So, I'm curious about this. It is generally the case that leaving your batteries in the charger, once they are charged, is a no-no. But with a charger such as this, that only continues to supply enough power to keep the battery fully charged without over charging it, should this really be a concern? The obvious issue with taking them out to be used later is that once they are removed from the charger they will begin to discharge on their own, even more so when charged fully, whether it's married pairs or mech mods the inconvenience this causes for vapers is obvious.

Also, assuming that this would be safe for certain chargers that do not overcharge batteries, do you think it would significantly effect the life span of the batteries if they were left in for prolonged periods of time? My guess is that it would effect the life span, but to what degree I'm not sure so I'm looking for the experts here on these questions.

Is it safe? Yes, somewhat, kinda, maybe. Lipo batteries don't like to be left at max voltage. They don't throw tantrums or fart in your house, but they degrade if left that way. Best way to get long life out of your cells is to charge them just before use. In most cases that's just not practical, but it's the best method of getting long life from them. If your going to store them for a while, the recommended voltage for storage is 3.85v. You can go lower or higher, it's just a recommended voltage by lipo manufacturers. We use them in RC cars as well. Same batteries, just a different form factor. Pick up an rc charger and the "storage mode" ranges from 3.7 to 3.85v per cell.

But know this, the higher the charge on your battery, the more volatile the venting/flameout/explosion can be. At 3.85v a flameout becomes a little bit of smoke and heat. Take that voltage up and it becomes flame or the potential 'boom'. If they are sitting on the charger and something falls or pierces the batteries you have a direct short at max voltage.

I'm not saying leaving it on the charger will will cause anything bad to happen (as long as the charger is working correctly). I'm referring to the volatility of a fully charged battery should something "bad" happen to it while it's sitting there. Plus the constant degradation on a cell at max voltage for long periods of time. As a rule in RC (again same batteries) we don't leave our batteries at full charge for longer than a couple of hours. Keeps degradation to a minimum.

I always take out my batteries as soon as I notice they are charged. I never run a charger when I'm asleep or leave the house.

If a charger malfunctions it could start a fire. I am home enough so I can do this with all my batteries, cell phone, cordless phones, laptop, etc, with no disturbance to my lifestyle. Even if it's only a one in million chance of a fire, with no downside to the way I do it I don't see why I would take the fire risk, but as always YMMV.
