Lithium battery:After the completion of a single lithium battery discharge voltage is 3V, when fully charged 4.2V;1S correspond to 3V (first light) to 4.2V (tenth lights);2S corresponds to 6V (first light) to 8.4V (tenth lights);3S correspond to 9V (first light) to 12.6V (tenth lights);4S correspond to 12V (first light) to 16.8V (tenth lights);Other series voltage and so on.2. Lead Acid Batteries6V or 12V lead-acid battery is generally:6V corresponds to 4.8V (first red light) to 6.75V (tenth lights);12V corresponds to 9.6V (first red light) to 13.5V (tenth lights);The module according to the above standard battery discharge range design, can accurately reflect the battery, so that users can readily observe the status of t
