I’m building Tw200 Yamaha with a 15-20 hp motor and would like about 30 mile range on a 72 volt system can anybody recommend what and how many cells On a vruzened 2.1
I'm running these numbers rough. 38120's nominally operate at 3.3V. So 22 to 23 cells are needed for 72V nominal. Capacity is 9.8 Ah minimum each. So 9.8 Ah * 23 * 3.3V cells gives a capacity of 743.8 WH.Could I get 30-50 mile range on a 38120 pack at 72 volts. I would need over 23 cells, correct.
