The Baier 18V 40Ah Backpack Lithium Battery Power Unit is developed as an extended external power source for Baier cordless electric torque wrenches equipped with Metabo motors.
Its integrated output cable terminates in a Metabo-compatible battery adapter, allowing the power unit to connect directly to the battery interface of a compatible Baier torque wrench.
The backpack carrying structure provides greater mobility for wind power, mining, heavy equipment and industrial plant maintenance where frequent battery replacement or access to fixed power may affect working efficiency.
The 40 Ah battery capacity supports longer industrial bolting operations and helps reduce interruptions caused by frequent battery replacement.
Under suitable working conditions, the power unit supports:
Up to 8 hours of continuous operation
Up to 48 hours of normal intermittent use
Actual operating time depends on the connected wrench model, torque setting, workload, operating frequency and battery condition.
The attached power cable features a Metabo-compatible adapter that connects to the battery installation position of compatible Baier cordless torque wrenches.

The power unit is compatible with all Baier lithium-battery electric torque wrenches equipped with Metabo motors.
Compatibility with other tool brands or battery platforms is not guaranteed and must be confirmed separately.
The backpack power unit is designed for direct plug-in charging and does not require a separate external charger.
Before charging, disconnect the power unit from the torque wrench and connect it directly to the specified mains power supply according to the applicable input voltage and plug configuration.
Disconnect the torque wrench before charging.
Use the specified mains input and plug configuration.
Charge the unit in a dry and ventilated area.
Do not modify the charging cable, output cable or adapter.
Confirm the plug standard before placing an order.
The wearable design allows operators to carry the power unit between different bolting positions while keeping the torque wrench available for operation.
Key carrying features include:
Padded shoulder straps
Integrated carrying handle
Battery-level indicator
Portable structure for mobile maintenance
Cable routing should remain clear of rotating components, sharp edges, hot surfaces and moving machinery during operation.
