Use a voltmeter to measure the voltage of the assembled 7.4V battery pack. Charge the battery pack using a compatible 7.4V charger or one designed for two Li-ion/LiPo cells in series. Monitor the charging process and ensure the cells are balanced during charging. Part 6. How to charge a 7.4V battery?
The “7.4V” part of the name refers to the voltage, which is a combination of the individual cells inside the battery. Each cell in a LiPo battery typically has a nominal voltage of 3.7V. When two cells are connected in series (hence, “2S”), their voltages add up to 7.4V.
Part 1. What is a 7.4V LiPo battery? A 7.4V LiPo battery, also known as a 2S LiPo battery or a 7.4V LiPo battery pack, is a type of lithium polymer battery. The “7.4V” part of the name refers to the voltage, which is a combination of the individual cells inside the battery. Each cell in a LiPo battery typically has a nominal voltage of 3.7V.
The voltage range of a 7.4 V lithium battery is generally as follows: Nominal voltage: 7.4V. This is the voltage output by the battery under ideal conditions, usually marked on the battery. Full voltage: about 8.4V. When the battery is fully charged, the voltage will reach its highest value, generally around 8.4V. Low voltage: about 6V.
In our case we have a 7.4V Lithium battery pack, which is nothing but two 18650 cells of 3.7V each is connected in series (3.7V + 3.7V = 7.4V). This battery pack should be charged when the voltage reaches down to 6.4V (3.2V per cell) and can be charged upto 8.4V (4.2V per cell). Hence these values are already fixed for our battery pack.
The discharge voltage is the voltage level at which the cell operates while providing power. For li-ion cells, the typical voltage range during discharge is from 3.0 to 4.2 volts. It’s crucial to avoid letting the voltage drop below 3.0 volts, as over-discharging can lead to irreversible damage and significantly reduce the battery’s capacity.
