    Product Description

    [Multiple-string compatibility] 120A high-current lithium battery protection board
    3S/4S/5S/6S/7S/8S universal overcharge/over-discharge/short circuit/over-temperature full protection


    Features
    Multiple-string intelligent adaptation: 3S-8S battery packs are compatible with one key, no need to purchase repeatedly, saving costs.
    120A continuous high current: supports stable operation of high-power equipment such as power tools and energy storage systems.
    Seven-fold safety protection: overcharge, over-discharge, overcurrent, short circuit, overtemperature, balance, and reverse connection protection.
    Dynamic balancing technology: ±25mV battery cell voltage difference control, extending battery life by more than 20%.


    Application scenarios
    Electric vehicles/electric motorcycles: ensure stable power supply for high-power motors and no downtime when climbing.
    Outdoor energy storage system: solar energy storage, RV power supply safety management and control.
    Industrial equipment: long-term protection of AGV cars and drone battery packs.
    Household appliances: emergency power supply, household energy storage battery safety protection.


    Design advantages
    Military-grade MOS tube: using Infineon/TI chips, high temperature resistance of 130℃, stable and no board burnout.
    Intelligent sleep function: standby current <10μA, automatic power saving when idle.
    Minimalist wiring design: gold-plated interface anti-oxidation, support XT90/Anderson fast connector.
    Anti-interference shell: aluminum alloy heat dissipation + insulation coating, adapt to complex electromagnetic environment


    User pain point solution
    "Worried about incompatibility of different battery pack models?"
    → Adaptive 3S-8S, no need to replace the protection board, one board for multiple uses.
    "Severe heat generation under high current?"
    → Double-sided heat dissipation silicone + temperature protection, automatically cut off output at 85℃.
    "Poor balancing function leads to rapid battery attenuation?"
    → Dynamic balancing technology, voltage difference <0.03V, extending the cycle life of the battery cell.


    Installation Guide
    Three-step quick installation:
    Confirm the number of battery pack strings (such as 7S requires 7 wires)
    Connect B- (total negative pole) and P- (output negative pole)
    Connect the positive pole detection wires of each battery cell (B1-B8)
    Note: Reverse connection is strictly prohibited! Use a multimeter to verify the voltage before first use.


    Warranty and Service
    One-year warranty: Free replacement for non-human damage (including overcurrent burnout cases).
    Technical support: Provide wiring diagram customization and parameter debugging remote guidance.
    Accessory set: Optional silicone wire, heat shrink tube, and insulating gasket of the same style.

    Wiring precautions:
    1. Installing the protective board requires a certain amount of technical electronic knowledge.
    2. When wiring, first connect the B- wire at the soldering pad position to the total negative terminal of the battery (the B- wire should be soldered to a short and thick wire) and solder the wired terminal to the battery pack first, and then insert the protective plate.
    3. The connection between the battery terminal B- and the protection board terminal B- should be short and thick, otherwise it will cause the protection board to charge and discharge in advance and malfunction.

    4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
