A custom LiPo battery is a lithium polymer battery designed and manufactured according to specific application requirements, rather than using standard off-the-shelf battery models.
From my experience working with OEM customers, customization usually involves much more than size adjustment. It includes electrical performance, safety protection, mechanical structure, certification compliance, and long-term reliability.

Most customers come to us after encountering one or more of these issues:
| Common Problem | Root Cause |
|---|---|
| Battery doesn’t fit enclosure | Fixed pouch dimensions |
| Device shuts down unexpectedly | Incorrect discharge rate |
| Battery swelling | Incompatible charging design |
| Certification failure | Non-compliant cell materials |
A custom LiPo battery eliminates these risks before mass production, not after.

LiPo batteries use aluminum-laminated pouch cells, allowing flexible shapes such as:
This is critical for wearables, medical sensors, and compact IoT devices.

We design voltage and capacity based on real load profiles, not theoretical values.
| Parameter | Custom Range |
|---|---|
| Nominal Voltage | 3.7V / 7.4V / 11.1V |
| Capacity | 50mAh – 20,000mAh |
| Discharge Rate | 0.2C – 30C |
A custom PCM protects against overcharge, over-discharge, overcurrent, and short circuit. For medical or industrial devices, we often design dual-layer protection logic.
From concept to mass production, our OEM process includes:
This structured process dramatically reduces field failure risk.

Depending on target market:
| Market | Required Certifications |
|---|---|
| Global Shipping | UN38.3 |
| Consumer Electronics | IEC 62133 |
| Medical Devices | IEC 60601 |
| North America | UL 2054 |
| Europe | CE, RoHS, REACH |
Certification planning should start during battery design, not after.
| Feature | LiPo Battery | Cylindrical Li-ion |
|---|---|---|
| Shape Flexibility | ★★★★★ | ★ |
| Energy Density | High | Very High |
| Weight | Lighter | Heavier |
| Customization | Excellent | Limited |
| Typical Applications | Wearables, Medical | Power tools, EV |
From my professional perspective, you should evaluate:
The cheapest quote is often the most expensive mistake.
| Item | Typical Range |
|---|---|
| Sample MOQ | 5–20 pcs |
| Mass Production MOQ | 500–2000 pcs |
| Sample Lead Time | 7–15 days |
| Mass Production | 20–30 days |
Yes. We often start from mechanical constraints and reverse-design the battery.
Yes. We support startups and pilot projects.
Typically 2–4 weeks including samples.
Absolutely. Certification support is part of our OEM service.
