Hey guys. Life got a bit complicated, but found time to move this build forward.
It’s 15s A123 (49.5v nominal 54v full). focboxes are stock firmware with
M 60/-60
B 30/-12
switching frequency 30k
57v batt max
130a abs limit
I’m still on stock bushings, so I didn’t have the nuts to let it all out. I got to 28mph easy with these settings (200lb). Tons of poke, very good brakes (83mm wheels must help with that).
Some numbers:
53v (down to 50v, sag to 41.1v)
2500w
M 84a
B 59a
40degC max
30wh/mile
I think I’m already happy with this performance! It feels every bit as good as 2x6354 10s4p, accelerating and braking. I have a lot of untapped performance available. This gonna be fun.
Things I still need to do:
riptide bushings (I have them, just gotta swap them in)
Really like the pull cord on n off on top. Not so clean in this instance (maybe I’ll print One just fits the baseplate ) but got to be the easiest. And ur saying a button there would be easier and it would be until it breaks! I have yet to see a reliable switch. (Looking forward to trying the 6.6s).
What are those motor plugs n why not just bullets? Like ur velcroed holder.
Tool should be here tomorrow and and give me this week. Other taps come later in the week. No problem. I have 15 sets here almost done.
I’m really tickled by how it worked out. Proudly on display forever
Why? Better insulation and mechanical separation, will survive some abrasion, less likely to pull out with 3 ganged connections, can’t mess up the order of the phases once it’s on there.
If you look close there’s a printed wire organizer in there between the bms and focboxes. Been thinking forever on how to get control of the bird’s nest that always seems to happen.
I bought a few types – this stuff seems much better than the typical. Somewhat sealed, and much easier/nicer to deal with. Tesa tape or self fusing silicone tape (they throw some in with the loom) to seal the ends.
No actually I’m keeping the loop key. I’m just gonna make it nicer, with probably a pull cord for emergency shut off.
I’m starting to play with bms’s (the smart ones), and e-switches (rated for 100a or more). Still don’t trust them lol.
Has anyone ever tried hydro dipping trucks? I think it would look great with hubs because you can see more of the truck and you wouldn’t have to remove the mounting. Is it possile to take off the hummie hubs from the truck without breaking anything and are they glued on or screwed on? Thanks
damn its a slow process but we have the tool, bought one, and doing these starting after work tomorrow. im working the next couple days but will get it done at night and this weekend and I can take off work starting next week and for sure I really plan to have these out by Monday or Tuesday at the latest. its been a slow up with realizing the design had a problem, which showed up when @slerm bent one, so can fix that and feel better sending them abroad where it would be harder to get back and modify.
this way we really are sitting on a 12mm axle with 20mm of length before threading. 2cm from the butt should be more than enough I think and the threading remaining as well. its all good and a ok advice from machinists. gets worrisome cutting hubs with the stators and bearings all ready attached and ready to go cant afford to fuck that up.
And thanks for posting your settings!
pairing w insults.
