After running some tests, it seems like whatever pack I charge only charges to roughly 80%. This really has me baffled. I have the i charger 206B that when new 8 years ago cost me $100.00. I’ve certainly got my use out of it. I am really glad it is presenting this problem now before I decide to fly one of my EDF’s or helicopter. Would everyone agree it’s possibly time to invest in a new charger?
