I was given a Topas A4 pack by a friend. It has not been used for a while. However, I notice it takes quite long time to discharge (around 20-30s for 1 stop down discharge), however charging is very fast, and everything else seems to be working well. I have not had experience with Topas pack before (only a few Opus and Grafit).
Is it the way Topis is, is there some setting that I'm not aware of, or this one is due a service? Just want to check before sending it away. Appreciate your advice.
