Battery Banks

A bank represents batteries working together as one electrical source and lets related energy devices be associated with that bank.

Managing banks

Open Manage Banks from the main dashboard. You can create and delete banks, rename them, add optional notes, assign each battery to one bank, and link an energy device to one or more banks.

Changes to an existing bank name, notes, battery assignment, or energy-device link are saved when the value changes. There is no separate Save Changes button.

When to create a bank

Create a bank when multiple batteries are intentionally connected together to supply the same system. Common examples are parallel 12 V batteries forming a larger 12 V house bank or a group of batteries dedicated to a propulsion, starter, or auxiliary system.

How VoltSyncra summarizes a bank

Voltage: an average of available live battery voltages.
Bank Amps: the sum of available live battery-current readings.
State of charge: an average of available live battery SOC values.
Full Bank: summed battery capacity when every battery in the bank is live and reports capacity.
Ah left: summed remaining amp-hours when every battery in the bank is live and reports remaining capacity.
Time: when enough data is available, charging shows estimated time to 100%; discharging shows estimated time to 40% reserve.

Important: these are monitoring estimates based on the telemetry the batteries report. A shunt that measures the entire bank remains an important independent reference for total system current and consumed amp-hours.

Energy device links

Solar controllers, shunts, chargers, inverters, and other registered energy devices can be linked to the battery bank or banks they support. These links organize the dashboard; they do not change the configuration of the physical equipment.

What differences are normal?

Small differences in voltage, current, and BMS-reported SOC can occur because of cable resistance, BMS calibration, temperature, battery age, and connection topology. A large or rapidly increasing difference deserves investigation.

If one battery consistently carries much more or much less current than its neighbors, inspect cabling, terminations, fuses/breakers, BMS behavior, and the physical bank topology.
