That quality, at that price, is mighty tempting. Thanks for the teardown! Edit: Lord almighty, that was an exciting bit of action when you tried to slide it in the first time! Impromptu spot welding attempt.

I will always appreciate you being willing to show your failures and your own mistakes and nearly always using it as an opportunity to educate. Not all folks doing these types of videos would be humble enough to do that.

YES!! It's a great battery, even picking it up it just feels more "solidly built" than some of the others - it's hard to describe. I'm glad to see the rack finally. I had a picture but they were still finalizing the design of it when they sent me my battery. The lack of a circuit breaker is a bit of a bummer. It didn't care at first, but the more and more I work with my system, I'm finding it to simply be an excellent way of isolating a battery or batteries while working on things. I mean, I guess the amphenol plugs make up for it - simply yank one off.

I will say that Will demonstrated the worst case scenario and why a T class fuse is a very good idea. Using a mega fuse, I would be interested in seeing if it would actually work with that many surge amps behind it. I haven't blown a T class fuse yet, but I do have spares just in case.

I purchased an EG 4 server rack system with six batteries several months ago and the new cabinet has a door that latches and locks, very nice heavy duty wheels with locks, it is completely welded, it is a very nice cabinet. Somewhere I ran across a video stating that they have greatly upgraded their cabinets. From what I received versus what some others have I would have to agree that they are greatly improving them.

This is good to hear! I'm looking at the EG4's right now myself....

Will pointed out exactly what I was thinking about this company throughout the entire video - "I am WIll Prowse." If Ruixu sent this hardware to Will, what are the chances that Ruixu made a point to ensure the hardware was as close to perfect as possible? It's not unheard of for a company to send review units that are pristine, only to have the actual consumer product ship with poor quality construction.

@WillProwse

10 ай бұрын

That used to be the case with the 12V packs. But I'm not sure what they would change in this pack to lower the quality of construction. If they have the cell terminal welding machine and proprietary cell holders for the cells their using, and it's listed, it would be very difficult to make a "different" product for KZreadrs. Also, anyone can open this in five seconds. So if that's the case, we will know quickly.

No matter what, first production units are likely to have more attention, then manufacturing is likely to have issues shortly after startup, then those issues will typically be improved. That may be part of what happens too. In addition, what Will said is true too, they are much more likely to provide him better service than we mere mortals.

I agree with your comments about the design of the server rack. Having the cables routed through the top seems like a good idea. The over/under network connection is good idea also. That said, I don't like the on/off switch being located under the negative cable. You should not have to move the wires to turn the battery on/off. The on/off switch should be somewhere in the center face area to make is easy to reach and operate.

Great review. It is good to see more rack mount batteries to up the level of competition.

Will, so very impressed with your knowledge and success

Will Prowse the mad scientist! Thank you for the show 😉👍

Cool. Price seems good but including shipping and the waiting/delay I will stick with EG4 for now.

@@KyleSindlinger Sol-Ark 15k. Only time will answer yor concern. So far, Ruixu has been very responsive to every question I've asked. Since they originally released, they've also extended their warranty from 7 to 10 years. I'm also told their UL9540 Certification is due out very soon. I've paused on my next purchase to see if their new 14.3kWh battery bank will communicate seemlessly with the existing Rack systems. If so, I will likely go in that direction since the form factor is so much more compact. Specs and pricing should be released shortly.

Looks like a nice unit; looks like it actually has a standard rack height too (the EG4's are about 3.5U which can make them akward to fit, this looks like it could be 3U on the dot)

RUiXUs are a much cleaner build and more compact when racked vs the others. The space saving in itself would be great to have a 4 stack in a van. I currently have 4 SOKs ready to be installed in my van with Victron MultiPlus IIs in parallel. Wish this came along sooner.

Can you do a video of using a server rack battery in a van build?

I so agree with you on the SOK batteries. If they had a nice cabinet that could hold 6 batteries and looked good they would be great, but because I get one free battery by buying the EG4 there is no contest. I sure wish Will wold have just tested if an EG4 battery would fit in this rack because they will sell that rack for $559 and those EG4 batteries would sure look good in that silver rack.

I just bought the new RX-LFP48100-H

The quality of all these products has come up so much that we're now reduced to complaining about whether the cables look good or not; or speculating about the future prospects of the company. Well Done @WillProwse!

Wow, I might consider this for my 30k off grid system I plan to build soon. Thanks! Will you do a capacity test?

Will, you are supposed to save fireworks for the 4th of July!!! 🎉🎉🎉

I like that they are offering their rack separately - with no requirements. Both EG4 and now SOK require that you've bought some of their batteries or they won't sell you a rack.

Love ur vids, always so much info! I've been trying to upgrade my RV batteries and have been scouring aliexpress, any suggestions? I wanna fit 15-20kwh at 48v with a 240 outlet outside to run a welder😅 but Im nervous about vibrations and you know...death 🤷‍♂️

Thanks for the demo and talk. I'm just not clear as to why exactly the short occurred - even going thru the video frame by frame does not show the problem. Would be nice to know exactly what went wrong.

Enjoy watching your videos, how do you set up the EG4 18K to work with the EG4 Powerpro and the Ruixu batteries? Do they both have the same settings?

Should they move the power switch to not be under the wire? Was the short caused by the handles touching the terminal? If they added circuit breakers and move that power switch it seems like it would be perfect?

@WillProwse would you recommend a rack style battery for a Sprinter van (full time)? Thx, Matt

Great video as well. Going off grid soon too. I have also some spare network racks like yours that I will use. Since EE I will have a braker or fuse between bus plus bar and inverter, just in case (and I can turn off the whole rack). May you come up with an solution as well?

19" everything!

Will, what lift table are you using, where did you get it ? I’ve been trying to find one that lifts high enough for the eg4 rack.

Great video... thanks. Just noticed that the bottom battery lights were not on or flashing in the rack near the end of the video... did you possibly not turn that one on? Just curious. Oh, and that short circuit sparks would have scared the s**t out of me. Please be more careful.

Famous KZreadr saying: "At least we got it on film!"

The quality on server rack batteries are getting better and better together with the price. However, a DIY battery is still much cheaper so that's still my preferred solution. personally I will only pay around 15-20% more for a prebuilt battery compared to a DIY one.
