3S 11.1V 10A Battery Management System / BMS Module

3-Series (3S) Lithium Battery Management: Engineered specifically for 3-cell 18650 lithium-ion / LiPo battery setups operating at nominal 11.1V and max 12.6V charging voltage.

10A Continuous Discharge Output: Delivers up to 10A continuous discharge current (with instantaneous surge protection up to 20A), perfect for low-to-medium power DC electronics and small motor drivers.

Hardware-Level Automated Protection: Integrated monitoring IC provides instant protection cutoffs against overcharging, over-discharging, overcurrent, and short circuits.

Compact Strip PCB Form Factor: Space-saving linear board layout with clearly labeled solder pads (B-, B1, B2, B+, P-, P+) for easy fit inside narrow battery tubes or custom enclosures.

Low Idle Power Draw: Minimal static power consumption ensures that connected battery packs maintain their charge during extended standby periods.

Board Material: High-grade FR-4 glass epoxy printed circuit board equipped with surface-mount power MOSFETs and protection control IC.

Technical Specifications:

Series Configuration: 3S (3 Cells in series).

Nominal / Max Voltage: 11.1V nominal / 12.6V max charge voltage.

Continuous Discharge Current: Up to 10A.

Peak Surge Current: Up to 20A.

Board Color: Blue / Green PCB.

Usage Advice: Connect cell balance nodes (B1 and B2) accurately in sequence to ensure proper voltage monitoring across all three series cells.

Maintenance: Keep board clean, dry, and away from conductive metallic dust or debris to prevent inadvertent short circuits across terminal pads.

Essential 12V Compact Power Solution: Position as the ideal protection module for converting three 18650 cells into a protected 12V battery source for LED strips, small solar setups, and DIY 12V electronics.

Highlight Compact Safety: Emphasize how this lightweight module delivers essential safety features—preventing cell over-discharge and dangerous external shorts—without adding bulk to battery packs.

Recommended Cross-Sell Add-ons: Pair with 18650 BMS Board 3S 25A Balanced 12.6V, 3S 20A Li-ion Battery 18650 BMS Board 12.6V, 2S 10A 7.4V 18650 lithium battery protection board, and ESD antistatic mat 50x40CM PCB Welding Mat.
