Hey vape fam, I just ordered an istick 100 watt and 2 Samsung 25rs. I know your supposed to marry the batteries but I've also heard u should label them like 1 and 2 and switch them everytime u recharge. Is this really necessary or should I not worry about labeling them I had an unregulated parallel box before and I Swicthed them back and forth.No problems occurred. I know the reasoning is so one battery is under all the stress. Also were the samsungs a good choice? I ordered them because I heard that's what most people use in there regulated devices.

The Samsung 25R should be good up to 100watts occasionally in the iStick100w. Yes, rotating the position of a married pair in a mod is an extra safety measure, even rotating them each cycle on the charger of which bay helps as well. My Sigelei150w and IPV3, pull the batteries out to put them on my charger, the battery closest to the control chip generally has the most draw off it, most the power pulls and flows through it, though these are series config mods, example batt1 in bay 1, batt2 in bay 2, put them on the charger batt1 reads 3.5v, batt2 reads 3.6v, next time in the mod and go to recharge them, batt2 in bay 1, batt1 in bay2, batt2 reads 3.5v and batt2 reads 3.6v. So yes it is good practice to not over stress one particular battery in a married pair, balance their usage cycles as best you can extends their life cycle as well as increases safety. For say month down the road, not rotating the batteries, batt1 could be 3.9v compare to batt2 being 4.1v on a fresh charge, weak link where potential failure will be is at batt1.
I've go 6 sets of married batteries, and label all my batteries of date of first charge, then with married pairs, bottom cap I mark 1A/1B, 2A/2B, etc so I can keep track of oldest to newest, and how many charges each pair have had.

I number all my batteries too, it's very helpful. You want the batteries to have the same experience like stated above, so that they operate and age the same way.
Try labelling them 'A' & 'B' or 'A1' & 'A2' or whatever you fancy. Always charge them pairs at the same time. I try not to discharge down to 3.9V as this can deplete battery health & affect their performance, I read.

Samsung 25 rs are very good batteries.
As long as you charge and draib them together all will be fine. You don't want one that has a memory and will only charge to 90% with a brand new because you will quickly setup a memory in the new battery and never get the full potential.
No memory problems with Li-Ion chemistries. That's just with NiCd/NiMH batteries.
Samsung 25R is an excellent cell, yes marry them, yes label them. I date mine too.
I don't discharge down below 3.6 volts if I can avoid it, and I only charge them to 4.1 volts which extends their life apparently.

Mooch respectfully disagree.
li-0n batteries do not have a memory anywhere as bad as ni-cad or NIMH
But ALL all batteries will develop a memory given enough use. Basubg that on my iPod touch. In the beginning its li-,on battery would last almost two days using it as s computer. After two years I could not get through 1 day. Had to plug it in as soon as I got home.
In my opinion that was normal capacity fade. Over time, and additionally for each cycle you put the battery through, the capacity will go down. There's just no industry or academic suppprt (via research papers, manufacturer application notes, etc.) for the concept of Li-Ion battery memory.
I dont think what you describe is "memory". Your device's battery is just simply approaching the end of it service life. the number of discharge cycles, operating temp, and stress affects battery capacity over time. charging it about every other day for 2 years is 365 cycles
Yes I do [emoji1]you must swap out batteries alot ....

You can discharge your batteries down significantly below 3.9V without causing any damage whatsoever. The nominal operating voltage is 3.6V-3.7V, the voltage at which it's designed to run at for a long time. And you can drop below that without problems.
If you want max battery life, don't worry about bringing them down to 3.4V-3.5V. The difference between that and 3.0V is small, but it might be noticable. You will then be able to enjoy most of the capacity of the battery but still ensure long life.
And do not charge them above 4.1V (do we have chargers where we can set voltage limit?)You can discharge your batteries down significantly below 3.9V without causing any damage whatsoever.

They're out there (like the iChargers I have) but I haven't seen that available in the chargers normally recommended for vapers. I'm hoping someone proves me wrong though!
Until you are drained. Then you should switch places, and be right and left.
"In sickness and health" may be a problem
Having a two battery mod and a 2 bay charger makes life so easy for keeping married pairs in the proper side rotation. When I take them out of the mod, the one that is on the left side in my mod goes in the left slot on the case i keep them in. Then I flip the other over so the positives are at the same end of the case and put it in the right slot of the case. Charge them in the same slots as they are in the case. When I go to put them into the mod again, I grab the battery from the right side of the case and put it in the left side of the mod, and then put the other one in the right side of the mod. Lather, rinse, repeat.
