Re: magura mt5e higo bbs02

If it just pulls it up, then you just put the switch between signal and 5v, rather than signal and ground. If it pulls it down, do it the other way. I tried that and it didn't work. Seems it didn't care for the Hall supply voltage? I didn't work much more on that approach once I started digging int...

Re: Just a strange thought

Bro, I’m sitting here freezing 20F ('think it reached 22F for the high?) do you really need to mention 40-50F as your “that cold”? LOL… 40-50F really isn’t bad. It’s more noticeable sag but nothing like when it gets down around 15F. I mostly charge right away after parking so the internal temps are ...

Re: magura mt5e higo bbs02

Have you heard about someone using mt5e as direct plug-in for BBSXX drives? BBS02 uses a magnetically actuated “Hall sensor” which pulls signal high up to about 4V. All I can find about the levers you have say “mechanical switch” so I would assume it’s just an open/close switch. I think you’ll need ...

Re: You meet the nicest people on a Honda

Short wheelbase, lightweight, high COG motos can and will be very susceptible to crosswinds and particularly strong gusts from tractor trailer trucks on the interstate. FWIW, both of mine I posted about above are LWB, and low COG, but have large surface areas, and relatively small contact patches. ...

Re: Illegal #EBikes

Where are the reports of all these "accidents" by NYC delivery riders?

And btw, not that it really matters regarding the "legality" but most of those eBikes are actually pretty close to 750W. Low C Rate battery packs.

Re: Just a strange thought

Why is it always about “cooling”? We all know cold battery packs suck and a comprehensive thermal management system should probably consider “warming” as well as cooling? At least for the charge station (like a block heater).

If I needed eBike pack in USA I would look at Luna battery packs.

Re: 12v 7ah batteries barely giving me a mile per charge

That little pack I posted normally doesn’t see more than 25A from my controllers. Occasionally though, I’ve used it as a backpack range extender for my 2kW ride and draw peaks of 35A or little more. It gets a little warm but it hasn’t suffered anything troubling. But I say this a LOT about RC Lipo: ...

Re: 12v 7ah batteries barely giving me a mile per charge

I do 16S cell count voltage and I like it. I’ve been using the Turnigy 20C 4S 5Ah hardcase. MultiStars don’t have quite the C rate and I prefer the form factor and added protection of the hardcase. Another advantage is that the hardcase come with 4mm bullet connectors which makes it much easier to s...

Re: Help on Lipo Configuration

My packs are in good enough condition that they would be fine charging without a BMS but I still tend to use one. At least for charging. High power discharge BMS can be rather large and expensive so I often discharge directly from battery leads and simply charge using a low power BMS. I’ve used thes...
