My SnowWolf Mini

[lizzylinkdemonwolf2123]

Yeah, my mini has the inner sleeve to be able to use both sizes. I buy my 21700s from a good reputable vape shop in my town. I'm just not sure why a full charge battery goes down to a dying battery view on my mod screen when I hit the fire button even for a few seconds

My batteries also have 4007mAh power

My batteries also have 4007mAh power

What make is the battery, and what is the amp rating?

 

[MrDJ]

think you still need a dual 21700 mod as your using 90w which is a strong drain on a single.
i use single 21700 molicel P42A 4200mah and that still can drain quite quick at 50watts.
fully charged for 8 mile journey and was on 1/4 by the time i got there. you are using almost double the wattage i am.

The strangest thing is though I've used the same batteries on The Mod before and never had an issue with it the highest that my 21700 batteries can go is 111 w and it's one of those hohm type batteries 3.6 volts but I'm very confused even though I use a tfv18 on it because I've used my tfv18 on it before and it never had an issue until last fall I'm so lost the mod only goes to 100 Watts but I've never used wattage on my Wolf mod that's higher than 90 Watts so it still doesn't make any sense if I'm using a powerful battery but the second I go to hit the fire button the power and the battery charge goes to almost nothing at all it doesn't make any sense it does the same thing if I go down to 80 Watts whether I'm using one of my large batteries or one of my smaller batteries

What is the amp rating of the batteries you are using? If it is borderline, then after time they may have degraded. As you are using a regulated device, it probably won't let the device fire if it is unsafe.

This is what mooch says about your battery.

These tests below only note the ESTIMATED ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, Murata, LG, Panasonic, Molicel, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.

Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a physically and electrically protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition. Use of any of these batteries is AT YOUR OWN RISK.

Testing batteries at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.

If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.




Bottom Line
This is a good performing 21700 cell that has a slightly exaggerated capacity rating. It performs about the same as the Samsung 40T but not as good as the Molicel P42A.

The capacities for the three Hohm Run XL (not Hohm Run) cells I tested ranged from 3984mAh to 4035mAh at 800mA (0.2C) down to 2.5V. This is pretty good consistency but one cell failed to meet its 4007mAh rating and the others were very close to the rating. I like to see cells test out at least 100mAh above their rating to ensure no cell, due to normal cell-to-cell inconsistencies, can be below the rating. I am rating this cell at 3900mAh.

The three cells reached 79°C-81°C at 30A. In my opinion this is close enough to Hohm Tech’s 80°C max rating to give these cells a 30A rating. I prefer a cell to run at a few degrees below the max rated temperature at their rated current level though, to ensure that normal cell-to-cell differences never cause a cell to go over the rated temperature.

Hohm Tech gives these cells a “temperature limited” rating of 38.6A. This means you could run this cell at 38.6A as long as you do not let it get hotter than 80°C. But I recommend not going that high as it increases your risks, reduces performance, and speeds up the aging of the cell.

This cell has Hohm Tech’s new wattage-based ratings. It is rated at 87W continuous and has a 111W temperature-limited “max” rating. As long as you don’t let the cell reach 80°C Hohm Tech says you can run it at 111W. They do say this reduces the life of the cell though and I agree. To reduce risk, extend overall cell life, and increase performance I recommend not going over about 25A or 75W. All cells are stressed when you run them near or above their ratings so this is not a recommendation just for the Hohm Run XL cell.

The new wattage-based ratings system, when fully implemented, could make things easier for new vapers to choose the Hohm Tech cell that best fits the way they vape. But it means they might not learn about current ratings and other things they will need to know if they use any other company’s batteries. I’m torn as to whether it is a good idea or not. I look forward to seeing how the community reacts to it.

Some of the ratings on the wrap are still printed quite small over a patterned background. This makes them hard to read, reducing their usefulness to vapers.

Performance Specs

• DC Internal Resistance = 12.9mOhms*** (milliohms) average for the three cells.
• Watt-hours (energy) delivered at 10A down to 3.2V = 10.7Wh
• Watt-hours (energy) delivered at 20A down to 3.2V = 9.7Wh
• Watt-hours (energy) delivered at 30A down to 3.2V = 7.6Wh

Is this to say I'm using the wrong batteries? Because no matter what batteries I use, large or small, I get the same outcome. My batteries still have the original wrapping too. My 18650s, are made by Imren with 3500mAh power and they don't work with it either. I think I need a serious repair person to help me face to face to get to the bottom of it. I'm just so lost with it

Nah what I'm saying is you are expecting too much by vaping a single cell mod at 90w

 

[MrDJ]

Question. why are you vaping at 90watts?
is it because your coil states eg 50-90w
im using 50-85w coils but am vaping at 35watts max. used to be 50w but for the difference in flavour and cloud im happy at 35w as coils last longer and i still get my 3mg fix.
