"It lists a charge voltage of 14.6 volts. It seems to be made as a direct drop in for an automative battery. I believe you should be good with a charger that you can adjust to 14.6 volts" David, thanks for the opinions.
Ok, I thought auto batteries are high on cranking amps, never thought of 100A as ideal for starting a car. Not to worry though, this is my GA dry run, I will buy equivalent battery new near the project, it is over 2000 miles away, that is what I am trying to reiterate, really remote.
From my post yesterday:
"Since the LFP battery is small, only 245wH , i desire keeping another battery set to charge during daylight hours"
That is my 12v external LFP, with quadruple the power in storage. I can charge it during peak daylight hours. (From the Ecoflow&&&&&)
The house gets 300 sunny days per year and rarely drops below 2 C in winter. When I am using tools and lights at 3 am, for example, I would potentially need to use this BACKUP battery feeding juice to my ecoflow unit via DC charge port. I have the approved cables. No, I never envisioned any other way to use the external LFP"
I am glad you agree that I only feed the external battery from an AC source. And like i pointed out, i will feed DC power back to the Ecoflow when needed its 1024Wh feeding the internal battery which is 245Wh. But I won't be working down the lane from my house. This is why I am testing everything at home, in advance of my journey. Today external fed the internal battery smoothly and efficiently
