Hi. Not sure if this has been answered before, but I looked all over and can't find an answer. I have a wismec tinker2 which I have owed for a few months. Now all of a sudden its not discharging the battery properly. One goes completely flat while the other shows full. Which this happens even when not in use. I have updated it and got some brand new 25r but still the same. I charge them in 4 bay charger and the batterys work in other mods. Thanks for your time.
