What is current and voltage additive?
These terms refer to the electrical arrangement of several cells when forming a battery pack. Cells that are stacked end to end in series (+ to ) create a voltage addition effect. Meaning that, the total voltage of the joined pack is equal to the number of cells multiplied by the voltage of each cell. (Example: 3.7 Volts x 4 Cells = 14.8 V) On the inverse, if each cell is stacked side by side in parallel (+ to +) a current addition effect is created. In this case the overall voltage of the battery pack will be the same value as one cell, but now the battery pack will be able to supply a higher current which is a multiple of the number of stacked cells. (Example: 2500 mAh x 4 Cells = 10000 mAh) Different types of lights use different voltages; this is why battery packs are often connected in various combinations. When comparing battery packs you must remember that both the mAh rating and voltage of the pack is important. In our two examples one may falsely concluded that the 10000 mAh
