    Power cable for Dorado battery, Tigershark case, Atlas case or other Reention casing battery with PLA 0273 male connector , 5 pin PLA 0049 or 6 pin PLA 0238 connector; If you order the power cable, it is better for you to choose Ø4mm bullet connector, Ø5mm bullet connector or bare wire for the end connector for controller/motor because there is a small wire rubber O seal on the mounting, other connectors would be too big to go though the wire seal(you may need to let the wire go through the wire O seal, then solder the larger connectors). The connector is soldered with cable which you can replace your old plug on the battery easily by removing the lock screw.

    If you need a extension cable or conversion wire for your battery, then the big connector is not a problem. But please make sure you choose the right male or female connector when placing the order.
