I have limited my LR venture to 2.0 ohm with my Ego batts. so far no problems except a battery change in the middle of the day instead of one batt lasting all day with standard atties. When using lr stuff I do try to be attentive to battery temperature....heat kills batteries......I always give it a chance to "cool down" if I overvape and notice the batt/carto getting too warm. As long as not overused/overheated, the life of a battery is more about the number of charge/discharge cycles than about how quickly it is discharged. LR atties use more power which means charge more often. If a battery has a life of 300 cycles, and is charged once a day it would last almost a year; use it with LR atties charging twice a day and it will be done in less than 6 months. Not because the LR atty killed it but just that it is used up. I have read that the Switches used on EGO/Riva Batts are not rated for the Amp Draw of LR atties so maybe people are having switch problems and not battery problems. For this reason I limit myself to 2.0ohm as lowest practical and am careful to be aware of overuse/overheating issues (heat is hard on switches/electrical connections too).
