Ok. Guys so here I go with my first build ever. Good friend of mine has small manufacture were he is making wakeboards and wakeskates, and I approached him to make me a prototype of a mini cruiser SPUD like style deck.
DECK |
The whole deck will be 30,5’ made of Carbon Fiber, Foam, and super stiff Wooden Core. I want to keep the whole deck super stealthy so that it doesn’t look like there is battery compartment underneeth. From the bottom it will more resemble INBOARD deck. I like the curves they have in their deck.
BATTERY COMPARTMENT | Swappable battery design with quick access to all electronics. There’s going to be no screws, only special quick lock, for easy access. Something like in inboard. Battery compartment will fit 10s4p or 12s3p battery, with dual vescs. The battery compartment will be perfect to use SPACE CELL style like batteries.
BATTERY: For my needs, I need a board to ride in Los Angeles. So I opt for LONG RANGE. L.A is crazy enough and in the city the max speed I want to go is 18mph. In more safe areas I’d be happy if I go 22-24mph max. I dont have need for more speed, that’s why I am thinking of 10s4p LG HG2. That will give me around 440 WH PACK, with 80 amps, so I could go 40 amps per motor. The thing is that, I remember that @Hummie and @LEVer were recommending going 12s for their Hub motors as it stresses a lot less the motor and the battery. On the other hand I remember that @jacobbloy was saying that for his hubs unless I want top speed 10s4p is super fine for good range. What do you think guys ??? 10s4p for long range or 12s3p for keeping everything a lot less warm ? Besides that I want the whole battery pack to be exactly like what SPACE CELL’s are. Everything wrapped in plastic, with battery meter, and built in BMS.
The BMS I want for the battery is : http://www.bestechpower.com/37v10spcmbmspcbforli-ionli-polymerbatterypack/PCM-D223V1.html
Me myself I am not skilled enough to make the battery pack, so I think I’ll approach @barajabali down the road 
I hope he could help me with making this pack.
Here is a closer look at my battery compartment. Everything is super tight there, but it was very difficult to fit huge battery, and two vescs into mini cruiser.
HUB MOTORS:
I haven’t really picked my hub motors yet. It all depends how much free cash I’ll have down the road. I really like how @Hummie STEEL HUBS all in black look like and they could be a great match for this board. I also really like what @LEVer did with his 2.5v SINGLE HUB. With lowered kv I could save some money on additional vesc and I could go with his one hub. I saw some build’s here made with his SINGLE HUB and people are getting very good range on it. Since I am all about the range, I think 10s4p with 80amps to the motor could work really well here. I also talked to @Nordle who is riding his single hub with 85kv in ALPS and he says it works really well on hills. So if he is doing well in alps I think I’ll be fine with hills in L.A
VESCS: To be honest I would love to have dual vescs 6.0 from CHAKA, but who knows when Vedder finish his first beta. I think I might save some money and go now with Single Hub and go with some cheaper alternative 4.12 vesc from DIY, and later I’ll get DUAL 6.0 from Chaka !
REMOTE CONTROLLER: I am torn between these two ones: diy-electric-skateboard-kits-parts/torqueboards-2-4ghz-mini-remote-controller/
diy-electric-skateboard-kits-parts/torqueboards-2-4ghz-nano-remote-controller/
I like the trigger on the first one, and like the thumb trigger on the second one. My question is does any of these remotes has killswitch ?? I mean second button that has to be pressed in oreder to operate with speed like in boosted remote ?
PS. Oh and the good news is …after prototype testing if everything will work well, this board might go into production. There is also a plan to make a bigger 37" design but this will be totally different shape.
battery is planned to be 4x 10S in 4 rows basically? that would be a cool new layout - there really isnt a need to have cells connected in parallel first, so that could work!
