Hi guys. Quick question. I’ve had my AWT Red 3000mAh batteries (2 of them) on charge in my Voopoo Too for about 40 minutes now and they’re almost fully charged. I feel like this isn’t normal and I’m wondering if I need to pick up some new ones? PS I know that using an external charger is better but I popped these in my Voopoo Too to charge them via usb deliberately to monitor the time difference. Was expecting the external to be faster but that doesn’t seem like the case.
