Reply to comment by professorjaytee 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

Forklifts, at least the older ones generally used lead acid batteries, or a variant, not lithium based. So they are orders of magnitude less energy dense, hence why you would need to swap every 2 hours in a forklift.

I've seen a few warehouses where they had a forklift battery swapping station where there was always one forklift ready for use, so you drive in, grab the charged one and they would swap the batteries on it and get it ready for another person.. but these warehouses had hundreds of forklifts

The point is, you need more chargers and battery units than driving units. Smaller batteries may make the issue worse, not better.
