1. Introduction
The Deeoee BE12 Battery Equalizer is designed to maintain voltage balance between individual batteries in a series-connected battery bank. It is suitable for 2V, 6V, 9V, and 12V lead-acid batteries, including Gel, Flood, and AGM types. This device ensures optimal performance and extends the lifespan of your battery system by preventing individual batteries from overcharging or undercharging.
2. Safety Information
- Always ensure correct polarity when connecting the equalizer to batteries. Incorrect connections can damage the device and batteries.
- Work in a well-ventilated area when handling batteries.
- Wear appropriate personal protective equipment, such as safety glasses and gloves.
- Do not expose the equalizer to water or excessive moisture.
- Keep out of reach of children.
- If the device appears damaged, do not attempt to use or repair it. Contact support.

5. Setup and Installation
The BE12 Battery Equalizer is designed for straightforward installation. Follow these steps carefully:
- Identify Batteries: Determine which batteries in your series bank require balancing. The BE12 is typically used between two 12V batteries in a 24V system, or multiple equalizers for larger banks.
- Power Off: Ensure all power sources to the battery bank are disconnected before installation.
- Connect Positive: Connect the red wire (V+) of the equalizer to the positive terminal of the first battery in the pair you wish to balance.
- Connect Negative: Connect the black wire (V-) of the equalizer to the negative terminal of the second battery in the pair you wish to balance.
- Intermediate Connection: The white wires are typically for the intermediate connection between the two batteries. Connect one white wire to the negative terminal of the first battery and the other white wire to the positive terminal of the second battery. This creates the common connection point for balancing.
- Secure Connections: Ensure all connections are tight and secure to prevent arcing or poor contact.
- Verify Polarity: Double-check all connections for correct polarity before restoring power.

6. Operation
Once correctly installed, the Deeoee BE12 Battery Equalizer operates automatically. It continuously monitors the voltage of the connected batteries and transfers current from the higher voltage battery to the lower voltage battery until their voltages are balanced. No user intervention is required during operation. The equalizer works both during charging and discharging cycles to maintain battery health.
7. Maintenance
The BE12 Battery Equalizer requires minimal maintenance:
- Regular Inspection: Periodically check all wire connections to ensure they remain tight and free from corrosion.
- Cleanliness: Keep the equalizer unit clean and free from dust or debris. Use a dry, soft cloth for cleaning.
- Environmental Conditions: Ensure the equalizer is not exposed to extreme temperatures or direct sunlight for prolonged periods, although it is designed for a wide operating temperature range.
8. Troubleshooting
If you encounter issues with your BE12 Battery Equalizer, consider the following:
- Uneven Battery Voltages Persist:
- Check all wiring connections for looseness or corrosion.
- Verify that the equalizer is correctly wired according to the installation instructions.
- Ensure the batteries themselves are in good condition. A severely damaged or aged battery may not be able to be balanced effectively.
- No Indication of Operation: (Note: This device typically does not have indicator lights.)
- Confirm that the batteries are connected and providing voltage.
- Check for any visible damage to the equalizer unit or its wires.
- Overheating:
- Ensure adequate ventilation around the unit.
- Verify that the battery bank configuration is within the equalizer's specified limits.
If problems persist, contact customer support for further assistance.
