Following the 18650 capacity tester build part1 & part2

The 18650 Cell belongs to the Lithium Ion type chemistry, very high care has to be taken while using it. This includes while both charging and discharging the batteries. While discharging the battery, care should be taken that we never consume more current than the  C rating and also the battery should never be discharged below 3.0V. Normally a circuit will be employed to monitor the discharge current and under voltage value to cut off the battery from the load if anything goes wrong. Also care should be taken that the battery never experiences a short circuit or reverse polarity. 

mAh is a measure of battery capacity, and it utilizes all three concepts (electric charge, current, and time) to estimate how much electricity the battery can hold. For example, a capacity rating of 1,000mAh on a battery means that once fully charged, it can sustain an electric flow of 1,000mA for one hour.

The ENE is Watt hours 

Wh is short for Watt Hours.

The energy capacity or capacity to do useful work stored in the battery.

The maximum electric current a battery can output depends on the battery's structure and is measured as the discharge rating.

We are using different methods to better understand the discharge and capacity of LiPo batteries

This is some actual testing now we have figured out a system. Battery #2

After 1amp discharge.  The dl24 is setup to stop at 2.7. the batteries bounce back after removing them to 3.12

Beginning Test 2 on battery #2
