Charging two of 12 for test flights. I need to trust these batteries. #5, purchased 8/21 and #9 purchased 9/21. Evo 1. Maintained at 2-3 lights over the winter. No known issues with drone as of last flight and only one firmware update since new, and have found that is best at least in my case. Seems like the last of the cheap batteries have dried up so I hope these remain reliable or Evo 1 may be nearing its real life span. Purchased this back in late 15 early 16, original props but have many new sets. I'm a little rusty wish me luck.
