No, it is not compulsory to charge the Ola S1 Pro 2nd Gen fully for the first time. You can start using the scooter once it has a sufficient charge to meet your immediate needs. The scooter's battery management system is designed to handle partial charging and discharging, and the battery warranty remains unaffected by how you charge it initially. For example, the Ola S1 Pro can be fast-charged to 50% in 18 minutes using an Ola Hypercharger, and it can be fully charged in approximately 6 hours and 30 minutes using the Home Charger.
