    It's about a month old but this YT vid is about Iron air batteries....

    Agreed in all aspects. and even if it just were any tech that cold be used by big energy it cold relieve the demand for lithium cell materials. That could result in a price drop given how production is a a decent level right now.

    .... they sound too heavy for portable use in vehicles or mobil applications but holy cow chack out the energy density potential!

    Will this device allow me to charge a 12 FLA from my 12V LFPO? (Time sensitive if anyone has a min. it would help tons)

    Thx. 3A could be a last ditch option. that other one was 15... that's closer to where I'd chose to be. Good to know that things like it will do the job.

    Thanks for your opinion. I guess it's a question of if I'll get 40hr run time b4 it would croak. But as long as it will do what I need for that I guess I can look at reviews with that in mind...

    The link to the v1deo showing it is below. If there is a recommendation that could be a substitute of better quality at maybe 60 buck I'd probably go that route Just for the sake of a protective cased unit for travel. The purpose is to use a solar generators 280AH batteries to top off a...

    I am in the same boat. Am am not certain if it is even a concern for you, but I need to make sure when I get around to installing the batteries and new converter that the wiring from the converter to the battery is of adequate sizing to run from the converter positioned above the trailer's...

    A MUST SEE YouTube: "Off The Grid: Installing the Best New Lithium Batteries!"

    One of Wills (prob more than one) videos mentions pre=cherging the caps in inverters as small as 1500w with a ceramic resistor before attaching a LiFePO4 battery directly. I picked up a few small ceramic resistors for just that. They cost about 8 bucks, well worth the cost to just have one...
