Confirm 10s BMS diagram

Can someone please confirm this diagram is 100% ok?

I have two concerns:

  1. Does it matter where the Fuse is located (does it need to be on the other side (BMS side)) of the charge port or is as per diagram correct.

  2. Are the balance wires correct or should I be keeping the negative wire on battery five (5) rather then battery one (1) ?

If your charger is connected to c-, the other pin needs to go to b+.
Balance leads look good but I’d recommend drawing out each cell for clarity when you’re working.
Also your polarity for vesc and volt meter are backwards.

Thanks for the response man, few additional questions off the back of that.

This is the BMS there is no where to connect to B+ but an obvious spot to connect B-

Also with the volt meter I’m a bit confused as to how that’s incorrect

Also the balance cables coming off the battery are red white and black so how could I possibly go wrong if I just don’t use black on all cells except cell 1? Genuinely interested in what can go wrong there.

Sorry, by b+ I meant the battery positive.
The main red wire in your diagram is actually connected to battery negative so all the components on it are flipped.

According to his diagram all balance leads are flipped.
@Customesk8 Do you have a BMS datasheet?

@Jordicious Oh haha yeah I see what your saying, without opening the board to see the actual batteries I just happened to put positive on the diagram first but understand that is wrong.

It is wired up and working but trying to add the BMS and just want to be 100% sure of it before going ahead.

@Mainflow unfortunately no, I got i t from ebay last year and checked back today on the listing as well as similar ones to find a data sheet but it just has pictures in the listing no actual information. It does have B0-B10 as per the diagram above.

So are you saying it should be RED/YELLOW not YELLOW/RED

1- doesn’t matter

2- your balance wires are reversed

My mouse was over the reply button(I had a similar answer), as you have send your answer. :joy:

Ok i think i see what you are saying so is this diagram 100% correct IF I had the NEGATIVE on the left and POSITIVE on the right. :joy: :wink:

Have a look in here

and in here

No, that one is not correct either

As @b264 said, your balance leads are flipped.

Yes

It’s not correct at all, right now. Don’t jump to conclusions.

Also, there is no “correct” way to wire an esk8, but there are many, many “incorrect” ways which cause certain fires or failures

It’s almost there, just need to keep the charge port positive on the battery positive.
Then I think it would be correct.

Ok so I’m doing charge only.

I based my diagram off this but just did it myself to fully understand what I’ll be doing struggling to see the difference between mine and this one. minus a slightly different configuration

Your balance leads are flipped, see how B10 goes to battery negative on yours but battery positive on the diagram above?

I think I am confusing myself + everyone else by having the POS and NEG switched.

How does this look?

That one WILL work. If you want to have a lights circuit on P- though, you will need to move the loop key to the positive wire. But without that, it looks great as-is

Thank you all so much for your help, I think I knew I had it right but I was drawing it wrong and asking the wrong thing haha.
