6 FAQs about [Lithium battery pack has an extra wire]

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 material is used to connect lithium ion batteries?

Nickel is the preferred conductor to connect lithium-ion battery cells together. Nickel strip is the most common material used in lithium-ion battery construction because it is easy to spot weld and has excellent anti-corrosive properties while having a relatively low cost. 99.6% pure nickel strip in a variety of lengths, widths, and thicknesses.

What is a lithium ion battery in parallel?

Lithium ion batteries in parallelis to increase the amp hours of a battery (i.e. how long the battery will run on a single charge). For example if you connect two of our 12 V, 10 Ah batteries in parallel you will create one battery that has 12 Volts and 20 Amp-hours.

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 amps does a lithium ion battery need?

Watts divided by volts equals amps. So, that means your circuit will require 41.6 amps. Lithium-ion batteries can store quite a bit of energy. To be able to access that energy, a conductor must be used to connect the cells together in the best way for a given project. Nickel is the preferred conductor to connect lithium-ion battery cells together.

What's inside a single-cell Li+ battery pack?

If you want to explore what’s inside single-cell Li+ battery packs, look-up bq27000 gas gauge IC and associated application notes. Could be a good starting point. Some packs have 4 terminals: positive, negative, SDA, SCL. The latter 2 lines are I2C or SMBus. Look up the bq27200 gas gauge IC (shares datasheet with bq27000).
