Your charger is 5 amps max and 50 watts max
A 3S 1000 mAh pack needs 12.6v @ 1 amp = 12.6 watts

With a parallel rig as shown in Davids video you could do 4 packs in parallel safely
3S 4000 mAh (4 packs in parallel) 12.6v @ 3.9 maps = 49.14 watts = 4 packs charged in a little over 1 hour (Can't do 4 amps because over 50 watts!).

VERY SAFE and EASY.
