This is the one with best quality, waterproof BMS board for you to assemble your ebike battery using 18650 or 21700 cells. Every BMS is carefully checked to pass quality control. 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 100A, with short protection, over charging and over load protection, and balance charging/discharging functions. Assembled battery can be used for a motor up to 1000W. Can check our pictures for more specifications. The board's dimension is 2.38*2.85*0.38 inches. You will get a 10S BMS and the balancing wires. 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. The second picture of our ebay list shows a wiring diagram. Please strictly follow these instructions, because any change of setting can permanently damage it!
