Ace ChargeMaster
Well that's good to know, I've had an Ace charge master since about 1992 and never realized this. I always leave my planes on trickle when not in use, can't recall to many power outages. I almost always check my batteries before that first flight with my old Ace Voltmaster ll. Perhaps I've been lucky but I will be aware of it now, especially that I have recently acquired a second charge master by someone who left the hobby. They are a great reliable charger, just don't have auto trickle. I find all the older Ace equipment to quite reliable. Thanks for the info!
