I've been using my sigelei 30 watt device lately and I've been bored and wanted to push it to its limit. I put in a fresh battery(efest 2000 mah 10 cdr) and using a 1.3 ohm cool. Hit the fire button and it says check battery. Is my battery not powerful enough or maybe counterfeit?it wouldn't even fire at 20 watts. If I try my sony vtc4 with a full charge would I be able to use the sigelei with the same coil and it should fire up correct ? Thanks
