Battery Adapter - Small Female (Tamiya) to Large Male (Tamiya) | FREE Delivery over €50 (ROI)
Battery adapters are available in all shapes and sizes, depending on your requirements. This is a small to large tamiya connector, and is for charging large-type batteries off of a charger with a small-type connector, or for running guns with small tamiya connectors on a large type battery. They are handy to have for anyone with large-type batteries - if you don't have 'em, then you don't need this!
If you do have them, then you probably can't do without a couple of these lying around.
