    Z18-4 batteries

    Anyone running 4 batteries in their Z18? Looking to add a 4th to support additional electronics. Just want to see how well they fit.

    Thanks

    So you have a 24v trolling motor and you want 2 12v batteries for electronics?

    I have a 2108 Z18 Nitro with a 36V trolling motor. There's actually a lot of room in there. The fourth battery fits in the port side similar to how the motor battery fits on the other side.

    This pic is from my old '16 Z18 after converting to a 36v ultrex. 4 batteries will fit, but its tight.

    Depends on what you have back there already. I have three batteries, a 3 bank Dual Pro charger, oil tank and two PP pumps. If I didn't have a 2 stroke or power poles, I could easily fit two more batteries. Maybe three...
