Description

The DALY Smart BMS LFP 4S 80A is a smart battery management system designed for 4S lithium iron phosphate (LiFePO4) battery pack configurations. It carries a specified current rating of 80A and is intended for battery packs containing four cell groups connected in series. This model is designed for applications that require a smart battery management board with an 80A specified current rating and a configuration suitable for 4S LiFePO4 battery packs.

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 specified 80A current rating is an important consideration when selecting this BMS. 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, cables, connectors, and other electrical components must also be suitable for the intended current requirements.

The smart BMS design is intended to support battery management functions according to the features provided by the exact model version. Communication and monitoring capabilities can differ between product variants. Features such as Bluetooth connectivity, mobile application monitoring, UART, CAN, RS485, or other communication interfaces should be verified from the product label and technical documentation before purchase. Do not assume that every smart BMS version includes the same communication options or accessories.

Protection functions can also vary depending on the circuit design and model version. Check the manufacturer’s documentation for details about overcharge protection, over-discharge protection, overcurrent protection, short-circuit protection, temperature monitoring, and balancing functionality. Protection thresholds and balancing specifications should be confirmed for the exact product rather than assumed.

Before installation, verify that the battery pack contains four series-connected LiFePO4 cell groups and that the BMS wiring arrangement matches the battery configuration. Check the terminal markings, polarity, connector pinout, and wiring diagram before making connections. The charging voltage and current must follow the battery cell manufacturer’s recommendations, and the charger must be suitable for a 4S LiFePO4 battery pack.

The DALY Smart BMS LFP 4S 80A may be considered for suitable 12.8V nominal LiFePO4 battery pack applications where its specified current rating and available functions meet the requirements. Use appropriately rated wires and connectors, maintain proper insulation, and ensure secure electrical connections. Battery pack assembly and testing should be carried out by someone familiar with lithium battery systems.

This product is offered under the SUPERWAY brand through Superway. Before ordering, confirm the exact DALY model version, 80A current rating, smart monitoring features, communication options, connector arrangement, and technical specifications. Selecting a BMS that matches the battery chemistry, series configuration, and electrical requirements is important for an appropriate battery management arrangement.
