Why is a LiPo battery dangerous?
The reason is that when a LiPo is brought below ~3.7V/cell, its internal resistance to taking on a charge begins to increase, some of which is permanent. Below ~3.0V/cell the damage becomes significant enough to care about. Below ~2.5V/cell, most manufacturers of LiPo chargers have said that the battery is too dangerous to be recharged.
Can a smart charger charge at 0.1A?
Note that although some smart chargers can charge at currents as low as 0.05A, many cannot charge at a rate lower than 0.1A. If you cannot set your charger to charge at a current as low as you'd like, simply choose its lowest setting possible, and carefully monitor the battery during the charge.
Can a LiPo catch on fire?
During a reasonable or slow discharge, however, LiPos will not catch on fire, even if discharged all the way down to 0V/cell. It is the *recharge* phase that would cause a fully discharged LiPo to catch on fire, not the discharge phase. The reason is that when a LiPo is brought below ~3.7V/cell, its internal resistance to taking on ...
Can you charge a LiPo battery below 2.5V?
LiPo batteries should never be discharged below 3.0V/cell, or it may permanently damage them. Many chargers don' t even allow you to charge a LiPo battery below 2.5V/cell. So, if you accidentally run your plane/car too long, you don't have your low voltage cutoff set properly in the ESC (Electronic Speed Controller), ...
Can you leave a NiMH battery unattended?
You should not leave them unattended because the NiMh/NiCad end-of-charge detection method is not compatible with Lithium based batteries, and if left on the charger until full, the end-of-charge state will never be detected and the LiPo battery will be overcharged until it (likely) catches fire and destroys itself.
