Okay, so i did order some stuffs and my order arrived strange.

I got doublettes of some things i did order but this bms i ordered was not, i got 2 different ones.

I ordered a 3S 20A bms and i got this.

Easy to identify as a 3S bms, everything makes sense and nice text on the posterior side., B1 B2 and B+

and then i got this.

What is that kind of bms? I can see B1,2,3 and B+. is it a 4S bms? or what is that. i can see (from what i guess) a placement for a temperature sensor as well, if that is what T1 stands for
