3 Cell Lipo Battery Storage Voltage

Since lipo batteries started becoming big in the rc hobby all sorts of processes and procedures for proper battery care have popped up.

3 cell lipo battery storage voltage.

Therefore battery voltage is often referred to as how many cells in the battery aka s. So a two cell 2s pack is 7 4v a three. Different battery companies mark their lipos in different ways but most people tend to refer to their batteries as 1s 2s 3s etc. Li ion cells marked as high voltage compatible if charged up to 4 35v have a comparable cycle life to standard 3 7 v cells.

As we know it s not right to storage a lipo battery with fully charged or fully discharged it can actually damage the battery. Therefore lipo batteries need to be discharged and stored with cell voltages near nominal at 3 8v. The benefit of charging at a maximum 4 35v voltage is an increase of about 10 in energy density when compared to charging a traditional 3 7v cell of the same size and weight to 4 2 v. Each cell in a standard lipo battery has a nominal voltage of 3 7v.

This is sometimes why you will hear people talk about a 2s battery pack it means that there are 2 cells in series. A standard 3 7v cell should never. Lipo batteries used in rc are made up of individual cells connected in series so the battery s voltage is the sum of the voltage of the cells. 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.

Voltage cell count. Don t fully discharge your lipo battery unless you plan on disposing of it. 1s 1 cell 3 7v 2s 2 cells 7 4v. Lipo battery voltage is specified by the number of cells in series.

For the 7 4v battery above that means that there are two cells in series which means the voltage gets added together. The proper lipo storage voltage is 3 8v per cell. As long as the voltage is 3 8v per cell store your batteries between 40 60 charge for best longevity. At no time during use should the voltage drop below 3 0v.

A lipo cell battery should never be discharged below 3 0v. Each cell has a nominal voltage 3 7 v. I know it may be tempting to get just a few more minutes out of your rc vehicle but lipo batteries have a low voltage per cell of 3 0v. A fully charged lipo voltage is 4 2v per cell hv lipo can be charged to 4 35v.
