Typically a full charge is 4 2v per cell.
3 cell lipo fully charged voltage.
Only if the charger has a switching converter can it charge from a lower voltage.
A battery sitting at room temperature fully charged will loose about 20 of its capacity in a year.
A fully charged lipo voltage is 4 2v per cell hv lipo can be charged to 4 35v.
What this means is that the maximum voltage of the cell is 4 2v and that the nominal average voltage is 3 7v as the battery is used the voltage will drop lower and lower until the minimum which.

A fully charged cell has a voltage of 4 1 to 4 3 v depends on the cell.
Cut off voltage the voltage at which a battery is considered discharged.
A battery sitting at 60 degrees celsius will lose 40 of its capacity in just 3 months.
Never overcharge a lipo battery.
Never discharge a lipo battery below 3 0v per cell.
Up to c 1 rate up to 3 6 v then constant voltage at 3 6 v until i c 24.
3 7v is pretty much in the middle and that is the nominal charge of the cell.
A lipo cell nominal voltage is 3 7v.
A lipo cell battery should never be discharged below 3 0v.
So a linear 3 cell charged would need almost 13 v and that is excluding some voltage drop for the charging circuit.
Never trickle charge a lipo battery.
2 9v per cell and lower is causing permanent damage.
This is the voltage you will find on battery labels.
Depending on the design and chemistry of your lithium cell you may see them sold under different nominal voltages.
Since lipo batteries started becoming big in the rc hobby all sorts of processes and procedures for proper battery care have popped up.
In practice at least 14 v would be needed.
The proper lipo storage voltage is 3 8v per cell.
It is not however the full charge voltage of the cell.
And all of this adds up the more often you let your lipo battery sit around fully charged the worse it will get.
Energy measured in wh watt hours the energy is the total amount of work that a battery can do.
According to one manufacturer lithium iron phosphate batteries in an electric car can be charged at a fast charging station to 80 within 15 minutes and 100 within 40 minutes.
For example almost all lithium polymer batteries are 3 7v or 4 2v batteries.
Ideally you never want to go below 3 2v per cell to maintain a healthy battery.
The one i d like to talk about today is the process of always charging your lipo batteries to a storage charge voltage of 3 8v per cell before packing them away after a day of flying.
