I am using a Finder 133 with DNA200 chip. I have set the correct watt hours and everything but for some reason the battery meter is wrong.

As you can see from the screenshots below, both batteries (LGH2) are fully charged but the mod still reads them as 85%.

That is probably the first time I've seen this and I have been using this mod for about two weeks now.

I charge my batteries using a Nitecore i2 charger (the old 500mAh) one but I sometimes use a Xiaomi Power Bank with an output of 1A when I am on-the-go and my batteries are low.

On a side note, I never fire while it is charging because I feel like it is unsafe, so I let it go up to 50 - 60%, for instance, then take the charging cable off and start vaping.

Please help because this is truly annoying. Thanks!

If it were mine I'd lower the watt hours by 15 - 20% and see how that goes,  battery performance won't be affected.

I used the calculator and it set it to 22.2 watt hours. What should I set it to then?

EDIT: You're right. I lowered it by 10% at first but it read the batteries at 90%, then I lowered by 20% (18watt hours) and now it reads 99% so I am guessing that's the most accurate number, correct?

Agree.
As cells age capacity drops, abused drops even more.

Thank you so much man. Does that mean my batteries are going bad? I feel like it may be the power bank on-the-go.

It depends on the speed that they are going South, a little is normal.

I'm expecting a pair of Sony VTC6 batteries in about a week. Would you happen to know if I need to find a discharge curve profile for it and use the calculator for watt hours?

The curve can probably be found on this forum.
I calculate 12.5% less than stated mah for 18650's ( on a 200 board)
Keep in mind that only the "fuel gauge" is effected not battery performance with the csv

So basically if they are two 3000mAh batteries, you deduct 12.5% from the total which results in a deduction of 570 from 6000, correct? Or do you just deduct 12.5% from the total watt hours?

600? AFAIK battery installed as series config. so it means either 3x18650 like triade250 or 2x18650 like finder 133. it still read 3000mah but double the amps and voltage. CMIIW
