How long does it take to charge the (11.1v) battery?
The battery that ships with the Home original is a 3S 11.1v 1550 mAh battery - it takes from 1-4 hours to charge. The larger the mAh number, the longer it will take to charge.
Always using a fire resistant container such as a battery charging bag to charge the LiPo battery.
Remove the battery from the charger once it has reached a full charge. Over discharging the battery is not recommended and might cause charging to take much longer; decrease the life expectancy of the battery; or even permanently damage it.
If the battery is swollen, do not attempt to use or charge the battery. It is damaged and cannot be restored. Dispose of it responsibly.
