DALY BMS LFP 11S 20A

The DALY BMS LFP 11S 20A is a 11S 20A lithium iron phosphate (LiFePO4 / LFP) Battery Management System designed for 35.2V 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 11S LiFePO4 BMS is built around 11 cell groups connected in series, giving approximately 35.2V nominal pack voltage. The 20A 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 11S / 20A configuration that is easy to integrate into production packs, service replacements, prototype builds and OEM battery assemblies.

DALY hardware BMS products use dedicated cell-monitoring circuitry and MOSFET power switching across LiFePO4 battery platforms, a widely used architecture for EV, solar, inverter and backup-power battery packs. 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. The 11S 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 20A 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 DALY BMS LFP 11S 20A is intended for 11S LiFePO4 battery packs in the 20A product class. It can be integrated with cylindrical, pouch or prismatic cells when those cells are assembled into the corresponding 11-series battery architecture. The 35.2V nominal reference places the pack in the 36V-class market segment, making the product relevant to common searches for a 11S 20A LiFePO4 BMS, 36V-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

• 35.2V nominal LiFePO4 battery packs for 36V-class mobility and industrial applications

• Electric bicycles, utility vehicles and robotics battery systems

• Solar storage, UPS and backup-power battery modules

• AGV, automation and material-handling battery assemblies

• OEM and custom battery-pack production for medium-voltage DC systems

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.
