You need two cells rather than one (double the size), then electronics that handle 5V to 3.3V are plenty, cheap and small. 7.4V needs a down voltage regulator. Last, charging is a thing. First of all, there is no such thing as a 7.4v battery, only 7.4v battery packs made from two 3.7v cells hooked up in series.
A 7.4V lithium battery has a nominal voltage of 7.4 volts. It’s commonly used in devices requiring more power than a single cell can provide. These batteries are typically made up of two 3.7V cells connected in series. The voltage of a 7.4 V lithium battery will change under different conditions.
Full voltage: about 8.4V. When the battery is fully charged, the voltage will reach its highest value, generally around 8.4V. Low voltage: about 6V. When the battery is exhausted, the voltage will drop to its lowest value, generally around 6V.
3.7V batteries are commonly used in small, portable electronic devices like smartphones, cameras, and vaping devices. 7.4V batteries are often used in larger, power-hungry devices like power tools, drones, and some RC vehicles, where the higher voltage and energy capacity are beneficial.
A 7.4V LiPo battery is a specific type of rechargeable battery that uses lithium-polymer chemistry. LiPo batteries are known for their high energy density, compact size, and flexibility in shape. The 7.4V nominal voltage is typically achieved by connecting two 3.7V LiPo cells in series.
If you know that the battery voltage is 18 V and current is 6 A, you can that the wattage will be 108 W with the following calculation: How to calculate power? If you are still not sure how to calculate power with the provided formulas, or simply want to save your time, you can use our Ohm's Law calculator.

The charging time for a 7.4 volt battery varies depending on its capacity and the charger''s output current. Generally, a 7.4 volt battery with a capacity of 2000mAh can take 2-3 hours to charge fully using a 1A charger.
To find the input current required to achieve a certain motor output power, use the following equation. I (A) = P (kW) × 1,000 / V (V) × η. Thus, the current I in amps is equal to the power P …
It''s not clear how much current the shield could draw with the volume turned up to maximum. The other option is to use a dc-dc "buck" converter to turn the 7.4V into 5V and …
