How many Mah is a 4 cell battery?

For your 4-cell pack the 2620mAh is the rating of each cell, but if they made an 11.1v 6-cell or 14.8 8-cell version with the same cells those would be rated 5240mAh (2x as the additional batteries would be in parallel).

How many Mah does a 4 volt battery have?

If the total volts for 4 batteries is 14.4 volts then mAh of each battery is 3200. Thus, the total 4 batteries mAh is calculated or the mAh remains constantly if we add several batteries by maintaining the volt constantly. Where did 3200 come from? There's no information here that leads to such a number. Tl;DR: see last sentence.

How much lithium ion does a battery provide?

(2024: A LiIon cell provides about 12 Wh per gram of 'metallic Lithium equivalent' - or ABOUT 0.8g of Li by weight in a 10 Wh LiIon 18650 cell.). Two batteries of the same nominal capacity should have similar weights. I'd guesstimate that a 10% difference may be due to happenstance and construction, but beyond that I'd be suspicious.

How much does a lithium ion battery weigh?

Lithium-ion batteries charge faster, last longer and have a higher power density for more battery life in a lighter package. The weight of a Lithium-ion battery depends on the size, chemistry, and the amount of energy it holds. A typical cell weighs about 30-40 grams. Cells are packaged together to make a battery pack for a device.

How many Mah does a battery pack have?

The resulting pack has a 5,200 mAh rating and a nominal voltage of 10.8 V. If you wired the six Li-ion cells differently, say in 2S3P (two cells in series, and three of those sets in parallel), you’d get a battery pack with a 7,800 mAh rating, albeit at 7.2 V.

What is a 4 cell lithium pack?

There's no difference. A 4-cell, 14.8V lithium pack consists of four 3.7V lithium cells connected in series. Since they're connected in series, the same current flows through all the cells. So when you've drawn some number of mAh out of the pack, you've drawn that same amount of mAh from each cell as well.
