[@krissfemmpaws1029]

Yes it's not flying high with the capacity tests, but what you are getting for the money seems to be reasonable. Something to keep in mind is all the cells are built to a given tolerance plus or minus X so they meet nominal rating.

It's strange that prices haven't gone down like in Europe( 5kw $670 for a rack battery) .I think they are preparing for a 10% tariff.

[@AdityaEnergySolutions]

That's the only right answer

[@spookydonkey2195]

It’s tempting for sure. I agree with capacity value 100% but the inconsistency of the cells is worrying in the long term. I have to buy a few SR batts soon and will definitely be keeping an eye on these. 4 for the price of 3 is hard to argue

I understand why Will holds them to task in truth in advertising after all they said it was a certain capacity and in a couple cases didn't meet it. But I do think its funny he makes such a big deal about it and acts like a product is unusable because its missing 1.5% of its capacity. For a 30-40% discount that sounds like a good trade to me. Shouldn't be discharging it far enough to matter anyway

[@Ricardofromage]

Ecoworthy had some poor reviews early on about bms failures, a bit hit and miss, I've followed their products for the last 3 years while building overlanders. They seem to be really trying to shake their early image, they've got some good kit out there for ridiculously cheap money, I ended up going for two of their 25.6v 100ah liFepo4 units, so far they've been faultless but I'm only 9 months in, time will tell, but i managed to get those batteries at a ridiculous £350 each other ebay deals.

​​@@RicardofromageI have 4 of those batteries and their hybrid controller... It's worked flawlessly so far (since Nov ish 2023) It's primarily for ups failover on my furnace, network and deep freeze so it has had limited use, but so far, no issues

[@Ricardofromage]

@@marcjampolsky5280 good to hear, to be honest, if mine only lasted 5 years at 700 initial outlay, that's obscene VFM, and that's at worst case scenario with poor cells etc. I've used victron for everything else as I like the app and wealth of stats and info etc, and that all the components "talk" to each other. But when I buy land later on I will be looking at ecoworthy's 48v inverter/charger/mppt unit for sure, it's 450 quid. That's 1/5th the cost of the victron equivalent, and I've seen a couple of videos on here of Canadian off grid cabins that have had them installed for 2 years now, zero issues or downtime, I keep going back to check periodically 😂 They honor their warranties and have tightened up after sales service a lot, interesting company to keep an eye on.

Thanks Will for posting this video. I have been looking at this battery too. In fact, on Ebay some winning bids are at $750 but you never know if that is just a corporate shell game. The BMS I believe is a BYD and of course welded cells does cause concern on serviceability and/or wonder if the company will honor the warranty without a hassle. Maybe Signature Solar is watching too and asking themselves how can WE produce a competitor to this server rack battery? I like the idea of the screw top to replace a cell. But to be honest, the ONLY reason I was considering the battery was the price point but being skeptical I have not purchased it. But if I pull the trigger, I will use your coupon code!

[@erikj9962]

Or the cells are truly a bit lower grade... the price point though is great on these and certainly warrant a closer look!

Thank so much for your work! You are wondring about the "strange " pricing of this battery. But perhaps this is just the wonder of the invisible hand (which thankfully also weaves over china). If lifepo4 cells are falling two digit percentages each year, some sellers are deemed to be the first to reach down into new lows while others are sitting on the fense and reaping an extra profit. But eventually all will have to adjust. Just see where prices where 2 or 3 years ago. Of course there are LOTS of bad actors out there we need to guard against. And this is whu your work is so important.

[@bandido6507]

It works good in my system. The price was great, but I really like it communicates perfectly with my Victron Cerbo across the CAN-bus. I can remotely check which cell is high and which is low for both units. I have 2 of them communicating with each other across the 485 port. 1 set as the master and 1 as the slave.

These are 51v, so more than 4x the capacity

[@greylocke100]

Have you done any testing of nickle iron (Iron Edison) batteries?

[@CBRR10011]

Question have you ever reviewed lithium battery Werchtay 12v 100ah

[@Time-Trvlr]

Some of the other budget models do not have comms. The other contributor to differences in charge/ discharge could be variances in the BMS manufacturing.

[@d.thomasmeduri9105]

Please test the Vatrer batteries, I’m anxious to see how they compare since they’re very close in price. Thanks

[@HuyTran-zy9sv]

They just introduce the 48v 280ah battery. I just saw it on slickdeals

[@jamespurser357]

Purchased 8 for my off grid home a week ago. Now i want to test the capacity of each one. How do i do that?

[@Tumbleweed5150]

Watch any of Will's battery testing videos where he does a capacity test. It should be the same for these, but done on each of the batteries, so will take a lot of time.

[@selenakb1077]

What do you think about Felicity batteries?

[@1932cheytruck]

Will , isn't there a fairly new NC factory producing graphite battery's here in the US (NC I believe) they be heavier but but fine for solar an allow people to buy battery's here in the USA maybe save shipping cost for builds , but I was wondering if you have found ANY American company building server rack batteries with these USA made batteries and how they price/test?

[@MrEagleeye58]

Tariffs kick in soon.. You should do a price review.. Am sure fire sales will start claiming prices will rise tremdously. People have to be careful.

[@MrButuz]

Could it be an economical BMS settings Will stopping it from getting the last few % by cutting it off early to increase cycle life? Be interesting to see the cell voltage at max charge and at minimum.

[@rob4334]

Will love your videos what do you do with them when you are done do you trash them or sell them thanks

[@solera-electric]

cant wait for these to be available in canada

[@michaelconway4316]

Newbie here! What's the advantage of a server rack battery over a regular LiFePo4 battery? This still seems too expensive compared to running two 24v batteries in series to get the same capacity? Thanks!

[@Zoned9]

Thanks for the review!

[@thefaeryman]

do ever test the tesla power wall?

[@ericwilliams952]

Yes we love that battery.

[@Laserguy2009]

Time for a new Solar Kart!!

[@agwatcher]

Using non-rack 8x50ah pack of them for now. The price is really reasonable unless you want to be super pedantic perfectionist. The first batch I bought was really perfect, the second felt that they are selling a lot and are overwhelmed, e.g. packages contained either only red or only black connector shields. So, that raises a question of internal assembly quality between the batches.

[@ericferguson1062]

I am having flashbacks of the old days, expecting you to pull it apart cell by cell to find the faulty one in the pack and get full power. Sounds to me like they are mismatched cells

[@davidtreichelpppj5304]

Can you make a video on These Battery Storage Facilities ?

[@davidtreichelpppj5304]

Hello Will , I live near Moss Landing Battery Storage Plant ... What do you think happened here ? And the future of Battery Electrical Storage ... They took a gas fired offline for this ? Is it a scam like EMRON debacle ?

[@diydarrell3196]

So...does it communicate with the 6000xp?
