battery pack is then assembled by connecting modules together, again either in series or parallel. • Battery Classifications – Not all batteries are created equal, even batteries of the same chemistry. The main trade-off in battery development is between power and energy: batteries can be either high-power or high-energy, but not both.
Each battery chemistry, such as lithium-ion, nickel-metal hydride, or lead-acid, has unique characteristics in terms of voltage output, charging cycles, temperature tolerance, and discharge rates. Using a different chemistry can lead to issues like reduced performance, potential damage to the device, and in extreme cases, safety hazards like overheating or leakage.
