Description

The DALY BLACK 4-8S 40A SMART BMS is a smart battery management system designed for compatible battery pack configurations supporting between 4 and 8 series-connected cell groups. It has a specified current rating of 40A and features a black product design. This model is intended for battery applications where the required series configuration and electrical specifications match the product.

A Battery Management System (BMS) is an electronic component used in rechargeable battery packs. It manages battery operation according to the functions supported by its circuit design. A BMS works as part of the complete battery system alongside the battery cells, charger, wiring and connected equipment. Selecting the correct model requires checking the battery configuration and confirming that the BMS specifications are suitable for the intended application.

The 4S–8S designation indicates a supported series configuration range from four to eight cell groups. The actual series count must match the battery pack design and the voltage requirements of the connected equipment. Before selecting this model, confirm that the exact DALY BLACK version supports the intended series configuration and operating voltage range.

Battery chemistry compatibility is another important consideration. LiFePO4, NMC and other lithium battery chemistries have different voltage characteristics and charging requirements. The product title does not specify the supported chemistry, so consult the manufacturer’s technical documentation or supplier to confirm compatibility with the intended battery cells. Do not assume that this model supports every lithium battery chemistry.

This model has a specified current rating of 40A. Check the manufacturer’s documentation to establish the conditions under which this rating applies, including whether it refers to continuous discharge, peak current or another operating condition. Actual operating capability can depend on temperature, installation conditions, circuit design, cooling arrangements, wiring and connectors. The battery cells and other electrical components must also be appropriately rated for the intended application.

The SMART designation identifies this as a smart BMS model. However, the specific monitoring and communication capabilities of this product should be confirmed for the exact version. Features such as Bluetooth connectivity, mobile application monitoring, CAN, UART, RS485, display support and communication accessories should not be assumed to be included unless confirmed by the manufacturer or supplier.

Protection and monitoring functions can also vary between product versions. Details such as voltage monitoring, current monitoring, temperature monitoring, balancing functionality and protection thresholds should be verified using the technical documentation for the exact model. The product title alone does not confirm which functions are available or their operating specifications.

The BMS must be selected as part of the complete battery system. The charger should be suitable for the confirmed battery chemistry and series configuration. Charging voltage and current limits should follow the battery cell manufacturer’s recommendations. The BMS current rating should also be considered alongside the requirements of the connected equipment and the ratings of the battery cells, cables and connectors.

The DALY BLACK 4-8S 40A SMART BMS is offered under the SUPERWAY brand. DALY is the actual product brand, while SUPERWAY is the selling brand. The product is identified by its black design, 4S–8S series configuration range, specified 40A current rating and SMART BMS designation. Confirm the exact model revision and technical specifications before ordering.

Installation and integration should follow the manufacturer’s documentation for the exact model. Battery pack assembly and testing should be handled by someone familiar with lithium battery systems. Correct compatibility between the BMS, battery cells, charger and connected equipment is important for the intended battery application.
