JK BMS WIRING

[raffy323232]

good day to all. just bought the new jk bms. 16s 150amps with 2amps active balancer.
my question is... why there is 2 "B8" Terminals. which one should i use?
and is the first red wire from below will connect to main negative terminal?


thanks to all....

Here is a link to the description and wiring diagram found on the JK BMS website. Its a little blurry but looks like the B8 pin next to NT3 on the 3rd connector is not used. Just leave that particular red wire disconnected.

On mine both paths have the resistor in place so either could be used, other boards only have the resistor on the early path. Look above the 5th 8 pin chip in from the top left and you can see the unpopulated position for the 2nd R01 resistor, no other 8 pin chip is fed from 2 pins.

thanks!...i wonder whats the point of the manufacturer of this bms in creating this confusion on B8 terminal
i have another question... will my bms be destroyed if i connect the B8 on the leads without that resistor?

No, it will report a cell count issue and throw an alarm but no damage. Your JK reported total voltage will be short by the missing cell.

I took JK's image, sharpened it and added clarification which should be there by default.
