I just did a quick read through, your description and suggestions are spot on. Stressing the point about fusing circuits at the battery is more than good advice but could be a lifesaver in a mishap. Batteries can put a few thousand (I'm not kidding) amps into a direct short causing an explosion and/or fire.
