I just got my XR1, done two dives, then as explained by others ... displayed FLY for the reset of the day, next day, i checked: the battery is damn low, and by end of day 2 -> died

I went to the local store and got 2 replacement batteries (cost here is Duabi around 5 Euros each) ...

Is that normal? i don't think so? might the original battery been half drained or something?

I will try to put one of the new batteries and keep you posted
