Why not look into automotive grade batteries as John CR said. I don't know the best fit for you.

A123 are very long lasting but big and heavy. Flat discharge compared to all others.

Re: 500w Vs 1000 watt DD hub motor

I bought an 1,500 edge motor (2) and each let the magnets go. I got one reguled a nd broke some so one good motor ring two good stators. I thought these was the miracle motor. Crap. Ones working but to small after the muxus 3,000. So once you go higher power or big motor it's hard to go back

Ok muxus makes a 3,000 watt motor 45mm magmets qs makes a 3,000 watt motor 50mm magnets.The qs motor weighs more and would just bury the muxus.

Re: Copper instead of Nickel, necessary?

That must be coated. Copper would green in no time where I live plus electricity. It does look good. Time to test. It would keep heat down.

Re: Why not comfort bikes?

Went up in cowboy country 3 miles away better diches and bumps and horseshoe tracks so I have to use it my bike like a roller-coaster and swing it back and forth and right on the sides of my tires. Sometimes you just don't go straight. Swingers.

I now know why I keep a junk pile. The more I do the bigger it needs to be. I would love to rummage through Dogmans garage. He knows the secret of melting motors or lifeforphysicks. Stored energy.

Re: 138mm in 135mm Aluminum dropout?

Just stretch it by hand or if you want to complicate it now go get a scissor car jack put it between the two dropouts and expand it that way.
Do put a torque arm on one or both sides.
