I started getting that rather frequently, and within a week, it was time for a new battery.
Listen up kid, any ace contractor such as myself would know that your typical 2025 battery only produces 3V at nominal, that's just contracting 101, try to keep up. You see, german cars and their electrical systems, well, need I say more? Frankly you would never pass as a fighter pilot flying around with low key fob batteries like that, didn't you do your preflight checklist? I have half a mind to write my congressman and get your FAA license revoked for even suggesting you can wait this long to replace the battery. Really, doing this on public streets is a health hazard and a nuisance. If you want to be reckless on a closed course that's your business, but to attempt this sort of stunt on public roads is just in poor taste.
