The Jazrider Li-Po Battery Adapter Wire provides a direct interface between Ultra T-Plug (female) battery outputs and devices that use 4mm bullet banana plugs. It is intended for hobbyists who want a reliable, no-modification link between battery packs and standard ESC or charger inputs.
This adapter is useful when adapting Ultra T-equipped packs to equipment expecting 4mm banana plugs, including many ESCs and bench chargers. It reduces the need to reterminate existing wiring while preserving common connector standards in the pit box.
Connect the Ultra T end to the battery and insert the 4mm banana plug into the target device. Confirm correct polarity and secure seating. Periodically inspect the plug faces and insulation, and replace the adapter if mechanical damage or excessive wear is visible.
