While the Anderson Powerpoles are good for connections that need to be disconnected from time to time (and hams love them for reliable equipment connections) , I don't favor them for long term connections that may be subject to constant vibration (like a car); the contact is flat surface to flat surface with nothing to positively hold the surfaces together and prevent them rubbing together constantly except for internal tension of the blades. (Your forklifts don't move while charging so they are great for that.) IMO, for automotive use, you need to a fixed mechanical connection of the 2 parts to avoid contact surface wear, like you have with the wrap-around of a female spade connector, or a bolted connection on a solid lug like the '65 bulkhead connectors described by Bill above.
