Battery "fuel-gauge", time-to-go indicator, and much more - The remaining battery capacity depends on the ampere-hours consumed, discharge current, temperature and the age of the battery. Complex software algorithms are needed to take all these variables into account. Next to the basic display options, such as voltage, current and ampere-hours consumed, the BMV-700 series also displays the state of charge, time to go, and power consumption in Watts. The BMV-712 features an additional input which can be programmed to measure the voltage (of a second battery), battery temperature or midpoint voltage.
