To power Livescope, you'll need a battery with sufficient capacity. The size of the battery depends on several factors, including the duration of use and the power requirements of your device. It's recommended to use a battery with a capacity of at least 12-volt and 7 amp-hours (Ah) to run Livescope effectively. However, it's always better to opt for a higher capacity battery to ensure longer usage time. Considering the various options available, it's important to select a battery that matches your specific needs and preferences.
