Parallel Charging Boards
I'm new to this Lipo thing and have started with 2 sets of 3 Lipo packs that have a P designation, as in: 1300mAh 2S1P 20C 7.4v and 1800mAh 3S1P 20C 11.1v.
My understanding is that within a pack with this designation 2 or more of the cells are connected in parallel.
Is this a pack that should NOT be charged on a parallel charging board; or, is it no different, other than the same cautions?
PS I have an Accucel-6 charger from Turnigy, I might buy a second, but, this sounds like a cheaper option... for now

2S 1P equals 2 cells in series the 1P means 1 set ofcells in parallel which is what makes it confusing.
3S 1P equals 3 cells in series and the 1P same as above.
Years ago there wer no large capacitry LiPoly cells. Inorder to have a 3S (nonimal 11.1V ) 3000 mAh LiPoly required 9 cells of 3.7V and 1000 mAh each Such a 9cells 3000 mAh LiPolys would be listed as a 3S3P 11.1V 3000 mAh.
Cells in series increase volts , cells in parallel increase capacity (mAh).
Snip from one of the old Sticky post
Parallel charging boards and harnesses are for charging more than one LiPoly of the same voltage (number of cells in series) at a time such as 2 to 6 3S 11.1V ones. They can be the same capacity or different capacities but must be close to the same state of charge (voltage) before connecting them in parallel.
