The world is shifting away from fossil fuels and will one day become fully electric. In the present world, Lithium-ion is the most promising chemistry of all batteries. It is one of the most mature Li-ion formats available, is produced in high volume, and enjoys a low cost per Wh. If you enjoy my work here on Instructables, consider joining my Patreon , it will be a great help for me to make more interesting projects in the future. The 18mm diameter and 65mm length battery is a size classification of lithium-ion batteries. It is the same shape, but a bit larger than a AA battery. AA batteries, by comparison, are sometimes called batteries because they have a 14mm diameter and 50mm height. Earlier I have made a Solar Power Generator which is working really nice till now. But the main problem is its weight, it is really heavy. The main weight of the Solar Generator is due to the heavy lead-acid battery inside it. The fundamental is very simple: Just to combined the number of cells in series and parallel to make a bigger pack and finally to ensue safety adding a BMS to it.
