Endless Sphere

I use greenworks 40v tools for my ebikes, mower, trimmer and chainsaw. I buy the off brand replacement batteries for about $75 for 40v 6ah and parallel them for the ebike. If I were riding longer distances I would definitely go in for a bigger decent ebike battery.

Thread is a bit old? Any updates? I know some Canadians that use a Chevy Volt as a TOAD. They charge it at RV parks and use very little gas.

Happy 80th birthday!

Greenworks has a new 6ah battery that apparently fits in the same tools as the older 5ah battery. Is this a new chemistry and is anyone using this on their ev's?

Agreed - now, back to the electric tractors!

A grape harvester is a tractor.

Pellenc makes a lot of cool electric stuff for vineyards. Even an electric harvester

I ride semi recumbents these days after starting out on MTB frames. I can't go back. They're both more efficient because of the aerodynamic advantage, and dramatically more comfortable. Add a motor on, and you've negated the disadvantage in riding one uphill. I don't understand why uprights are sti...

Did anything ever come of this? I've been obsessing about 2 speed gearboxes lately and remember this concept from years ago. I recall there was another member that did this as well but I can't seem to find the thread.

THUD
He had one at the Deathrace.

I bought a 40v greenworks 2.5 ah battery on clearance at walmart for $40. I now have 3 batteries .

Winter is coming soon. If someone had a Freehold property they are living in, meaning no silly condo/strata rules. To reduce heating cost in the winter, a woodgas contraption going to a generator, that then powers heaters in the house. Maybe even find an electric water heater instead of gas, reduce...

Living in the desert southwest where wood is not very plentiful. I do my part by burning scrap wood for cutting my heating bill in winter. I have a very efficient stove, but gathering enough free wood just to heat it is a PITA. I just use my wood stove to heat from dead tree limbs and grapevines.

One data sheet I looked up shows the cell to be .2c ? That's a pretty weak discharge for battery. So lower c rate cells sag more than higher c rate cells.

No battery expert for sure, but my old lifepo4 pack was always more stronger through discharge than lipo.

There are an incredible amount of shitty 'group' owners across all social media sites. Endless Sphere is a rare gem in that moderation and ownership are generally a hands off affair. We err on the side of intervening too little. Nobody on the moderation team likes banning anyone; it's less like 'fr...

Natural gas for the win! https://techxplore.com/news/2018-06-kin ... power.html

Roadrunners everywhere here...Have a few beautiful ones that visit the vineyards daily.

And it's double the horsepower... But to keep it in budget I would look for a used 1000w scooter on craigslist and soup it up.

Nice score. My best find was a 50 buck ford think e bike. It had a 24v brushed mid drive, which liked to eat controllers. Original controller was fried, and it fried another right way. You had to ride it very careful, avoiding amps spikes. I keep trying to find a broken trek, or bbso2, but in my to...

Hall sensors for the win!

what Dogman said. That extra battery should help.
