LIPO Charge only Smart BMS wiring Guide

:joy: No. You have 6 balance wires so you need to go

p
n1
n2
n3
n4
n5

Also, label the batteries right to left.

And put the balance wires under the label with the red balance wire on each battery facing right.

Oh shit :joy: my fault, hold up

Can’t get the stupid balance wires to stay put but I got it where the red balance wire is on the right

Go get some tape. And also get a sharpie and label the batteries permanently.

We need a reference photo where everything is clearly labelled. Otherwise, you won’t understand what I m saying.

Made it easier to see since I live in a cave lmao

:angry: Label them right to left. It should go 2,1 NOT 1,2

Swap the batteries around.

Luckily their dry erase markers so easy wipe and I can start over :upside_down_face:

Or just move the batteries around . LMAO

Too much work :joy::joy:

Ok perfect.

series harness

main positive lead on battery 1 goes straight to the vesc
main negative lead on battery 1 goes to main positive on battery 2
main negative lead on battery 2 goes to the vesc

BMS wires

P on battery 1 goes to the red wire on the BMS harness
N1 on battery 1 goes to the next wire up from the red wire on the BMS harness
N2 on battery 1 goes to next wire up on the BMS harness
N3 on battery 1 goes to next wire up on the BMS harness
N4 on battery 1 goes to next wire up on the BMS harness

N5 on battery 1 doesn’t go anywhere. Skip it.

P on battery 2 goes to next wire up on the BMS harness
N1 on battery 2 goes to next wire up on the BMS harness
N2 on battery 2 goes to next wire up on the BMS harness
N3 on battery 2 goes to next wire up on the BMS harness
N4 on battery 2 goes to next wire up on the BMS harness
N5 on battery 2 will go the last wire on the BMS harness which should be the black wire.

Make sure you disconnect the BMS harness from the BMS while you work on this.

Wym wire goes up, it goes to the BMS?

???

What you mean by this

The white wire right next to the red wire. N2 would go to the second white wire next to the red wire and so on.

That will plug into the battery extenders or would I have to solder it

into the balance wire extenders which you will solder to the correct BMS harness wires. Cut the connectors I circled in green. You wont need them. And connect the bare wires to the BMS harness in the order I mentioned. You will need to solder them.

So Battery 1, those red white and white wires go into the first extender and battery 2 all whites go in the second extender

huh? There is no white wires on the batteries.

I meant the BMS harness
