Deans / T-Plug Connector

Both connectors use two flat, gold-plated bullet-style contacts sized for higher continuous current than a Tamiya connector can reliably carry, which matters as C-ratings and motor draw climb on tuned internals. Deans and T-plug are electrically similar but not interchangeable in shape — a gun and battery need matching connectors, or an adapter.

Because the airsoft market never fully standardised on one, most technicians keep a stock of both connector types and adapter leads on hand, and a common upgrade when rewiring a gun is to move it off Tamiya onto whichever of the two the owner's battery collection already uses.

Soldering a new connector on is a basic skill worth learning early, since a battery and a gun with mismatched connectors otherwise means either buying an adapter lead or being unable to use them together at all.
