Im a newbie.......Ill hav to see if I can locate one of those batteries.
as faras pushing the batteries,as soon as the heli slows down,I take the battery out,let it sit for about 15 minutes,then charge it on the Thunder Power TP-610C at 0.30a for about an hour,to an hour and a half,it beeps when done........and then I recheck them with the cell checker,sometimes they will be 1 volt over,but the cells show each show very close to each other.
