Lets beat a dead horse and talk batteries

[Sivat Regrebieh]

Ive been searching this topic for awhile and find mixed answers. With today's ever increasing wattage on box mods, is there a safe alternative to the VTC batteries? I have 3 - VTC4's that have been in rotation (as well as 2 - vtc3's) on my mech mod for well over a year. And my normal vape is .3-.4. I have built down to .1 and .08 without these batteries breaking a sweat.
But now i'm looking at stepping up into to box mods. I ordered a sigelei 100w plus and i dont wanna use my ragged vtc4's in a pair in there. Granted this is only 100w mod. Some that are popping up are 150w or more, and some unregulated boxes are getting crazy with 3,4, sometimes 5 batteries stacked inside.

So i was offered some LG HE2's today for a decent price. Well under the $25 a battery i saw the last vtc4's go at. I've seen good reviews on these, but only in 30-40 watt mods? Has anyone tried these in larger mods? 100 watts or so? and pushed them the full 100 watts? Its apparent that they suggest ONLY 30A or better batteries in the 100w mods.

Anyone care to offer discussion or experience?

There are some legitimate vtc4's out there. http://www.xtardirect.com/collectio...c4-18650-2100mah-battery-unprotected-flat-top Other legitimate vendors as well if you prefer to buy from someone you trust more. Get 4 batts and swap out your married pairs. Or you could go with the lower continuous amp Samsung 25r's I have some of those as well and they work great.

The Samsung 25R cells will work fine in the Sig 100. At the minimum input voltage of 6.4V and set to 100W, current drain would only be 17A. It's about 13A on a full charge at 100W.

You can get the 25Rs for $6/ea with free shipping from Lighning Vapes by selecting the two pack and using code LV20. LV also had VTC4s in stock a few weeks ago (and may still have them) if you prefer those. The LG HE2s would also be fine if you are getting a good deal on them. Otherwise, $6/ea for the 25R is one of the best battery deals going right now.

The LG's are $9 each at the local store. Just wanted to have a good opinion base if they were safe or not.

How many watt can a mech mode crank up under the best conditions, build ect?
And how many watt do a Aspire CF VV 1600 mAp with an 1.8 ohm coil? How du I calculate such thing`s?

depending on the ohmload, it can get upwards of 70 watts on a mechmod. I run a single 18650 mechmod with coils at .35 so on a fresh charge at 4.2v I can draw about 55 watts.

Check out the Steam Engine battery drain calculator. Click on 'unregulated (mech)', set 'Atomizer resistance' to 0.14 ohms (a little low for safety, but we're talking about most watts and a hypothetical setup) and 'Battery voltage' to 4.2 volts. You get 30 amps battery draw and 126 watts. You've maxed out a 30 amp battery, but you're not actually vaping at 126 watts. Your battery and mod will rob you of some of that 4.2V so the voltage across the coil will be closer to 3.5 volts which gives you 87.5 watts of vaping pleasure . Of course that goes down as the battery drains and the voltage drops.

That battery is adjustable between 3.3V-4.8V. Go back to Steam Engine, click on 'regulated (APV)', put in the resistance, click on 'voltage regulation (VV)', 3.3 volts, 85% 'APV efficiency' and you get 6 watts of power. Change the volts to 4.8V and you get 12.8 watts. This is the power range you have to work with. If you change the resistance the watts will also change.
