Building 18650 Battery Pack
Looking at different battery cells and voltages 3.7 & 3.6 I'd had an idea just to buy a tesla battery module that is 24v came up with this as locally supplied 3kwh (module) This being 3kwh would have been ideal.
But one of the challenges is building the battery which i want to do. However I am going to have to do a lot more hunting for batteries as to build a 2kwh battery 300cells costs nearly £700 including tax
Samsung 25R 2500mah
Samsung 22P 2200mah
for my info voltage of cell * the amount of parallel cells 2000 * 20 = 40Ah
24v = 3.6 * 7cells
1 kwh = 140 cells on 24volt battery
