For what it's worth, they're the only batteries I use specifically because I know they work well in both my revenger & drag.
I just ordered 5 from Liionwholesale.com. I have wismec gen 3 arriving tomorrow that needed 3 batteries unto itself, and the other two will be married to the revenger.
I looked at 30g, the brown LGs as well while they are larger capacity I really don't have a problem with the 25r lasting a day between 40-69 watts. Like I said, I know the 25 and know what to expect, if it ain't broke....
Sounds great. Just a note on battery marriage - the batteries are married to each other, not the mod. If you have two two-battery mods, married battery pairs can go in either or from one to the other. On the other hand, if you have a three battery device and a two battery device, taking two batteries from the three battery set for the two battery mod means the third battery is no longer married to the set.
As you can see, batteries are quite willing to be polygamous, but they get jealous easily and invariably divorce when that occurs.
