DALY BMS NMC 16S 40A RED WP

The DALY BMS NMC 16S 40A RED WP is a 16S 40A NMC lithium-ion Battery Management System designed for battery packs that need compact, dedicated electrical protection. It combines cell-voltage supervision with power-path control to support safer charging and discharging while keeping the protection hardware practical for EV, energy-storage, robotics and custom battery-pack integration.

This 16S NMC BMS is designed around 16 cell groups connected in series. In a standard 3.7V nominal lithium-ion/NMC system, that represents approximately 59.2V nominal pack voltage. The 40A designation identifies the product's current class, making it easy to select the appropriate protection-board family for the intended battery build. As a hardware BMS, the board sits directly in the battery's protection path and manages the charge/discharge circuit when electrical limits are reached.

DALY hardware BMS products are widely used as compact lithium battery protection boards for mobility, backup and energy-storage packs, with dedicated MOSFET switching for charge/discharge protection. Core BMS protection functions include overcharge protection, over-discharge protection, overcurrent protection and short-circuit protection. These functions help prevent the cell stack from operating outside its intended electrical window and provide an additional protection layer between the battery cells, charger and connected load. The RED WP configuration uses a protective red waterproof-style enclosure/encapsulation, making it a practical option where the BMS needs additional physical shielding inside the battery enclosure.

The board's 16S architecture also supports cell-group voltage monitoring across the series string. Its compact PCB format is suited to battery enclosures where efficient space utilization, short interconnect paths and serviceable wiring are important. The result is a practical NMC battery protection board for assemblers who need a model-specific, current-specific hardware BMS rather than a universal smart controller.

The DALY BMS NMC 16S 40A RED WP is intended for 16S NMC/lithium-ion battery packs in the 40A product class. It is suitable for cylindrical, pouch or prismatic lithium-ion cells when they are assembled into the corresponding 16-series configuration. The product works with a chemistry-correct lithium-ion charging system and integrates with standard battery-pack wiring, fusing and high-current interconnects. Its series-specific format makes it a strong choice for new battery builds, replacement BMS projects, prototype packs and OEM battery assemblies.

Applications

• 16S NMC battery packs for electric mobility and traction applications

• E-bike, e-scooter and light-EV battery assemblies using NMC/Li-ion cells

• Industrial backup power, telecom and DC energy modules

• Solar and distributed energy-storage battery packs

• OEM battery systems for robotics, automation and commercial equipment

Installation Guide

For professional battery-pack assembly, install the BMS using the terminal labels and wiring diagram supplied for the board. Connect the battery negative and cell-sense points in sequence, then complete the pack output and charging connections according to the marked B-, P- and C- terminals where present. Use appropriately sized conductors, nickel or bus connections, secure insulation and a correctly rated fuse. After assembly, commission the battery with a compatible NMC/lithium-ion charger and a controlled load so the complete pack can be checked under normal operating conditions.
