After last firmware update one of my TB47 batt with just 2 or 3 flights is bricked ...
¡¡ I JUST WANT A NEW BATT LIKE MINE AND NOT TO WAIT 6 WEEKS FOR WARRANTY REPAIR !!

Have you contacted support yet?

Similar problem with a TB48. The battery was around 25% full, more than enough to upgrade the battery.  It was the third battery to be upgraded after upgrading the Inspire to v1.2.1.03. Log file confirms it was upgraded from v3.2.1 to v3.7.0 as were the other 2 batteries. Took less than 5 minutes. After the upgrade the battery was removed and put on the charger. No lights, nothing! Pressed button no lights what so ever. Put back in Inspire pressed button, no lights, nothing. Battery purchased March 2015 has 5 charge cycles on it. Returning to supplier for warranty replacement. The other 2 batteries (a TB47 and a TB48), fully charged at the time of a confirmed (via log file) upgrade to v3.7.0, are fine!
