Power versus Energy Cells

Comparing power versus energy cells we see there are some fundamental differences. A high energy cell will have better volumetric and gravimetric energy density at the expense of the ability to deliver a high current. The power cell will have a low internal resistance and will be optimised to deliver current over energy density. Teardown … Read more

Cells in Series

When connecting cells in series the negative terminal of the first cell is connected to the positive terminal of the second cell. The negative terminal of the second cell is connected to the positive terminal of the third cell. This continues until we reach the total number of cells required in series. The nominal voltage … Read more

Battery Capacity

The battery capacity is the current capacity of the battery and is expressed in Ampere-hours, abbreviated Ah. Battery capacity is expressed in ampere-hours. Battery capacity is effected by: Under well defined conditions this is often referred to as the Rated Capacity as the battery capacity is likely to be different under different temperature, discharge rates … Read more
