battery pairing

[joeyzx2]

hi, im looking for some info on batteries. ive been using devices that have built in rechargable
batteries for a while now. i recently won a sigelei 150 in a contest.. so i ordered 4 samsung 25r 18650s
havent charged them yet, so i was told i have to pair two of them together and them at the same time
and only use those two in that device, my question is can i pair all 4 together so i can just swap pairs when
the first two die? thanks

Yep, the way to do it is have two pairs. But the thing is, you don't want to mix and match these pairs.

So you have four batteries, I'd start off by labelling them (if you can), "1A, 2A, 1B, 2B". The A's always go together, and the B's always go together. The A's never go with the B's/vice versa. Not only that, it's a good idea to swap the positions of your 1A and 2A, so on day 1 you'd put 1A in the left battery slot, 2A in the right. The next day (or after charging) put 2A in the left, 1A in the right.

As long as you never mix set A with set B, you should be totally fine.

+1 on what @nyiddle said.

Also, if you are going to be vaping at 100+ watts you should be using two 30A batteries (like they Sony VTC4's). The Samsung 25R's are a 20A battery.

Exaclty what Nyiddle said. I have two pairs of Samsung 25r's. I am picky about WHERE I place them in the charger as well. I have a nitecore i4, and it has two "bays" so to speak. Slots 1&3 are on one bay, and slots 2&4 are another bay. As we speak, I just had one pair of samsungs on slots 1&3 finished charging.

I don't know what charger you have, but with the nitecore, it splits the charge between different batteries on the same bat. For example, it might have 1a charging capacity per bay. I slot a paired set in one bay so they will use the same electronics for that bay. At least, that is my understanding for it. They both charge at the same speed. The PROPER way to charge, is to alternate between which slot on the bay they get put on. Me, I don't go that far in depth, so it may reduce the lifetime of my batteries.

thanks for the replys guys, you guys answered my question perfectly.
i have a nitecore UM20 charger, it only has two bays. and also i dont plan on vaping
100 watts or over , honestly i probably wont even go to 70 or so anytime soon,
ive been happy with the 30 to 40 watt range.. if there any other useful tips id appreciate it.
thaks again

The Sig150's battery indicator is weird. Don't let your batteries get below 50% or so, as the Sig150 has no problem draining your batteries below 3.5V (which could, potentially, damage the batteries/decrease the lifespan).

From 100% to 50% is a full day's vaping for me, at about 60-70W.

thanks again, i will remember that

And now in all 50 states any battery can choose to marry the battery it wants. That was a nice prize you won. Congratulations on that
