question about DIY Solar Garden Light Battery Charge 4 Solar Cell

[SunEagle]

I haven't seen one of those yet; maybe they're out there somewhere. I don't think I'd use one - swap the most expensive part of the car for another one that might be damaged? Seems like a bad gamble. But maybe with enough pack performance monitoring it could work.

From what I have heard you wouldn't be swapping your battery for another. You would be "renting" the stations battery while yours was fully charged. When you got back you would swap out the "rental" for yours. Of course there would be a rental fee but the premise would be time was more important then money so instead of waiting for your battery to get charged you would pay for the use of another battery and be able to get back to your trip quickly.
