What is the difference between 11.1v and 10.8v batteries

There is no big difference, only the minimum discharge voltage of the protection plate is different;

11.1V and 10.8V batteries are 3 cells in series to get the voltage (6-cell batteries are 3 series and 2 parallel), the general voltage range of a single cell is: 3.7-4.2V, so the voltage range of the 3-cell battery in series is 11.1V-12.6V;

After 3 series, the voltage range is 10.8V. p>The battery protector discharge voltage is set to 3. 6V, after 3 strings it's 10. 8V!

--------10. 8V battery will have a longer standby time!!!! ---------
