Anderson SB50 50a Connector with 10 guage wire
If you are looking for connectors this is the best deal out there. We salvaged these from professional battery packs and they all come with 10 gauge wire and ring terminals.
Perfect for quick connections of battery packs that do 50a continuous or less. These will plug right into each other. Especially great for connectors for chargers. You can put one of these connectors on your charger and one on your battery pack. You can quickly connect your charger then just pull it off when you want to disconnect. The positive and negatives line up with each other. In this scenario you would want to order 2, one for the charger and one for the battery connection.
