
Connector Type
Ensuring compatibility between your battery's connector and your device enhances efficiency and user-friendliness. Our range includes connectors from compact JR to high-power AS150, serving various needs.

Frequently Asked Questions
Li-Ion batteries are generally safe, but like any battery, they can pose a risk of fire or explosion if not used, stored, or handled properly. The risk can be minimized by following the manufacturer's instructions for use, storage, and charging, avoiding exposing the battery to extreme temperatures, and using a charger specifically designed for the battery.
The lifespan of a Li-Ion battery can vary depending on factors such as usage, temperature, and storage conditions. Generally, a Li-Ion battery can last between 2-3 years or 300-500 charge cycles before its capacity starts to degrade significantly. However, with proper care and maintenance, a Li-Ion battery can last longer.
To extend the lifespan of your Li-Ion battery, you can follow these tips:
-
Avoid exposing your battery to high temperatures, as this can damage the battery and reduce its lifespan.
-
Do not let the battery fully discharge, as this can also reduce its lifespan. It is recommended to charge the battery before it reaches 20% remaining charge.
-
Use a charger that is designed for your specific Li-Ion battery to avoid overcharging or undercharging.
-
Store your battery in a cool, dry place away from direct sunlight and extreme temperatures.
-
If you're not going to use your battery for an extended period, store it with a charge level of around 50%.
-
To safely store and transport a Li-Ion battery, you should:
-
Store the battery at room temperature (between 20-25°C), and avoid exposure to extreme temperatures or humidity.
-
Keep the battery away from flammable materials, direct sunlight, and water.
-
Transport the battery in a protective case or bag that can prevent physical damage or short-circuiting.
-
Avoid leaving the battery unattended while charging, and use a charger specifically designed for Li-Ion batteries.
-
Disconnect the battery from the device when not in use for extended periods of time.
-
If transporting multiple batteries, place them in separate protective cases to prevent any potential short-circuiting between them.
-
Li-ion batteries are charged using a charger that delivers a constant current to the battery until it reaches a specific voltage level. This is usually around 4.2 volts for most Li-Ion chemistries. Once the battery reaches this voltage level, the charger will switch to a constant voltage mode, where the voltage is held constant while the charging current gradually decreases. This is to prevent overcharging and potential damage to the battery.
It is important to use a charger specifically designed for Li-Ion batteries, as charging them improperly can lead to damage, reduced performance, or even a risk of fire or explosion. Li-Ion batteries should always be charged in a fireproof charging bag or container, and never left unattended during the charging process.
If a Li-Ion battery gets damaged, it should be handled with extreme caution as it can be dangerous. Do not use or charge the battery if it appears to be swollen, punctured, or shows any signs of damage. Place the battery in a fire-resistant container and dispose of it according to local regulations. It is important to handle damaged Li-Ion batteries carefully as they can potentially release hazardous chemicals, cause fires or explosions.
The best way to dispose of Li-Ion batteries is to recycle them properly. Many electronic stores and recycling centers accept Li-Ion batteries for recycling. It is important not to dispose of Li-Ion batteries with regular household waste, as they can pose a fire hazard and may leak harmful chemicals into the environment. Some cities have specific recycling programs for electronic waste, so it is recommended to check with local authorities for guidelines on proper disposal.
We also offer a battery takeback scheme as part of our battery recycling initiative with BatteryBack and WeeeCare.
