15.3v.

DO NOT USE THIS TO REPLACE A 12v SYSTEM.

If u just gotta use it under the hood, u need to step the voltage down for it to be safe for the car.

If you wanna use it for daily driving, u need either a separate alt keeping it charged or some stepdowns to prevent the car from running on too much voltage.

Typical charge voltage i believe is 16.8v... WAY too high for a car without proper setup.
