Which is why I refuse to buy an electric vehicle.
They removed a battery from a tesla and took it inside the house to charge it. This is more a Darwin Award thing than an electric vehicle thing. They make chargers to plug into a car. Did they try to hook it to a 12 volt battery charger?
this type of 12 volt battery (made with lithium not lead) is starting to find its way in to ICE cars as well. so be sure to know what kind of battery the car has when you purchase.
