Custom Lithium Battery Pack Manufacturer

ASOL is a custom lithium battery pack manufacturer in Shenzhen, building made-to-order Li-ion, LiFePO4 and lithium-polymer packs for device makers, integrators and brands. If an off-the-shelf battery doesn't fit your product, we engineer one that does — to your exact voltage, capacity, shape, BMS and connector.

1. When You Need a Custom Battery Pack

Standard batteries rarely match a real product: the voltage is wrong, the footprint won't fit, the discharge rate is too low or the connector is non-standard. A custom pack solves all of these in one engineered assembly — sized to your enclosure, matched to your load profile and protected by the right BMS.

2. Chemistries & Configurations We Build

• 🔋 Li-ion (18650 / 21700) — high energy density for power tools, e-mobility and instruments
• 🔋 LiFePO4 — long cycle life and safety for deep-cycle, RV, solar and industrial use
• 🔋 Lithium polymer (LiPo) — thin, light, custom shapes for wearables, IoT and medical devices

Series and parallel configurations from 3.7V single cells up to 48V+ packs, with capacity tailored to your runtime target.

3. Our OEM/ODM Pack Design Process

Send us the application, target voltage, capacity, dimensions and discharge requirement. Our engineers recommend the cell and configuration, design the BMS and mechanicals, build and test samples, then move to validated production — all under your brand.

4. Custom BMS & Connector Options

• 🛡️ Protection: over-charge, over-discharge, over-current, short-circuit, temperature
• ⚖️ Active cell balancing for longer pack life
• 📡 Smart options: Bluetooth, RS485/CAN communication, SOC gauge
• 🔌 Any connector & wire length — JST, Molex, XT, Anderson, bare leads and more

5. Industries & Devices We Power

Our packs run in medical equipment, POS and handheld terminals, robotics and AGVs, e-bikes and scooters, drones, security and IoT devices, and energy storage. Explore our lithium polymer, cylindrical and special battery pack ranges for reference designs.

6. Quality, Testing & Certifications

Cells are graded and matched, packs are aged and load-tested, and shipments are certified to UN38.3 with CE and RoHS compliance. Full test reports and, where required, UL documentation are available.

Frequently Asked Questions

Can ASOL build a battery pack to my exact dimensions and voltage?

Yes. As a custom battery pack manufacturer, ASOL builds to your specified voltage, capacity, footprint, discharge rate, BMS and connector — for Li-ion, LiFePO4 or lithium-polymer chemistries.

Which battery chemistry should I choose?

It depends on your priorities: Li-ion for maximum energy density, LiFePO4 for cycle life and safety, and lithium polymer for thin, light or odd-shaped designs. Our engineers will recommend the best fit for your device.

Do you provide engineering support for device integration?

Yes. We help select the cell and configuration, design the BMS, choose connectors and validate samples so the pack drops cleanly into your product.

What certifications do your packs carry?

Packs ship certified to UN38.3 with CE and RoHS compliance; UL and other certifications are available depending on the model and target market.

What is the MOQ and lead time for a custom pack?

MOQ and lead time depend on the design and volume. Samples are provided before bulk production — contact us with your spec for exact figures.
