- LRs came on the scene shortly after vapefest 2010 in Virginia;
- They were improperly marketed e.g requires high drain batteries of 420mAh or better;
- It should have read with a discharge capacity of 4A or better; and
- It is the mAh that folks are basing their needs on, not the battery's capacity to deliver current, and that is where the problem lies IMO.

A new day, a new way! - Vaping: Battery - FAQ
What is internal resistance in a battery and where does it come from?
Lithium-ion batteries lose capacity through cell oxidation (cholesterol), a process that occurs naturally during normal battery use and aging. As the battery ages, internal resistance (cholesterol) increases as well. This increase in cholesterol (internal resistance) leads to plaque build up and when sufficient build up occurs. This results in a plugged artery/battery or, a battery that can no longer deliver current sufficiently to meet the workload. Not dissimilar to someone having a heart condition having difficulty going up a flight of stairs.
Does internal resistance decrease the amount of usable energy in a battery?
Yes it does. It reduces the battery's overall charge capacity. Three imaginary sections of a battery consisting of available energy, empty zone and rock content. With use and age, the rock content grows.
I have heard a term stressing a battery. What, if any, effect does stressing a battery have?
The short answer is rapid ageing due the increase build up of cholesterol (or internal resistance), in this particular case caused by excessive work demands. These excessive work demands increase the creation of internal resistance (cholesterol) exponentially, leading to an increased plaque build up (the rock zone).
Is stressing a battery dangerous?
Yes, emphatically so.
What could be the results of a stressed/over-stressed battery?
In milder cases, the build up of plaque results in a plugged artery and possible heart failure, or in our case the battery will no longer hold a charge or deliver current.
In severe cases clogged arteries can lead to aneurisms and death. In our application, should the protection circuit fail, and we have a stressed battery, which translates to an over-current condition, the battery may vent or even explode.
