Reduced to $375 each, I’m eager to get these sold. Also, I’m willing to cut a deal for anyone that wants to buy multiple packs. Thanks! Tommy

Hello everyone, I’m selling some brand new, never used Samsung 50E 2170 packs. These are high quality packs, sealed with 30A BMS. Dimensions are roughly 11” x 3.5 x 3, 6.5 lbs, 665 watt hours, $375 ea These were built for our custom recumbent electric bike builds, but then we changed the...

Hi Arlo, I ask because I took interest in the subject when Doctorbass first posted in 2009, and we did a lot of testing and found it to be very useful, especially on sensorless systems. We see more torque and efficiency in Wye, and of course much more speed in Delta. We spent a whole lot of...

Back from the DEAD! Is anyone still working on the Delta/Wye switching? Tommy

Here's a highlight reel from the hill climb with our trikes. A full uncut video will follow. bS6JVhX0d8c

Thanks for all the awesome support guys! It certainly wouldn't have been possible without all we've learned from the ES forum. Since there was no official timing, we're doing our best to round up timing of the finishers. Here's what we have so far: Place|Rider|Team|Time|Average...

One easy technique that works great is the "pinch technique": (excuse the dirty drive) Place your pointer finger on the curved indentation on the front of the drive, and your thumb on the pulley. Pinch very firmly, on the edge of bulging veins firm. Tighten screws while pinching. The...

MattyCiii, We're currently stocking the Version 2.24 Beta4 units. They're the latest V2 units. We'll begin stocking the V3 units for folks when they've been debugged, we'll likely get a few early units soon for folks that want to be part of the beta testing process. The V3 units will have...

If you're going to go with a Cycle Analyst for data readout anyway, the CA-LRC is a great unit that combines the functionality of the CA, servo tester, and BEC all into one unit and allows for full control of power output, startup speed, and few other features at a very reasonable price. Grin...

The Schlumpf HSD is hard to beat if you're looking for a nice low gear, and a very tall high gear at 1:1 and 2.5:1. If you don't need as tall of a high gear, the ATS Speed drive was also designed by Florian at Schlumpf, and is a good bit more affordable with a 1:1 low, and a 1:1.65 high. With...

Green Machine, At the moment Astro is in the process of beginning full efficiency testing a few of their best-selling motors. We're expecting results back in the next couple of months. I believe Matt still has an older dyno sheet from when Bob was in charge at Astro, I believe it was for a...

I'm very excited to see this build unfold! Amberwolf is right on with charging. If you're just looking for an at-home unit, the Mastech HY5020E lab supply is a nice pick, and is somewhat portable, you can also likely find more affordable units used. For high power charging that's portable...

That's great news, Justin. Thanks again for your continued work on supporting these applications. We'll be soon placing an order and we'd be happy to share feedback on the new software as we get a couple trikes running on it. It's awesome to imagine all the possibilities for the new inputs...

Batteries Plus accepts them for free. Looks like there's six locations in Houston: http://www.batteriesplus.com/store_locator/state/TX.aspx -Tommy

Hey Kudos, It's an application called Dashware, it uses the GPS data from the Contour GPS helmetcams, and allows you to format it in a dashboard however you'd like. It's downloadable from dashware.net, it's designed for Windows. It's some pretty nice software! -Tommy
