    I need an electric TOAD....

    We’re seriously shopping a TOAD (tow behind RV) car and we’re only considering full electric. I believe the LEAF might be able to be flat towed with some careful preparations? But, finding a tow bar bracket seems next to impossible. Versa bracket might work but there’s strong chance it won’t...

    Space station battery replacement/upgrade

    Not quite as easy as when I upgraded from NiMh to Lipoly, LOL… http://phys.org/news/2017-01-spacewalking-astronauts-tackle-battery-station.html Astronauts went spacewalking Friday to hook up fancy new batteries on the International Space Station's sprawling power grid. Before venturing out...

    Throttle connectors what's this for?

    JST 3-pin throttle connectors have been with us a long time. Other than to snag on every pass through, wire loom and/or heat shrink tubing, what are those tabs for? I removed them from the connector on the left and they still work and lock fine.

    Help locating stolen eBike NYC...

    My coworker’s Schwinn Varsity I built-up was stolen in recent days from upper East side Manhattan, 93rd St area. It was kept in a shed behind apt building. Here’s some older photos - it should be noted it now sports a DD motor instead of the Q128H. A few cosmetic differences from when these...

    Ridar Systems

    Seems like a worthy new "thing" to discuss? After all the battery packs and drive systems, frames, bikes and stuff it still boils down to wrangling with traffic on 2 or 3 wheels. http://ridarsystems.com/ https://www.youtube.com/watch?v=tPcjw2H9nGc I originally heard of the Ridar system on...

    BMS alternative cell level charge protection only.

    Most of this posted in another thread https://endless-sphere.com/forums/viewtopic.php?f=14&t=82228 but I don’t wanna derail that fella’s topic and maybe those interested might not see it over there? Anyway, the deal is with my RC Lipo commuter pack I feel better using cell level charge...

    Panaracer Uff Da! appears to be discontinued…

    Dammit, that was the fattest, toughest, smooth 26” tire I could stuff into one of my Cannondale bikes. I’m big fan and user of CST Cyclops but unfortunately 26” version is just slightly too big to fit this one particular frame. So I looked and looked and found Continental RetroRide 26” x...

    Removing Handgrips

    Spraying any kind of moisture (water, glass cleaner) under grips does wonders to help release them without surprises. Trouble is, getting it (moisture) under the length of the grip. My solution is bending a long spoke to form a smooth end and use that to work under the grip along with...

    Rear Q128H planetary gears?

    Hey folks, one of my Q128H 48V rear motors finally stripped the white plastic planetary gears. I’ve emailed BMS Battery asking to buy replacements but of course no word yet. I figured it might be worth asking about alternative sources, if any, for internal parts?

    My iCharger IR measurements suck…

    I’ve always suspected built-in IR function isn’t worth a damn so I finally did a little comparison using the trusty old manual method as outlined and demonstrated on numerous YouTube RC Lipo internal resistance videos. wP0MhOcPmQY These screenshots should supply all the data needed to derive...

    Brooks saddle broke, what to do?

    Ah man, I thought Brooks’ saddles would hold up for the long-haul and even if not I was under the mistaken impression they’re lifetime warranty. Have a look - Yep, ol’ fat ass me busted one of the mounting rods last night. Goto Brooks site and it says 2-year warranty (I believe this...

    Beware - BMS + RC Lipo balance circuits…

    I’ve outfitted several RC Lipo packs with BMS/PCM. The only thing that’s really been a problem for me are rouge balance circuits. On several installations I’ve experienced balance channel transistors shorting (or turning ON when not needed) and draining down individual cells or groups. Like...

    Pedal bike loses control and crashes....

    Nothing major and I hope I don't offend the guy doing the stunt but it sure was funny and I had the hero2 rolling - Y3NZALqjngM 1st pass I do a little slow-mo and zoom but followed with the full speed, no zoom footage...

    Multi Rotor video/photography sources?

    The wife gave me permission to search around and buy a good quality MR for video/photography. Mostly for personal entertainment and exploring the canyon behind our So Ca home. Between $1-$2k USD is a likely budget. Could do more for serious pro stuff if something catches our fancy? Since...

    Why did this freewheel melt?

    I recently learned this Shimano (I assume others) have plastic spacers between some of the cogs. Obviously, it got HOT and I know why but just wondering if any clever chimps can figure it out? How ‘bout 3 guesses?

    Shipping to/from Canada/USA....

    This tangent began in another thread and since it's probably important enough to discuss at length for the good of the community, I wanted to continue the topic in it's own thread: I know businesses handle shipping easy/simple enough to Canada/USA but whenever I've fulfilled personal...

    Magnetic brake switches....

    Fairly obvious but if you wish to add eBrake switches yet keep your current levers or your bike uses integrated shifters/levers - here's what I did: I'm not a technical writer or photographer, my apologies - but a pic or two and quick description this should be fairly self-explanatory: The...

    Smoked BMS....

    So one of my Bestechpower D140 16S Lipo BMS took a dump last night. It shorted which was good that it didn't leave me stranded and attempting to bypass the damn thing in the dark/wet. But, also kinda scary that if I hadn't caught the "smell" of something amiss could've bulk charged the pack...

    Folding pedals, suggestions?

    Loving my latest Xootr Swiftfolder but would like a decent set of folding pedals. Of course, eBay has plenty $10 shipped versions but I don't mind spending more for something substantially better. Words of wisdom appreciated.....

    Bestechpower HCX-D167 channel balance always on

    Got several of these in my battery pack ecosystem but one BMS Ch #10 always discharges about 800mAh every 10 hrs when connected to the 16S RC Lipo pack. It's not self discharge - unplugged/disconnected from the BMS cells sit for weeks on end with little-no loss of voltage. When BMS connected...
