Quick question- I'm having trouble finding batteries here in Japan for my iTaste VTR. Im looking for 18650 High Drain 10A batteries, typically the AW IMR 2000mAh or the efest IMR with similar specs. All reputable vendors are sold out and the ones on Amazon etc look to be fakes. What I can get my hands on are the Sony VTC5 or the purple eFest 20A or 35A batteries. Are these batteries excessive for the VTR which has a max output of 15 Watts and 5 Amps, or will they work fine?
