TDT BMS LFP 4S 15AMP BLUE SQURE

TDT BMS LFP 4S 15AMP BLUE SQURE

The TDT BMS LFP 4S 15AMP BLUE SQURE is a 4S 15A lithium iron phosphate (LiFePO4 / LFP) Battery Management System designed for 12.8V nominal battery packs that need dedicated electrical protection. It combines cell-group voltage supervision with hardware power-path control to support dependable charging and discharging in backup power, e-mobility, energy-storage, robotics and custom battery-pack applications.

This 4S LiFePO4 BMS is built around 4 cell groups connected in series, giving approximately 12.8V nominal pack voltage. The 15A designation identifies the product current class and positions the board for battery systems with corresponding charge/discharge requirements. As a hardware BMS, the board sits directly in the battery protection path, monitors the series cell groups and controls the charge/discharge circuit when electrical limits are reached. The result is a clear 4S / 15A configuration that is easy to integrate into production packs, service replacements, prototype builds and OEM battery assemblies.

TDT hardware BMS boards are used as compact LiFePO4 protection modules for custom battery packs, mobility systems, robotics and energy-storage assemblies. Core protection functions include overcharge protection, over-discharge protection, overcurrent protection and short-circuit protection, helping the BMS supervise the cell stack and control the battery power path during abnormal electrical conditions. This version also features a compact blue-square PCB format, giving the product a clearly defined hardware configuration for battery-pack assembly. The 4S architecture supports cell-group voltage supervision across the complete series string, while the compact hardware format keeps the protection electronics close to the battery interconnects. This is especially useful in battery enclosures where efficient space use, short current paths, organized sense wiring and serviceable construction are important. For the 15A product class, the BMS forms part of the complete electrical protection system together with the battery cells, pack fuse, conductors, busbars or nickel interconnects, charger and connected load. The series-specific design makes the board a practical choice for professional battery assemblers who want a dedicated LiFePO4 protection board instead of a communication-heavy universal controller.

The TDT BMS LFP 4S 15AMP BLUE SQURE is intended for 4S LiFePO4 battery packs in the 15A product class. It can be integrated with cylindrical, pouch or prismatic cells when those cells are assembled into the corresponding 4-series battery architecture. The 12.8V nominal reference places the pack in the 12V/16V-class market segment, making the product relevant to common searches for a 4S 15A LiFePO4 BMS, 12V/16V-class lithium battery management system, hardware BMS and lithium battery protection board in India. Its defined series/current format supports new battery builds, replacement BMS projects, prototype packs and OEM assemblies while keeping the product identity straightforward for purchasing and production teams.

Applications

• 12.8V nominal LiFePO4 battery packs for backup power and portable energy systems

• Lead-acid replacement lithium batteries for UPS, inverter and utility applications

• Solar lighting, small off-grid storage and DC equipment battery packs

• Robotics, power tools and custom battery modules for OEM or service builds

• Custom battery-pack manufacturing, prototyping and replacement projects

Installation Guide

For professional battery-pack assembly, install the BMS according to the terminal markings and wiring diagram supplied for the board. Connect battery negative and the cell-sense points in sequence, then complete the pack-output and charging connections using the marked B-, P- and C- terminals or the common/two-port arrangement provided on the variant. Use appropriately sized conductors, nickel or busbar interconnects, secure insulation and a correctly rated pack fuse. After assembly, commission the battery with a compatible LiFePO4 charger and a controlled load so the complete pack can be observed under normal charge and discharge operation.
