I have a Finder DNA75c from Think Vape. I have 6 Sony VTC6 batteries, charged by a Nitecore D4 charger. It's my first box mod, and all the above were purchased in March.
Monitoring the battery charge levels in the mod, I thought that I was getting poorer use time than I anticipated, particularly as I typically am using 9-17 watts depending on the tank build and juice. I noticed when taking the "depleted" batteries out and placing them in the charger that one battery would indicate a nearly full charge, while the second would indicate a partially discharged state as expected. At first I thought I simply had a "bad battery". I tested with other battery pairs, however, and the same thing happened.
Then when the mod showed it was time to change batteries, I experimented. I put only one battery in the mod (using the first bay position, i.e. furthest inside the mod). Trying both batteries in this manner, it showed one battery was indeed nearly fully charged and the other was partially discharged.
I then put both batteries in the mod, alternating the position in the bay. If the battery with a lower charge is inserted first, the mod reads total charge as that same as if only that single battery was being used. The reverse is also true, put a fully charged battery in first, and partially charged in second, and the mod reads out as batteries fully charged.
If I insert just one battery in the "2nd Bay", the mod does not function. I don't know if that is "normal" behavior.
As far as I can determine the DNA75c appears not to be capable of measuring each battery separately, which might be helpful in diagnosing the issue. Any ideas what is going on?
