3S 11.1V 40A Lithium Battery Management System (BMS) with Protection Circuit

The 3S 40A Lithium Battery Management System (BMS) is designed for 3-series lithium-ion battery packs with a nominal voltage of 11.1V. It ensures efficient battery performance by supporting up to 40A of continuous discharge current and protecting against overcharge, over-discharge, overcurrent, and short circuits. This BMS is perfect for high-power applications like electric vehicles, power tools, and DIY projects.

Key Features:

• Voltage Management: Handles 3S lithium-ion battery packs with a nominal voltage of 11.1V and a charge voltage of 12.6V.
• Overcharge Protection: Stops charging at 4.25V ± 0.05V per cell to prevent damage.
• Over-Discharge Protection: Disconnects load at 2.5V ± 0.05V per cell for battery safety.
• Current Handling: Allows 40A continuous and 50A peak discharge currents.
• Comprehensive Safety: Integrated overcharge, over-discharge, overcurrent, and short-circuit protection.
• Durable PCB Design: Built for high-power applications with efficient thermal management.
• Compact and Lightweight: Ideal for portable energy systems and DIY battery packs.
• Easy Installation: Clearly labeled solder points for hassle-free assembly.

Package Includes: 1 x 3S 11.1V 40A Lithium BMS with Protection Circuit
