Description

The XBL BMS LFP 2S 4A is a battery management system designed for 2S lithium iron phosphate (LiFePO4) battery pack configurations. It carries a specified current rating of 4A and is intended for battery packs containing two cell groups connected in series. This board is designed for applications that require a battery management system matched to a 2S LiFePO4 configuration.

A 2S LiFePO4 battery pack consists of two 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 6.4V. 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 confirms suitability.

The specified 4A current rating is an important factor 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 connected battery cells must also support the required current within their rated operating limits.

A battery management system helps manage the connected battery pack according to the functions provided by its circuit. Protection functions can vary between models and versions. Check the manufacturer’s documentation for details about overcharge protection, over-discharge protection, overcurrent protection, short-circuit protection, and balancing functionality. Do not assume that every protection function or a particular balancing method is included without confirmation for this exact model.

Before installation, verify the battery chemistry, series configuration, terminal markings, polarity, and wiring arrangement. The XBL BMS LFP 2S 4A must be used with a suitable 2S LiFePO4 battery pack. Do not connect it to a battery pack with a different number of series-connected cell groups. Correct wiring is essential, and the product documentation should always be followed when connecting the board.

The charging voltage and current must follow the battery cell manufacturer’s recommendations. The charger must be suitable for a 2S LiFePO4 battery pack. Battery cells, wires, connectors, and other components should all be selected according to the electrical requirements of the application. Proper insulation and secure electrical connections are also important during battery pack assembly.

The product carries the supplied classification code 85079090. This code is included for product identification and classification reference; buyers should confirm the applicable customs or tax classification requirements independently when needed.

The XBL BMS LFP 2S 4A is offered under the SUPERWAY brand through Superway. Before ordering, confirm the exact model, 4A current rating, wiring 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.
