I''m trying to figure out how to build an external battery pack for a laptop, plugging into its 19V DC input. In a previous question I learned that I probably want to go for 5 lithium cells in order to closely match the 19V input expected by my laptop. But even if such a battery pack nominally provides 18.5V, it can peak at 21V and go all the way down to 14V and below.

Putting cells in parallel adds up their capacity and max output current. Putting batteries in series adds up their voltage. The cells are 4.2V 3Ah cells. So our battery is a 12V, 6Ah battery, with

A: 3.7V is a rated voltage of lithium battery and the max charging voltage is 4.2V. The nominal voltages of 3.7V and 4.2V are equivalent when it comes to size and capacity.3.7V battery can replace a 4.2V battery. Q:
To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
Battery current (Amperes) is "FLOW RATE". The maximum amount of current (Amps) a battery can source is limited by it's chemical properties. Its typically INVERSELY proportional to the cell capacity (Amp-Hours). Yes, the higher the Amp-Hours, the lower the maximum Amps the battery can supply. POWER is measured in watts, 1 Watt = 1 Volt x 1 Amp.
Maximum battery POWER OUTPUT is dependent on it's maximum current output and it's voltage. What is 18650, 21700? These are cell sizes, 18650 means the cell is 18 mm in diameter and 65 mm long. 21700 means it's 21 mm in diameter and 70 mm long.
Putting batteries in series adds up their voltage. The cells are 4.2V 3Ah cells. So our battery is a 12V, 6Ah battery, with energy of 74 Watt-hours, maximum recommended current output of 30 Amps and maximum recommended power output of 12V x 30 A = 360 Watts. How does it compare to a M12 4Ah battery?
So our battery is a 12V, 6Ah battery, with energy of 74 Watt-hours, maximum recommended current output of 30 Amps and maximum recommended power output of 12V x 30 A = 360 Watts. How does it compare to a M12 4Ah battery? The 4Ah battery uses 2 banks of three 2 Ah, 20A cells. Let's write out the specs: AHA!
A 2 Ah, 18 volt battery will have more stored energy than a 2 Ah, 12 volt battery. 2x18 = 36Wh versus 2x12 = 24 Wh A 6 Ah 12v battery has more stored energy than a 1.5 Ah 18 volt battery. So for example an M12 hackzall with a 6AH 12 volt battery will yield more cuts than a 18V hackzall with a 18v 1.5 Ah battery.
