I heard a strange charging theory yesterday and I wanted to propose it here and see what others thought.
Someone recently commented that since lifepo4's will take as much amperage as you can give them very quickly, you can feed them power directly from a high amperage 12v alternator (in this case a homemade 12v gas generator with a high-end vehicle alternator producing the power) to the battery. Literally just run your wire from the alternator to the battery posts and zap that battery to full charge in just a few hours (we're talking parameters around 12v 50amps going into a 12v 200ah battery, for instance). This person's theory was that 1. you're not going to overwhelm the thirsty lithium battery since they like getting charged quickly, and 2. the alternator tops out at 14.5v, so it 'can't overcharge' the voltage of the battery, therefore running it through a charge controller of some sort wouldn't be needed.
I'm hesitant on this. Thoughts?
