I think what I would get excited about is using different chemistries. Like LiFePO4 for the long lifespan and better temperature tolerance. Or LTO for super long lifespan and really fast charging. Most e-bike packs I see are standard NMC Li-ion chemistry. And yeah, a high quality LiFe pack I found was really expensive. I have some used/recycled LiFe battery packs that were cheap and had a low cycle count, they would probably be good candidates.
For LiFePO4 I’d just get one of these big bulky car-like batteries I guess, in a comparably more powerful ebike. Kinda turning it into a motorbike hahaha it’s just these big LiFePO4 batteries are so freaking cheap, they go for like 100€/kWh
Yeah I have some of those, a few kWhr of them actually XD. The voltage is low for what most e-bike motors are wound for though. The batteries i was talking about before are some smaller 25.6V batteries where i could easily throw three in series to get up to typical e-bike voltage. Plus the 12.8V car style batteries would be really bulky to put in a bike frame. I could always take them apart and use the cells though.
Hmmm yeah I never thought about the voltage. I guess that could be solved by buying a 24V pack or putting two smaller 12V ones in parallel. I just freaking love how affordable LiFePO4 batteries have become
I’m guessing you meant to say in series? Yeah the monetary cost is great but I believe the human cost is the biggest positive, given that they don’t require cobalt.

Yeah I meant in series sorry. And yup, they’re much more friendly to exploitation due to the lessened rare metal amount!
