I started out using Deans but everyone I fly with buys there packs from HK and the batteries use the yellow ends? It was just easier for me to make up a new charger, meter and ESC leads and change over to the yellow ones myself. I also scrounged around and got every type of lead I could locate and made up one charge lead that will work on every type of battery end I have run into for a friends new charger.
The "Yellow" connectors are called XT60.
HK stocks a bunch of different adapters and hydra cables for chargers.
I've obtained XT60 to EC-3, XT60 to DEANS and XT60 to the red covered banana style adapters for about 3.00 or so for a pair ( male female sets ) of adapters for each.
From a "do it yourself" standpoint I find the red covered plug style adapters the easiest to use/solder. In lieu of using Powerpolls, they are my next choice.
I've obtained or made adapters for almost any combination of connectors currently marketed. While this leaves me with a small box full of different adapters to include on my way to the field, it sure makes things easy.
Making or obtaining different adapter combos is a heck of a lot safer than putting on one type of adapter on everything you own.
I've well over a hundred different battery packs, and I'm not even going to begin to try on some of the 6s and above packs.
