Cell balancing and its importance
A Lithium LFP battery is composed of several cells connected in series, each delivering a nominal voltage in volts.
The initial balancing of the batteries is crucial for the health of your accumulators.
To know how many units you need to integrate in your basket, simply add up the energies of your batteries (1000 Wh = 1kWh). If in doubt, do not hesitate to contact us.
A lithium cell in an OLENERGIES battery has a nominal voltage of 3.25 Volts, but in many applications such as electric vehicles, drones, portable electronics need a higher voltage than this nominal voltage. This is why several cells are assembled in series to form a higher voltage battery pack.
When batteries are combined in series, the voltage value is added together. For example, when four 3.25V lithium cells are connected in series, the output voltage of the battery will be 13.00V.
Conversely, when cells are connected in parallel, the storage capacities (in Ah) are added together (but not the voltage).
Connecting several cells in series is like harnessing horses to a carriage. Only if all the horses move at the same speed, the carriage benefits from maximum efficiency. In a four-horse team, if one horse slows down, the other three must also reduce their speed, which decreases the overall efficiency. If one horse runs faster, eventually it will injure itself pulling the load of the other three horses. Similarly, when four cells are connected in series, the voltage values of all cells must be equal for the battery to have maximum efficiency. The method of keeping all cell voltages equal is called balancing.
Performing a very fine balancing of the batteries before use is the ideal practice. Trust us with this tedious operation, we have the best equipment available for perfect balancing which will ensure maximum performance and life of your batteries.
