Hello, I've just got my Inspire X5, and bought two new TB48s too. Charged them fully for the first time, and updated the firmware on both. Do I need to discharge them and recharge them fully for good measure? I've read a lot of horror stories about uncalibrated batteries causing Inspires to drop from the sky, and obviously this is something I want to avoid on a £3800 kit! Just wondering if others would recommend this, and if it is necessary for safe flight, as I am yet to try the new batteries out. Thanks for your advice, loving the Inspire X5 so far!
