Re: GMAC vs MAC and Infineon vs Phaserunner

Just thought I would post a quick followup- I ended up doing the GMAC with a phaserunner and a 60v 17.5ah blue battery with a Sempu BB. This is on an edgerunner in a 20" wheel. So far I love it. The drag from the clutchless GMAC isn't bad at all, in spite of the numbers, in a 20" wheel it seems to c...

Re: Safety/protection requirements for 'naked' blue battery

Thanks-

I wrapped it in seran wrap, cut pieces of small foam to cover all 6 sides, then again with seran, then covered it all with gorilla tape.

Got stuck in some rain the other day, lots of puddles, all good so far.

Great thanks-

So it's safe to assume that the blue brick packs are not yet waterproofed?

Safety/protection requirements for 'naked' blue battery

Hey All- Looking at lots of different posts here on cases and bags for batteries, one thing I haven't been able to find is what sort of general requirements are considered normal for a blue/naked battery. I was thinking about making a frame from aluminum angle, and possible sides with black FRP or s...

Re: GMAC vs MAC and Infineon vs Phaserunner

Just remember, a dd, especially in a 20 inch wheel, is quite a bit more efficient overall. You'll also like regen if you're doing rides in hilly areas. If you are going up and down hills frequently, you'll need to budget for brake pads. No joke! Ok cool, and yeah I did eat through brake pads on my ...

Re: GMAC vs MAC and Infineon vs Phaserunner

How fast are you looking to go? Around 25mph or so, maybe a little faster, but we have less air up here in Denver so that's a little easier than the calculators suggest. I'm not going to loose sleep over +/- 1-2mph though (or +/- a couple lb). My main commute is almost all bike path, so no real sto...

GMAC vs MAC and Infineon vs Phaserunner

Hello all- I'm planning a new build on an edgerunner and was hoping for any feedback here. I've pretty much settled on a MAC or GMAC motor and was looking at the Grin kit vs the EM3V kit vs a bit of each. My priorities are relatively lightweight, would like to have ~1500w acceleration available, but...

Re: q128c @52 volts?

Hmm yeah- I had a q128c in my radwagon and I could hold 27-28mph on flat ground and show about 300w from the LCD (06)...that's the bike that got stolen. This was about where it reached max rpm, so you couldn't get more than about 300w into it. It doesn't seem possible that I was putting in 450w with...

Looking at doing a build with this motor here in the nearish future, one quick question- If I'm starting a buildup from scratch, what drivetrain would you guys choose? Is there a good IGH for this with wide enough spacing? Or just a 1x10 with derailleur? It seems like something with wider spacing wo...

Re: Open a q128c

since your hub is still is the wheel you can simply clamp the cap that unscrews in a vice really hard, the turn the wheel counter-clockwise. Bingo- My bench vise didn't open that big, but I went to a auto mechanic and they got it open easy-peasy. I went ahead and ordered a large bench vise for the ...

Re: Sharing Throttle, Brake and PAS with 2 contrs and 2 bats

There has to be a reference for the signal, so you have to have a ground, too, if the batteries are separate so that the battery grounds are not shared between controllers. Right that makes sense- So can I try to parallel the signal wires, as well as the ground wires, but use only one of the 5V sou...

Sharing Throttle, Brake and PAS with 2 contrs and 2 bats

Reading over all the 2wd wiring diagrams I can find, most are focused on single battery setups- The short version of my question is can I use one controllers 5v and ground and then parallel only the signal cables to the 2nd controller? And/or would I need to share grounds between the two batteries? ...
