HX-4S-F100A 4S 100A LiFePO4 BMS Protection Board with Balance

Product Description

Protect your compatible 4-cell LiFePO4 battery pack with the HX-4S-F100A Battery Management System (BMS).

Designed for 4S lithium iron phosphate battery assemblies, this protection board is advertised for a 12.8V nominal battery pack with a 14.4V charging profile. It provides battery protection and cell-balancing functionality for compatible battery pack projects.

The HX-4S-F100A model family is advertised with multiple MOSFETs, a heat-dissipation plate and protection against battery-related electrical faults. The dedicated LiFePO4 listing also describes an onboard wiring diagram to help identify connections.

This module is intended for compatible battery pack assembly, repair, DIY power systems and electronics projects. Correct chemistry, cell configuration, current rating and wiring must be confirmed before installation.

Key Features

• 4S LiFePO4 Configuration: Designed for compatible four-series lithium iron phosphate battery packs.

• 12.8V Nominal Pack: Based on four 3.2V nominal LiFePO4 cell groups.

• 14.4V Charging Profile Advertised: Confirm the appropriate charging voltage with the battery manufacturer.

• 100A Advertised BMS Rating: The HX model family is listed at 100A; verify the exact continuous current rating of this LiFePO4 version.

• Cell Balancing: Balance protection is advertised for the dedicated product.

• Multiple MOSFET Design: Generic HX-F100A listings describe 10 MOSFETs.

• Heat-Dissipation Plate: Aluminum heat-dissipation plate advertised on the HX model family.

• Battery Protection: Overcharge, over-discharge, overcurrent, short-circuit and temperature protection are advertised across HX-F100A listings.

• Wiring Reference: Dedicated product listing describes a printed wiring schematic.

• DIY Battery Projects: Suitable for compatible LiFePO4 battery pack assembly and repair.

Technical Specifications

Specifications are based on the dedicated LiFePO4 product listing and generic HX-4S-F100A model-family descriptions. Confirm the actual board's current rating, charging current, balancing performance, protection thresholds, dimensions and wiring before publishing.

Typical Applications

• 4S LiFePO4 battery pack assembly

• Compatible 12.8V battery systems

• DIY battery protection projects

• Battery pack repair and replacement

• Compatible portable power systems

• Solar energy storage battery projects

• Electronics and robotics battery applications

Installation & Safety

1. Confirm that your battery uses LiFePO4 cells and a 4S configuration.

2. Verify the actual BMS model and chemistry-specific charging profile.

3. Use four compatible cell groups with matching chemistry, capacity and condition.

4. Connect balance wires only according to the actual PCB labels and wiring diagram.

5. Confirm the continuous discharge current and charging current separately.

6. Use appropriate wire gauge, connectors, insulation and heat management.

7. Use a compatible LiFePO4 charger.

8. Do not use a standard 16.8V 4S Li-ion charging profile for a 4S LiFePO4 pack.

9. Do not assume generic HX-F100A protection thresholds apply to this exact LiFePO4 version.

10. Installation should be performed by someone familiar with lithium battery systems.

Important: This is a battery protection board, not a standalone charger. The advertised 100A rating does not guarantee that your cells, wiring, connectors or complete battery pack can safely deliver 100A continuously.

Package Includes

• 1 × HX-4S-F100A 4S LiFePO4 BMS Protection Board

Balance cable or wiring harness may be included depending on the supplied version. Battery cells, charger, enclosure and additional accessories are not included unless specifically stated.
