There is amazing variation in the quality of packs out there, not just from one brand to the other but from lot to lot. Some testing mentioned here showed a 10% failure rate or reject rate. There are going to be a lot of folks with DNA200 mods that have packs that just don't stand up to use. The best thing to do is test the pack, verify the wh and the mAh and decide if performance issues are related to the pack or not. I have a great Turnigy 1300mAh pack that outperforms its rating and can easily go for two days, though that is in TC mode set at 440f with 200/200 watts on a single coil at .24 with modest to heavy vaping.[/QUOTE] Hi blueridgedog, wich model of Turnigy 1300mAh pack do you use?
