    Very good product at this price (160₹)
    Model no. is HX_3S_FL25A-A,comes with DW01A charge controller IC,8 Mosfets(4 are of 50A and 4 are of 80A) and 100 ohms balance circuit which is decent
    If there where 43,47 or 68 ohms resistors where used the balancing would have been much faster,(Note:-Always buy BMS with balance circuit for longer life of your battery pack) overall it’s a good product, for small projects like 10 amps,if you want more than that you should consider buying robu’s primium orange BMS above 40A
