Capacity is a measure of the amount of energy a battery can store. It is typically measured in Amp-Hours (Ah) or milliamp hours (mAh). The higher the capacity, the longer you can run devices on your battery before recharging. Capacity is also sometimes referred to as C-Rating, with each C rating representing 1/1000th of the Amp-Hours …
The formula for determining the energy capacity of a lithium battery is: Energy Capacity (Wh) = Voltage (V) x Amp-Hours (Ah) For example, if a lithium battery has a voltage of 11.1V and an amp-hour rating of 3,500mAh, its energy capacity would be: Energy Capacity (Wh) = 11.1V x 3.5Ah = 38.85Wh.
Here''s how you can check the voltage of a lithium battery with a multimeter: 1. Set your multimeter to the "DC Voltage" setting. 2. Connect the red lead from your multimeter to the positive terminal of your lithium battery. 3. Connect the black lead from your multimeter to the negative terminal of your lithium 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 …
