    Buck converter to run power tools off ebike "36v" LiFePO4 battery?

    One stop for solar charging ebike info?

    Here are some links & notes I pulled together during my last research dive into solar e-bikes. Between the youtube channel, the presentation from the GRIN / ebikes.ca folks, and the info on the GRIN & Sol Mobil websites you should be able to get a pretty good notion of how the Sun Trip bikes...
