Hi guys,
I'm waiting for my VESC, enertion r-spec motor, and single mount kit to arrive (And 3 x ZIPPY 5000mah 3S 20C), so in the mean time I have started to read about BMS systems... I want to build my own laptop-style charging system!
Since I plan to have 9S Battery, I was wondering if I need to find or buy a custom 9S BMS, or using a bigger one (like 12S) and leaving 3 balance pins empty would work.
Secondly, when looking for a custom BMS, I've seen that they ask for the current of that BMS, and this is what I'm not really sure about.
My batteries can provide 5A * 20C = 100A continously (with higher peaks of 150A), but I'm sure that's not the current they are asking me for, since most of BMS I have seen are not above 40A. How much will be my motor demanding and how much should allow the BMS?
Could anyone show me and explain me a little bit (giving my setup) how to calculate the proper current they are asking me for? I really would appreciate, since I want to learn how to do it and understand a little bit more about the electronics behind it!
I will be posting every improvement of my BMS (if there is such a thing ) in this thread!
Thank you!
