3S BM15 14A Li-ion 18650 Battery Protection Board BMS 4MOS

The 3S 14A Li-ion 18650 Battery Protection Board (BMS) is a high-quality, reliable protection module designed for 3-cell lithium-ion battery packs. Labeled as HXYP-3S-CM02, this board features a robust 4-MOSFET design that ensures efficient power management and low heat generation. It provides comprehensive protection against overcharging, over-discharging, overcurrent, and short circuits, making it an essential component for maintaining the health and longevity of your custom battery packs.

This BMS is highly optimized for high-drain applications such as agricultural sprayers, 12V DIY power tools, solar LED streetlights, and portable electronics. It is fully compatible with standard 3.7V lithium-ion cells (like 18650 or 21700) and features dedicated solder pads for an external NTC thermistor to enable temperature-based safety cutoffs. With its compact form factor and clearly labeled connection terminals, it is easy to integrate into any maker or student project requiring a stable 11.1V to 12.6V power source.

Features:

• 4-MOSFET Design: Equipped with four high-performance MOSFETs for low internal resistance and superior current handling.
• Comprehensive Protection: Built-in safeguards against overcharge, over-discharge, overcurrent, and short circuits.
• NTC Temperature Interface: Features dedicated solder pads to connect an NTC thermistor for thermal protection.
• High Current Output: Supports a continuous discharge current of up to 14A, ideal for motor-driven applications like sprayers.
• Clear Labeling: Clearly marked solder pads (B+, B-, B1, B2, P+, P-) simplify the wiring and assembly process.
• Compact & Lightweight: Space-saving design that easily fits inside custom battery enclosures.
