to charge receiver packs, its very trouble procedure. I never give them a proper maintenance. For those 1100mah battery, I use 1.5A for charging. Dont need to discharge them. Just charge it. If they die, just change it. U think think how much per pack. I use the receiver pack for more than 1 year. $1xx can save your time wooh.
BTW, it is very interesting that people playing miniz use 0.9A to charge their 3A battery. why we cannot use 1A to charge the receiver pack
