Fixed two wires in wrong place JBD need to fix the wiring diagrams for uk and US market hard to read

two wires in wrong place JBD smart bms sensing 16s battery config i.e. 48v not 8s 24v frog star drift app work with this BMS

Start with both harnesses unplugged.

The black wire on the bigger harness goes to negative on cell one. Next, attach the rest of the wires on that connector to positive posts on cells in order. You should end with the red wire on positive of cell 13.

Now, the two red wires on the small harness goes to positive of cell 16, the next yellow goes to positive of cell 15, and the rest of the wires (including the other yellow, three whites, and a black) on the small harness all go to positive of cell 14.

Now plug in the big harness, then the small harness.
