hey guys! im having trouble with the bms. bms: http://www.batterysupports.com/44v-48v-504v-12s-80a-12x-36v-lithium-ion-lipolymer-battery-bms-p-392.html why is there no charge port? (-c). also, there are 2 wire coming out from both p- and b- and i dont know where they should go. please see my diagram and check for problems
Charge is P-
It’s explained in the schematic of the pagehttp://i1098.photobucket.com/albums/g378/lilianleung/LOGO%20Connecting%20Chart.jpg~original
Your schematic looks good, though I think you’re suppose to join one of the balance leads from each pack since its in series.
but in my diagram there is one wire that comes out from b- and is connected to nothing
Just unsolder it, or join it to B- for redundancy and bandwidth
what is the balance leads?
Well you should have 7 balance leads per lipo pack, not 6. 6 should go to each pack’s cell positive and one should go to cell negative. You’ll have to join the balance leads that represent the same S cell.
does this have 7 wires? https://hobbyking.com/en_us/graphene-6000mah-4s-65c-w-xt90.html
That has 5 since it’s 4s, you drew 6s on your schematic
thats a mistake… this is the battery https://hobbyking.com/en_us/graphene-6000mah-6s-65c-w-xt90.html
Yea that should have 7
so where do i connect the other 2 wires? the bms only have 12 of these
