    Tested at 10A-25A constant current but no pulsed current tests due to the one FullyMax battery pack I purchased getting damaged. I am ordering two more and will be pulse testing them. These batteries were purchased by me and used only for testing thanks to the incredible donations many of you made.


    Disclaimer
    The statements, conclusions, and recommendations I make based on these tests are only my personal opinion. Carefully research any battery you are considering using before purchasing.

    Testing batteries at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved and how to minimize them. My safety precautions are the ones I have elected to take and you should not assume they will protect you if you attempt to do any testing. Do the research and create your own testing methods and safety precautions.


    Bottom Line
    The FullyMax 10Wh/900mAh battery pack delivers more energy (Wh) than the Samsung 25R or LG HG2. It beats the HG2 by about 9%-24% and the 25R by about 23%-33%, depending on the discharge current level.

    The different voltages make plotting everything together difficult. See the individual Wh discharge graphs below for more detailed information.

    Question. Was this test done with 3 Samsung or LG 18650 batteries considering that the Li-Po pack has 3 internal cells?

    I ask because I have a Wismec Reuleaux DNA 200 on the way and I'm curious as how the 3 18650's would stack up against the Li-Po. You weren't clear if you used 1 18650 or 3.

    I've had the Hana DNA 200 with the Li-Po 900mAh pack and I was really disappointed in the battery life. I did get a loaner Wismec Reuleaux DNA 200 and the battery life was considerably longer. I was sold on the performance and mine should be arriving tomorrow.

    It was done with individual 18650's. I could have made that clearer, sorry for the confusion. The "Watt-hour discharges of the individual batteries" section heading does at least indicate that those results are for single 18650 batteries. :)

    Three HG2's should last about 2-1/2 times longer than a single 900mAh 3S LiPo pack.

    Yea, 3000mAh vs 900mAh makes a huge difference! I think you'll be happy with the battery life of the Reuleaux.

    Thank you for clarifying that. The Reuleaux arrived just as I was leaving for work. I tossed some mixed batteries (same exact batteries just married in pairs for other boxes) until my Samsung 30q's arrive later this week. (got a better deal on them vs the HG2)

    I've vaped a tank full with a TFV4 and the N2 no air coils, the battery indicator hasn't even budged running at 600°F 100w. I'm more than happy. Not to mention that I don't have to drag my charger (LUC S2 or BT-C3400) around in the semi with me. The 2.1a USB adapter seems to work just fine and hasn't gotten warm charging.

    I've visited Orbtronic's Facebook page and I noticed a post saying "Sony VCT6 coming soon". I was curious if you've heard of any such rumors? I would imagine with LG and Samsung releasing newer batteries recently that Sony is about due to update their batteries for sake of competition.

    There are a bunch of verrrry interesting new batteries becoming available to vapers! The HB4 was the first and it ended up being king of the hill. The others I can't talk about until they arrive but I'm really looking forward to testing them!

    Depends on what power levels you run at, which determines the current being drawn from the batteries.

    Max Amps = Max Wattage / Min Battery Voltage

    Min Battery Voltage = 9.0V for the DNA200.

    When you calculate the max current you can then look up the Wh the HG2 delivers at that current level by using the small table in the OP.

    Cdr of the vtc5 is 20 amps, and if going by anything other than the cdr you'd need to know all the variables. How long is a pulse, how long of a rest time do you need after each pulse etc.

    you only need 60A to get to 200w

    Fasttech is wrong. While the VTC5 is a great battery, it is a 20A battery. Its temperature at 30A is over 100°C. This is way, way over any temperature that can be considered reasonable for a rated current level.

    Here are my test results...

    In a three batteries series setup (e.g. the Reuleaux) you need 23 amps per battery.

    220 (200w + 10% to account for device inefficiency) / 9.6v (the battery cutoff voltage, 3.2v per battery) = 23 amps

    That's still more than the cdr of three vtc5. You'll want vtc4s or LG hb2/4/6 for the full 200w.

    That is the typical efficiency. It will vary depending on the wattage output selected.
    Most regulated devices are most efficient at the higher wattage setting and less efficient at the lower wattage settings.

    DNA200 mods use a minimum 2x 18650s though, so in a shootout the 18650's will win.
