I have never charged my batteries for my Futaba and am pretty confused how to do so. The charger has so many settings and I don't want to mess up these batteries. This is what it came with. Can anyone tell me if I have this plugged into the battery correct? Do I need to use any additional cords? It came with quite a bit of stuff.. Also if you do know about this charger can you help me with the correct settings it needs to be on.
