Hi there!
This thread is the next step of this one, just so you know: https://diyjust-a-total-noob-willing-to-built-a-8s-from-amy-wan
I started with 8S for a 24V 280AH battery. This is paired with a 2000VA inverter and plugged through a MPPT 150/60.

About the BMS, Amy offered JBD BMS 8S 100A.

I built the box, did the cable management and so on. But now I'm stuck. Here is the data she shared with me

So she told me the 2 B- have to be attached together and therefore plugged to the total minus of the battery

But then, if I understood everything right as a total noob, the 2 C- have to be plugged with the Minus electrode of the MPPT. But I have just no idea on how to plug all these together. It's way too big for a tin solder (I tried...). So this is my main question here: how am I supposed to do this?! Did someone face the same problem already? Is the configuration good?

Sorry for that one, never been a great photographer.
Thanks in advance for your help fellow experts !
