Re: Giant DH Comp Drop Out adapters and conversion

Has anyone successfully laced and dished a 20" rim into the 03-04 dh comp frame? Preferably single cross

Wouldn't mind seeing some pics of a completed build on 20's or 16/17/18 moto rims from over the years

Turn, warning, brake, high beam, low beam, horn
If you connect controls to display (or use hotkeys) you can bind them to one of these functions

Re: Li-ion cells cycle ageing

Damn 30q is getting long in the tooth @ 400 cycles or so, closing in on 29e IR wise

Would be good to see HG2 also to find out which is the longest lasting out of the 30q/Vtc6/Hg2 trinity

Re: Li-ion cells cycle ageing

Am i cucking myself by running 30q at 10a per cell then?

And if i was to use something like a 29e or m29, what discharge rate would give me the equivalent amount of voltage sag as my 30q's currently?

Re: Where would you place a 72v 25ah battery on this frame?

Too many cells, but a combination of #4 and inside the frame

Also do you own that bike? Black diamond is a much better candidate for that kind of build, what you have is the low travel less beefy xc model, teocali

I have almost the same build already completed

Re: gorilla glue epoxy/hall sensor

I used super glue as well and it's fine so far, id recommend using a decent brand like scotch or gorilla glue though since it might hold upto high temps better than generic stuff

Re: Cutting frame on Big Hit to fit battery

Why can't you just put a box under the downtube? You could probably do around 120-130 cells that way without it being too unwieldy It will look low profile and still look like a regular bike, hardly any welded frames look good except for that guy fpvlee who did the mondraker summum and he's already ...

Re: Li-ion cells cycle ageing

Here is another of my unwanted remarks 8) This level of capacity loss at 5C discharge rate should be clasiffied as excellent result. But the major problem is, that Samsung 30Q shows almost identical capacity loss under 3C and even under 1C continuous discharge rate. So at 3C continuous discharge ra...

Re: New 1000w Geared hub MXUS XFC19

How does that happen? Doesn't the enamel on the windings prevent that? It will, if there is no damage to it. But if the metal of the laminations is in direct contact with the windings, at the sharp edge of the outer lamination, and the windings are tensioned against that edge, vibration will cut th...

Re: New 1000w Geared hub MXUS XFC19

Another problem that at least their "3k" (450x) motors have is some of them end up with shorts of one (or more) phase windings to the stator laminations, at the outer lamination of the stack where the wire changes to/from the end turns. (I have one like this that I was able to fix by lifting up the...

Re: Is this dangerous to do? Need help

There is multiple shorts in that arrangement

To be honest I would just add a bluetooth bms and use that for balancing and logging, and i would wire it in based on this diagram like so
