A 18 V 4 Ah battery contains 10 cells. Does that mean that a typical 18 V 4 Ah battery can theoretically provide the tool the equivalent of 3600 watt of power? (10 * 20 A * 18 V = 3600 W) No.
As you can see the two batteries are connected in series: the minus and plus terminals are connected together. You have created a 24V50 battery : 24V (due to series connection) with 50Ah capacity (number of Amps remains the same). If we measure the capacity in Watt-hours, the total capacity is now 24 x 50 = 1200 Wh.
Most batteries have a specific voltage rating, such as 1.5 volts for a standard AA battery. Understanding the voltage of a battery is important when determining if it is compatible with your device. The internal resistance of a battery affects its ability to deliver power efficiently.
For example, a 12V100 (a 12 volt battery with a capacity of 100Ah) has a capacity of 12 x 100 = 1200Wh. A 24V50Ah battery has a capacity of 24 x 50 = 1200Wh. So these batteries have the same capacity, only one works on 12 volts and the other on 24 volts. In practice you will notice that these batteries will be around the same dimensions and weight.
Let’s say you want to buy a 12V lithium battery to power some 12V LED lights. According to the product label on the LED lights, they use 2 amps. You want to run them for up to 5 hours at a time. The brand of lithium battery you’re looking at has a recommended depth of discharge of 80-100%.
For example, if a battery has a rating of 10 Ah, it can deliver a current of 1 amp for 10 hours or 2 amps for 5 hours. However, it’s worth noting that the actual capacity of a battery may vary depending on various factors, such as temperature and load conditions.

So now we use the above formula to calculate the current (amps) that the inverter will take from the battery. Power = Amps x Volts 110 watts = amps x 12 Therefore amps (every second, every hour, same thing; it''s continuous) = 110/12 = 9.16 amps. So at any moment, the inverter will need to draw 9.16 amps from the battery. If you need to power the Surface for one …
