For my first couple years living in Bedford I thought the small offshoot trail WAS the minuteman, goes well past the Billerica border and runs roughly parallel to Route 4. It crosses the road many times giving ample opportunity to get on and off. The Minuteman itself ends in Bedford next to a...

Because I couldn't find a thread that very clearly explained it: 1: put in by clicking on where it says youtube on the top bar. 2: Take youtube url, say http://www.youtube.com/watch?v=47lwPE_xGik 3: Delete the = sign and everything left of it 4: In this case now you should have 47lwPE_xGik...

Had mistakenly posted a testing report in photo & video, sorry started a post with video and got sidetracked. Here is a helmetcam video of a ride. 47lwPE_xGik The bike is the same one detailed in the report found here http://endless-sphere.com/forums/viewtopic.php?f=4&t=46545 edited to fix...

My test ebike has gone thru three major iterations. It serves as a test bed and as my means of transportation. Take 3: The Bike Frame: Chinese rigid diamond frame steel mountain bike, no front shocks, cheap rim brakes, freebee, relative got it at a yardsale and didn't want it so gave it to me...

The ebike batteries being of the type was a false alarm. It turns out the higher than normal voltage on my bike batteries was an measurement error caused by a the cheap voltmeter built into the battery charger. It indicates 13 volts for each block fully charged, which is very close to an...

"If your charger pulls it to 16.8v" It does not. It charges to a little over 14 volts and AFTER removing it from the charger it then climbs from 14 volts off the charger to a final open circuit voltage of 16.8 over a few hours. under a 30 amp load it drops to 16.2 volts I bought the original...

6 or 7 mph with 4 people aboard, 10 mph with just me. Old Town stillwater 17 fiberglass canoe. with just me in at full speed more than half the boat is out of the water and the bottom oilcans with every ripple. When I go in the front to level it: wow. At throttle 3 or 4 out of 5 depending on...

Oddly enough a very wonderful suprise inside. They ain't lead acid! No, as far as I can figure these are AlMg/neutral/Fe2O3. My first was a Deka group 24 I got for my trolling motor. I had modded the motor to the point that it would plane my uncle's stillwater 17 with 4 people on board. The...

First of all there a lot of things being called nickle zinc. Most can be broken into 3 categories: gen 1: these have conventional separators, normal (slightly impure) zinc, and have a cycle life from 25 to 50 for conventional separators to 100 cycles for plate pocket. most older batteries are...

No, europositron promised but intentionally did not deliver a 1.5 volt per cell aluminum-air battery with some sort of proprietary aqueous amide electrolyte and a long life high rate bifunctional air cathode. The best story i have been able to obtain is that Partanen took over $2,000,000 usd...

anyone ever heard of these things before, I met someone who says a former UMass Lowell professor was very knowledgeable about them but the university no longer had contact info for him. I dimly recall seeing one of these being sold off the shelf somewhere in Virginia when I was a kid in the...

I am going to call grin cyclery and see what they have to say about issues with the Bmc and their controllers; the modded infineons, and the sensorless crystalytes which they claim will work with a motor that normally uses hall sensors. The website mentions that the infineons have the same...

Found someone selling the newest sensorless crystalyte controllers, very expensive but would they be a better match? It's just they want $200 for the 40 amp 36 or 48 volt unit. They replaced the mosfets; the new mosfets are continuous, not peak rated at 100 volts and 100 amps PER EACH...

Does Cell_Man have a web site and what controller of his should I buy, and what does he charge?

I confess to murdering a cheapo controller. It was a 36 volt 25 amp controller, I was and am running a 36 volt bank of monster 26 amp hour semi deep cycle powersonic AGM batts. There is a plug you can pull to improve hill performance or run at over 20 mph, on the cheap controller I suspect...
