White Ember (pls don't sue me) - Redember44, 4wd, Duality, etc.

Righto, back to DIY shenanigans…

My current Brozinga iteration had been working pretty well for the past year. It did everything I needed it to do but it wasn’t really great at anything, aside from being a cable Cthulhu jumble mess (@Egtscs :joy::fu:). Decided on doing a purpose build DIY, and since I mostly ride street I decided on a bottom enclosure build.

Goals:

  • 4WD. Braking feel too good, can’t go back to 2wd.
  • Have decent range. My previous 21s6p P45b pack only gets about 26-28 miles.
  • Looks good enough to hopefully qualify for BOTY contest.

Part list:

Deck

Was debating on a Tomiboi Odachi V2, but @rafaelinmissouri build peeked my interest on a RE44 deck. Plan was to order a red/black RE44 but remembered that @SquishyCat potentially had a RE44 deck sitting around. I hit him up and ended up getting it for a pretty good deal. Had him sent it to @tomiboi for a frit job. Couple weeks later, it came in looking pretty nice.


Side by side with Brozinga.

It’s a long boi.

Enclosure

Ordered an Eboosted ecnlosure.

Trucks

What else other than @Titoxd1000 Duality trucks. Got the raw 240mm flat deck version, 12mm axle.

Drive train and internals

Most of these were transfered from Brozinga.

  • @IDEA motor mounts.
  • SKP/Radium 6485 151kv and SKP 6465 150kv.
  • Mboard 8in Novas
  • 14/67T Stooge spur gears
  • D100s x 2
  • Minnie
  • Ordered a set of white Hubba hubs and a puck receiver.

Got myself a micro USB extension with panel mount so I don’t have to open up the board when I need access to the controller. Thx @tuckjohn for the idea.

Remote

Got me a Puck 2.0 from @ARCTIC. Throttle response felt so good compares to the OG puck, but brakes felt a bit too soft. Could be due to throttle being calibrated weird on the puck shell vs Poastmote. Downloaded the Poastmote files for the Puck 2.0 and had a friend of mine model the back half of the shell for better ergonomics.

Battery

My previous 21s6p P45b pack wasn’t perform as well as I thought. @Pecos thought it was sagging a lot cause I was running 4wd even though my power draw wasn’t that high and I’m very lightweight. Around the same time tabless cells were catching on pretty fast with the EVE and BAK45d cells. I ended up ordered the Reliance RS50 cells as soon they’re available. @Pecos tests on the BAK45d cells got my hopes high for the RS50 cells. Him and I discussed on how much battery do I wanna fit inside the enclosure, I said Yes. We went with a 20s5p configuration, that will leave enough room in both the front and rear for the BMS and 2 D100s, the BMS will be sitting underneath the front controller.

Gotta love that stock charging.

Check out what @Pecos made to test charge 2000w…


I can’t… :joy:

Build time!

Mmmmm. Pretty.

Drill some holes.


Insert my… inserts.

Done.

Test mount stuffs.

Enclosure time.

Got my white stuff (silicone) in there.

Homage to the bois.

Battery seated. Mounted the power switch, charge port and micro USB port.

Installed everything else. Used velcro to keep Minnie GPS module and Puck receiver in place.

Zip tie the power connector together and job’s done. She’s tight in there.

Binding time! Found out that my stance is similar to @Ash, just mirrored.

Not bad for first time? Sealed it all up with silicone and it’s done.

All mounted and ready.

Detection time!

I’m bout to bust.

Wheels mounted and done!


Thx @BenjaminF. Don’t worry, I have that special plate coming soon. :>

Shout out to @Titoxd1000 for answering tons of questions and especially @Pecos for helping me along the way with this build. It came out way better than I thought. Now I have to wait till the next dry day for a test ride…

You mean rip it? Prob, maybe. I don’t ride that hard nor race.

Great build, super clean. I can tell how much work went into it.
What a funky battery build! 2kW charging is nuts.

Your USB solution looks way easier then my bullshit lol

Great build! love the fast charging you got.

So stoked on your build man! Getting this much battery into the enclosure and leaving room for 4wd without any top boxes or anything was a challenge. Me and Michael were brainstorming and tweaking the layout for like a month before even getting cells. Was a great project to work on with ya man and so glad your idea came together so clean. Battery build is biased at the center to push the pack and allow the absolute max space for components in the end cells of the enclosure. So fun, heres the battery build photo dump, im pretty proud of the work on your battery man - even if i had to throw every trick at making it work :laughing: still blows my mind you got it all in with the normal gasket - and your ground clearance worked out so good :face_blowing_a_kiss: :ok_hand:

What does it weigh?

Can you do 360s off bike jumps?

Haven’t weight it yet. Prob around 50-60lbs?

Yeah I managed to find the right combinations to make the extension stay out the way from the ports.

The clearance was a surprise, didn’t know I’d get that much. Gonna see how much I get once I do 6in tires.

This thing is hot. Love the white.

Awesome job on the board – really impressive builds! :clap:

I can see the mounts are set quite low. A quick tip: you can adjust the tilt angles more finely than every 22.5°—if you loosen the clamp rings and rotate them 180°, you get intermediate angles every 11.25°. This way, you can raise the motors a bit higher without hitting the deck or the baseplate of the trucks.

This build is alright, I guess.

This build has everything I would want for a street / light AT board. Have you had any issues with rocks / debris getting stuck in the open drives? I know people use them for racing all the time but that’s on ideal road conditions.

I tested a bunch of positions and this was the one that works well enough. It’s all locite in there so I don’t really want to open it up yet. :sweat_smile:

Haven’t had any real issues running them on streets. Only time stuff got stuck in there was when I rode through a LOT of wet leaves/pine needles and got a piece of branch lodged between the gears, didn’t crash or anything, just felt like the gears was grinding until I stopped to check.
