If you are looking to build safe-high performance battery packs, then you are going to need to know how to choose a BMS for lithium batteries. The primary job of a BMS is to prevent overloading the battery cells. So, for this to be effective, the maximum rating on the BMS should be greater than the maximum amperage rating of the battery.
To calculate the capacity of a lithium-ion battery pack, follow these steps: Determine the Capacity of Individual Cells: Each 18650 cell has a specific capacity, usually between 2,500mAh (2.5Ah) and 3,500mAh (3.5Ah). Identify the Parallel Configuration: Count the number of cells connected in parallel.
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 .
When charging a lithium-ion battery, a high voltage is applied across many sets of lithium-ion cells in series. If any one of the cell groups reaches the maximum charge voltage of a lithium-ion battery (4.2 volts), then the charge MOSFETs will be switched off to prevent overcharging the battery cells.
Battery capacity is measured in ampere-hours (Ah) and indicates how much charge a battery can hold. To calculate the capacity of a lithium-ion battery pack, follow these steps: Determine the Capacity of Individual Cells: Each 18650 cell has a specific capacity, usually between 2,500mAh (2.5Ah) and 3,500mAh (3.5Ah).

It''s crucial to ensure your charge controller is ...
Maximum discharge current : 1C. That means that it is rated to provide 250mA of current. As always, voltage can be raised by putting cells in series (but watch out for balancing issues), and current can be raised by putting cells in parallel. If both must be raised then a full array of cells must be used.
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. Example: common 402025 150mAh battery from Adafruit: quick charge 1C, maximum continuous discharge 1C.
