Let’s try and keep on topic here. If the OP wants, we can delete previous posts.


Seems a bit low to me?!


you could bypass output and use for charging/balancing


With 10S = 36V, 20A is still 1200 Watts of continuous power.


36 volts at 20 amps is 720 watts of continuous power.


You know that feeling when nothing goes right with your day :sweat:. I’m experiencing it right now.

Yes, 720 Watts.


Then i do not need such an expensive BMS. I could buy the 15€ BMS from ebay for charging…
This BMS here has also a soft switch which would be without use :smiley: :smiley:
