Description

The XWS BMS LFP 4S 10A (6032) with Balancing Connector is a battery management system designed for 4S lithium iron phosphate (LiFePO4) battery pack configurations. It carries a specified current rating of 10A and is intended for battery packs containing four cell groups connected in series. The product includes balancing connections and a connector for battery wiring, making it suitable for battery assembly applications that require a 4S LiFePO4 management board.

A 4S LiFePO4 battery pack consists of four cell groups connected in series. With a nominal voltage of approximately 3.2V per cell group, the resulting battery pack has a nominal voltage of approximately 12.8V. The actual operating voltage and charging requirements depend on the battery cells and their manufacturer’s specifications. This BMS is intended for LiFePO4 chemistry and should not be used with NMC lithium-ion or other battery chemistries unless the manufacturer explicitly confirms suitability.

The balancing connections provide connection points for the individual series cell groups. They allow the BMS to perform the balancing-related functions supported by its circuit design. The supplied connector helps establish the required wiring connection between the battery pack and the board. Connector appearance alone does not confirm its pin arrangement, so the exact pinout and wiring diagram must be checked before installation.

The specified 10A current rating is an important consideration when selecting this board. The actual permitted operating current depends on the manufacturer’s specifications, circuit design, temperature, wiring, connectors, and installation conditions. Confirm the continuous and peak current limits before connecting a load or charger. The battery cells and other electrical components must also support the required current within their rated limits.

The XWS BMS LFP 4S 10A (6032) may be considered for suitable 12.8V nominal LiFePO4 battery pack projects where its electrical ratings and connection arrangement meet the application requirements. Before installation, verify that the battery pack has four series-connected LiFePO4 cell groups and that the balancing connector matches the board’s wiring specification. Correct battery chemistry, series configuration, polarity, and connector pinout are essential selection considerations.

Protection functions can vary between BMS models and circuit versions. Check the manufacturer’s documentation for details about overcharge protection, over-discharge protection, overcurrent protection, short-circuit protection, temperature monitoring, and balancing operation. The balancing method and current should also be confirmed from the exact product documentation rather than assumed.

The charging voltage and current must follow the battery cell manufacturer’s recommendations. The charger must be suitable for a 4S LiFePO4 battery pack. Use appropriate wires and connectors, maintain correct polarity, and insulate exposed electrical connections. Battery pack assembly and testing should be carried out by someone familiar with lithium battery systems.

The XWS BMS LFP 4S 10A (6032) with Balancing Connector is offered under the SUPERWAY brand through Superway. Before ordering, confirm the exact model number, 10A current rating, connector arrangement, and technical specifications for your intended battery pack. Selecting a BMS that matches the battery chemistry, series configuration, and electrical requirements helps ensure that the board is appropriate for the application.
