I have ego 650mah battery's and with LR cartomizers they won't even work at all. The safety turns on and I wouldnt have expected this from a battery that supposed to run about 3.7v. Thats why we use LR to get a hotter and in turn bigger vape. Has anyone else had this experience? I realize batterys run hotter at first, but these have been used for about a month using 2.4ohm with some burning, and then went up to 2.8ohm with little issues. I realize they burn high, but i didn't think it would actually seize to work at all with LR. What can I do, return them? Is this a normal flaw or did they put the wrong battery in these ego casings. I am going to try and find a good cheap voltage meter if anyone has one in mind please show me....then i'll get the true number with and without a load. Thanks...
