So I have been seeing this new battery "the vapor battery". What does everyone think about this battery? I'm about to purchase some batteries wondering if I should get these off play it safe with vtc4/5? http://1.bp.blogspot.com/-FKYlYAa-Vpw/U8CvA7vmRRI/AAAAAAAAXG4/RSxBUBfxbHQ/s1600/Capcvcvxture.JPG

Never heard of it.
My attitude is be wary of brands that have no reputation. A lot of Chinese makers will slap a label on there with wildly exaggerated specs. Don't know whether that is or is not the case for that battery.
If you buy any, test them first with a heavy load. If you're seeing any more voltage sag than you get with a VTC5, it's not even a 30A battery. For it to be a 40A battery it needs to see no more than 6 to 8 mOhms DCR. So with a 10A load, if voltage drops more than 80mV, it's not a 40A battery.
I can see a bad sign already in the specs, impedance states 18 mOhms which is too high. Impedance can be a little higher than DCR, but there's normally not a big difference between those specs. A battery with 18 mOhms impedance would have 20A continuous drain at most. Compare it to the VTC5 or HE2 which list impedance 12 or 13 mOhms.

Yea I'm now hearing that these batteries are not all they are amped up to be.
