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!
