It depends what charger you have. If you are only using the stock charger then NO - DON'T DO IT.
If you have something like the Powerlab8 then it's internal saftey alogorithms monitor everthing in sight. I use a Powerlab and charge 6 batteries at once at 2C. Because I have 6 batteries this means that the first Lipo I use has rested for over half an hour before it gets a charge but the last one is still warm! I do usually allow 5 minutes cool down to be fare but that's it.
My advice... Hot is not ok to recharge, Warm is, so long as you are using a good quality charger.

Good question.
My friend's truck caught on fire because he was charging an unbalanced pack. I'm not sure what sort of charger he was using. Astro Flight sells the "Blinky" and Common Sense sells several different stand alone balancers and so does Thunder Power.
A balancing charger is a good thing but out-of-balance packs aren't always on a charger. Out-of-balance packs can cause problems. It's a good idea to make sure they are balanced before, during and after charging.

Since my charger balances as it charges, what would be the definition of an out of balance battery and how would you balance a battery without charging it. Sorry, it just sounds like an unnecessary step with a battery charger that charges and balances at the same time. Even brand new batteries can be off by .01. I don't really consider that as being out of balance.
Darrell1 said:I think there is a lot of mis-information. The problem with a battery being out of balance and using a charger that does not balance is it is possible to overcharge some of the cells. A "dumb" charger just monitors the voltage of the entire battery, not each cell, so it is possible to overcharge some cells.
Once you have a battery that is out of balance, it is also possible to drain one cell too low which would also cause damage. Since everyone is using a balanced charger, there are no worries. With every charge, it makes sure all the cells are the same voltage when it is done. This occurs near the end of the charge as in the middle of the charge, it does not matter if they are out of balance as long as one cell does not get too high.
