Hi, just reading your posts about batteries ...
"i thought the same, but both my batts are doing it. what are the odd..."
i've both the regular and the mini apollo ... and i can tell you: Some batteries are NOT DOING IT WELL!
Just look on this diagram with IMR 18350 and the discharge rate at 2 Ampere
Low performer are the Thrustfire protected 1200 (orange line)
Only the AW IMR 18350-700 (red line), the vmax IMR 750mAh (purple line) and NoName XBOMB ICR 18350 (olive line) are out performing.
So for an owner of the apollo mini it is recommended to take only IMR batteries with "safe chemistry". This would either be the AW IMR 18350-700 but he better choice is the vmax IMR 18350 750mAh. That's because it also has no "nipple" at the plus pole like these ones apollo delivered with and these batts were "especially constructed" for the Vmax batteries stacking.
I have now testeded 4 of these Vmax over the last 2 month and i only can tell they not even performing much better than the "original" (red / blue) ones from apollo and they last almost the double time bevor the are going down. Only negative thing is (here in germany) you pay almost the double price for the Vmax batts and they are only available as a pair. But for "heavy chain vapers" or people who are not willing to spend there time as a "battery changer" i would recommend them.
... hope i could help ...
vape on
p.s. If there is interest ... i also can post a diagram for 18650 batts
