What batteries are recommended with the GGTS for 3.7v and 7.4v vaping? I'd prefer protected...but I guess it will really depend on price for now...I will (hopefully) be purchasing my GGTS and AVS this next week, so I'll already be out a good chunk of change - plus some high voltage atties - so I'd rather skimp on batteries now and get better ones later ('cause I'm going to need a charger, too)
thanks
