From what I've read elsewhere/one friends' report, these batteries do work well, just not for that long, as the mAh would suggest.
Safety in general /Protection features- I know nothing about, can't find much info. at all on this...careful...
I did read that each cell is actually 4 seperate 1.2V NiMH batteries stacked and wrapped together...
Kind of like a RC vehicle battery pack, but 18650 size, I believe?

Edit: 17670 size

When people talk about vaping at 5 volts, they are talking about 5 volts underload when using SR atties or cartos. Two freshly charged LiFePO4 3.2V 750mAh batts will deliver 6.4v to the atty/carto, but due to the resistance of the atty/carto and the PV's switch the volts underlaod will be quite less. I just hooked up one of COV's Voltage Meter's to my SS GGTS that measures both the volts delivered to the atty and volts underload, put two LiFePO4 3.2v batts in it and pushed the button and it read 6.4v which is what the batts are delivering to the atty/carto. I then screwed a carto in that registered 3.5 ohms resistance on my multimeter, pushed the button and it read 5.6v. This, 5.6v, is the voltage underlaod, and which equates to 8.96 watts. Watts is what determines how hot the atty/cartos burn and most people find their sweet spot in the 8 to 9 watt range. Until Imeo produces his GG variable volt/watt add-on, you have to just experiment with different batts and different atty/carto resistances to get it into the 8-9 watt range.

There is a calculator online that will do the math for you, but remember that the volts you put into the calculater are volts underload. The calculator is here:

Wouldn't the battery shake around as the TS is designed for 18mm diameter?

Take a look at the battery sizes that the ggts accommodates, the ggts can use most diameters, you can use a 14500 if you want, once its tightened down it stays put pretty well, I would never use a 14500 in mine because I do not see the point but you are talking about 1mm difference , that is nothing and like I said once tightened down it will not move. The whole point of the ggts was to allow different diameters and lengths, you do not have to use a 18mm battery.

This is my exact setup.... Captain Morgan must have tested my GGTS while I was sleeping... it NEVER leaves my possession while I am awake! :lol:

Could I just offer a word of caution on these - not necessarily the batteries themselves, but the charger. It's dodgy (will mine was at least) blew on the third charge - singed a finger, luckily wasnt too close to my eyes, could have been nasty. Charger has absolutely no marking on it whatsoever regarding output etc.

There are two chargers now which place did you get yours?

IRC (before it blew up), it didnt change colour - stayed red the whole time.

Found this on another vendor site (MV)
Custom charger for 4.8 volt NiMH Batteries.

The LED on these chargers will stay red and not turn green but the battery will be charging. Charges the 4.8 volt NiMH batteries to approximately 5.8 volts after 5 to 6 hours.

6 Volt output.

Includes Battery holder and AC Adapter. Batteries not included.

DO NOT CHARGE ANY OTHER BATTERIES IN THIS CHARGER OTHER THAN THE 4.8 VOLT NiMH BATTERY. DOING SO WILL CAUSE LI-ION OR REGULAR NIMH BATTERIES TO BE DAMAGED.
Seems a bit...dodgy that it doesn't let you know when they're charged..:?:
