If you're using a parallel charging cable, like one of those, then you continue to treat it like a single cell (1s). All batteries plugged into the parallel cable charge as if they are one 'bigger' battery. The charge rate will be evenly divided between the number of batteries plugged into the cable. For example if you plug 6 batteries into the cable, it will take 6 times as long to charge as it would if you only plugged one battery into the cable.
You can bump up the charge rate according to how many batteries are plugged into the cable. But I find that since you're now charging (potentially) 6 batteries at a time there's no reason to hurry up to get the next battery on the charger. So I leave the charge rate at the original one battery rate and just let them take their time. Slow charging batteries is easier on them.
Using the celectra, you can plug in 4 parallel charging cables and charge up to 24 batteries at a time. All you need is a JST adapter like this http://www.horizonhobby.com/products...Page-_-BLH3126
for each parallel cable.
Don't mix empty batteries with full batteries on a parallel charging cable. Make sure they are all at 'roughly' the same charge (voltage) level. A little variation is OK (it's relative), so don't stress if some are discharged more than others. If you mix a full battery with an empty battery the full battery will dump it's charge into the empty battery, probably at a rate that exceeds the safe discharge/charge rate (reducing your battery life).
