TDT BMS NMC 3S 15A WITH NICKEL AND BAL

TDT BMS NMC 3S 15A WITH NICKEL AND BAL

The TDT BMS NMC 3S 15A WITH NICKEL AND BAL is a 3S 15A 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 3S NMC BMS is designed around 3 cell groups connected in series. In a standard 3.7V nominal lithium-ion/NMC system, that represents approximately 11.1V nominal pack voltage. The 15A 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.

TDT protection boards are commonly used in compact lithium-ion battery packs where a simple hardware BMS is preferred over a communication-heavy smart BMS architecture. 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 balancing-equipped version adds cell-voltage equalization support, helping the cells in the series string remain closer in voltage during normal charging operation. Pre-attached nickel connections support fast integration with compatible cell interconnect layouts and simplify compact pack assembly.

The board's 3S 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 TDT BMS NMC 3S 15A WITH NICKEL AND BAL is intended for 3S NMC/lithium-ion battery packs in the 15A product class. It is suitable for cylindrical, pouch or prismatic lithium-ion cells when they are assembled into the corresponding 3-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

• 3S NMC battery packs for power tools and portable DC equipment

• Robotics, RC, automation and embedded lithium battery modules

• Portable backup power, lighting and field-service battery systems

• DIY and OEM lithium-ion battery packs using cylindrical or pouch cells

• Compact mobility, utility and electronics projects requiring protected battery output

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.
