All I can tell is my experience over the last 6 months on a daily use. First of all I´m really glad that this type of battery is much more safe than reagular lithium-ion batteries. When it is missused and overloaded it wont catch fire, it just will get really hot in worst scenario. In my two years of vaping and experimenting with these li-ion batteries something like a gassing battery has never occured to me (knock on wood) although this just happens when there is something fundamental wrong in your setup. But yeah this doesnt mean that a device with lifepo4 is something like a toy you dont have to pay attention to (: When I have to compare it to standard li-on I would describe it to something with the capacity of an 18650 Sony VTC5 with more power than a 21700 Samsung 30T and the feeling of an regulated device with two batteries becauseof the constant voltage level from full charge to empty. You notice when the battery comes to it´s end. The last 10 puffs get a little weaker and from now to then almost nothing and it´s ready for change. There will be no damage from a deep discharge! Super cool for an unregulated device without low voltage cut off. The battery is the cut off itself. In my perception, maybe its just imagination,the battery gets weaker after some usage when I return something like an hour later. But I cant really proof and its absolutely no deal. The charger is nothing special at all. I use something cheap from XTAR with 2 bays where I can set the charge cut off by switch to 3.6V. Due to the size of battery and device its more something for at home. For me its a device which has either full power or it´s empty and I have to change battery because it doesnt work at all. Its a bit more difficult to guess the battery state. But this is also something nice I think. (IMG) Discharge 1A (IMG) Discharge 30A
