Help me sort out this Building RBA and drippers thing!

Right but I was using watts in the equation to determine my amp draw. That's a correct way to calculate it right?

And VTC4 and purple 35A efest.

Got a suggestion for a quality/price charger? It can be single bay.

Just a FYI, that 35 amp Efest purple battery is only a 20 amp continuous battery. Efest advertisizes it as a 35 amp, but it has been confirmed to be a re-wrapped LG 18650HE2 battery which only has 20 amps continuous discharge rating.

I'd suggest either the Nitecore Intellicharger i2 or Xtar XP2-II for an inexpensive quality charger.
