The board carry (3) three individual 10s1p battery modules for a combined battery total of 10s3p using 25R cells.
how do the batteries hold to the deck?
I like the wood enclosure a lot.
Yeah, the wood enclosure is conformal. They created that enclosure with a wood bending technique, probably vacuum formed or steam. Really light, thin, but stiff, like a wooden shell. The battery modules are built around some sort of quality plastic each and come with a set of lights. You attach them to the board thru this male pin connector that lays there on the underbelly (you can see the connector over the missing battery module empty space, below where the puck remote is)âŚ
Yâall might be very very interested in the motors
To clarify, the battery modules are CNCâd aluminum housing and each contains its own BMS. If the batteries ever get out of balance you can plug them individually into the rail system and charge them separately. Each battery is 10s1p 25R. Theyâre looking at 30q units for people who donât fly much.
Lots of other information I have from my discussions with them. Iâll write it up when I get back home!
Aluminum! ⌠hummm⌠.I thought the housing was made of plastic.
Ok so there are a few things I canât disclose publicly, so Iâll do my best with what I can disclose.
Regarding the motors, I canât disclose their supplier, but theyâre based in the US, have been making super high quality motors since forever (just not for eskate, until now). From personal testing and research knowing the supplier, I can say that if the motors theyâre making for Hoyt St. continue their usual quality, then they are likely one of the highest quality motors you can get for eskate right now, which is a bold claim to be sure. They sure are expensive, and of course much much more testing should be done and at least one of them should be sacrificed for a scientific teardown, but theyâre very nice so far. BTW the previous $300 claim is from when @Aeroquiv and I were discussing how much they might cost, and is not legitimate info from Hoyt. They likely cost upwards of $200 though
As an aside, I tested my set, and they tested 176kv. only 4kv off their 180kv claim. They are supposed to be able to handle around 150A continuous when extrapolating from the supplierâs data on their other motors. As an anecdotal benchmark, these Hoyt 5653s feel twice as strong as my SK8 6354.
Like I said before, each 10s1p is enclosed in an aluminum case containing an independent bms and voltmeter. They have two recessed female contacts that you press onto two exposed male contacts on the power rail for each battery. Itâs a really elegant system. Theyâre 25Rs, and you can balance charge each parallel individually.
Theyâre running vesc 4.12s on BLDC. It seems to be standard vesc hardware, but they moved the positioning of the shunts to the side vs. the old position on the top. No otherwise upgraded components. They went for reliability which is why they chose BLDC. The settings on their demo boards were quite low, which is why we advised them to turn them up for the highest speed mode, especially braking power. Iâm told by Hoyt that their supplier is a âhigh quality esc supplierâ. They would not disclose their vesc supplier to me.
Hereâs a pic where you can clearly see their antispark
As for the remote, in my opinion the ergonomics are not that big of a deal. I have small hands and besides it being a bit fat like an ice cream sandwich, I like it.
Yo, do those motors makers would consider making motors for DIY guys too? I am curious how they would hold abuse with high currents and heatâŚ
Also I am bit curious who is making 3 phase brushless permanent magnet motors that size outside China because so far I havenât found anyone making hobby size motors apart big size motors.
Afaik Hoyt only got the deal because Edwin is a close friend of somebody high up at the supplier. Weâve certainly been talking about running a group buy for these motors and have asked Hoyt to put in a good word for us, but the MOQ is 1000 and the motors are expensive, which means at least $200k upfront cost if we wanted to group buy⌠A tall order for as of yet largely untested motorsâŚ
BTW I edited my OP to include the continuous current itâs supposed to handle. Iâm not too sure on the figure because itâs extrapolated from the supplierâs other data; somebody needs to fully test it
150 amps continuous!!!(at the North Pole maybe)
Their epoxy or at least the copper windings are rated to 240 C continuous if that means anythingâŚ
At latest findings we figured out that epoxy temp doesnât really much affect anything its elasticity which is important because when motor can (bell) expands from heat if epoxy is not elastic it will brake its bonds
Also after looking into their website they seems to use same charger I use (generic one) and it has voltage switch 120V->240V but internally it does nothing I will upload pictures later when I am going to swap fan with noctua one in mine
Also does those battery packs has vent hole? Because if its air tight and cells goes venting it will be practically a nice bomb under you are deck
Judas Priest!! 11,700 Watt on a 180mm truck. Sign me up.
Great looking board with some dope quality parts, I got a chance to test ride it and the performance just wasnât enough for SF riding,. seems like they were having a few issues and the range was lacking comparing It to a Boosted, they werenât getting that 22miles range they claim or at least 15miles range it seem more like 7-8 miles⌠Once they fix all the bugs and hopefully make a 10s4p or bigger now we are talking and il Buy one quick
âŚand perhaps 30Q instead 25R.
What does the battery pack look like inside, it seems interesting lol
That Coleman power slide on that Hoyt board was dope
Donât know, it was sealed.
