Lithium Battery Protection Board 3S PCB 11.1V 12V 12.6V with Recovery Maximum Transition Current 10A-13A

3-Series (3S) Lithium Protection: Tailored for 3-cell 18650 lithium-ion / LiPo battery setups operating at nominal 11.1V, 12V, and peak 12.6V charging voltage.

10A–13A Maximum Transition Current: Handles continuous discharge current up to 10A with instantaneous peak surge handling up to 13A for small-to-medium power DC loads.

Automatic Recovery Function: Built-in auto-recovery logic automatically restores power output once fault conditions (such as short circuits or temporary overloads) are removed.

Comprehensive Safety Protection: Features hardware-level cutoffs against overcharging, over-discharging, overcurrent, and output short circuits to protect cell health.

Compact Strip PCB Layout: Space-saving linear form factor with clearly labeled solder pads (B-, B1, B2, B+, P-, P+) for clean, reliable wiring in narrow battery tubes or enclosures.

Board Material: High-grade FR-4 glass epoxy PCB (blue) equipped with dual surface-mount power MOSFETs and protection control IC.

Technical Specifications:

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

Nominal / Max Voltage: 11.1V–12V nominal / 12.6V max charge voltage.

Continuous Discharge Current: 10A.

Max Transition Current: 13A peak.

Board Color: Blue PCB.

Usage Advice: Connect all balance leads (B1 and B2) in exact sequence between cells to ensure accurate multi-cell monitoring.

Maintenance: Keep board clean, dry, and stored in anti-static packaging when not in use to avoid static damage.

Essential 12V Auto-Recovery Module: Position as a reliable protection board for converting three 18650 cells into a protected 12V power supply for LED strips, small DC motors, and portable electronics.

Highlight Self-Healing Auto-Recovery: Emphasize how the automatic recovery feature eliminates manual board resetting after temporary overcurrent faults, ensuring hassle-free operation.
