Hello everyone,

I’ve got parts for a first build on the way (2*3s 4000mAh in series, VESC, 236kv Turnigy SK3, self-built mount) but wanted some input on my wiring setup. I’ve got a rough diagram below that I’d be happy to refine on demand, but the goal is to be able to charge both 3S packs without removing them from the board.

Novice Electrician Questions. Have been resolved

With the loop key removed, I should be able to plug in the XT60 connector as shown in the diagram (Labeled with a 2) from the charger, along with the balance lead using this harness:

The 3S lead with the black wire on that harness goes into the bottom battery (that provides the ground wire to the VESC), while the top one uses the other 3 wires as they all converge into the 6s port which ends up in the IMAX B6.

So in the end, on the outside of my cover, I’ll have…

1 XT60 Connector (Loop Key) 1 XT60 Connector (Charging Port) 1 6S Balance Lead

And in order to charge I will always always always remember to remove the loop key first.

END OF IMPORTANT STUFF

I know just 4000mAh 6s in series isn’t likely to get me very far very fast, but I’m planning on making this 9S or 6s2P sooner or later as budget and riding skill improves. Thanks in advance and looking forward to getting involved with this community.

EDIT: Quick format error

EDIT 2 Electric Boogaloo: Put some thought into it and decided having both the charging and Loop Key ports being the same size would be a bad move. I’ll probably order some XT90s and use that for the loop Key and an XT60 for charging.

The build went great, had the mount welded by Anthony over at Qualitig, a local welder who did an amazing job. The batteries go together in a single case, I do need to take it apart to charge because of the balance connector, but it’s not a huge deal. Eventually planning on dremeling out a slit and putting a balance lead on the outside I can put an extension on to.

The VESC was a joy to program, currently have a max of 50A to the motor while I get used to the speed. Controller seems solid, no problems so far.

Riding experience is great, I can recommend the Globe deck for a budget drop-through that can be top-mounted if needed, and while I went the now-unconventional route of a welded mount on Paris trucks I can say they feel great too.

Pictures - Sorry, phone camera is showing it’s age

That should all work well just be careful about how hot the vesc gets because you are using it on 6s. 9s would be better

[brok249]

Thanks. I’m planning on going 10sXp eventually but didn’t have the budget for it at the moment. Just to be super extra sure, my balance lead layout is correct (balance ground goes to battery that the negative terminal goes to VESC), and my current 2-plug charging layout won’t cause any damage to the VESC if the loop key is removed.

[pat.speed]

If I am reading your layout correctly ten there will be a short between te balance connectors. Will you be using a connector so that it becomes 1 6s plug?

[brok249]

Yes. That’s the plan, I linked the balance connector plug I’ll be using above the picture.

[pat.speed]

Ah yes that will work. I thought you might have been using one of eBay like I have used and shorted my lipos with it because I plugged it in the wrong way. But that connect doesn’t have the same wiring as mine so that should work fine. Good luck

[brok249]

bump because I’d like some feedback.

[Smorto]

Feedback on what exactly?

[brok249]

Just kind of thoughts in my build what I could have done better or possible future upgrades.

[brok249]

It’s my first build so I was wondering if there were any finishing-off tips “Getting started on esk8” advice.

[Smorto]

I would say just aesthetics wise, make it one enclosure and make it so the motor wires are a little more discreet. Either route them in your deck which is the more difficult option but looks the best, or simply find another way to make them look little better and without that yellow stuff on them. You could also remove the SK3 stuff on your motor and replace it with a carbon fiber vinyl of sorts? Maybe you could wrap the entire underside of your deck with the carbon vinyl.

[brok249]

Thanks with the suggestion, I’ll black heatshrink over the yellow shrink on the wires, or pare the yellow back to black. I’ve already stapled and ziptied them to the board to get them a little bit cleaner. I’ll probably get a single enclosure when I up the battery quality/count. Thanks for your help.
