Is it ok to charge battery inside car or home with no one in it?
The only two concerns are (1) battery acid and (2) hydrogen gas. Hydrogen gas is explosive, but to explode you need 4% of it in air. This means that in a 30 square meter, 2.6 meters high room, you need 0.04*78 = 3.12 cubic meters of it. Hydrogen density is 0.
Lithium-Ion Battery Recycling Frequently Asked Questions

wiring
You should maintain both ground wires. If you removed battery to chassis you would have to add engine to chassis wiring. The battery to engine wire is there to ground the alternator. Battery to chassis wiring is probably a safer, shorter, and easier run than engine to chassis anyways so why bother. You probably want 2gauge wire all the way around.
