After more than a year using a hobby charger, I finally connected a BMS (BesTech HCX-223V1) to my 10S LiFePO4 pack.
I managed to get it wired without anything catching-fire/burning (shout out to @Namasaki for his helpful diagram) but noticed that when charging, the BMS draws 5A even though the power brick has a max rated output of 2A. Needless to say, the brick gets super hot after a few minutes.
According to the specs the BMS is capable of charging at a max of 20A, but I assumed that cos the power brick has a max output of 2A, then this would determine the upper charge rate?
Have I got something wrong? Were BesTech meant to set the BMS charge rate limit to 2A?
Any suggestions appreciated.
