    18650 Batteries Internal Resistance Test...

    I am just a battery junkies and want to know the relationship between battery internal resistance and high drain battery.

    The statements, conclusions, and recommendations I make based on these tests are only my personal opinion.

    At first, it is said that a battery with low internal resistance delivers high current on demand. High resistance causes the battery to heat up and the voltage to drop.Which is from www.batteryuniveristy.com.

    Following are the test results:

    In general, all of the coil of big Watt e-cigarette box mod is sub-ohm,as the same level as the internal resistance, so the lower the internal resistance of batteries, then the lower internal resistance of the whole circuit, the higher the current will be improved, which make more smoking cloud. Besides, the lower the internal resistance of batteries, the higher working efficiency of the batteries (the less energy will be expended by the battery itself when used), and the higher effective using energy after charged.

    OK, what are we looking at?

    We all know E is increased when using cells with a lower IR. That is a given. You have pictures of various tests and numbers. The resistance is being measured and one would expect a change in #s there, but what is going on with V? What were the state of the batteries tested? Brand new fully charged (fresh off the charger), what kind of load was applied? In other words what was your measuring standard? What was the AH rating of the batteries etc...

    IMHO data totally inconclusive without knowing the test parameters. Furthermore, not all batteries will age the same. In some cells IR increases quicker than others as the rock content increases (Battery University). As rock content increases so does IR, which becomes a dog chasing its tail, the two become exponential. To me from the data viewed it would seem that you are pushing the Tesiyi cell (lowest IR) without specifying the specs of each battery, you simply cannot draw any conclusion.

    In the day (before all these cells flooded the market) the consumer had few choices. We had AW and the *** Fire series, then came Efest. AW won all tests with flying colours but, they were expensive. Batteries in general have come down in prices. The Europeans came across the Efest battery that for all intent and purpose possessed the same specs (test results) as the AW. At roughly 1/2 the cost it was a no brainer it was going to be a hit. Short strokes... it was great out the gate but failed in the stretch where, one was accustomed to see battery wane @ around the 8M mark with AW, battery wane would occur around 4M and some @ 3M. Not everyone had a battery analyser and perceptions could be misleading. That being said, folks did conduct tests against each cell and the results were in the pudding, no longer speculation, but facts backed up with data. The build materials Efest employed were not the same quality as AW. Yes the battery did cost 1/2 as much, well not really 1/2 more like 2/3s but, only lasted 1/2 as long due to rock content increasing IR, decreasing the overall battery lifespan.

    See where I am going with this?

    Thanks for your replying. It is our fault to state those. All the batteries are fresh and Sigelei 35A 2500mAh, Samsung 25R 35A 2500mAh, Tesiyi 40A 2600mAh, LG HE2 35A 2500mAh, Efest 35A 2900mAh, AWT 40A 3000mAh. And all the tests are in 3.7-4.2 voltage. And just testing the relationship between battery internal resistance and high drain battery.
