Custom Lithium Battery Pack Manufacturer

ASOL provides custom lithium battery pack solutions for OEM, ODM and equipment manufacturing projects. Available solutions include 18650 and 21700 lithium-ion battery packs, lithium polymer cells and packs, and finished LiFePO4 batteries and battery systems for supported applications.

Battery configuration can be evaluated according to the required voltage, capacity, continuous and peak current, installation space, PCM or BMS, communication, wires, connectors and operating environment. Final specifications depend on technical feasibility, available cell or battery options and confirmed project requirements.

ASOL does not supply loose or individual LiFePO4 cells.

1. When a Custom Battery Pack Is Required

A custom battery pack may be required when an available standard battery does not match the equipment’s voltage, capacity, current, dimensions, connector, communication or installation requirements.

A suitable solution must be evaluated as a complete electrical and mechanical assembly. Cell selection, series and parallel configuration, protection design, charging compatibility, wiring, connector, installation space and operating conditions all affect the final battery specification.

Customization does not mean that every requested size, shape or configuration is technically feasible. Final specifications must be confirmed after project review.

2. Battery Technologies and Solutions

18650 and 21700 Lithium-Ion Battery Packs

ASOL supplies 18650 and 21700 lithium-ion cells and evaluates custom cylindrical battery packs for suitable equipment projects. Cell model, series and parallel configuration, discharge current, PCM or BMS, wiring, connector and enclosure requirements must be confirmed according to the application.

Lithium Polymer Cells and Battery Packs

ASOL supplies lithium polymer pouch cells and can evaluate protected single-cell assemblies and multi-cell battery packs. Available dimensions, capacity, PCM, NTC, wires, connectors and battery configuration depend on the selected cell and technical feasibility.

Finished LiFePO4 Battery Solutions

ASOL provides finished LiFePO4 batteries and battery systems for RV, lead-acid replacement, residential and light-commercial solar backup, and commercial or industrial energy storage projects. Available voltage, capacity, BMS, communication, enclosure and system compatibility depend on the selected product and project requirements.

ASOL does not supply loose or individual LiFePO4 cells.

3. Information Required for Battery Evaluation

To evaluate a battery project, please provide as much of the following information as possible:

  • Application and equipment type
  • Required nominal voltage
  • Required capacity or operating runtime
  • Continuous and peak discharge current
  • Charging voltage and charging method
  • Maximum permitted dimensions, including tolerances
  • Installation method and available space
  • PCM or BMS protection requirements
  • Communication requirements, if applicable
  • Wire length, wire gauge and connector model
  • Operating and charging temperature
  • Required certifications or destination-market requirements
  • Estimated order quantity
  • Delivery destination

If available, customers may also provide the equipment specification, battery drawing, connector drawing, load profile or existing battery specification for review.

4. PCM, BMS, Wiring and Communication Options

Protection and control requirements depend on the battery chemistry, voltage, current, cell configuration and application. ASOL can evaluate suitable PCM or BMS options and related components according to the confirmed project requirements.

Depending on the project, the evaluation may include:

  • Overcharge and over-discharge protection
  • Overcurrent and short-circuit protection
  • Temperature monitoring
  • Cell balancing requirements
  • NTC or other temperature-sensing requirements
  • CAN or RS485 communication
  • Bluetooth or state-of-charge monitoring
  • Wire length and wire gauge
  • Connector selection
  • Fuse and insulation requirements

These functions are not standard on every battery pack. Availability must be confirmed for the specific configuration.

5. OEM/ODM Project Process

A custom battery project normally follows these stages:

  1. Application and requirement review
  2. Cell or existing battery option evaluation
  3. Preliminary electrical and mechanical configuration
  4. PCM or BMS and component matching
  5. Preliminary specification and quotation
  6. Sample feasibility and arrangement, when applicable
  7. Customer testing and specification confirmation
  8. Production and final inspection

Sample availability depends on the battery category and project feasibility. Samples may be evaluated for cylindrical lithium-ion and lithium polymer projects. Samples are not available for RV batteries, lead-acid replacement batteries, wall-mounted ESS products or high-voltage ESS products.

Sample specifications, cost and lead time are confirmed separately, and sample freight is paid by the customer.

6. Applications

ASOL evaluates battery solutions for applications such as:

The suitability of a battery technology and configuration must be evaluated according to the actual equipment and operating requirements.

7. Quality, Testing and Documentation

Quality checks and documentation requirements depend on the selected battery, configuration, order and destination market. Project-specific checks may include cell or component verification, dimensional inspection, voltage and internal-resistance checks, capacity testing, PCM or BMS function checks, protection testing and final battery inspection, as applicable.

Available certifications, transport test reports and compliance documents must be confirmed for the specific battery configuration and destination before ordering. Do not assume that every product carries the same certification set.

8. Frequently Asked Questions

What types of custom lithium battery packs does ASOL provide?

ASOL can evaluate 18650 and 21700 lithium-ion battery packs, lithium polymer cells and battery packs, and finished LiFePO4 battery solutions for supported OEM, equipment and energy storage applications.

Does ASOL supply loose LiFePO4 cells?

No. ASOL does not supply loose or individual LiFePO4 cells. We provide finished LiFePO4 batteries, battery packs and battery systems for supported applications.

Can ASOL manufacture a battery to any size or shape?

No size or shape should be assumed to be feasible without evaluation. ASOL reviews the required dimensions, electrical specifications, available cells, protection components and manufacturing requirements before confirming a battery configuration.

What information is required to evaluate a custom battery pack?

Please provide the application, voltage, capacity or runtime, continuous and peak current, charging method, maximum dimensions, PCM or BMS requirements, communication, wires, connector, operating temperature, quantity and destination.

Does every custom battery pack include a BMS?

The required protection solution depends on the battery chemistry, voltage, current and configuration. A suitable PCM or BMS can be evaluated according to the project requirements, but functions and communication options vary by configuration.

Are samples available for custom battery projects?

Samples may be evaluated for cylindrical lithium-ion and lithium polymer projects according to the specifications, quantity and project feasibility. Samples are not available for RV batteries, lead-acid replacement batteries, wall-mounted ESS products or high-voltage ESS products. Sample cost, lead time and freight are confirmed separately.

What certifications are available?

Available certifications, transport test reports and compliance documents depend on the selected battery, configuration and destination market. Applicable requirements must be confirmed before ordering.
