Smart battery features for easier monitoring

Visibility is one of the biggest advantages of this solar lithium battery. Built-in communication tools make it easier to track charge status, verify system health, and simplify setup in modern off-grid equipment.

• Bluetooth: Yes
• Mobile app access: Yes
• Remote diagnosis: Yes
• Remote firmware updates: Yes
• CAN communication: Yes
• Owner’s manual: Included
• Self-heating: Yes
• Victron communication: Yes

These smart functions are especially useful in marine, RV, and solar systems where accurate data and charging control help improve reliability over time.

Charging settings and Victron integration

Use the following charging profile for non-Victron systems to support healthy operation and stable results:

• Absorption voltage: 14.2V
• Absorption time: 15 minutes per battery
• Float voltage: 13.5V
• Equalization: Off
• Temperature compensation: Disabled

For Victron systems, connect the battery communication harness according to the manual, then confirm the battery is visible on the GX device list. Make sure the total amp-hours and the number of online modules match the installed bank.

• Connect the master unit using the waterproof bung in the blue port.
• Daisy chain the RJ45 cables from master to slave batteries as directed.
• Set the dip switches according to the product manual.
• Plug the gray RJ45 cable into the Cerbo or Ekrano GX BMS CAN port, or use VE-CAN1 / VE-CAN2 on Cerbo Mk2.
• Enable DVCC and set the controlling BMS and battery monitor to Epoch.

Once configured, the system should charge to 14.2V, hold a short absorption stage, and then float at 13.5V. For added redundancy, program your inverter/charger with the same values in case CAN communication is interrupted.
