In light of a couple of recent news stories about Li battery fires while charging this is cheap protection for Pedego. Much better than waiting for CPSC to do the recall. I noticed that one reader commented that he thought 5K batteries over 3 years didn't sound like a lot of bikes, but Pedego really emphasizes rentals in their business plan with dealers which may be reflected in those numbers. Also, the total annual sales of ebikes in the US is still small compared to regular bikes, just barely 120K.
