If you’ve recently installed an Eco Battery in your golf cart or electric vehicle, you might have noticed the small CAN connectors coming off the battery. These connectors are crucial for ensuring that your battery charges completely and efficiently. In this guide, we’ll walk you through why these connectors matter and exactly how to set them up so your battery always reaches a full charge.

Why the CAN Connector Matters

Without a proper CAN (Controller Area Network) connection, your Eco Battery will never reach full charge. This isn’t just about plugging in the charger—it’s about making sure the communication link between your battery and charger is established. Think of it as the “conversation” that lets the charger know how to properly top off the battery.

Step-by-Step Guide

1. Locate the CAN Connectors

Your Eco Battery comes with two CAN connectors. One will be a blue-and-brown connector, while the other remains unused.

2. Choose the Correct Connector

Only one connector is needed. In most setups, the blue-and-brown connector is the one to use.

3. Protect the Unused Connector

The second connector isn’t necessary, but it does need to be protected. Use electrical tape or a weatherproof cap to cover it, keeping moisture, dirt, and debris out.

4. Plug Into the Charger

Take the blue-and-brown connector and plug it into the matching port on your charger. Make sure the fit is snug and secure.

5. Double-Check the Connection

Before walking away, confirm that the connector is seated properly. A loose or incomplete connection will prevent the battery from charging fully.

6. Begin Charging

With the connection established, your Eco Battery can now charge completely. Monitor the charger indicators to ensure the process is working as expected.

7. Wrap It Up Safely

Once the charge is complete, unplug the charger and safely store the cables. Always leave the unused connector taped and protected.

Quick Reference Checklist

✅ Identify your Eco Battery’s CAN connectors
✅ Use only one connector (blue-and-brown)
✅ Tape and protect the unused connector
✅ Plug the active connector into the charger
✅ Confirm the connection is solid
✅ Let the battery fully charge
✅ Unplug and secure everything after charging

Final Thoughts

Properly connecting your Eco Battery’s CAN connector isn’t just a minor detail—it’s the difference between a battery that charges halfway and one that powers you through the day with a full charge. Take a few extra moments to set it up correctly, and you’ll extend the performance and lifespan of your Eco Battery.
