This spade connector is used to connect to 12V SLA batteries, and I believe it's the F2 variant. However it has a nice plastic shroud around it which makes it easier to remove from the batteries and since it's fitted after the crimp it doesn't get damaged as some alternative shrouds do.
I am trying to find where to buy these covers (with or without the female spade connectors) however I'm having trouble because I don't know what they are called!
Does anyone know what retailers label these parts as?
