Unknowingly I left my brand new 2200mah 3s lipo battery connected to ESCs, servo's, receiver and all throughout the night and next day I found that battery is completely discharged(even lipo voltage checker isn't turning on).


Can anyone help me in recovering my lipo.
Please
All suggestions are welcomed

Thank you.

LiPo batteries should never be discharged below 3.0V/cell.
Start charging at as low current as possible like even less than 0.1A till it reaches 3v per cell then you can increase the current a little up.

Be very cautious and take preparation for any probable mishaps like fire etc.
