2S 10A 7.4V 18650 lithium battery protection board

2-Series (2S) Lithium Battery Management: Engineered specifically for 2-cell 18650 lithium-ion / LiPo battery packs operating at nominal 7.4V and peak 8.4V charging voltage.

10A Continuous Discharge Capacity: Supports up to 10A continuous discharge current with up to 20A peak instantaneous surge protection, perfect for small motor drivers and portable electronics.

Automated Hardware Safety Protection: Built-in precision control ICs provide instant cut-off protection against overcharging, over-discharging, overcurrent, and output short circuits.

Low Quiescent Power Consumption: Designed with low static current draw, preserving long-term standby battery charge when connected pack devices are powered down.

Compact Low-Profile PCB Layout: Solder-friendly terminal design (B+, B-, BM, P+, P-) ensures easy assembly inside compact battery cases and custom project enclosures.

Board Material: High-grade FR-4 glass epoxy printed circuit board equipped with dual high-power MOSFETs and a dedicated protection IC.

Technical Specifications:

Series Configuration: 2S (2 Cells in series).

Nominal / Max Voltage: 7.4V nominal / 8.4V max charge voltage.

Continuous Discharge Current: Up to 10A.

Peak Surge Current: Up to 20A.

Board Color: Blue / Green PCB.

Usage Advice: Connect the center balance tap wire (BM) accurately between Cell 1 and Cell 2 to ensure both cells are monitored correctly.

Maintenance: Keep the board clean, dry, and protected from static discharge or loose metallic debris that could bridge solder pads.

Essential 2-Cell Power Pack Solution: Position as the ideal entry-level protection module for upgrading or building 7.4V rechargeable packs for RC cars, Bluetooth speakers, handheld meters, and LED lanterns.

Highlight Compact & Reliable Protection: Emphasize how this compact BMS board prevents battery cell destruction from over-discharge while protecting sensitive downstream microcontrollers from short circuits.

Recommended Cross-Sell Add-ons: Pair with 2S Li-ion 18650 7.4V 4A 2 series BMS Module, HX-2S-A2 Circular 2S 8.4V BMS 18650 Lithium Battery Protection Plate, 18650 BMS Board 3S 25A Balanced 12.6V, and ESD antistatic mat 50x40CM PCB Welding Mat.
