Hello all. I have a generic looking telescoping mech mod. It came with a grey 18650 no name, no AMP printed on battery that did its job with my smaller tanks (1.2-1.5ohms). I now have an arctic tank and want to run .5ohm on it. What type of battery am i looking for or staying away from? I am going to get an IPV 4S soon but want to get on the arctic with my Mech! I know i will need at least a 10a constant discharge but is there anything else i should be careful about? I am paranoid about doing something wrong and basically making a pipe bomb. Any help is greatly appreciated. Thank you!
