How to measure capacity of a Lithium-ion battery
eg if you have a 1 cell battery (Voc=~4.2V) of 1500 mAh capacity then. R = cells x 4000 / mAh = 1 x 4000/1500 = 2.666 ohm ~= 3 ohm or 3.3 ohm (std value) Use the next largest resistor than the value calculated. Up to Several times larger is OK BUT it will take proportionally longer. Resistor power rating: Resistor power = V^2/R = (4 x number …
