NEAT Trampa | 17 ply HolyPro | Infinity Trucks | E-Toxx Dual Direct Drive | APS 6384S 170kV | 12S 11.6Ah 25C | ESCape

And then I’ve made a start on getting the ESCapes sorted out. I’ll be hard-wiring them together in a loom with 2 XT90s to bring the 2 6S battery leads into a series connection via the loop key plug. So the power leads have been snipped off :astonished: 20180621_143333 And then I started filing away the cover PCB so I can route the phase wires within the minimal space I have 20180621_144641 20180621_144059 20180621_144259

Here’s how they’ll fit in the box; 20180715_213231

There’ll be the Metr Pro Module, RX and an Rx Switch crammed into the space between the 2 ESCs, and a 12V BEC on the right hand side; 20180621_151119

Everything is fitting in there perfectly with not a shred of space to spare!

Nice progress! When’s the first test ride? Must be close.

I’m hoping one evening next week. I’m away this weekend but I want to get it up and running to play with and show off at some mountainboard events we have the following weekend… Rhythm X Round 2 on the Saturday, followed by the Strong Cheese And Spam Jib Competition and camping in the evening at Harthill Adventure Park

Depending on the terrain, you may find that vescs in an enclosure will start thermal throttling. With mountain boards they truly begin to shine with heatsinks exposed to air.

I personally had no idea mine were overheating until I installed them externally with a good dual enclosure out of alu…so in case you start slowing down for no apparent reason, that will be it.

Yeah this is my biggest concern actually. I have thought about this and read mixed reports on enclosed Vs. exposed VESCs, but I do have a solution in mind to heatsink them to the outside of the case should I need to. I do want to push this setup to its limits to see what it’s capable of so only testing will tell. And I’ll have the Metr app to log data so I’ll be able to see if I have any issues…

Bit more progress on the ESCapes…

Made a perspex plate/cover to hold the 2 ESCapes together, protect the connectors and wires, and to take up the space to give a secure fit to the battery; 20180718_220729 20180718_220035

Made a plasticard separator to go between the wires and ensure better insulation between the 2; 20180718_230826 20180718_230814

Figuring out cable lengths; 20180719_194517

Final mockup of the full wiring loom; 20180719_204333

All soldered up; 20180719_232906

Soldered T-Joints will be covered in liquid electrical tape, then secured to the platicard separator and ESC housings with hot glue.

heads up, if the esc’s blow, your batteries will blow too, and vice versa

I will be putting a fuse in, don’t you worry. Just gotta get it all in the box first see where I can fit it.

Great progress! I know how long all this things take to finish :laughing: The T-Joints look interesting and dangerous at the same time, hope there is enough space/isolation between aluminium housing and solder joints. The plasticcard separator is a good idea, does it fit after soldering?

I’m planning to strap the power of 10 horses to my feet with a box of explosive batteries between my legs and it’s soldered T-Joints that look dangerous :crazy_face::laughing::rofl: But I’m confident in the isolation. Liquid electrical tape covers the joints nicely, and they’ll be well protected from vibrations once hot glued.

Speaking of dangers, I’ve got the fuse sorted out now. I’m using 200A 58V Midi Fuses, soldered some 5.5mm Bullets to resemble the blade fuse style, and coated the exposed ends in liquid electrical tape. 20180724_203334 20180725_075058

Here’s where it fits into the loom; 20180725_075205

And how it all fits in the box once the Battery’s in and the lid’s getting closed; 20180725_075421

Where do you find those fuses ? I can only find 200a / 32v on eBay

website specifies the rating as “Maximum voltage 80 Vdc - 32Vac” but they have 58V stamped on the casing

So the only other thing I’ve found time to do this week is sort out my home charging station. Found another spare flight case at work (same as my drone field charging chase). Got a 24V 25A (600W) power supply plummed into my ISDT SC-620 with parallel XT90 & 6S balance leads, so I should be able to use it at full whack to charge a 23.2Ah 6S battery @ 20A (just shy of 1C) 20180726_080945

But I have no more free time this week so won’t get it running for this weekend :disappointed: Oh well, I’m sure I can get it all finished next week…

Few more bits n bobs done…

Rx, Aux Switch & 12v BEC all wired up; (Hard wired the Rx as I had no room for connectors!) 20180801_234434

Canbus cable made and installed along with the Metr Pro Module; 20180801_234455

Pretty much everything all wired up ready to install into the box; 20180801_235107

Remaining wiring jobs to do list;

  • Connect my surprise auxiliary accessory to the Aux Switch
  • Wire up the 2 switches from the BEC
    • Switch 1 to full length 2 core cable for rear lights
    • Switch 2 to the underbox lighting
  • Direct Solder full length Phase Wires to the ESCs
  • Wire the sensor plugs onto full length 6 core cable
  • Solder connectors onto tail end of all motor wires (to fit APS motor) (I’ll mount the box and trucks to deck first to get the cable routing and lengths figured out)
  • Mount rear lights and wire up with connectors
  • Make a Spare Fuse & Spare Loop Key

So for mounting my box, I’ve gone down the solid, indestructible and super secure route…

Bring out the steel and the welder! (I may remake these in Ali in the future to shed some grams) But I’ll add some weight saving holes to these for now before painting and fitting them.

Shown on a deck drilling template; 20180802_213044

Hole centres are pretty accurate; 20180802_213058

M6 Countersunk bolts (same size as the binding bolts) go through the deck and hold the box down via these ‘Grommet Mounts’. (Bolts will be cut down to length). 20180803_080056

Vibration dampened, will allow for flex, easy to mount and detach box and it is ridiculously solid and secure! May be overkill, but I’m an Industrial Engineer so that’s what I usually do! Nice bonus is that I can carry the whole board with the box’s carry handle if I want :smile: Might get a shoulder strap for the box too.

And the underbox lighting; Just sticky back LED strip, cut into segments, wired together and cleaned up with liquid electrical tape (I’m liking this stuff, very useful). 20180801_233148

Very cool! Lots of work done. All very clean. I like it a lot. And I love the underbox lighting idea.

Won’t it be too much work to detach the box? It wouldn’t work for me. I would definitely loose the bolts. :laughing:

Thanks! There does seem to be a bit of a never ending list, but I can see the light…

Box is quick and easy enough to detach. Just 4 Allen screws, with no nuts on the other side to hold, they just wind straight in and out. And you just put them back in the Grommet Mounts after removal to keep them safe. Strength and security came first, detach-ability second.
