Ado E-Bike Charger & Attempted Battery Theft

Dear Electric Scooters London,

Still have not needed to use my new E-Bike Charger yet.

Unfortunately for myself, recently, someone tried stealing my e-bike battery from out the front of the house where it was chained behind a normal pedal Carrera Mountain Bicycle. Fortunately he/she could not also get to the battery's cable connection so the thief left the battery unattached from lower frame.

Leaving me the opportunity to fully disconnect the batter and the internal box controller for near-future full testing of all electrical components with either a cheap-priced e-bike tester or an expensive and good multimeter.

I am not fully sure if the battery's 'damaged' key barrel can be re-attached to the e-bike frame. It appears the thief used a long screw driver to dislodge the key barrel. Help.

Regards

Amir M.
