Litime battery is better. Its been tested at nauseum and works everytime.
Nice. I used your link and it's still got that coupon so I ordered one.
Awesome! Thank you!
Thanks. I wonder what the longevity of a cheaper battery like this is compared to the more expensive ones.
I guess only time will tell, but I bought two DC HOUSE LiFePO4 batteries about 6 months ago and they are still holding capacity like when I first got them. They were the cheapest ones at the time and I just needed 200ah for my RV residential refrigerator at the time. I am sure the expensive ones are better, but by how much? 3x or 4x better? No. If I can get 10 years out of them I will be more than happy with it.
great video information. Don
Glad it was helpful. Thanks.
The manufacturer labels Amp Hours because that is what people know. The measurement for capacity is standardized for Watt Hours.
Right. Everything is labed 12.8v and amp hour. Some batteries though have the watt hour listed too.
Test could be skewed due to crazy inductive loads. Both inverter and AC unit will cause hi frequency spikes of current drawn from battery. Most meters don't see those. I believe using a pure resistive load is the best way. Use 12 volt DC water heater element(s) would be the best way. Must put elements in circulating water bath!
I see people use heaters. I should try that.
What amps was your first test that got 102kwh? Batteries are normally rated at a 0.2C discharge so for rating a 100kwh the rating is at a discharge amps of 20. Your test shown was almost 50a or 0.5C so would expect a small drop in delivered capacity.
As others have said would be good to see a tear down.
Thus is what I think LiFPo4 batteries should cost but still seems too good to be true.
This is a 100ah battery with a 12.8v nominal voltage. That means it should store 1,280 watt hours. That is 1.28kwh. You would needs 78 of these batteries to equal 100kwh. You're right about testing at .2C, if you want to see full capacity. At this price, I would be happy with anything better than 95% of the rated number, but most of the time really cheap batteries like this one are built with resleeved used cells.
Yeah, it might not have been the same kind of load test. I was testing different loads with it.
Really? I did not know that. I don't want USED cells in a NEW battery. How would I tell if they were used?
@@SeidelRanch - It can be really hard to tell, but ask yourself how they're getting the price down much lower than reputable brands?
@@jasonbroom7147 I think it's 2 part.
American companies need/want a much higher profit margin from a product. Think Apple that charges $40 for a wall charger they source from China for 18 cents. There is some/few good reasons for that, but most of it's just to raise stock prices.
Small chinese companies are now figuring out they can cut some of the middleman out and selling on Amazon. In this case think TEMU.
But those companies charging $800 for a 12.8v 100ah LiFePO4 battery are just looking for the most profit they can squeeze and passing some of that to the marketing department to sell those.
There has to be a middle ground there where you get a good product for a good price. That is probably about $250 I would say.
Would a battery like that put out enough CCA to be used in marine uses?
Yes, for deep cycle uses like a trolling motor and pumps. Not high amps for cranking though.
The internal BMS would shut down the battery, too much inrush current.
@@KA9DSL Right, for cranking I don't think it would peak that high. Usually you want 500 or more amps available to spin the starter. Maybe for a small motor, but it would have to be pretty small.
You can’t even buy good lead acid batteries for that price! Great review!
Thanks. Yeah, these batteries are getting cheaper by the day.
The $159.49 price didn't last very long. Now $217.49 12/15/23
You have to apply the coupon.
@@SeidelRanch That works if one is only buying one battery. If buying more than one, the coupon only applies to ONE battery in the whole order.
@@Tumbleweed5150 Ah, I did not know that. I guess that would be cheapest for 1 battery then. I think the prices are going to be dropping for a while on these types of batteries.
This one has cylindrical cells. Wonder how that compares to the prismatic cells?
That I don't know. Aren't most of the cheaper ones cylindrical cells? Somewhat new to these batteries.
pouch cells
@@MacMcCabe2456 Oh, that is good to know.
what does the insides look like!
I get asked that more than I thought I would. I think I might start cracking these open when testing. I did not want to ruin the batteries because I do use them, but maybe I can get them open without destroying the battery. Keep an eye on the channel for those type of videos. Maybe I can do another video on this one.
