finally starting my first build! I read tons of build threads on this awesome forum, but I’d appreciate feedback for my plan: I am aiming for 40km/h / 25mph, and I live in a very steep area, and I’d like to be able to tackle ~20% hills. I want to keep the option to change the gear ratio for increased top speed, though.
Motors: dual TB 6355 190KV should get me up the hills.
ESC: Torque ESC. I am planing to use FOC, and I read mixed reports about it. Although, I had the feeling that blown DRVs are usually caused by wrong configuration (as long as you have the v4.12). So I hope these ESCs should do.
Battery: 10s4p Samsung 30Q. Thanks for the comments, guys! I’ll go for these instead of HG2.
Trucks: Paris 195mm. I like the idea of having a bit wider trucks and wide belts. So Paris 195 mm it is.
Pulleys: 15mm 15T/40T pulley kit from @Titoxd10001. Probably 12mm would be enough, but I really want to go for maximum reliability and durability. Also I don’t like the very limited choice of belt vendors and lenghts for 12mm. This was the only option that I found to have wide belts, a large motor pulley, and still sufficient gear reduction.
Remote: Alien remote. I figured I’ll give this remote a shot. I’ll test it’s connection and failsafe feature before I actually step on the board, but I expect it to work just fine. Looks solid, not as bulky as (unmodded) GT2B, receiver with enclosure and antenna, and a fail-safe feature.
Enclosures: printed by @Eboosted I like the idea of making carbon fiber or thermoformed enclosures myself. But at the moment I have no tools and equipment whatsoever. Also I can’t wait to finally stand on an esk8. Next build I guess…
Wheels: 90 mm flywheel clones. The roads here can be rough. I want big wheels, I don’t like green wheels. So clones it is.
BMS: bypassed 30 A batterysupports. This is a tricky thing: I definitely want to bypass it and only use it for charging. On one hand the protection of the battery is not really needed if you carefully choose the settings of the VESC. But what’s more important: I don’t want this thing to “protect” my battery by deactivating my brakes… “So I totally ran into this car, but at least my battery didn’t get overcharged.” I live pretty much on a hill, so for my usual rides I will simply not fully charge the battery and live happily ever after. Since I bypass it anyway, I could probably take a way smaller BMS/balancing circuit , but I couldn’t find one with a decent balancing current. In my opinion a maximum balancing current of 65 mA is already quite small for a 12 Ah pack.
All the other stuff: I am of course aware that I’ll need tons of small pieces like an antispark and connenctors etc… First thing will be a diy spotwelder that I’m working on. I will update as the parts arrive…
