Why does this battery have four wires : r/AskElectronics
Why does this battery have four wires 2 of them obviously would be positive and negative terminals i thought maybe another would be ground but do you have a ground connection for a battery pack? Does that make sense? If it''s a 3S lithium pack, the middle two (yellow/white) may be for cell balancing.

Does a li-po/li-ion battery that has a pcm and ntc thermistor need 3 wires?
The white wire on a 3 wire battery should be left unconnected when that battery is used with a 2 wire charging circuit, because that kind of charger doesn''t look at battery temperature. However a 2 wire battery connected to a three wire charger should have the thermistor connection on the charger terminated, usually with 10Kohm, to ground.

Why are there three wires from the battery?
Do a forming charge for the first one, that''s a slow one with the charger supplied with the radio gear to charge the Tx and Rx and usually takes about 10-14 hrs to charge fully, for all the charges after that I would set the rate at no more than 1C, that''s the capacity of the battery pack divided by 1000 so your 255mAh pack would require a .2A Charge, the forming charge

Why do Lipo''s have 2 plugs and what is
Lipos have a really sharp voltage drop off when they get fully discharged and it doesn''t take going much past this drop off to damage a cell. If the cells aren''t balanced, one cell can fall into this danger zone while the entire pack still reads safe.

What are the three wires in a lithium polymer battery?
This article delves into the functions and significance of these three wires in a lithium polymer battery. Firstly, let's understand the basic structure of a lithium polymer battery, Even if it is rechargeable ultra thin battery, It comprises two electrodes – a positive (cathode) and a negative (anode) – separated by a polymer electrolyte.
How do you know if a lithium battery is protected?
A 4s lithium battery has 0, 3.7, 7.4, 11.1, 14.8, and 5 different potentials. If it is a protected version, the two red and black wires should be internally shorted. The white wire is the flag of the protection chip. It is a high battery voltage when it is protected and a low voltage when it is not.
How many terminals does a rechargeable Li-ion battery have?
Rechargeable Li-ion batteries usually have three terminals. I think one must let electrons in and one must let electrons out, so is the third terminal allowing some other type of particle to nip around? It's a thermistor terminal to monitor the temperature of the battery. You don't want your electrons nipping about too energetically do you. Thanks!
Which wire carries the current from a battery to the device?
This wire carries the current from the battery to the device being powered. The positive wire ensures that the flow of electrons is directed correctly, maintaining the electrical circuit's integrity. The second wire, often designated as the negative or black wire, represents the battery's negative terminal.
What is inside a Li+ battery pack?
In mobile phones, some Li+ battery packs have 3 terminals. Two possibilities: positive, negative, 1-wire bus. The latter is a digital communication bus that’s connected to a gas gauge IC inside the pack. If you want to explore what’s inside single-cell Li+ battery packs, look-up bq27000 gas gauge IC and associated application notes.
What if my battery does not have a protective board?
If a lithium battery does not have a protective board, the three wires are: the red wire is the positive pole, the black wire is the negative pole, and the other color wires do not serve the function of providing the product motherboard to monitor the voltage of the lithium battery. Instead, these batteries should be handled with extra caution due to the risk of overcharging or deep discharging.
