What is Custom Battery?
A custom battery is a battery pack designed and built to meet specific requirements, such as size, voltage, capacity, shape, or connector type, that standard batteries cannot provide. It is tailored for a particular device or application to ensure the best performance and fit.
What Can be Customized
🔬Battery Chemistry
You can choose from multiple battery chemistries—including lithium-ion, LiFePO₄, sodium-ion, lithium-manganese, NiMH, and NiCd—to match your performance, safety, and cost requirements. Selecting the right chemistry ensures optimal cycle life, thermal stability, power output, and application-specific reliability.
Comparison for Different Battery Chemistry
| Chemistry | Environmental impact | Energy density (Wh/kg) | Safety | Nominal voltage (V/cell) | Cycle life (typical) | Charge temp (°C) | Discharge temp (°C) | Self-discharge (% / month) |
|---|---|---|---|---|---|---|---|---|
| Lithium ion (NMC) | Moderate | 150 ~ 260 | Moderate | 3.6 ~ 3.7 | 500 ~ 1000 | 0 ~ 45 | -20 ~ 60 | 1% |
| LiFePO₄ (LFP) | Better | 90 ~ 160 | High | 3.2 | 2000 ~ 6000 | 0 ~ 55 | -20 ~ 60 | 1% |
| Sodium-ion | Generally better | 90 ~ 160 | Good | 3.0 | 2000 – 4000 | 0 ~ 45 | -20 ~ 55 | 2% |
| Li-MnO2 | Good | 250 ~ 400 | Very safe | 3.0 | Disposable | N/A | -40 ~ 85 | 0.1% |
| NiMH | Moderate | 60 ~ 120 | Good | 1.2 | 1000 | 0 ~ 45 | -20 ~ 50 | 5 ~ 10% |
| NiCd | Lower (cadmium = toxic; stricter disposal rules) | 40 ~ 60 | Very robust (tolerant, wide temp range) | 1.2 | 1000 | 0 ~ 45 | -20 ~ 60 | 10 ~ 20% |
🔋Capacity
Battery capacity can be tailored to match the required runtime and energy demand of your device or application. Whether you need long-duration power or lightweight efficiency, custom mAh/Wh options ensure optimal performance and reliability.
⚡Voltage
Voltage levels can be configured by adjusting the number of cells in series, allowing the battery to meet the exact power requirements of your system. Custom voltage packs help improve tool efficiency, motor output, and compatibility with OEM designs.
🛡️BMS
A custom BMS allows you to define protection parameters such as overcharge, discharge cutoff, balancing type, and communication protocols. This ensures safer operation, longer cycle life, and seamless integration with smart devices or industrial equipment.
📐Size
Battery size can be redesigned to fit unique housings, compact enclosures, or space-restricted applications. Tailor-made dimensions optimize internal layout while maintaining stable output and high energy density.
🧰Hard Case / Housing
Hard cases can be customized for durability, waterproofing, impact resistance, and aesthetic branding. Custom housings protect internal cells and electronics, extending battery lifespan in demanding environments.
🔌Connectors
Battery connectors—including XT60, Deans, Anderson, Molex, EC5 and custom plug types—can be selected based on current rating and device compatibility. Proper connector matching ensures efficient power transfer and safer operation.
🏷️Labels & Packaging
Private-label branding, safety labels, and retail-ready packaging can be designed to align with your brand identity. Custom packaging enhances product professionalism and meets regulatory requirements for transport and global distribution.
How it works?
Requirement Consultation & Definition
At the beginning, we need to analyze your application’s power needs, including voltage, capacity, BMS functions, discharge rate, dimensions and safety standards. Clear requirement definition ensures the custom battery pack is engineered to match your performance, certification, and budget goals.
Design & Engineering
Our engineering team develops the battery architecture, selects the optimal cell chemistry, designs the BMS, housing, connectors, and protection features. This stage includes electrical modeling, thermal analysis, and structural engineering to guarantee reliability and compliance.
Sample & Testing
A prototype battery pack is manufactured based on the final design and undergoes performance testing, safety verification, and environmental simulations. Test data is analyzed to validate capacity, cycle life, thermal stability, and compatibility with your device.
Bulk Production & Quality Control
After sample approved, the battery enters in bulk production with strict QC procedures, including cell matching, automated assembly, and multi-stage inspection. Every pack is tested for voltage accuracy, internal resistance, BMS performance, and overall safety before shipment.
Delivery & After-Sales Support
The completed custom batteries are delivered with full documentation, including test reports, certifications, and user guidelines. Our team provides continuous technical support, warranty service, and engineering assistance to ensure long-term performance and reliability.
