In response to the help in charging and all. I know it will not help recharge ect, but hopefully it will prolong my shot time so that I can only use those two batteries, instead of the four; hopefully by using the two it will prolong the life on both batteries. Or at least that is my logic there. I can, and probably am wrong, but still that is my thought.
And yes I do have more than one battery, but at that same time, I am will be doing some vertical shots, and I think it would help out there a bit as well.
As weird as it sounds, I did find a few aftermarket en-en14 batteries that work just fine, no hacking needed.
However I am debating it myself still. I mean I would like the larger feel size in my hand, and the double battery capacity, however I am worried about the potential for damage to my system. Though I will admit I do have other questions about what my future shoot will be.
Granted I am shooting a festival next year, to resell the photos the year after.
