Batteries, despite being ever-common in our world, are modern marvels of science, capable of “storing” electricity via the clever composition of reactive chemicals in a specific arrangement. However, choosing the right batteries can be tricky, because the world of Batteries is complicated, and there are many different types available, with various capacities, charge and discharge rates, chemical compositions and internal resistances that all offer slightly different results.

Fortunately, we take the time and effort to research and source the best LiPo and Li-Ion Batteries for hobbyist applications, such as these Maxwell & Spark 18650 3.7V 2600mAh Rechargeable Li-Ion Cells, which offer impressive technical specifications compared to the slew of other options on the market. Designed in a similar fashion to the PANASONIC NCR18650PF Batteries, these batteries have a good capacity of 2600mAh, a powerful continuous discharge current rating of around 7.8A, as well as a low internal resistance of around 50mΩ or less.
