Hi, my name is Vince. My yuneec Breeze 4k landed in a lake a few weeks ago so Instead of buying another one, I purchased a Spark controller combo from SAMS CLUB. I got the last one in the store and it came with an extra battery for $229.00. I then went to best buy and got another battery for $50. My concern is that all 3 batteries were manufactured in June of 2017. They were all completely discharged but I was able to charge and update the software. Does anyone know if the age of these batteries will affect their life span? I was considering returning the best buy battery because it was only purchased a couple days ago.
