I'm the same way DF. I always have some batts on the charger overnight. I do take them off first thing in the morning. I figure they are only on there from midnight to 6. Sometimes the egos are not even done charging. Perhaps someday I will venture to a mod but probably not anytime soon. The ego is about the fattest thing I use. I always like the look and colors of the regular stick batts. Plus.... how can you not like that pretty little light at the end?
Hope you're only using the slim line Ms. Bjfgator....
As for what bad things can happen, well when a lithium based battery gets overcharged easiest way to put it without getting too technical is they go boom. The bigger the batt, the bigger the boom. There are only a few chargers for lithium ion batts that I'm comfortable with leaving batts on overnight, and even those it states very clearly in the manuals do not leave batts charging unattended. Protected batts pcb is designed to prevent rapid discharge, over discharge, over charging, and overheating. That doesn't make them 100% safe, but safer. Most of the batts I use are unprotected safe chemistry high drain batts, this again doesn't mean they're safe either. Because they have no pcb and lower internal resistance if left on a non-smart charger you're asking for a blow up. The two chargers I use with them both have CC, CV, and trickle states and are routinely checked for what voltage the batts come off at every morning (4.18-4.19v on one, 4.20-4.21v on the other)....

I switched entirely to slim line chargers because I am an overnight type charger person. When the ego kits were on special I ordered several of them mainly for the bonus of the slim line chargers. I now have 7 of them and it is all I use. Plus, they fit so well on a charger strip. I have one at work and the other 6 at home. It's amazing how many stick batts you can go through in a evening when you are using tanks. If I have to leave one on during the day, DiscMan is kind enough to come over and take it off for me when it is done. He's a good brother.

Not to mortify anyone but a few days ago the DH couldn't find his bat...for 3 days this continued. The entire time it was under the bed kind of hidden plugged in to the power strip. On my side of the bed even! Thankfully no boom. Kids don't try this at home!
Out of curiosity, what difference in outcome is there if it goes boom while I'm asleep versus when I'm awake? Is there something I'd notice that I could possibly prevent the boom? Assuming Ms Gator's case above where your 'overnight' isn't 8 hours, but more like 5 or so. I've left batteries on for 5 hours during the daylight hours many times... I know about the 'battery charging bags', but wondering if there is anything else I should know?
Thanks, Mr M sir
Thanks, Mr M sir
Well, I guess that depends on where you have them plugged in. Are they under the bed?

Good answer!!
In my case, they are downstairs in my 'work area'... So if they went boom at night, it would be a whole floor away from everyone, and we would likely escape all harm. Alternatively, if they go boom during the day I'm right there above the charger, with the jewels at risk (hmmm, I may need to rethink my charging strategy!)
Blue sir easiest answer is if they go boom while you're awake you can put out the fire before it gets too bad....
Ah yes, that's kind of what I thought the answer was... I suppose it could add a few minutes to my response time, so point taken sir

Ya know, with all the home break-ins lately, you should really keep your jewels in a safe.
It's the whole reason for the not charging unattended warning Blue sir. If you're in the room if there's a failure you have a better chance of reacting properly before it becomes a truly serious problem. If you're asleep in the room with them may not wake up in time so to speak. Not saying any of this to start paranoia, just making sure everyone is informed. What makes a lithium based batt dangerous is the very element that makes them work... When a lithium ion batt gets too hot lithium plating takes place and multiple short circuits can occur. This is why overcharging them is so dangerous....
Sure, it makes perfect sense Mr M. Understand this is true of all battery charging and is just standard safety practice and nothing to be deeply concerned about beyond taking proper steps.

What we see is a few things, the cell has been degraded by being constantly drained under heavy load when not testing, and with the cool carts near the end had to take more puffs per minute to be satisfied because of the large voltage drop. Personally view the OMGad is a waste to use with cool and wow carts, because of the extra battery life and harder draw the tanks perform better than the standard cartos. The hard draw was really brought to light with the cool carts, and outside of this test won't ever be using them on here again. The 1.5 and 2.0 ohm dc's are my personal choice with this mod....
