    Description

    This is the BMS with best quality, and waterproof for you to assemble your ebike scooter battery using 18650 cells.
    It can be used as 14S for a 52V battery, or 13S for a 48V battery by leaving the last red balancing wire disconnected. Both 52V and 48V batteries are called "48V type", which is why "48V BMS" is printed on it.
    You can use many branded cells such as Tesla, LG, SAMSUNG, Panasonic, FST, etc. But please make sure that your cells are with good quality and similar capacity/voltage before assembling.
    Its discharging current is continuous 30A and peak 150A, with short protection, over charging and over load protection, and balance charging/discharging functions.
    Assembled battery can be used for motor up to 1500W. Can check our pictures for more specifications (picture 2 has a diagram for wiring).
    The board's dimension is 2.38*2.85*0.38 inches.
    Instructions for assembling
    : First, make your cells (
    similar capacity/voltage
    ) in parallel and series. Second, solider the B- wire of this BMS to battery negative, together with the black balancing wire. Third, add red balancing wires to each positive of your parallel cells sequentially, one at a time, until the last red balancing wire goes to the battery positive. Fourth, add a wire to battery positive as charging/discharging positive. Last, the charging/discharging negative is from the P- of your BMS.
