Polarized connectors have a place in the hearts of many modelers as they make it impossible to destroy their expensive electronics and batteries by plugging them in backwards. However, they have been lacking a connector capable of extremely high currents, constantly having to increase their voltage to maintain amperage levels. But what do you do when youre maxed out on voltage and your setup requires more amperage than battery connectors on the market will handle? What if you dont want to or cant increase your voltage due to size constraints or competition rules? The answer is simple, you go green. The new Castle Creations polarized connectors will handle up to 200 amps of continuous current (for the 6.5mm version; 75 amps for the 4.0mm connectors) without breaking a sweat at any voltage level used in R/C applications. These are the highest rated polarized connector on the market. Not only that, but theyre user friendly too! Weve added ridges to the housing making them easier to grip, they accept up to massive 6 AWG wire, and weve marked them for "Battery" and "ESC" for easy reference. Batteries and ESCs arent the only things theyre useful for though. Use them on your charger leads, parallel and series harnesses, high current amp/watt meters, and anything else that needs super high current. Theyre what "going green" should REALLY mean!.
