Golf carts have used mainly 48V for traction for a long time. And there are now great options for 48V LFP batteries for them. So far that usually means also running a 12V converter to power accessories. If the automotive world finally gets their act together on 48V this will be great for all kinds of DIY uses. The batteries and chargers are already here. There are a bunch of off grid and mobility applications that should be made simpler by this. Hopefully the automotive supply chain moves meaningfully around this.
