Not sure about that one. The third and fourth batteries on this page, for the Meglodon & Mako, are the ones referred to in the post:
Yes, those are the same battery I linked to. I have used those batteries singly in a Silver Bullet for 5 volt vaping. No way would they fit in a BB, the batteries are too large in diameter.
The 4.8v nimh batteries themselves are pretty disappointing. First of all:

these require their very own dedicated charger. The earlier model charger didn't even change light colors (red all the time) to alert you when the batteries were charged and you were left on your own to leave them in the charger for 6 hours and remove them. The newer chargers available now at least have indicator lights that tell you when the batteries are charged now (turn from red to green). If you decide to try these batteries out, be sure to get one of the newer chargers with them.
Although the initial vaping experience with these used in my Silver Bullet was pleasing, the performance quickly drops off. The typical battery only lasts about 2-3 hours with average vaping, and after using these for about 3 weeks, they quickly dropped in usable battery life to only 45 minutes.
Considering that the re-charge time on these is 5-6 hours, they are not worth the time or money. The experience reminded me of how often I had to change batteries with the cigarette lookalike batteries. These are a poor choice of battery for use in a personal vaporizer for an extended length of time.
I tried these looking for an alternative to a Kicked Silver Bullet. I didn't wish to stack 2- 3.0v batteries in it either for 6v vaping. Overall an expensive trial that I quickly abandoned.
I finally went with a Provari and have never regretted that decision for one second.
