Please tell me about the capacity of lithium batteries connected in series and parallel

Capacity 35,000 mAh-55,000 mAh.

The purpose of parallel connection of lithium batteries is to increase capacity. Therefore, parallel charging of lithium batteries also has different design features compared to single-cell lithium batteries. charging current design and parallel battery design.

Once the batteries are connected in series, the voltages are added and the currents are equal. This increases the tension. When the batteries are connected in parallel, the voltage remains unchanged (the principle is that the batteries are similar). the voltages can be connected in parallel, otherwise the one with higher voltage will charge the one with lower voltage), it can be dangerous if the difference is too big), the current is equal to the sum of each battery, which can often be considered to increase the capacity of the battery and provide a greater current.

Precautions for using lithium batteries

Do not mix batteries and choose batteries with consistent performance. Replace all batteries when they are low. If used in series, use the same battery type. Pay attention to the polarity of the battery. If the polarity of a battery is reversed, it will reduce the voltage of the entire battery string instead of increasing it.

Keep battery connection points clean. When four batteries are connected in series, there are eight connection points (the connection point from the battery to the battery compartment and the connection point from the battery compartment to the next battery). Each connection point has a certain resistance. If multiple connection points are added, it may affect the performance of the entire battery.
