...what charger also you recommend for the battery?
I recommend either the Efest LUC V2 or Efest LUC V4, depending upon if you need to charge 2 or 4 batteries simultaneously. Efest makes so-so batteries, but makes great chargers. Reasonable price. The LUC V4 is allegedly one of the few chargers that can charge 4 batteries simultaneously at 1 amp (speed).

What battery you use in a regulated mod depends upon the wattage that you plan to vape at and the top wattage that the mod can allegedly handle. SMOK states that the G Priv2 is capable of 240 watts. That sounds rather optimistic for a dual battery mod.
In the interests of keeping things simple:
If you use a good quality
20 amp CDR battery like the Samsung 30Q or the LG HG2 then you are good for 60 watts per battery. If using a
2-battery regulated mod, your good for 120 watts as you have two batteries. If you are using a 3-battery mod, you're good for 180.
If you use a single 30 amp CDR battery like the LG HB6 you are good up to 90 watts; with
a pair of 30 amp CDR batteries you could safely do 180 watts assuming the mod cuts off when the batteries reach 3.4 volts.
30W-60W:
LG 18650HG2 3000mah 20 amp CDR
LG 18650HE2 2500 mah 20 amp CDR
Samsung 18650 30Q, 3000 mah 20 amp CDR
Samsung 18650-25R, 2500 mah 20 amp CDR
Sony 18659VTC6 3000mAh 20A CDR
Sony 18650VTC5, 2600 mah 20 amp CDR
Sony 18650VTC4, 2100 mah 23 amp CDR
AW 18650 3000 mah 20 amp CDR
30W - 75W:
Sony 18650VTC5A, 2500 mah 25 amp CDR
60W or higher:
LG18650HB6 1500mah 30 amp CDR
LG18650HB2 1500mAh 30 amp CDR
LG18650HB4 1500mAh 30 amp CDR
If you will be vaping at less than 120 watts (more than likely), I personally would choose one of the 20A 3000mah batteries for the longest use per charge. If you want to use your so-called 240 watt mod at its fullest potential (not likely), go with the 1500mah 30A batteries. Note that the capacity of a 1500 mah battery is half that of a 3000mah battery.
