eTronix Deans 3S Battery Harness – ET0709

The eTronix ET0709 Deans 3S Battery Harness is designed to connect three individual battery packs in series via Deans (T‑Plug) connectors, creating a combined 3S series configuration. It offers a straightforward way to build a higher-voltage setup from separate packs for RC applications where a 3S series link is required.

Overview

This compact series harness helps streamline wiring when arranging three packs in series. With Deans/T‑Plug terminations, it integrates neatly into setups that already use this popular connector format.

Suggested Compatibility

• Batteries fitted with Deans/T‑Plug connectors
• RC cars, trucks, boats and aircraft requiring a 3S series link
• Bench testing where a temporary 3S series arrangement is useful

Usage Notes

• Only for series connection of three packs; confirm polarity and connection order before use.
• For best results, use packs of the same voltage, capacity and similar state of charge.
• Verify that your ESC and electronics support the resulting voltage.
• Monitor temperatures and inspect connectors and wiring regularly.
