For making the battery pack we require a 4S 40A BMS module, 4 Li-ion cells, nickel strip, DC female barrel jack, and cell connecting brackets. Apart from these, we will also connect a voltmeter, and a bulb to show the pack in operations, which will be connected through a switch.
Designing the Battery Pack!! To test the feature of the BMS we will require to connect all the cells in series to make a 4s battery and connect the BMS with this 4S battery. For making the battery pack we require a 4S 40A BMS module, 4 Li-ion cells, nickel strip, DC female barrel jack, and cell connecting brackets.
To make a battery pack, the first step is to know the nominal voltage of a cell. The cells selected by us have a nominal voltage of 3.7Volts while the charge voltage is 4.2V. So, in order to make a 12 V pack, we require 3 cells connected in series. The image of cells we used is shown below We are selecting a 3.7V battery with a capacity of 1200mAh.
When connecting batteries in series, the general advice is to use batteries of the same ratings and the same make and model in order to minimize differences in exact voltage and amperage. Note, we say ‘minimize’, because even batteries coming off the same production line can vary slightly in these measurements. Another factor is battery age.
Li-ion cells are increasingly used as battery packs for many applications due to their high energy density and rechargeable characteristics. However, we must link a Li-ion cell with a BMS to safeguard the circuit from being destroyed or reducing the cell's life.
There are two ways to wire batteries together, parallel and series. The illustrations below show how these set wiring variations can produce different voltage and amp hour outputs. In the graphics we’ve used sealed lead acid batteries but the concepts of how units are connected is true of all battery types.
