Good and solid BMS having full protection. Assembled on hy2120type controllers. But there's a little Nooo. The scarf is stuffed exactly according to the recommended parameters from the datashite. And here there is no-the shutdown voltage (since the averaged characteristics are set in the datashite) will be at 3.575 volts-0,010. I. E. In this version, the 18650 series batteries will be undercharged. Therefore, according to the datashite, you need to play with resistors R1 and R2 in order to set the shutdown voltage of 4,1-4,2 volts. I. E. as a finished product, this scarf is not suitable. But in general, this is a very high-quality BMS-Ka defense set.
Therefore, if someone expects to just follow and get the perfect thing, it is definitely not worth taking. But if someone is ready to sit a little and customize, he will receive a quality controller.
