When the battery is charged and correctly installed, the hook should emit a series of beeps indicating proper connection.
If no acoustic signal is emitted, check the following points:
1. Initial checks
Verify the battery’s charge level.
If the battery is completely discharged, the hook may not respond.
If the hook is new, make sure that any protective stickers or terminal covers on the battery have been removed before installation.
Check that the battery is positioned correctly. On the EVO-1700 model, a rounded corner should align with the matching slot.
2. Visual and mechanical inspection
Ensure that the battery is fully inserted into the hook and that nothing obstructs the connection.
Check that the locking tabs are not broken or deformed.
If damaged, do not use the battery, as it could detach during operation.
Inspect the battery and hook terminals to confirm they are in good condition and making proper contact. Remove any dirt.
3. Electrical verification
Measure the output voltage at the battery terminals using a voltmeter.
Reference values:
Evo2-1700: 12 V
Evo-1700: 24 V
If the reading is 0 V, this may indicate that:
The battery is completely discharged, or
The Battery Management System (BMS) has disabled the output for protection.
4. Battery Management System (BMS)
The BMS protects the battery against:
Overloads or sudden discharge peaks.
Excessive temperatures.
Overvoltage conditions.
If the battery is locked by the BMS, connect it to the charger to reset and restore normal operation.
Verify the battery’s charge level.
If the battery is completely discharged, the hook may not respond.
If the hook is new, make sure that any protective stickers or terminal covers on the battery have been removed before installation.
