Yeah, I have the trinity real time 2 tray. Right now I am using an old Tekin BC100L charger but it gets the job done. I could just leave them on the tray, but of course I only have one. Should I just bring them down to 0.0v and then take them off and store them for the week? I just heard that storing them dead shorted was a way to get more voltage and run-time. Anyone else have an opinion on this?
