Just wondering if leaving batteries on factory charger overnight is ok. I've heard that it can be bad.

Can be bad but I have done it many times.

I would advise getting one of them Lipo bags to be on the safe side if its something you want to do often.

Done it many times too without axny problems. Recommendation is not to leave them though. Haven't heard of anyone who has had one fail during charging.

Somebody recently posted pics on facebook of the aftermath of a fire that started while his batteries were charging overnight. Chances of that are very small but even so I too recommend a lipo bag (I always use them for charging). If you want to be extra safe, there are some people who only charge their batteries in a lipo bag inside an ammo case.

I do it all the time, just don't do it near a pile of oily rags so to speak. I put batteries on a dinner plate while there charging so it something happens there not touching anything flammable.

Wes,

As many have noted, although the likelihood of an event is minimal, it only takes one time to possibly burn down your home. I "choose" to only charge my batteries will I'm available and within close proximity. You just never know. I  usually am up before dawn and if I'm going to be flying I can have 3 completely charged batteries in about an hour (I try to land with my batteries around 30%). I use this rapid charger, which charges 3 batteries at the same time. Why take the risk if you don't have to?

Not sure if that'll be enough. The post is in groups like this one but here is an extract:"I wish this to serve as a reminder of just how dangerous these mini fire bombs actually are.
I have no doubt whatsoever that I would have been trying to escape a fully engulfed house of flames last night but for the fact that the fire broke out near my hot water heater. The heat was so intense it melted one of the water lines feeding into the heater."

I don't think it's okay. Not only for battery, but also for safety.

Remember its not just the fire aspect the fumes from a lipo are highly toxic.

It's never safe. Every LiPo "user" manual states never leave unattended.

It shuts off itself once fully charged. They do call themselves intelligent battery and has built in controllers to discharge it to storage levels over time. So its not like most dumb lipos.

Its not good to do it but I've accidentally done it because it took too long to charge and I forgot it and left it plugged in overnight. But it just remained off once it was charged.

Even a traditional dumb lipo with a smart charger, the smart charger (if i it is a good one) would shut it down once charged. So technically it could be ok. But you don't wanna risk it with lipos anyway.

There a certain amount of danger with everything you do, every second of the day. We could all be killed by a rouge asteroid, ect.ect. So I'm going to live dangerously and plug my batteries in before I go night, night. I'm I crazy mother f*#ker!!!!

I have done it many times. The Battery will only take what it needs and then stop charging. The bad wrap that Li=Ion Batteries take is from a few instances of the Batteries catching fire. Check your Batteries for any cracks or bulges. Also keep an eye on your Battery status  in your Go Program. Containers are available to place the Battery in while charging if you want to keep at ease.

It's not recommended you gave it charging overnight and in fact it's highly recommended that you monitor your batteries while charging. It's easy to forget that you're charging your batteries has happened to me a couple of times but better safe than sorry.

Y'all are crazy not monitoring your batteries while charging due to being asleep. Charging heats up the battery causing a chemical reaction and that's when lipo batteries are most likely to blow due to many factors like a manufacture defects and other factors that could cause thermal runaway.  Lipo batteries are dangerous, when you stop respecting them is when you will end up with a burnt down home.

Many people have lost their homes by not monitoring their lipo's during charging, many sad sad videos on YouTube.

Even seen Phantom 2/3 batteries catch fire, IMO no lipo is immune to thermal runaway, yes it's less likley then the old dumb lipo's but the risk is still there, this is why my lipos are charged in a 50 cal military ammo contatiner with a few holes drilled due to it being air tight (vent pressure during thermal runaway, if you dont drill then you just made a small bomb ) I also put the batteries in lipo bags from teamblacksheep and then in the .50cal box to store them.  IMO not worth gambling your life and home.  The batteries are in the most stable the colder they are, make sure not to leave them in a hot car or you will end up with a burnt car.
