I bought this set of Li-Ion battery and charger, (FNB-V67Li 2200mAh Li-ion Battery with CD-47 Charger ?from Aimtobest). Guess what? its fit is not right."
I am really surprised at the aftermarket batts not fitting. They fit fine in both of mine and a friend's ft60. They are a tight fit, but not much different than the OEM ones. I squeeze them down (without much pressure) and snap the latch on it with my thumb. Can you post a pic of it or you can send them to my email?
