In searching around the web, I came across a reference to a Moll Power Industries lifepo4 battery. After some searching I found the company website, and they are in Miami. They deal in large format printers and lithium batteries. There are other references to Moll Power in other industries but...

Thanks for posting, i've been off for awhile due to planning for two memorials this summer back east and had to put a loved family dog down this weekend so I have shelved this idea for awhile. Also since Arizona is on fire again camping has been postponed for the summer This looks super...

Yes, I have dug into this before, the last time I was trying to figure out if it was better to bay a unit or build one and with the help of those here I decided to try the build route. Now I am trying to find out the best components to use and what is needed to charge and best use the batteries...

In the next week or two I am going to start the process for building a battery backup for mine and my wife's Cpap systems. This is for off grid and when power goes out. They both draw about 150 watts a night and will run from 12v. That should go down once I move to 12v. In addition when I am...

I live in Southern AZ so yeah we have abundant sunlight. Once done, this system is for when we go camping, or power outages, and will run two cpaps, charge phones and maybe a light or two so probably a little overkill for now. When retirement gets here, hopefully soon, we are going to travel...

I haven't forgot about this and am still looking forward to getting it built. I think I am going to go with the batteries from the group buy page and build up the box. I should have funds next month or beginning of March to order the batteries. For a 12v 270 AH battery how much solar would be...

I like the looks of these, they seem better than the power meter that loses everything every 24 hours. Have ou used these at all? Bob

I am thinking of using lifepo4 batteries to build the battery bank for the cpap. It is more expensive but it saves a whole lot of weight I don't feel like lugging around. The AGM's I have seen weigh about 24lbs for 35AH battery. Plus its much easier to find an inexpensive case to build with...

I was finally able to test mine last night, it is a Phillips Respironics System One Series 60, pressure 10. peak 80w low 1.3w both with the heater on. This was over 13.5 hrs with a total of 285w. Unfortunately my power meter doesn't break it down by night

Cant wait to hear the results, I have a System One and the humidifier is a necessity in Az, when we traveled to Washington state not so much. I could actually go without it for a couple nights. I have a power meter on order and it should be in Monday so I can read my system then and figure out...

The goal is a working system, once I show the wife it works then I will buid a second for hers and redundancy so if one breaks we can use the other until I can fix it. Trying to find the best parts for the money with the best reliability thrown in. I'm not looking at cheaping it out but I also...

Is there a difference between the OEM cord and after market, except the $20-$40 price difference. Also a folding or portable solar panel is in the future, I need to get this and prove it out before SWMBO goes out to use it. Yes you are correct, right now is camping and in a few years at...

Agreed, everything I'v seen even from the mfg says dont use the humidifier on battery Bob

Nothing wrong with bigger, I had figured that the 18650's I was looking at should last almost 11 days, if I recharged every 5 days min I should be good. since the cost would be close is there a difference between using the Fortune cells and 18650's if the cost and AH is relatively the same? Bob

LOL, that sounds like a visit from Karma! I see I was misunderstanding AGM's, what are some of the better quality ones to look for? A quick search shows comparable Ah rating with prices widely fluctuating. A few brands to look for would be a big help Thanks
