Battery life? 1-day?

You are misunderstanding me, entirely. What you are saying is outside of my own experience, the documentation I have seen, the tests I have either performed or taken part in and about fifty years of experience with various forms of rechargeable batteries. I am trying to understand how you came to these conclusions is all, not be argumentative.

The thing about a Vamo, or other VV/VW device, is that it uses pulsed power to achieve the desired wattage or voltage (effective) output. I have measured current consumption on a Vamo in VW mode and it is higher than the power level it is set for because of that pules, buck/boost, circuit.

What are you using now? Just curious.

I use an 18 dollar mech from ft with an Igo l on it.

RC Groups - View Single Post - Battery graph vault.

Equipment: most every Thunder Power,iCharger,Hyperion ,iCharger and FMA charger made in the past 8 years as I beta tested all of them. Two CBA discharge units with Pro Version software , two Cam Light Systems CC-400 discharge units and numerious misc. one of a kind beta units which never made it to market.

I did not come here to argue battery care just trying to be helpful but I see that was a mistake.

FYI Volts X Amps. = watts thus 5A at a nomimal 4V is 20 watts. I vape my Vamos at 5.5 to 6.5 watts which is closer to 1.5 amps..thus why I used that as a discharge rate.

OMG!

Dude i know you don't want to argue but, if you don't have a pro analyzer like cadex or vencon etc we can't talk about batteries.
The chargers you mention are chinese TOY chargers and are not certified or calirbrated for precicion.
The graphs you show us (basically not graphs but posts of some things which you can't figure out because of the lack of data) don't show anything really.
You should know that the recommended charging rate for a li-ion is around 0.7C but it's always manufacturer specific and you also should follow the charging current cut off.
Basically you are right V*a=W but you forgot the power supply of the device. It contains a switched mode power supply probably in buck-boost mode, what this means is what you take from the battery ISN'T what you consume on an atomizer depending on the efficiency of the power supply.

You are right, missinformation is a mistake.

I just figured out the more I learn, the more I realize I don't have a freaking clue. This also happens when I watch jeopardy on a bad day lol.

When I was studying for my stock brokers license years ago I had the same epiphany. You can never know too much.

Chas_L, looking at the links you posted seems to show that you have worked, primarily, with lithium polymer batteries. I wonder if they have different overall discharge characteristics from LiMn or LiCo due the electrolyte required for them to operate? Heck, each differenct chemistry of lithium ion battery has it's own discharge, and charge, characteristic. Again, reading various reference sites for lithium batteries all reference the 80% discharge level as being the desirable level to discharge to before recharging but, again, that is pointed toward the cylindrical style lithium batteries without a polymer insulator between the anode and cathode.

My experience with rechangeables stared with Nicads some 55 years ago then NiMH of the SubC size before they were every available to the general public then Liion around 20 years ago mostly 18650s as used in Laptops. Mostly LiPoly data on RCG as that is what is mostly used however there is a great deal of Nicad ,NiMh and LiFePo4 data there also.

True all recharagbles are different however if one compares the very old Pb with the more modern types there is a basic simularity that being the deeper the discharge the fewer the cycles and the total mAh life from more shallow cycles is always greater than the deep cycles life.

As stated I did not responed in this thread to argue batteries. If one wants to read real data as in houndreds of doallars were spent collecting it do a search .

Here is one such study

Had to do the double take because, on the first pass, my eyes saw, or my brain translated, not sure which, the link into B&^!@$ Cheese which sounds like an 80s hair metal song title.
