2Pairs ShareGoo XT60 to EC3 Plug Male Female Adapter Converter with 10CM 14AWG Cable Wire for RC FPV Drone Car Lipo NiMH Battery Charger ESC

These just do the job - adapting xt60 to ec3 connections. Note they are 5" long total length, 10cm, as described, of wire (approximately 4"). Depending on your airplane and/or configuration sometimes longer wires are preferred, sometimes close coupled is preferred. These are longer but work great for most applications. Decent price, beats making them yourself.

Worked great

I use these to connect EC3 batteries to my charger, which uses an XT60 plug. The adapters do the job, but as other reviewers said, the EC3 male on these adapters only goes about 2/3 of the way into the EC3 female on the battery. At that point it gets really tight and feels "wedged in". Not an issue for charging, but if I were using this in a plane I might worry about not getting full contact on the pins.

The EC3 plugs are very difficult to plug-in. XT 60 were fine. Very disappointed, sending back for a refund.

great invention
