I know everyone here likes Deans but Anderson PowerPoles can be gotten in a 75 amps variety.

My vote goes to bullet connectors. The 5.5mm or 6mm are great. They can handle 150A no problem and are more compact than PP's or using a dual Deans for the same power handling.

I've run 35AMP Power Poles exclusively on all my Motors ESC's and Lipo's for several years and never had a problem. I used to run 6S but now run 8S Lipo on my Revo.

With a Power Pole crimper, you'll never solder these together again. :intello:

that is a good choice but they're expensive... I've been running 45 amps before I used deans and bullets.... and they get warm on me...
