True. But you cant weld with one battery. For the average wheeler you dont need two batteries. If your in rocks you need them. I have an on board welder. My power supply also gives me 110 for the grinder.
Nothing worse then to break an axel hanger in a bad place.
Every battery has its pros and cons. Sears now has the Oddessy with their name on it. If and when my bats dies I'll get the sears. Mine have never failed over the 5 years I've had them. The duel system also has never failed.
