Charging batteries is always time consuming.
Not when you have got parallel charging!!
To parallel charge you will need a parallel harness for your lipo's. If you need to make you simply connect all the +'s to the +'s and the -'s to the -'s and that it!
This does not change the voltage of the battery but in fact the mah only increases.
for example:
charge 3 500mah 2 cells
this according to the charger is a 1500mah 2s
Thats it.
Charge rates.
This is easy if you know what 2c charge rate is or 5c or 10c ect.
To find out in amps all you do is
times the mah by the amount of c charge rate.
eg. 2200 3s with a 3c charge rate is charged at a max of 6.6amps (2200x3=6600=6.6A on the charger)
Thats all to it, Its explainde further in the video

The charge current will NOT necessarily be split evenly, so allow for that when picking a parallel charge current.
Also a dud lipo could cause the full charge to go to the other good lipo.
Allow for the worst & you'll allways be OK.

The traces on my board will burn if there is too much of a difference.
It takes some sorting before charging so it's rare that I charge more than three or 4 batteries together at one time.
