Reply to comment by ELONGATEDSNAIL in Fires from exploding e-bike batteries multiply in NYC — sometimes fatally by zsreport

Rivan does it with there vehicle batteries, Tesla does it as well. At my hospital we use mobius batteries, they last 8 hours but I've seen them disassembled and they are just a bunch of separate batteries.

It is more costly, but like the mobiuis battery I mentioned above, when one battery goes it's just one battery, a bit of smoke and that's it. The crappy one's do have bad soldering and nothing to keep that cascade from happening.

Most PEV battery packs are just 18650s in combination of series/parallel, e.g. the most common e-skateboard pack is 3s10p (3 series of 10 parallel batteries, usually Samsung 30q or 25r 18650s). Add a voltage regulation board and you've got a PEV battery.

I know some DIY battery-makers and they're crazy like lacrosse goalies. But it's way cheaper to make a 4s12p battery that can do 35mph with 40 mile range than to buy one.
