So I have a reuleaux gen3 300w mod. I have been very happy with it. I get a couple of days out of it as it is a three-cell mod. I usually Vape between 60 and 70 w. I use both rdas and tanks. Just recently I have noticed the batteries discharging at a different rate. I know this mod has some protection so the battery is discharged equally. However for the first time one of the batteries is discharged completely before the other two. I am wondering if the firmware upgrade will help with this. I'm a little nervous about it as I have heard that's some mods after the upgrade have just not been the same. Does anybody recommend the upgrade? And what can I expect from it if I do upgrade? The mods about 6 months old and has served well and I like it very much I just want to keep its performance the best that I can be. Thank you for your time May the force be with you.
