Default Running/Charging Lipo's in Parallel

Hi, I have made up a Y lead to run my 2 Emax 1650 11.1v (15c)lipos in parallel
as singularly as the current drain from my std brushed Multiplex Moviestar at WOT draws 29amps (over the 15c Spec of the battery)

Whilst this has proved sucessful as the batterys stay cool and duration is excellent, my concern is that as the battery packs are also used in other planes (singularly) that out of balance problems might occur (between packs) would it make sence to do a top up charge using the "Y" adaptor to ensure that both packs have the same charge in them before each flight or carry on charging them singularly.

Thanks in advance for you advice.

Do you use a balancer when charging the packs?

You should really be using a balancer everytime you charge the cells - the balancer allows the cells to get an even charge and helps maintain the life and performance of the cells.

each cell in each pack will be balenced using a balance charger, however as this set up uses 2 packs could it not end up that one pack is slightly higher than the other even though both packs are balance charged?

If you leave two packs wired together in parallel, in a short period of time, they will equalize and have the same voltage.
