Translations:Lithium-ion battery/3/en

The design of lithium-ion batteries and the presence of a BMS systems means that the batteries are designed to function at a set nominal voltage and are not intended to be wired in series like is done with lead acid batteries. They are sold in 12 V, 24 V, and 48 V nominal voltages that can be wired in parallel to achieve the desired Ah or kWh capacity. One of the advantages of the BMS systems that accompany each battery is that proper charging is ensured for all batteries connected in parallel meaning that there is typically no limited to the number of batteries that can be put in parallel like exists with lead acid batteries (it is best to limit the number of lead acid batteries in parallel to no more than three strings to ensure proper charging).
