On low-speed and low-endurance electric vehicles, I support lead-acid batteries because they are safer.
Comprehensive cost of use: Lead-acid batteries are cheap and have a short lifespan. Lithium batteries are expensive, but they can be used for several years. The comprehensive use cost should be about the same.
Energy density: Lead-acid batteries with the same battery life are heavier, and lithium batteries are lighter.
Safety: The most important point is that I think lead-acid batteries are safer and more reliable. The starting batteries of car engines are all lead-acid batteries. Because it must be resistant to harsh environments such as high and low temperature bumps.
Lithium batteries may catch fire when they are overcharged or at high temperatures, while lead-acid batteries will only swell and will not burn.
