As a rule of thumb small li-ion or li-poly batteries can be charged and discharged at around 1C. "C" is a unit of measure for current equal to the cell capacity divided by one hour; so for a 200mAh battery, 1C is 200mA.
Occasionally lithium battery cells are marketed with just a C rating and not a maximum current rating. This can make it easier to compare the power level of battery cells of different capacities. As long as you know the capacity of the cell, you can use the C rate to quickly calculate the maximum current rating of the cell.
The capacity of a cell is probably the most critical factor, as it determines how much energy is available in the cell. The capacity of lithium battery cells is measured in amp-hours (Ah) or sometimes milliamp-hours (mAh) where 1 Ah = 1,000 mAh. Lithium battery cells can have anywhere from a few mAh to 100 Ah.
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.
The nominal voltage is distinguished from differen li ion battery models.For example, when a device is marked with”3.7V lithium-ion battery,” it’s referring to the nominal voltage of 18650 cells. When an 18650 battery is fully charged, its voltage reaches approximately 4.2V. It is the maximum safe voltage of standard 18650 cells.
The capacity of lithium battery cells is measured in amp-hours (Ah) or sometimes milliamp-hours (mAh) where 1 Ah = 1,000 mAh. Lithium battery cells can have anywhere from a few mAh to 100 Ah. Occasionally the unit watt-hour (Wh) will be listed on a cell instead of the amp-hour. Watt-hour is another unit of energy, but also consider voltage.
The maximum current a battery can safely provide is dictated by its discharge rate, which is linked to its ampere capacity. For a typical 18650 battery, the discharge rate could range between 15 to 30 amps. High-drain batteries intended for demanding applications can even exceed this range.
As a rule of thumb small li-ion or li-poly batteries can be charged and discharged at around 1C. "C" is a unit of measure for current equal to the cell capacity divided by one hour; so for a 200mAh battery, 1C is 200mA.
Power Output: Voltage also influences the power output of the battery. Higher voltage batteries can deliver more power, which is important for applications that require high power output, such as electric vehicles and power tools. However, LiFePO4 batteries have lower voltage compared to other lithium-ion chemistries, so they may require more cells in series to achieve the desired …
Maximum Discharge Rate: Maximum current the battery can supply safely. Varies, e.g., 1C to 5C for lithium-ion : Higher discharge rates reduce cycle life; C-rate indicates current relative to capacity (1C = 100% capacity in one hour). Temperature Range: Optimal operating and storage temperature to maintain performance.-20°C to 60°C (operating) Avoid …

Each 18650 cell can only hold a certain amount of material inside. So you usually must choose between the 18650 maximum capacity or a high current battery. Currently, most 18650 lithium batteries on the market have capacities between 2200-3500mAh. The 18650 lithium battery in this capacity range has the best stability and consistency.
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh ). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours).

2- Enter the battery voltage. It''ll be mentioned on the specs sheet of your battery. For example, 6v, 12v, 24, 48v etc. 3- Optional: Enter battery state of charge SoC: (If left empty the calculator will assume a 100% charged battery).Battery state of charge is the level of charge of an electric battery relative to its capacity.
When an 18650 battery is fully charged, its voltage reaches approximately 4.2V. It is the maximum safe voltage of standard 18650 cells. The discharge cutoff voltage, known as the low voltage limit, is around 2.0V to 2.5V for 18650 batteries. This voltage should be considered as "empty" and the 18650 batteries should be charged.
