Weird theories and ideas thread! any ideas welcome

Yes of course his discharge graphs are the best. But most of those cons don’t really apply to us, only to vapes.

The voltage on LiFePO4 does sag a lot compared to li-ion, but it actually “feels like” it sags less when you’re on the board, because the sag is relatively constant across the whole discharge cycle.

The onewheel plus uses lifepo cells.
They charge super fast and don’t “sag” at all.
But range is limited

Tape is good enough. A theory. Ill at least test the conductance compared to welded or soldered

That won’t hold up to humidity/moisture or other contamination or vibration very well over the long term, methinks

At least put some solder paste under it and spot-weld it once through the solder paste?

Just an idea

Another thing In a jar or tube u have. What’s the difference between solder past and electrically conductive paste. I have that.

Or maybe the current going through the traces will build enough magnetic field they will pull the nickel down. A little.

Well I was thinking that the paste would melt and solder the two things together.

I don’t know though, just tossing ideas

Solder paste melts?! Didn’t realize that and thought it was just conductive paste. Sounds potentially much easier for soldering and could prep the wires with solder in advance. Or under a tab.

How many welds equals what conductive and worth doing I want to find out. Gotta borrow a fluke.

Typically it’s melted with hot air and I don’t know if spot welding it would melt ALL of it, and I don’t know if any non-melted paste would be harmful

But it’s just an idea to get a better connection, and it’d be fast

U ever use it? Sounds great never heard of it.

Occasionally but not much, no. I’d be concerned I guess about any unmelted paste being left over. Maybe that’s not a good idea after all. Unless you used hot air instead of spot-welding.

Put the liquid solder under all the tabs n tape it all down then hot air sounds good. I’ll have to try it. And can do it w the multimeter connected and see how it changes.

is this still relevant?

solder paste is awesome… like JB-weld solder!!! usually used for smd like mentioned…
you can’t spot weld it…

poof it’d be gone…

why can’t i get extended mtb axles so i can run 12" bmx wheels on a chain drive

those sweet double-wall rims are made for jumpin’

tires, tubes, and sprockets are easily available

Solder paste is basically tiny little balls of solder suspended in a flux solution. Flux being corrosive, in general, I would not recommend leaving solder paste that was not heated to its melting point and then cleaned with flux remover. There is no clean flux solder paste that exist but still I wouldnt.

why aren’t we cruising on 1/3 scale remote controlled cars/buggy’s with a riding platform attached on top

That’s funny… That’s how I explain my esk8 to kids when they ask how I built it.

I tell them I loved remote control cars so much that I decided to build one big enough to ride :sunglasses:

Then half of them say “oh so you turn with the remote?”

:man_facepalming:

Well technically yes I do.

Crazy idea: Bestech releases a small current BMS (like 8A charge, 8A discharge) whose JST connector, instead of this:

  • B0 (some models)
  • B1
  • B2
  • B3
  • B4
  • B5
  • B6
  • B7
  • B8
  • B9
  • B10

for example, it looks like this

  • P- (some models)
  • C-
  • C-
  • B0
  • B0
  • B1
  • B2
  • B3
  • B4
  • B5
  • B6
  • B7
  • B8
  • B9
  • B10

so that the JST cable is the only wire you need to run to the BMS at all. And the conductors are doubled so the 3A rating on the JST connector is enough to do 4A charging directly through it.

is there a way to have a battery powered disk brake connected to your front 2 wheels in case of a vesc shutdown that your remote could still control.

so if a malfunction with your internal stuff then these brakes could be battery powered and you could still brake and slow down?

thanks

I want to start at the top of a mountain road with an almost flat battery and go downhill engaging the brakes and see how far I need to go to get a full charge.
