Made In Vadodara

Inside the line where the frames get straightened and the packs get married.

A scooter is roughly the same shape at both ends of the building. Almost nothing else about it is.

Mercury EV-Tech builds in Vadodara, Gujarat. The line is not enormous and it is not trying to be. It is arranged around a sequence that has one non-negotiable idea in it: the pack goes in late, and it goes in once.

Frame first

The frame is jigged, welded and checked for square before it goes anywhere near a painted panel. Everything downstream inherits its geometry — a wheelbase of 1350 millimetres on the DLX (LS), 1340 on the DLX GOLD — and geometry is the one thing you cannot correct later with a better component.

The pack is a separate factory

Cells are received, sorted, and matched before assembly. Cells that will live together for three years should start their lives at the same state of health, and matching them is a measurement job, not a judgement call. They are then welded into modules, wired to the BMS, sealed, and tested as a complete pack before anyone has thought about which scooter it will go into.

You cannot inspect quality into a battery at the end of the line. You either matched the cells at the start or you did not.

Marriage and end-of-line

The point where the tested pack meets the built rolling chassis is the one moment on the line where two entirely separate histories become one vehicle. After that it is harnesses, panels, lighting, and a full electrical function check — every light, every indicator, the horn, the buzzer alarm, the USB port, the reverse switch.

Then it rolls. A short test, brakes checked under load, and a final visual on the paint — because a machine whose entire appeal is a clean continuous line cannot leave with a mark on it.
