I know this complicates things.
But maybe pondering making a top mounted jump in the middle of the deck like some of the recent production boards.
I have way less of an issue with that look…
That’s an idea.
As crazy as it sounds I do plan on strapping my charge and ride box onto the middle of this board from my Zeus at some point. I use 10s batteries with dc/dc boost converter to boost up to main pack voltage. Right now I have two 10s packs that fit in it which could provide an extra 1,100wh power. With my roughly 2,500wh main battery it should make for a heavy board with large capacity.

I too hate top mount boxes, especially ESC ones but I get it, you wanted the very max battery you could get for this build so it’s purpose built for max range.
feels like you need a purpose built ESC box too eventually. Maybe print a smaller box if you’re in the printing game or hit up @Tucker since he’s local to you and I’m sure could whip up something stupid quickly for you. 
I’ve had good luck so far with my printed one using ASA (gray here is just pla prototyping) and some flat metal to overbuild it. Just a thought.
or I’m sure @MoeStooge could make you a metal ESC box, run your antenna externally or something, have him laser cut out a portion for the lego portion to stick through etc

Wow. That’s a nice box! Ray had one or two files to choose from that I wasn’t super happy with so chose to go down this path. I hear a friend is designing a 3d print currently as well.
Yes I opted for max battery and glad I did. The D100 was the only esc I believed would comfortably fit Tomiboi double stack enclosure 10 cells wide and 8 cells long. Even still only had few mm wiggle room.

I have been doing this on a much lesser scale, with 178wh of 7s2p feeding 10s2p of BAk45D at upto 8 amps through a CC/CV booster set a bit below 10s max charge voltages.
Leaving home with it velcro cinch strapped to deck is basically 4-5 sag free miles on my comparatively low power/ low range lightweight build. I can easily notice the throttle is extra spicy, even when there is a deficit and main pack voltage is down near nominal.
I built it more thinking about just destination half way point charging, rather than charge and ride duties, but the latter includes the Anti-sag extra spicy throttle function when departing with it turned on, or soon after, and It get tons of airflow over the booster’s heatsink at speed.
I’d rather arrive at half way point fully charged or nearly so, rather than try and charge towards full once there. I also can then remove the portacharger and then the board feels lighter and more nimble for the ride home. I never expected to like using it as much as I do, even when I have no need of the extra range.
The EVE35v 7s2p feeder battery gets hot too easily, but my bad for using energy cells rather than power cells.
I also have a prebuilt and then 0.2mm copper rebuilt 104wh 7s2p that I can plug into the portacharger’s charge port to share the load and extend the range and duration of spicy throttle, and reduce its heating.
Both together basically double my potential range and eliminate range anxiety.

Is there any chance you have space under the deck between the enclosure and rear truck? It would be ideal for keeping phase wires as short as possible.
Interesting placing the esc there. Phase should be manageable with the box on top. No longer than usual.

Life’s a journey. What an effort it took getting the board up and running. Lots of time, effort, and money.
Decided I’d give the skp solos a shot since Ray is local to me and it was readily available. Got the first box wired up, (hated the way the box looked), plugged units in initially for programming (via computer and usb) no issues. Unplugged everything for final cable management, go to plug in for second time and POP, SMOKE, BOOM. Shit. Contact Ray and he gets me new unit no problems. Plug it in no problem this time. I immediately saw esc running wayyyy to hot even on normal riding conditions. The type of riding I’ll be doing will absolutely cook the unit. So decided I had to pivot. I’ll put the solos into another project.
Enter 2G300 era
From the start I knew this was the esc that this board needed. I chose the D100 (that blew) because it was the only esc I felt would comfortably fit (by few mm’s) inside my enclosure. The 2G300 required a rear top esc box that I designed. Case came together nicely only took one revision before final print. A friend helped me cnc the aluminum mounting plate, happy with how that came out.
Also pulled trigger on the new 6495 175kv motors from Radium/ Madesk8. I’ve only done 4 rides on the new setup, but between the new esc and these motors the board riiiiips. I’m pushing 130a per motor and in moderately aggressive riding they seem to like the 70-80 C range which I’m very happy with! My old 6485 205kv were getting to the 80-90c range really quickly before that setup blew up.

What a beautiful biscuit, are you running 7” novas?
Yup. Really nice tires they are!

With the re-build, I’m able to push the board so hard and it hasn’t been breaking a sweat thermally. The 6495 motors have been sitting around 70 C riding in the 40mph range.
**04 hr 56 mins including charging
This was possibly one of my faster paced rides. The EV charger I planned on stoping at was in use, had to plug into a wall and basically waste an hour charging at 15A to get me to the next EV charger. Moving on, I got to test my new fast charger with a EV outlet. I was able to get from 29% to 92% battery in 1hr 1min charging at 30A! This is what I’m talking about. No more sitting around for hours on end, game changer.
Also now using 5W30 oil in the open gears based off @Dinnye recommendation. The white lithium spray was only staying on for 15-20 miles before gears were screaming dry.
**Top speed since re-build 47.6mph @85% duty.

Jeez Louise dude!!!
Also can you share your fast charger?
Hmmm… 65 miles. That’s not bad 
But top speed is insane 
Nice and compact for how robust it is.

Yeah.. I know 
. I was going for a longer mile day but lost time to charging. It’s training, to try and keep up with you!

A friend let me have his old GoPro Hero 4.
Here’s my first time filming pov. Skip to @6:05 for the speed portion of that run, 51.41mph @88% duty.
In other news. Board is running nicely. No visible wear on Tito’s 67t spur gear at 450 miles. Same story for GDS pinions, look new at 412 miles. Dropping the 5W30 in the gears quite often now every few rides or so.
845 miles on the odometer for Street Beast. Extremely fun board, I’m still
Learning it’s capabilities.

Board’s got the zoomies lately. Highest average speed I’ve hit so far.
The intrusive thoughts are winning. No matter how much I tell myself it’s a bad idea, I keep coming back to gearing up for more speed. I’m basically at the top end of my current setup at 54/55mph (67/20 gearing).

I run my GDS pinion dry and they show very little wear even after 1k miles. Although they start to wear pretty quick once you get through the outer surface.
