looking at individual lifepo4 cells

[thepilot]

Looking at these cells to make a 12v battery for an rv....in the description it states that each cell is 3.2v 50ah. I know that I need 4 of these cells to make a 12v battery. What will the amp hours be at 12v? Do the amp hours increase with each cell that is added? Or do the amp hours stay at 50 even though there will be 4 cells?
thank you!!

LiFePO4 3.2v 50Ah Prismatic Cell Lithium Iron (Li-ion) Battery (1 Unit) | eBay

Cells: 1 Prismatic Cell. Each battery is a single cell, 3.2 volt battery. But are very easy to link together in series for 6v, 12v or 24v applications. So you're getting a great battery at closeout prices.

In series you add the volts, but the amps stay the same. In parallel you add the amps but the volts stays the same. So you will end up with a battery with paper specs of 12v 50ah.

Depends on the wiring, SAVPAA- Series Adds Volts, Parallel Adds Amps

Wiring the 4 cells in series will result in a pack that is 12V at 50ah

Wiring the same 4 cells in parallel will result in a pack that 3.2V at 200ah
