Reply to comment by caspy7 in ELI5 why do electric vehicles have one big battery that's hard to replace once it's expired, rather than lots of smaller ones that could be swapped out based on need (to trade off range/power/weight)? by ginonofalg
Ok but you wouldn't connect 25000 AA batteries in series (ok, I would), that limits the failure points a bit.

Go watch a how it's made on Tesla or Rivian batteries. Connecting them in series/parallel is exactly what they do.

Yes but not all in series. For 25000 AA batteries that would give you about 37kV, you probably don't want/need so much.

Yes, obviously. That's why I said series/ parallel.

Tesla packs are 100Kw.

At 35kV?
