I enjoyed your video and I like your style of presentation. I don't make YT content, but I do consume a lot of it and, for the last 2 1/2 - 3 years, much of it has revolved around LFP batteries, chargers, inverters, solar panels, etc. I've built a number of emergency backup power systems for my home here in tornado alley and have bought lots of testing gear to play with just because I'm retired and have always enjoyed lab type work. I say all that so I can say this and you won't think I'm just popping off. I think I know what I'm doing and I just want to help you if I can. I think the reason that you came up short on the capacity test is because these (and actually ALL batteries or rather the cells that make up the battery) get their capacities tested under a set of standard criteria. For LiFePO4 batteries they are only expected to deliver their rated capacity if they are discharged at no more that 20 % of their AH rating. A 100 AH battery has to be discharged at 20 amps or less and should be able to do that for 5 hours. The battery that you're testing must be discharged at no more than 40 amps and should last for 5 hours. It's referred to as the ".2 Rate" or the "5 HR Rate". Lead acid batteries, on the other hand can only deliver their rated capacity if they are discharged at the ".05 Rate", commonly referred to as the "20 HR Rate". For a 100 AH AGM battery that would be a mere 5 amps for 20 hours. If you exceed these discharge rates you get less capacity from the batteries in question and if you do it at a lower amperage you will usually get a little extra energy than the rated number. Now, having said that, let me say this, I've never ever seen anyone even TRY to discharge one of these batteries at their max discharge rate for the cells, even when the BMS is also rated for that current flow rate. All I've ever seen done was to make sure that the battery would deliver that current for 10 minutes at most, just to prove that the BMS really would support it. My hat is off to you, my friend because you just gave this baby one hell of an acid test!! I'm flabbergasted! Because of all the discharge specs and the scientific method that I pointed to earlier in this comment, I don't know how many times you could get away with this without doing damage, but by golly it worked once and that convinces me that this battery is absolutely legit. Please keep breakin' rules and makin' content!

Loving the videos, brother! I like your real-world testing of these batteries, very cool!

Much appreciated 🙏 Thanks for watching and commenting 👍🏻

The question becomes: How long will it last with daily off grid 24 hr use.... Is there a warranty?

@@JustinsProject You're welcome. I've been digging deep in to making my RV solar... However, I plan to live in it, so I will need not only enough power to run everything 24-7, but it needs to be reliable. The higher end batteries come with at least a 10 year warranty...

What's the point of sending out your product when the link to said product leads to a "currently unavailable"? What, did they have only four of these for sale?

I'm not sure I follow your comment. I checked the link I added in the description, which is an Amazon link, and I see that they are in stock and ready to ship.

@@Dirt-Diggler That's probably it. Amazon doesn't offer this in my region so I don't get to see any pricing either.

I guess it could short out on cardboard
