Did the test include thermal readings from the batteries as the test was being done? The batteries may have "performed better" as far as electrical drain during the test goes, but they may have also run much hotter which would shorten their lifespan as well.

And a 20A test doesn't mean either battery is safe at nearly 25A.
Yeah, it factored in battery temp too.

Yeah, battery life might be affected, but considering the only batteries rated for above 20A continuous are VTC4/5, their life spans aren't going to be much different than running all the other 20A batteries people run in these mods.

but it wouldnt make any difference anyway right? The Joules is how much the batt has given out, ore or less regardless of how you do it. If you vape at lower joules, it will take longer in time to get to say 20KJ but it will stillget there...A pint of beer is still a pint whether you sip it or chug it in one...or am I wrong??

I am in agreement. However, higher wattages / joules will get to that total joules faster (hence shorter overall run time before charges) and also... at lower joules you will obviously have more screen on time -- not sure how much battery that eats up, but will be some., and decrease the total joules count as well as total run time.

Nope. Battery capacity decreases as current draw increases. Most batteries provide their advertised capacities at a low C-rate. For example, the HE4 is given at 0.2 C, which means (2500 mAh)*0.2C = 500 mA. At it's max continuous discharge rating, on the LG HE4 you'll see around a 10~15% reduction in capacity versus the advertised capacity. Some batteries are worse than the LG HE4 in terms of reduced capacity at max discharge, some might be better.

of course I agree! However, we are talking about a difference here of say 24kJ versus 35 or somnething nuts!!

ok but a 30% difference?? An extra 12-15kJ??

Actually I'm thinking it may be the way v1.4 is reporting total joules vs. the way v2.2 does it. I'm downgrading mine to 1.4 tonight to test this. My calibrated (;)) 5 sec drag results in 70-75j right now in v2.2. I suspect on v1.4 it will be as high as 100.

Well looks like the v1.4 file on the yihi site might be corrupted. Upgrade looks like it works and verified that v1.4 loaded on the device but screen is scrambled on the first digit on the temperature and it can't be adjusted. Anyone know if the file may exist somewhere else on the web?

The file you downloaded could be corrupt. Try downloading it again.

Yep. Did that twice and have tried upgrade with battery in and out. Same result. I've got an email in to Yihi…
What is the file extension of your file? If it's *.man you have to rename it to *.rar

It may say rar at the end but that could be just the end of the file name and not the extension

Ok go to the "folder options" under tools or help in the window..

Go to advanced tab and deselect " hide file extensions" or something to that effect... Then you'll see *.man at the end of the file name... Right click and rename that .man to *.rar then unzip then use that ski file

When updating take out the battery and update without the battery in..and use a nice thick mini usb cable... Those ribbon cables aren't stable enough


I dunno if this applies to the 1.4 file but worked on the 2.2 file

Steve,

I am not sure your analogy is correct. After all the battery efficiency is higher at lower current draw and therefor should provide more power to the load. I think you could get into I^2 * R losses when running at higher current draws. Poor analogy driving your car at 100 mph vs 55 mph.
Hi George. Mine is a poor analogy really. I guess I am just surprised that getting an extra 10+ kJ can really be attributed to battery efficiency/losses under loads that are pretty similar really...Your point is well taken!!
