[FTC]: Using Anderson Connectors for wiring.

[Al Skierkiewicz]

Skate,
While I believe the rules do not provide for you to change to a different battery connector, it is possible to replace/repair the one provided. The Molex connector is not one of my favorites but it is the one provided on the battery and the charger. There are two regular failures with these connectors. The first is that the wires pull out of the crimp or break off. The only fix is to replace the connector. The second is the female pin opens with time and becomes intermittent as shown in your video. (If you look into the end of the connector you will see the "c" shaped pin) If you use a small jewelers screwdriver, inserted between the pin and the housing (on both sides of the opening), you can return the inside diameter of the female pin to it's original size. This will give maximum contact when inserting the battery connectors.
Replacement pins and housings are available from several outlets such as Digikey and other parts houses. When you buy the pins, be sure to buy the universal crimper. It costs about $50 and I think the part is WM9999-ND. This is a two step crimp but it does the job.
