SOK Battery... www.currentconnected.com/product/sk48v100/?ref=lithiumsolar (affiliate links) Jakiper Battery... jakiperbattery.com/product/server-rack-battery-jk48/?ref=lithiumsolar Let me know what you guys think, which would you buy??
Dexter was one of the DIY guys from the earlier days and he has morphed into the new business. Sure nice to be able to talk with the seller even if it is just for knowledge and Dexter like you has lots of knowledge . Cheers thanks for the video.
I watched a video quite awhile back where a guy went to the manufacturing district in China. As he was touring he was bringing to attention the various different products being made, all on the same assembly line, had basically the same form/function, but were going to different companies, painted with different colors, etc. The way they run the manufacturing over there is pretty wild. When a company makes a request for a large order, the various different manufacturing plants will plan out the process going from one plant to another. So the end product may actually have come from, or gone through, multitude of different plants before it's finally loaded on the docks for shipping. This is also why some times you can buy 2 "identical" units, and there will be differences in the production line, because they may have actually been in different plants, let alone different assembly lines.
The extra steel enclosure in SOK batteries is good for transportation. Just received a Jakiper battery today and the batteries inside had moved forward and bent the bar across. The bar was almost touching the BMS heatsink. Fixable though and this video helped with the disassembly.
That $394 cost difference on 25 kwh kits is not showing included accessories. On the SOK kit includes 2 awg interconnecting cables and 4 feet 4/0 awg battery to load cables versus Jakiper kit only includes 6awg interconnection cables and 4 casters on the racking.
Wow I didn't even see they had that kit on their website. My pricing was based on adding 5 batteries to the cart, so it does not include the cabling. If I add the kit to the cart, it's $43 more, which brings the difference to $437 but includes all of the cabling, which would cost more than $43 if you bought it yourself. Great deal and agree 6awg is rather... small.
great video. Now seeing $1,000 difference in a 5 battery rack between SOK and jackiper.. Worth saving 1k? Seeing some shipping or packaging issues (maybe minor overall) for Jakiper.. I do like the design and design of the SOK, and seems really solid, but an extra 1k cost??
The batteires are pretty much the same as it appears one company copied the design of the other (my opinion). I'd say it doesn't matter in terms of battery performance; however, the SOK is sold, serviced, and supported by a US company. SOK also gets you an ETL listing, which may be required if you're doing something that requires a permit/inspection.
If you look at the battery report for both units, the handwriting on the measured parameters was written by the same person. Look at the 33.13, which is very obvious it was written by the same person.
Even though SOK has a California warehouse, pretty sure they are still from China. That’s what I was finding online. How about comparison of SOK to the RUIXU?
Yes, the company is from China but the difference here is they are partnered with a US company (Current Connected) and that company provides support, repair, and some of the best darn customer service you'll find anywhere selling batteries. I have reviews of two different SOK rack batteries and the Ruixu on my channel already.
Man, I clicked like as soon as I saw you reviewing these. :) I would buy the SOK over the Jakiper, but buy the Signature Solar EG4-LiFePower4 battery before either of the ones reviewed in this video. With that said, they are all very good options.
I have an EG4-LiFePower4 - also a GREAT choice. Somehow they've managed to keep the price point down AND still have the UL certifications. I guess it's cheaper to laser weld and they're also using a lower-cost BMS.
Where is the UL listing on the eg4 standard battery? Their site mentions UL listed "cells" and UL "rated" battery.. I don't see the expensive sticker anywhere on the battery though. Also, has anyone looked into the explosive potential of these things? With all the weather balloons passing over lately I imagine a twittering antennas on them sending down an encrypted messages to create a lot of sad off grid enthusiasts down below. I don't suppose the BMS software is open source anywhere..
Would have been nice if you compared the Battery stud busbars (for the main positive and main negative studs). From another video not sure if it's your or David Poz's but the battery stud busbars in Jakiper were made of Brass, which apparently is an issue if you're going to be put 5 in parallel the brass busbars, cannot handle high amperage draws without overheating. Would have been nice to know if the SOK has those same brass busbars.
Good idea. That was David's video and do remember seeing it. I'll check it out and come back with an answer. Regardless of the material, I still prefer not using the "daisy chain pass through" approach and just cabling them all to the same studs like I did in my rack demo setup.
would like to see you look at a seplos product, I have one and two cells have a strange white spot under the vent and all cells arrived a little bit swollen
You can plug the bms right into a cerbo gx with the Victron rj45 cable and it will send all bms type info to the cerbo gx automatically. If you have multiple batteries, you just daisy chain them together with a normal rj45 cable and it will send a summed data feed automatically. It was super easy.
Could we have a video where you actually touch 50v across your fingers, instead of just teasing viewers by darting your finners over contacts? After watching your video I'd like to copy your actions....but something deep in the back of my mind suggests no....don't do that! Watch the professionals do it instead.
It's the container freight making the prices high. Wholesale around $1k each until you add freight and import taxes. Now add US warehousing, employees to get them in faster than 8 weeks and a little profit for US based support. There's your mark up.
Chins doesn't make a rack battery that I'm aware of. Ampere time does; however, is only rated for 90Ah, looks like it has a low-end BMS, no communications, what looks like an AC-rated breaker (not sure on that one), and definitely no UL/ETL certifications. Not saying it's a bad battery by any means either. That's the great thing about a free market - you can go purchase the one you want.
@@LithiumSolar when I say way overpriced it’s because these server rack batteries are more than double the cost of these other brands that also contain grade A lithium cells. Nobody astute with their money will pay $2000 and only have a 100 AH battery to show for it. Server rack is targeted for rich people with a lot of money to throw away.

