Learn how to wire a Female EC8 to Ring Terminal to your 12V lead-acid battery and connect it safely to a Yeti power station, with step-by-step checks and common mistakes.

Quick answer

Use the Female EC8 to Ring Terminal to connect a single 12V lead-acid battery to your Yeti power station: attach the ring terminal to the battery post, plug the EC8 end into the station's EC8 input, and keep the inline 80-amp fuse in place. For more than one additional battery, you also need the Male EC8 to Ring Terminal Cable.

Why the EC8 connector and fuse matter

The EC8 connector is a keyed, polarity-specific plug that prevents accidental reverse connections. The supplied 80-amp fuse protects the cable and your power station from overcurrent if the battery is drained too quickly or a short occurs. Skipping the fuse or using a lower-rated one defeats that protection.

The 8-gauge, 27-inch cable is sized for the current a single 12V lead-acid battery can deliver to a Yeti station. If you plan to add a second battery, the current path changes and you must use the male EC8 to ring terminal cable as well; the female cable alone will not parallel two batteries correctly.

When this cable is the right choice

This cable is intended for AGM lead-acid batteries, not lithium or other chemistries. It works with Yeti power stations that have an EC8 input. If your station uses a different connector, this cable will not fit. Also, if you need to extend the run beyond 27 inches, you will need a longer cable or an extension; do not splice this one unless you are qualified to make a safe, fused connection.

Step-by-step EC8 ring terminal installation

Power down and disconnect: Turn off your Yeti power station and any connected loads. Disconnect the battery's negative terminal first, then the positive. This order reduces the chance of a short through your tools. Always remove the negative cable first and reconnect it last.
Mount the fuse holder: Place the inline 80-amp fuse holder close to the battery's positive terminal, within a few inches if possible, so the unfused length of cable is as short as practical. Do not remove the fuse. A fuse near the battery protects the whole run; a fuse near the station leaves most of the cable unprotected.
Attach the ring terminal to the battery: Connect the ring terminal to the battery's positive post (red) and tighten the nut or bolt firmly. Give the cable a gentle tug to confirm it is secure. If your battery uses a different post size, use the correct adapter—do not force the ring. A loose ring terminal can heat up and melt; check tightness after the first use.
Route and secure the cable: Run the cable away from sharp edges, heat sources, and moving parts. Use the supplied EC8 cable clamp to hold the connector firmly at the power station end, leaving a small service loop so the plug is not under tension. Avoid routing the cable through a door or window that could pinch it.
Plug into the Yeti station: Align the keyed EC8 connector and push it fully into the station's EC8 input. You should feel or hear a click. Do not force it; if it does not seat easily, check orientation and for obstructions. A partially seated EC8 connector can arc and damage the plug; confirm it is fully engaged.
Test and inspect: Reconnect the battery's negative terminal last. Turn on the station and check that it recognizes the battery input. After a few minutes, feel the fuse holder and connections for unusual warmth. If anything is hot, disconnect and recheck the connections. Warmth beyond slightly above ambient indicates a problem; stop and investigate.

Product facts

Female EC8 to Ring Terminal: Includes an 80-amp fuse for overcurrent protection and an EC8 cable clamp to keep the connector secured. The fuse protects your Yeti station and wiring from a short or overload, and the clamp prevents the EC8 plug from vibrating loose during use.
