50 amps max rating.

Connector resistance: single connection, micro ohm: (source)

• Deans Ultra - 91
• BK 5.5 mm - 111
• Astro Zero - 190
• MPI 3mm - 340
• Generic 3mm - 360

Dean's Ultra connectors offer considerably less resistance than its competitors (Astro Zero Loss, Power Pole, 3mm bullet).

See this video for a step-by-step walkthrough of soldering Deans Ultra.

Further to what is shown in the video, remember that when soldering a female Deans Ultra to your battery, do one wire at a time. Strip, pre-tin wire, pre-tin connector, slide on heat shrink tubing, solder, shrink tubing over joint. Only then should you strip the second battery wire.