You did a test on this battery already correct ? Why two tests of the same battery on youtube ?
I usually don't, but I do have 2 channels I can put videos on, and I wanted to test this one again since I was very surprised with the first results. I wasn't expecting it to do as well as it did. The second test was closer to what I was expecting but still a little surprising. I think my first test had a lot more fan time on the ac than the second test. Since I had 2 videos, why not.
Think I'll pass. Their only presence seems to be on Amazon. No warranty implied and their website only advertises flashlights.
Might be worth the chance for just a one off but not for meaningful storage capacity.
I get it. It's hard to put a lot of trust in a cheaper battery with no real presence other than Amazon. It's all based on what you need and what it will be used for. We always have our generator with us so there is no real big issue if it fails.
There $299.00 now!
Where do you see that? I see $217.49 - $65 coupon = $152.49 right now which is cheaper than it was when I made the video.
Bad BMS, LiFePO4 battery it should shut down at cell voltage of 2.7V, if you want to enjoy your battery for a long time.
Yeah, I think I need to set the shutoff on the inverter at a higher voltage. It looks like the BMS is going to let you drain it further than it should. Maybe that is how they rated it.
It's not even available today, hmmmm?
If it was out of stock when you checked, it's back in stock now.
who many watts total ? should be 1200 W !!!!
Yes, 1280 watt hours.
SOME THING IS WRONG !! 8000 BTU = 750 W OR 1 HP . RUNING FOR 2 HRS = 1500 WATTS AND ONLY 50% of BAT. befor YOUR INV.KICK OUT !! i do not understand !!! please explain ... from Saudi Arabia .
The inverter is at most 95% efficient. And the AC is at most 70% efficient but probably in the 50-65% range. So basing the expectation from BTU to watt calculations the results were correct.
That is why the power used was measured, not the run time of the air conditioner.
good luck !
@@mohammedmurad3787 It's an AC unit. It will not stay at 750 watts the whole time. The compressor will kick on and off and just the fan will run.
$255 😢
Sorry to hear that. The last time I looked they were still 217 + coupon but I see they have went up to 246 with coupon. Keep an eye out, it seems the price bounces around alot.
This battery is no longer $159 on Amazon.
Yeah, it looks like they upped the price. It's now $175 with coupon.
Now the price is like 217.00 🙄
You have to apply the coupon.
Still has the coupon. Killer deal.
Unfortunatly not the cheapest anymore. Up to 215 bucks.
Yeah, these battery prices are all over the place. Luckily they are coming down in price. I got a LiFePO4 battery from Amazon the other day for $150 shipped.
You can't perform an accurate capacity test with that cheap $30 Chinese made capacity testers. The results are going to get off by at least 10% to 15%. We spent over $8k each for our battery capacity testers.
Well, I am not going to spend $8k on a battery tester to test a $200 battery. I haven't found that battery monitor to be off that much. I would expect wild differences if it's that inaccurate. It's good enough for my testing. And what battery tester cost $8k anyway?
Good for you
tear it open or send it to will. these cheap batteries are always nt lipo chemistry you got scammed lol. maybe 1000 cycle lithium not 4000.
Got scammed? It's a working battery. For how long I am not sure, but it works. I just wanted to see what cheap batteries were out there and what they provide. Time will tell.
What is "nt lipo chemistry"?! Googled it and didn't find anything. These are most likely used 100ah lifepo4 cells and a cheap bms. All it needs is a $65 150a dally Bluetooth bms.
standard lithium ion battery technology not lifepo4. i think i meant to say cheap one off company batteries on online retail stores are 'not' lipo chemistry. @@1987FX16
@@1987FX16 Yeah, I wasn't sure what that meant. How do I know if they are used?
6/4/2024 at a 29% off sale $205.USD.
over priced.
Yeah, I agree. I look for sub $180 now. Prices are dropping. This one looks interesting: amzn.to/45bet2o
haha like always they jacked up the price
Of course.
Click bait
How is this click bait? Are you trolling?