Let me know what you guys think, which would you buy??
I purchased an SOK 24v battery from current connected two days ago, based on your well produced review. Thank you for the videos!
Jakiper link doesn't work

You’re the best
You didn’t ramble, because your information is articulate and extremely helpful. Thank you.
You are making a important difference to the manufacturing. Your seeing as they sends out the improvements. Thanks again for your work.
A lot of the differences on the SOK are things I asked min to do. I’ll send you the PowerPoint presentation

We look forward to you testing our DIY kit.
Another excellent video buddy
🤤 I want one of each! Great video as usual 👍
Very good review. A lot of interesting detail but in a short time period and easy to watch.
Fantastic video - lots of time went into this one! I agree, the small price different is worth the SOK
Does the jakiper communicate with the SOK? Link them all up and see if SA shows each pack.
Good comparison contrast review. Well done. I think the UL listing is worth the price. Thanks for sharing
Great Comparison!!!
Nice Job on the Comparison.
Thank you very much for the review. You information is is very helpful.

Excellent... regards from Athens Greece..
Great video. I saw on Redodo they now have a server 48volt. Be interested to see a year down of that. Keep up the good works! Thank you.

in china those are manufactured in same plant, so the supervisor for qc are the same, or they just copy those papper

HOWdy L-S, ...
Thanks for the REVIEW

Would both of these have DC circuit breakers.... or are they actually AC circuit breakers, not suited to 50V DC operation?
Would have been nice if you compared the Battery stud busbars (for the main positive and main negative studs). From another video not sure if it's your or David Poz's but the battery stud busbars in Jakiper were made of Brass, which apparently is an issue if you're going to be put 5 in parallel the brass busbars, cannot handle high amperage draws without overheating.

This feedthrough connection on the SOK is spec’d at 310a max. David was also using undersized wire in his video.
would like to see you look at a seplos product, I have one and two cells have a strange white spot under the vent and all cells arrived a little bit swollen
thank you for shering
Do they communicate with each other?
Are they the same to setup and program?
Perfect openning vidéo 👍
Do you Knox if these batteries' BMS are communicant with VICTRON ENERGY MULTIPLUS OR QUATTRO ?
have a look at the Current Connected website site. Full user manual for the SOK is there.
You can plug the bms right into a cerbo gx with the Victron rj45 cable and it will send all bms type info to the cerbo gx automatically. If you have multiple batteries, you just daisy chain them together with a normal rj45 cable and it will send a summed data feed automatically. It was super easy.
wow nice i think i would like to buy it
can you please mention the possible use of dry contacts as alarm or load management?
The only use that immediately comes to mind is for starting a backup generator when the batteries are depleated.
Great！Professional Introductions！Welcome to visit our factory of Lithium battery manufacture.
Yes akb🔋 ⚡💡👍
Wow both the same price, i was sure the jakiper would be cheaper
jakiper batteries have no reason to be so much more expensive than all other 48v server rack batteries!
What we really need is a review of the various dealers CUSTOMER SUPPORT! Spoiler alert, they all suck!
Current Connected are amazing. Give them a go.
Current Connected certainly does not suck in the support department. I can't recall ever hearing a single person complain about their support.
If it looks like a duck and quacks like a duck, it's a duck.......

we went wth SOK
Good choice I thinks!
Interesting... shipping to the UK ?
I live in the US, I have no idea if they ship to the UK - ask them.
@@LithiumSolar OK... tks
@@houseofancients Thanks
Two brand may from one manufacturer factory in China😂

Both way overpriced

@@jstaffordii I’m comparing them to Ampere or Chins who also face the same overhead costs.

@@JamesAmbrose48 yes they are 100ah but 48v which gives you 5120 watts and go for around $1450-$1700
