I was wondering if i could take my sony vtc4 from my mech mod to use in my new ipv3 150 watt? Anybody help would be greatly appreciated
Of course you can.
really? i heard about people suggesting that you have a pair of twin batteries that you charge together and use together? Idk i could be wrong but I'm just trying to make sure
Your original post didn't mention anything about 2 batteries, it only said "I was wondering if i could take my sony vtc4 from my mech mod to use in my new ipv3 150 watt?"
So I guess that would be a dual battery mod?
Stacked in series; so yes you should buy a pair of new batteries for it, mark them A and B and rotate them.
batteries in series should have the same life... if one has more charge cycles on it, or one has been drained to a lower level than the other it could force the 'stronger' battery to pick up the slack, putting more stress on it. If batteries from the same batch (from the manufacture) that are always charged and drained together both should should power the mod equally, instead of one having to pick up the slack. This is why it is reccomended that you "pair" your batteries with dual 18650 mods. Keep them together, use them together, charge them together, and never use one without using the other - never charge one without charging the other.
IMO, if you got both batts a week and a half ago, used them both about the same amount and have not abused them, they should still be matched almost as well as they could be and you're good to go with them. Battery abuse would be things like discharging at too high an amp rate, shorting a battery, discharging too low before recharging, etc. After this though, the best plan is to mark each pair and keep them together all the time which means not to use them separately in the mech mod.
The reason you want them matched as best as possible is that if one batt empties before the other in the IPV3, the lower charged batt can become stressed enough to vent. You should also check battery voltages when you take out the batts the first few times you use them and then once in a while after that to make sure they stay matched.

This may be a stupid question, but if I take three authentic, high quality batteries ( same brand, same everything) discharge them at different levels, and then recharge them all back up to full capacity, are they not all the same? I know conventional wisdom says always match and mark two batteries to use in a two battery regulated mod, but are there actually any facts to back this up or could it just be a vaping myth? I get the whole "better safe than sorry" story, and I agree we should all be safe, but it just doesn't make sense to me. Can someone explain so I could understand?
discharging and recharging degrades the battery. if they are discharged at different rates, then they have a different amount of degradation. the larger the difference in degradation, the worse off you are. as a battery degrades, its mah rating will decrease. that leads to the two batteries reaching low voltage at different rates. then the less degraded battery will pick up the slack there will be added strain to the battery
devils advocate - wont they reach equilibrium at some point?
lets say 100% is a brand new battery, and 0% is at which point you recycle the battery - talking about overall battery life here, not life on a single charge.
you start with one battery at 100 and another battery that you've put a few cycles through sitting at 98%.
Assuming you are pulling somewhere around 20amps, one battery can handle that.
The dominant battery will do more work causing it to degrade faster, lets say the stronger battery now at 98% and and the weaker is at 97%.
Run that scenario one more time and they are both at 96%, at which point they have the same "degradation."
Like I said, I'm playing devils advocate here, I personally would buy brand new batteries and run them as "Til Death Do Us Part," but still seems like a plausible scenario.
