How does battery swapping work for a rented VinFast electric scooter in Da Nang?

How it works for a renter without their own account: in August 2026 a traveler described the routine — get the code at the VinFast station, message the rental company, send them the code and wait while they load it into the app. Access to rentals and battery swaps is tied to a profile with a local ID, so you cannot start a swap without the rental. The rental company, he noted, does not always reply right away.

Some rental companies have automated this: in August 2026 a renter said his rental has a Zalo chatbot — he sends it the QR code from the VinFast station and gets a fresh battery in about a minute. Before renting, ask the company whether it offers such a bot.

Swaps can take longer: in August 2026 a participant wrote that it sometimes takes about five minutes instead of one, and on a scooter with two batteries the wait doubles. On a long ride, allow for this time at the station.

According to a participant in August 2026, the VinFast app has long had a feature that lets a rental company give the renter battery-swap access, but many rentals do not use it — perhaps they are unaware of it. It is worth asking your rental whether they can grant you this access rather than looking for workarounds.
