Custom 4-Cell 5-Cell 6-Cell Series Battery Packs

Custom Battery Pack Solutions for Your Equipment

FOREWELL provides custom series-connected primary battery packs for electronic equipment requiring a specific output voltage, cell arrangement, connector or installation structure.

Available reference configurations include 4-cell, 5-cell and 6-cell battery packs. When 1.5V cells are connected in series, these configurations provide nominal outputs of 6.0V, 7.5V and 9.0V respectively.

Each battery pack can be customized according to the customer’s equipment specifications, installation space, electrical requirements and order quantity.

Reference Configurations

Configuration	Cell Connection	Reference Nominal Output
4-Cell Battery Pack	Four 1.5V cells connected in series	6.0V
5-Cell Battery Pack	Five 1.5V cells connected in series	7.5V
6-Cell Battery Pack	Six 1.5V cells connected in series	9.0V

The output values above are based on 1.5V primary cells connected in series. Actual specifications depend on the selected cell type and project requirements.

Typical Applications

Custom series-connected battery packs may be used in compatible equipment such as:

• Electronic measuring equipment

• Security and alarm devices

• Electronic toys

• Remote-control equipment

• Industrial control devices

• Portable electronic equipment

• LED and emergency lighting products

• Educational electronic equipment

• Specialized customer-designed equipment

The final application suitability must be evaluated according to the equipment’s voltage, current, installation space and operating conditions.

Battery Chemistry and Cell Selection

Available cell selection depends on the required voltage, operating current, runtime, dimensions and target cost.

FOREWELL can recommend a suitable battery solution based on the customer’s equipment specifications. Alkaline cells are generally suitable when improved runtime and discharge performance are required, while carbon zinc cells may be considered for cost-sensitive, low-drain applications.

The battery pack shown on this page is a configuration reference. Final cell type, capacity and performance specifications must be confirmed for each project.

Connector and Wire Customization

Different wire and connector configurations may be available according to customer requirements, including:

• Two-wire positive and negative output

• Customized wire length

• Customized wire color

• Different connector housings

• Connector polarity confirmation

• Stripped or terminated wire ends

• Customer-specified connector samples

Customers should provide a connector model, technical drawing, clear photograph or physical sample whenever possible.

Custom Development Process

1. Confirm the equipment requirements.

2. Select the appropriate battery model and number of cells.

3. Confirm voltage, dimensions, wiring and connector specifications.

4. Produce and evaluate a pre-production sample.

5. Confirm the sample and packaging requirements.

6. Begin mass production after final approval.
