Energy measured in wh watt hours the energy is the total amount of work that a battery can do.
3 cell lipo fully charged voltage.
And all of this adds up the more often you let your lipo battery sit around fully charged the worse it will get.
Only if the charger has a switching converter can it charge from a lower voltage.
Lipo batteries are fully charged when they reach 4 2v cell and their minimum safe charge as we will discuss in detail later is 3 0v cell.
The nominal voltage of 1 cell lipo batteries is 3 7 v.
Ideally you never want to go below 3 2v per cell to maintain a healthy battery.
A lipo cell battery should never be discharged below 3 0v.
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.
For example almost all lithium polymer batteries are 3 7v or 4 2v batteries.
Cut off voltage the voltage at which a battery is considered discharged.
It is not however the full charge voltage of the cell.
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.
A lipo cell nominal voltage is 3 7v.
In practice at least 14 v would be needed.
A battery sitting at 60 degrees celsius will lose 40 of its capacity in just 3 months.
Never discharge a lipo battery below 3 0v per cell.
3 7v is pretty much in the middle and that is the nominal charge of the cell.
Depending on the design and chemistry of your lithium cell you may see them sold under different nominal voltages.
This is the voltage you will find on battery labels.
Up to c 1 rate up to 3 6 v then constant voltage at 3 6 v until i c 24.
So a linear 3 cell charged would need almost 13 v and that is excluding some voltage drop for the charging circuit.
The proper lipo storage voltage is 3 8v per cell.
2 9v per cell and lower is causing permanent damage.
Typically a full charge is 4 2v per cell.
Never overcharge a lipo battery.
A fully charged lipo voltage is 4 2v per cell hv lipo can be charged to 4 35v.
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.
A battery sitting at room temperature fully charged will loose about 20 of its capacity in a year.
Never trickle charge a lipo battery.
A fully charged cell has a voltage of 4 1 to 4 3 v depends on the cell.
