I've only been using a VinFast Evo Lite electric scooter for over three months. I find it suits my needs because it's compact and easy to navigate daily city commutes. Typically, I only need to charge the battery once a week. Lately, with Hanoi's hot weather, I've noticed the battery drains faster than before. I'm concerned whether the scooter requires maintenance or if there are specific precautions for this weather. Thank you.
