So I have been looking on amazon at the 1000w kits avaliable for cheap, and through some research I have come to understand that you can easily put 2000-3000w in them for short periods at a time. What is the easiest way to do this? I heard you can probably use a 60v battery with the included controller, though this seems very uncertain and risky. Would it be better buying a 72v 40 amp controller? If so, which one? I am limited to amazon .de as I live in Europe.
Battery wise, the ones available on amazon don't seem to ship here and are very sketchy looking, doubt they can output much current. The ones I can get here are way too expensive, so the best option seems to be assembling my own battery. I can get 60 Samsung INR18650-25R 2500mAh for $200, 80 for $250 or 100 for $300. Would a 20s 2 or 3p work for the 40 amp controller? Or would I need at least 4p (as in 10 amps per cell in parallell)? Might it be worth having a lower voltage for allowing higher amperage with the same amount of cells? I can also get 80 Samsung INR18650-35E 3400mAh 10.5A for $300, would this be a good alternative?
Thanks in advance!
