FAQ

Do you offer mobile installs in Jacksonville Beach / Neptune Beach / Atlantic Beach?

Yes. Coastal EV provides mobile service across the Jacksonville Beaches area and nearby neighborhoods (typically within ~30 miles).

Is a lithium upgrade just “swap the battery”?

No. A proper lithium upgrade includes charger compatibility, wiring integration, secure mounting, protection, and verification testing. That’s how you avoid random cut-outs, charging issues, and premature failures.

Can you do a controller upgrade with my existing motor?

Often, yes. The right controller upgrade depends on your motor type, voltage, wiring condition, and what you want: speed, torque, or drivability. We confirm compatibility before installation.

Do you install customer-supplied parts?

Sometimes. If you already have parts, we can review compatibility and condition during consultation. If parts are incompatible or unsafe, we’ll recommend a better path before installing anything.

How long does an upgrade take?

It depends on the vehicle and wiring condition. Some installs are straightforward; others require cleanup or integration work. We’ll set expectations during consultation.
