Hey (Please excuse the cheesy name)! So I’m building yet another board. This one is primarily for my commute to work which is about 8km from where I live and mostly flat. Because of that I decided to try out the chinese dual 5055 kit to see how much power it can take. I’m shooting for ~1800W and I think they’ll be able to handle it. Originally I was planning to put them on one of my other builds, but I saw the Jet Spud @JLabs was selling and couldn’t resist making a whole new build with it.
For this one I decided to go all out, Li-ion pack, fancy psychotiller enclosure and all that jazz.
The parts list is as follows:
- Jet Spud 29" BKB Edition
- 270kV Dual 5055 Ebay Kit
- Psychotiller Coupe 12" Enclosure
- Dual Torqueboards VESCs
- Bestech 60A 10S E-Switch BMS
- 10S2P 3000mAh LG HB6 Pack
- 1/4" Soft Rubber Riser Pads
- ABEC11 83mm 75A Flywheels
Currently I’m waiting on the enclosure and risers to ship, as well as the battery pack. I don’t have the necessary tools to build a pack for myself so @landonkun offered to help me out (THANK YOU THANK YOU THANK YOU!).
I went with those cells since from what I can find they seem to have the highest discharge out of any 18650s on the market, and at 1500mAh a 2P is enough range for my commute which lets me make the pack smaller and lighter.
Other things to note, the motors are way to high kV for 10S so I’m going to run them with the ERPM limit at 60k. Any advice on how to set that up to avoid any risks would be appreciated. If I find that I’m lacking power or efficiency because of the limiter, I’m going to try and re terminate the motors to wye which should drop the kV down to roughly 170kV. At that point I’ll probably increase the motor pulley size to get more top speed. If I do that I have a feeling that the belt will be rubbing up against the pulley cover, so I may need to file it down some. Also, the mounts that come with the kit aren’t adjustable in any way so I’ll likely have to file out the holes where the motor mounts on in order to properly tension the belt.
The bushings that the kit came with were complete garbage, and the baseplate they came with didn’t have a long enough kingpin bolt to put on other bushings. Because of that I swapped the baseplate out to a caliber 2 baseplate, and put some Blood Orange 89A bushings on.
I’m super exited to get this thing running, so here are some pictures of what I’ve got so far to please your eyeballs.
