Watt-Hour Shootout -- FullyMax 10Wh 900mAh 3S LiPo (for DNA200) vs 25R vs HG2

[Mooch]

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.

ft rates them at 30/60A

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.

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!

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.

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.

 

[Mooch]

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.

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

 

[KenD]

you only need 60A to get to 200w

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.

Yes but Evolv claims the typical efficiency is 97%.

Might be at a certain wattage, but not over the entire watt range. At least I have never seen a converter circuit that is.

Biggest killer is the screen. You're lighting up the screen 10x as much as a high power vapor. Try lowering your brightness and idle time.

Also I wouldn't count Escribe to be 100% accurate with the calculated mWH per puff.

I don't think the screen kills the battery as much as you think. I have left my display set too 100% for a month and then switched it to 50% for a month and no noticable difference.

You could put your mod in stealth mode and I don't think you will notice any extra vaping time. My Sigelei Mini has a bug in the firmware if you vape up to the 10 second cutoff, the display will never turn off. And it will sit for days with the display lit.

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.

Ohhhh you tease... Grrrr... Well I suppose I have no choice but to bookmark your blog to keep updated. ;-)

Programming my lg hg2 into evolv, how many Wh do I put??

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.

 

[KenD]

use VTC5, has cdc of 30A and max of 60A

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.

Would you think it could be as bad as 56%? That is what Steam-engine is trying to tell me. Maybe I didn't reset the puff counter when the batteries were full, but afterwards. As EScribe tells me I am getting 700 puffs, 10 second puffs, at 10 watts on average with three Samsung 25R.

Figuring it another way from EScribe, 25.25mWh per puff at 700 puffs = 17.675Wh. I drained the batteries down to 3.10v each (the recharge capacity said 2400mah from 3.10v). So I used 26.64Wh of battery power. So 17.675 / 26.64 = 66%.

I guess I'll run the numbers again in three days (that is when I predict my batteries will be at 3.10v). And maybe I am remembering wrong. But I thought I got 600 puffs, 10 second puffs, at 10 watts off of one Samsung 25R on my KSD Vamo 40W. I just checked Steam-engine and it says no I should be getting just 300 puffs at 10 second per puff at 90% efficiency. I just might have to fire up the Vamo again.

Yes it is quite possible to be that low at 10 watts.
It specifies 97% typical. I don't think they would consider running a 120-200 watt mod at 10 watts to be typical.

 

[BillW50]

Ok I figured it out where the extra power is going. The DNA200 uses a CPU, RAM, and ROM, right? And it won't be unrealistic that it could be drawing up to 4 watts of power. If it was drawing 4 watts of power, that boosts efficiency right to 100%.

 

[edyle]

Here is one way I can do it now. EScribe says I have 24.034Wh left of 27.75Wh. That means the battery had used 3.716Wh so far. But the DNA200 output only put out 2.263Wh. That is only a 60% efficiency. This is starting to get depressing. All of this is under TC. Maybe it gets better using just wattage mode.

Well if you are using TC mode, you don't really know what the wattage is.

 

[edyle]

EScribe tells you what it is. Plus you can change the display on the DNA200 to always display the wattage.

Do you realise the wattage is not constant when you are in TC mode?

I think your 57% and 60% efficiency values are probably because your numbers are just wrong as a result of using TC mode.

No circuit is 100% efficient. Heat is generated and efficiency is lost.
