I have a question, “anti-spark switch” for me means this:
Is this necessary? Consider that:
Maybe I should not use a cable from the JST battery? But which of them? …
The Lipo has only 6 cells but there are 7 balance wires. What would you guess the extra wire is for?
To consider each cell’s voltage as one ( the sum ) ?
I know that each lead of balance cable is connected to:
- main leads ( + , - )
- middle link betwheen cells
So for example: 6 cells make 7 cable , 5 in the middle and 2 main leads.
Right?
The 6 color wires go to the pos side of each cell. The red wire on the edge of the connector is always the last cell in series. In this case its cell 6. The black wire on the opposite edge is always a ground wire. You omit the black ground wire when connecting to a Bestech or Battery Supports bms.

But after this mod I’ll not be able to charge the battery with my Imax B because of soldering leads of balance cable??
Correct. However i used a balance lead extension and soldered those to the wires from the BMS lead. Then just plugged the battery’s lead into that.
That way i could still balance them if I ever wanted to. However I never have. But it still makes it easier to replace a battery if ever needed.

I’m with @SageTX That is the solution that I used on my builds and in my opinion, it’s the best solution.
No, this was a digram using the BMS for charging as well.
I like this solution, thank you very much! So I have to create a balance lead extension without the black wire ( ground ) in order to connect the JST-HX ( 7 wire - 7 pin ) from my battery to the new balance lead ( 6 wire - 7 pin ) of the BMS, all right? Are these good?? : http://amzn.to/2qvRdat
@Namasaki Can you answer to this question please? https://www.electric-skateboard.builders/t/is-it-possibile-to-charge-an-e-skate-directly-to-the-home-socket/23904/61?u=edoardo
Yes, search BMS on the forum. If you add a bms to your board youll be able to charge from a wall socket. Its basically putting your imax charger inside the board 
Sorry but I did not understand how you implemented these parts:
XT60 has to pin ho how do you connect three of this in that way?
It is a parallel connector or splitter like this one I made. All it does is turn one XT60 into 2 XT60s.
You can also find them online for cheap, tho these have wires and are backwards (male where female should be and vice versa). I recommend making your own which is easier, smaller, and cheaper. https://www.amazon.com/Dimart-Parallel-Connector-Extension-Splitter/dp/B01ALERNYA/ref=sr_1_5?s=toys-and-games&ie=UTF8&qid=1495975600&sr=1-5&keywords=XT60+parallel+y+cable
The second place you circled I simply soldered the voltage meter onto the XT60 along with the main power leads.

Now it’s clear. Thanks!
My voltage meter has JST-HX connector ( is used with my LiPo battery ), I have to buy another one with red/black wires?
Yes you should, those lipo checkers usually drain power from one cell which leads to uneven cells.
Could you suggest one of these from AliExpress?
Yes. That’s a plan. And yes those are fine.
Sorry but I meant to suggest a voltmeter ( 2 wire ) from AliExpress with a right voltage range and precision.
This charger ( https://goo.gl/kFJwtD ) will work fine with this BMS ( https://goo.gl/1kpBcP ) ?
And 4A is a reasonable way to charge a 4500mAh 22.2V 6s1p LiPo battery?
