wtf was that? It could have been good but they screwed up so many things it was basically a bad infomercial.
300 amp hour battery? The standard alternator burned up at low speed so they ran the "good" alternator at higher speed and said it was better? They couldn't run the alternators over 3600 rpm because that was their max motor speed? They had a belt drive and VFD, that is a at least two paths to higher rpm. When the cheap alternator burned up it was at 1500 rpm. Aren't most engines running the alternator at two to four times engine speed? The whole thing was just so flawed you can't draw any conclusions from it for a normal use case.
I think it was to push a product but it did point out that one has to think about the whole system and understand the dynamics.
That looked like a massive battery and the relevance would depend on a number of factors starting with bike, car or boat. The fan cooling factor caught me off guard.
I related this more to a boat conversion where someone just dropped a big L-ion battery into the bilge and expected the stock alternator to charge it up after a day of using the trolling motor.
I did regulator to alternator conversions on a motorcycle and an inboard boat motor and matching RPMs of motors and alternators can be a bit of a compromise.
Yes on both counts.Aren't most engines running the alternator at two to four times engine speed? The whole thing was just so flawed you can't draw any conclusions from it....
