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.
If it is a 4s lithium battery, it is 0, 3.7, 7.4, 11.1, 14.8, 5 different potentials. If it is a protected version, the red two wires and the black two wires should be internally short-circuited, and the two wires are used to increase the current. White is the flag bit of the protection chip.
1) If your battery does not have a protective plate, the three wires are: the red wire is the positive pole, the black wire is the negative pole, and the other color wires are the middle pole of the battery.
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?
Its common for a LiPO battery pack to have a tap in between every cell, so 3 wires makes sense for a 2S pack. Assuming the color codes are typical, where black is 0V and the Red is the full output, check with a voltmeter I'll bet you'll see about 3.5V between the black and white, and about 7V between the black and red.
A LiPo cell has a nominal voltage of 3.7V. For the 7.4V battery above, that means that there are two cells in series (which means the voltage gets added together). This is sometimes why you …
As Fredrick said, for a tournament saber, a 7.4V battery pack bundled with a buck converter does makes sense. And if you want to make a charging pack, it also helps. …
If your battery does not have a protective plate, the three wires are: the red wire is the positive pole, the black wire is the negative pole, and the other color wires are the middle pole of the battery.
White wire is thermistor terminal which is needed for battery temperature sensing during fast charging. You should measure white wire voltage against black and red. …
