[Elecraft] [OT] Note from a skeptic

[Al Lorona]

Late last week, I pulled my two-year-old LiFePO4 battery out for Field Day prep and found that it had failed. Efforts to reset the battery management system didn't succeed. I got to use this battery on exactly two Field Days, which means it cost me almost $200 per Field Day! Sad, very, very sad.

The dealer is honoring the warranty and a new battery is on the way, but I've become a LiFePO4 skeptic. I don't care for battery management system electronics that can fail where I can't get to them: sealed up inside the battery case. 

If stuff like this starts happening to everybody's electric car... oh boy, look out!
