How many 18650 batteries do I need for 1 kWh?
136
If you have, for example, 2Ah lithium ion 18650 battery cell then each of those stores 7.4Wh (3.7V*2Ah=7.4Wh) of energy and you need 136 of them (1000/7.4 ~ 136) for a 1kWh battery. 136 in parallel will give you a 1kWh battery with a nominal voltage of 3.7V.
