Battery Tear Down: Renogy White Label 100Ah LiFePO4...

Thank you Gnubie :D Saved a lot of people from spending their money! Which is great.

I cant believe what was inside! Its always a surprise. I love it.

I really wonder what is inside the renogy...
 
WOW I got a buzz just looking at the globules of glue you pulled out of that blue box O goo. LOL.
Now a look see at the Renogy is certainly looming on the horizon.

Hi Will,

Thanks for all of the great reviews. I’m curious if you’ve ever done one on the AIMS 100 @12v LIFEPO4?

Don.
 
Any plans to tear down one with a Renogy label? I'd be intersted to see the difference, if any.
 
I have to wonder if the person doing the gluing was wasted on the fumes or not...
I just don't get why they use 4 good cells, a reasonable BMS (compared to many others) and go stupid with the wire & packing, plus the glue of course.. For the little extra effort & patience and a few pennies that could have been a winner...

Now the photo's are misrepresentative and there is no disclaimer that the actual product may vary or anything like that.. that shouldn't be a surprise to anyone buying anything off the internet these day's, should it. Sometimes it's a good surprise and other times not so much.
 
If it handled the heat gun for that long its fine for most RV/camper applications IMO. a microwave or small toaster oven for 5-15 minutes. Those looked like 8awg and they're only a few inches. Id say its a winner for the price as long as you know what youre getting.

If I am not mistaken Will said it was 2x10awg so thats effectively 7awg instead of 2x8awg which is effectively 5awg.
I just double checked and he says 2x10awg @5:57
 
If the Renogy battery is significantly different inside I'm not sure you can call this one a "White Label Renogy". Seems to cast dispersion on the Renogy brand. If some cheapo manufacturer just decided to use the same case, one can hardly call this a Renogy. Guess we'll see when the real one gets cracked open.
 
I know but they look like 8awg to me. Either way at what 3-5" not more than .5% vd @ 100A.
 
The Renogy batteries spec sheet list using IFR26650 3.4AH cells. I believe these are cylindrical lithium cells and not prismatic packs as shown in this teardown. The spec sheet lists a 4S30P assembly method, which I believe is the same method as Battle Born.

I expect a Renogy battery will look different in the inside and this "white label" just used a case similar to Renogy. I am curious about a Renogy teardown as well, especially as Amazon shows the batteries at a discount as of 22 Dec 2019 ($599 for 100AH and $1099 for 170AH). That is a great deal if the Renogy build is better, you have a climate-controlled space, and do not need to stack the batteries in series.

I sure hope the Renogy are not built the same!!! I also took advantage of cyber Monday and bought 4 of them.
 
The battery isnt pretty. But there is good cell and a ok BMS. So what is the issue with this battery? it past the capacity test with flying color. I understand it s not build to the level of a battery born but letting emotion aside..... it seems like it would do the work in a 12v RV system and truck along just fine. What i would like to see is some kind of objective failure in a test. The battery tear down is great but...the battery did do what it was mean to do....
 
You've missed the point a bit here I think. Look at the quality of what the seller says they are providing, then look at the quality of what they actually provide. Tad different, isn't it? If you bought a luxury car and it turned out to be a mini moke with a fibreglass shell over it that looked like the luxury car, sure, you can drive around it in but I don't think you'd be all that impressed etc.

you are absolutely right...the picture (false advertisement) and what is in the battery are very different. Not a very professional way to conduct sells. But once again, my question is.... what will fail first in this battery? will it fail? or will it go on and on and do it s job? I m asking as i want to learn about all this. I m interested in where the failure point will happen?
 
For a start, note that while everything is glued down, it's all pretty wobbly. We've already seen several examples of BMS connectors coming off in another brand of battery where the manufacturer pulled a switcheroo. Pretty good chance the same would happen with this one. I'm sure a re-watch of the teardown would provide more examples of why the battery is crap.
 
youre paying $100 for a BMS and a case over the raw cells. If you buy it all in component form youre not ahead.
