Standard External Battery Pack for Spinfire Tennis Ball Machines

External battery pack to fit Spinfire Pro 2 v2 tennis ball machines.

Includes a standard battery, carry bag and cables.

The External Battery Pack makes the machine lighter (18kg instead of 24) and also allows you to store it in a location without mains power, while the battery  is charged elsewhere.

This External Battery Pack can give between 3-8 hours of play time, depending on usage. 

Can also be purchased as an extra battery for an existing machine with an external battery,  thus allowing you to have one charging whilst the other is in use.

Please note: This battery pack only fits Spinfire tennis ball machines manufactured after September 2015.
