just ordered a yuyangking YKZ7280JA. 80A square-wave controller. let's hope i don't fry the motor :lol: to help avoid that i'll be installing a smaller 11T motor sprocket (currently 13t, 53t rear)

Re: Non-overclocked Vector Light Build

it certainly looks powerful, hows it go on those flats this is where the hub motors shine! those are the volcanic sands coughed up by Mt. Pinatubo in the early 90's (which cooled the earth by about a degree). this hub does well on pavement and hardpack. but terrible off-road :lol: so it's never goi...

Re: Non-overclocked Vector Light Build

Looks cool with the battery showing thru the side panel, be careful of a short! would hate to try to pull that battery out in flames! I always think of that when there are 10x screws locking it in place inside the frame. I'm sure its a ton of fun with that controller, but make sure you have enough ...

Ouch! I would have taken a ride to the hardware store :) hats off to you haha but i did! they didn't have the exact size. it's a good opportunity to use the tap & die set anyway, these dies (dice?) get rarely used. finally got it running! the KLS7230 is too big (obviously) for this build :lol: both...

Re: MIG Welding questions

so a few months back i went ahead and got a 20lb tank of co2 and regulator. didn't cost much. in retrospect MIG is actually "cheaper" than flux-core since good fluxcore wire is expensive and not copper coated so it rusts, you can't keep it for a long time :evil: just as the OP said MIG does have a "...

Re: OpenEMoto

w/ garage built frames the limiting factor is fabbing complexity as trazor has mentioned. it's easy to design in CAD but the difficult part is actually building the damn thing. so the design goal is "good enough" rather than "best" hence no suspension linkages and such. these frames are tough to bui...

Re: A low-cost e-MTB Production log

too similar to neematic i.e. a ripoff. not good for business to be labelled as a copycat. check out the surron original design. it's easy to come up w/ a totally new design. i've done it with coreldraw in my garage

Re: Battery box that doesn't trap heat

Tesla's cooling system is primarily to ensure they last a long time. The cell cannot put out any more power than it's intrinsic properties will allow. GA is a 10A rated cell which isn't going to last a very long time at those currents inside a hailong case. in other words cells are already thermall...

Re: Battery box that doesn't trap heat

well the model S supposedly were using NCR-BE which are like GA cells w/a bit lower capacity i.e. not 30Q/25R levels of internal resistance (i've personally tested the BE and GA cells to get hot at just 7A w/o cooling). then tesla came up w/ an elaborate watercooling system to push these cells very ...

Re: Battery box that doesn't trap heat

If heat trap is a problem, its not your problem. Your problem is you are beating the pack to shit. Your discharge rate is too high, if its getting all hot. Trapping in warm is fine, especially in winter. But in a hot climate, your battery will be 110f anyway. If its getting hotter than that, then l...
