Hi I just received a new bms and am not sure how to connect it. Specifically the b+ looks like there are numerous connection points do I just chose 1

B- seems clear- 2 holes bottom left corner
Then for the charger and load I presume I connect to the two holes on the c- side bottom right

Nb. Also attached my old bms

Battery plus goes directly to charger and load. You only connect B- (battery minus), C- (charger minus) and P- (power-load minus) to the board. BMS is getting plus from the balance wires. They should be chcecked twice and connected last.
 
Thanks Lubon. Sorry I missed your reply

When I connect them- on the board there are clear holes where to connect for the b- and c- but the p- doesn’t seem to have any holes

Do I just connect directly to the board anywhere in that p- section?

I have a similar bms and connected the c- and p- to the same spot. Be aware that when you tin the board most of the solder will flow down thru the perforations. Not a big deal but it makes a nice puddle of solder on the opposite side of the board.
