How to Size Your Battery

Batteries are sold separately. Our expandable LiFePO4 battery modules let you start small, test your boat, then scale up to the capacity you need.

Quick Battery Formula:
Motor Current (A) × Hours Needed = Battery Capacity (Ah)
Example: Your motor draws 65A and you want 3 hours → 65A × 3h = 195Ah → You'd need 4× 48V 50Ah modules (200Ah total).
48V 52ah LiFePO4
Higher capacity 150A continuous 
Built-in BMS + charger 
Safe 48V System: All EZ Inboards run on 48V safe for humans and easy to pass local marine safety regulations. You can also use any third-party 48V battery.

Will It Fit My Boat?

Yes the EZ Inboard cage mounts are designed for universal compatibility with all boat types. The adjustable brackets and screw rails let you adapt the mount to your hull. If you need a fully custom solution, the instruction manual includes a custom frame guide you can take to any local machine shop. The installation is compatible with existing gasoline engine mounts, making the swap straightforward.
