Nice looking bike, but without a license plate the value of a roadbike drops. Also, home built batteries, no matter your skill level...

The vesc and cells alone cost 2300$. I can’t even sell the complete bike for 2000$!

Nickel work hardens easier than brass. It seems irrelevant. Brass is pretty noble and far away from steel and more causing of...

I think zinc would only get vaporized if u get it hot enough such as from a bad weld blowing through. At that point youd have a hole and...

are the ones still being made in china good? I understand a123 was sold and owned in china now. I’d get the 12ah version. I didn’t do...

There are also A123 Lifepo Pouch cells. I have bought a few 20Ah pouches. I did test the JK B2A24S20P BMS with them, 500A for 10 seconds...

Ideal would be 12ah cells with a peak of maybe 100 amps and not too long for a bike. You know any?

Any other lifepo4 that have maybe double the power and half the length? I haven’t seen data sheets of any of the 4680 size. As it is...

Been months.. what did u do? Id get these and save a lot. As long as u do two or three in parallel they have enough power.. for my...

Yea I only saw 75a peak on one site. 3c seems the peak and not enough. Even when I thought was 75a I was a bit disappointed and I had...

@byke Messaged me with what seem ideal cells for their power output (70amp peak), energy density (57 to 35 milliwatts per gram compared...

The big Tesla cylindrical cells are seeming the best energy to weight, no? When or where are they available in smaller quantities at a...

I’m just guessing but I think since the steel being on the outside, and the copper and cell connection on the inside, even if there were...
