3.2 Installing / commissioning the battery
The battery is immediately ready for use and does not need to be activated before use.
The battery terminals are always live!
The battery must be installed in a horizontal or vertical position, but not upside down!
Ensure appropriate and secure fastening and always use suitable transportation equipment.
suitable transportation equipment.
The battery must not be allowed to move back and forth
on its own!
Ensure that the battery is always connected as intended. If this is not the case, the BMS
electronics may be irreparably damaged and lead to a possible defect in the battery!
This is not a warranty case!
Make sure that the devices to be connected are switched off before connecting them. First
connect the devices to the positive terminal (+), then to the negative terminal (-) of the
battery. Read and observe the installation instructions of the respective device manufacturer

The batteries can be connected either (all) in parallel OR in series.
Mixed wiring (parallel AND serial) is not permitted!
A maximum of 4 batteries may be connected!
Always ensure that only batteries of the same age, model, manufacturer, and state of charge
are connected together.
The voltage difference between the batteries must not be greater than 0.1 V.
Before the batteries are connected , the voltages must be equalized.
Proceed as follows:
1.
Fully charge all the batteries, adjusting the charge status in the app.
2.
Measure the voltages of the batteries to be interconnected using a multimeter.
If the voltages differ by >0.1V, charge the battery with the lowest voltage again.
3.
Repeat the process until all batteries have the same state of charge.
