The E-Meter on the dashboard is your battery monitor, and one of the most important gauges in your Sparrow. Batteries can be damaged by excessive discharge, by under-charging, and the battery pack may not be storing the amount of energy you think it is. The E-Meter shows you all the information you need about using and charging your battery including:

• Battery state of charge
• System voltage
• System current
• Amp hours that are put into or removed from your battery
• Operating time left until recharging is required
