DNA133 watt imbalanced batteries

[kingdal]

Hi ECF, got a question about dual battery DNA200s. I recently bought a Lost Vapes efusion Duo. The problem is after using it a while, the batteries come out imbalanced, like one is at 3.6v and the other at 4v. Then I tried a friend's Boxer dual 18650 DNA200. Same result, one battery came out at 3.7v and the other at 4v.

The batteries are a couple of months old and part of 3 married ones I used to use on a Reuleax RX200. I've tried mixing it up among the 3 with same results.

Anyone have an idea what's going on here? Thanks in advance!

It would appear that one battery is 'weaker' than the other for one reason or another. I would stop using them in a dual configuration and get a new set of batteries to marry.

If you've verified that just one of the three is weak, pair the other two and check the third for use as a single. But keep a closer than usual eye on all of them for a bit.

Its funny because i number my batteries and rotate all 3 through the mod's battery slots. So I've gone through all 3 in different combinations and in different battery slots.

But its simple enough to try out new batts. Thanks for the suggestions!
