Description

The BLACK DALY SMART BMS 40A 7-17S is a BMS board identified by its 7-17S series range and stated 40A current rating. It is intended for compatible lithium battery pack applications where the battery configuration and electrical requirements match the specifications of the selected model. Its black design and DALY identification help distinguish it when comparing BMS boards or checking replacement requirements.

Selecting the correct BMS is an important part of a lithium battery system. The number of cells connected in series, battery chemistry, current requirements, and electrical characteristics must be considered before choosing a board. This model is identified for a 7S to 17S range. The exact supported series configuration should be confirmed from the product label or official technical documentation before purchase. Do not assume that every configuration within the stated range has identical operating specifications.

The stated 40A rating is an important product identification detail. The exact operating conditions associated with this rating should be verified through the manufacturer’s datasheet. It should not automatically be treated as a continuous current rating without confirmation. Actual suitability depends on the battery cells, connected load, wiring, connectors, operating conditions, and complete system design.

Battery chemistry must also match the selected BMS. Different lithium battery chemistries have different voltage characteristics and charging requirements. The correct series configuration and charging parameters should be determined according to the battery cell manufacturer’s specifications. Before purchasing, confirm that the exact BLACK DALY SMART BMS 40A 7-17S version is suitable for the intended battery pack.

The Smart designation is included in the supplied product name. It does not by itself confirm the availability of Bluetooth, Wi-Fi, mobile application support, communication ports, display compatibility, or programmable functions. These features can vary between models and versions. If a particular monitoring or communication feature is required, check the exact model documentation before ordering.

This product is offered under the SUPERWAY brand through Superway. The DALY name is retained as part of the product identification, while SUPERWAY represents the brand under which the product is listed and sold. Customers should compare the model details and product label with their requirements before making a purchase.

For replacement applications, check the existing BMS board’s series configuration, current rating, battery chemistry, connector arrangement, and documented electrical specifications. Similar-looking BMS boards are not necessarily interchangeable. A difference in model version or terminal arrangement can affect compatibility, even when the series count and current rating appear similar.

Before installation, refer to the official manufacturer wiring diagram and model-specific instructions. Terminal identification and connector arrangements can differ between BMS models. Incorrect selection or installation can create electrical and fire hazards. Installation and testing should be carried out by a qualified battery technician using appropriate safety procedures.

The BLACK DALY SMART BMS 40A 7-17S is a model-specific option for compatible lithium battery pack applications. Confirming the exact series configuration, battery chemistry, current rating, and technical documentation before purchase helps ensure that the selected BMS matches the intended system requirements.
