So I just moved to college.
Great!
But I would like to bring my ebike. The problem is its a 1KWh battery built from old laptop cells. I currently live in an apartment. Lithium-ion is great and all when you have a garage to charge your battery. It's not so great when you are in college and if the battery explodes, I could be liable for literally millions of dollars of the apartment complex burns to the ground.
I don't need much capacity. 10AH should do just fine. It just needs to get me around campus.
current battery specs:
42v 22.4AH. (12S10P)
All made from 96 samsung 28A cells. They get hot under load but I really don't care. It was about $20 to build. It would be dirt cheap to replace.
Bike draws 20-24 amps under full throttle.
Alternatives:
lifepo4 cells: These are very expensive. I can't go down to my local scrapyard and buy old lifepo4 cells by the pound, I have to buy them online.
NIMH: An older but still very safe battery chemistry. Not nearly as dense as li-ion but it is an option.
Lead-acid: old chemistry, cheap new too, can put out lots of amps.But they sure don't last long. Very safe.
Any suggestions?
