The reason for balance charging is to avoid a cell going beyond it's critical voltage (above 4.21v per cell) where they become extremely unstable and will eventually ruin the cell or they could catch fire.
The reason why you must leave charge in them is because they self discharge and everyone knows what can also happen below 3v per cell.
All as lithium polymer needs is oxygen to combust which is what happens when they swell because the sack splits in the case.
For the sake of an extra few quid for a balance lead or balance charger is ot really worth the risk? NO
The manufacturers recommendations are there in black and white. Some people assume they know better than the manufacturer and then they wonder why cells explode and catch fire.
My Intellect cells are over 2 seasons old and still are going strong. Always balance charged and left with charge in them after each meeting.

no you Dont have to balance charge them, its advisable
no you DONT have to put them to 3.5 volts for storage....... try 3.8 to be nearer the manufactures recomendations. but after a 5 min run from full is fine.
NO lipo do NOT self discharge, or you would leave them full....
