jaribecker123 0 Report post Posted July 25, 2017 With the battery capacity and average current consumption, you can compute the expected runtime of your project by solving the equation:Battery capacity (in mAh) / Average current consumption (in mA) = Hours of expected runtimeFor example if your project consumes 150 mA and your batteries are rated at 800 mAh at that current draw, you can can compute:800 mAh / 150 mA = 5.33 hours expected runtime Quote Share this post Link to post Share on other sites
