Hey guys..i'm using the samsung 18650 batt as attached and they state that the max current is 5.2a. I'm using ipv4s n dual coil on tfv4 and it shows 0.25ohm.is it safe?? Does dual batt means my max current is 5.2 + 5.2? Firing at 2.50v at 25watt. Tried google but still sceptical about this. Can someone clarify my doubts please. Much appreciated.
