Yah, a toaster is a near overload for just two batteries. Especially at 12v, they can get hot with humongous draws like that.
I ask because it's rare for a battery to just up and fail (except for old age and abuse) as I see here. 2-12v batteries would have experienced the same thing- if they would have run the toaster at all.
Yeah, the toaster definitely qualifies as abuse.
If we had done the same thing with the toaster with two 12v batteries, presumably only one of them would have melted down and we still would have had one useful 12v battery left to complete the trip.
