Remarry battery set possible? Regulated mod

[The60WattGUY]

Guys i have a quick question kinda curious what your opinions are..

Anyway i have 2 30T 21700s samsungs that are pretty new still (2months or so) they were bought the same day the only thing is,
They were never married, but they do have the same amount of discharges i think because what i would do is use my thelema solo 21700 100w mod then when that battery is empty i swap/rotate it for the other one and vice versa and always charge them together same amount too..
Now here comes my question..
I really dont wanna spend another 20bucks just to get another pair these are only like 2 months old..
Can i use them together as a married set from now safely without hurting my device or me?
The batteries do have around the same discharges and charges tho since i swap and charge and rotated like that to give them equal use, but yea hopefully i can match them together dont wanna have to go out and buy another set, i mean i will if i have too id rather not..

Thx guys

That's exactly what I do and I consider the set married. Same number of uses and always charged together so yeah, I'd say yours at only two months old are already married.

Sweet yea i though id ask to make sure i believe if its around same age and cycles its fine but if you use 1 old and 1 new then thats bad ofcourse thats why people are so strict about it but this should be fine right thx bro @DallasLiza
