[@stefankaufmann8257]

Andy i wouldn't worry about the voltage specs. The primary use is switch, not circuit breaker, because the BMS takes care of any overcurrent. As a professional industrial automation guy i would prefer a more sophisticated overcurrent protection, but this configuration works as well. 50mm² is good for 200A continous current, if the leads are 1,5m long and it's ok for 275A trip current. It could be thicker, but all in all nothing wrong with that. And yes, the box really seems to be of outstanding quality, not only regarding the design, but also the manufacturing. All screws accessible, beefy metal sheets, middle rail, nice busbars etc. That's really impressive.

[@cordebakker5513]

I have ordered 3 of these and a set of rollers. Currently the best 48V horizontal box out there. Only improvements I can find is an extra plate for fixing the BMS board to avoid cracks induced by the deformation of the compression forces, and a better circuit breaker so the cabling and batteries are also protected by this breaker. Thanks for the good work Andy 😄

I think it’s a lot better than the one I just bought. I purchased a box with a JK 200 amp BMS and it’s been a nightmare. Yes this is my first dyi installation but they could have made it a lot easier. First the 3 inch LCD was cracked and unusable second no matter what I did I couldn’t get any voltage to the external terminals. Building it was the easy part setting it up to work impossible. My mistake was not knowing the BMS that I was getting. I suppose there is a chance I damaged it when installing but everything except the SOC LEDS and no power out. Great job Andy.

On small DC breakers you have only one direction where the arcs are distinguished (Funken lösch Kammer). DC should break plus and minus pole. (1x 275A breaks both poles). Charging is only 50A, discharging can go to 10kA when the inverter would have a short circuit.

[@jackoneil3933]

At 9:05, I wonder Andy if they Are they using the dual pole breaker contacts in parallel to double the Interrupting current capacity of from 7,500 amps to 15,000 amps to meet the potential short-circuit inrush current potential of the battery which may be at least 10,000amps? My thought as to the 550A overload trip current possibly being too high for the design might not be major issue, as it is in sires with the BMS that provides some level of overload protection, and the breaker is serving mostly as short-circuit protection device, and as you suggest serves more as an 'On-Off' switch. As for the sizing of the conductors going from the BMS to the breaker and out to the terminals being undersized for 550A continuous current, again you have the BMS to limit current and the breaker appears to be function as short-circuit protection, and limiting the size of the conductors to the intended max current of the BMS, may help in reducing potential short-circuit current giving the breaker a better chance to interrupt a short circuit without damage or failure to the breaker itself or the BMS. As for the the breaker line-load connections, and the circuit being bi-directional, from what I recall about Circuit Breaker design, current direction may have more to do with meeting short-circuit current interruption rating and the design of the contacts being able to meet spec in one direction more so in the other, and in the case of charging you also have the BMS and the undersized conductors that might may limit maximum possible short-circuit charging current to less than the breaker's designed ICU.

[@david0alinda]

The way they used this breaker is NOT ok. You cannot "stack" Ics values as it will be a lottery as to where the bulk of your current goes when in parallel. Even a tiny amount of resistance difference between the poles makes a huge difference in current carried. Next to that, with DC-breakers, the directionality has to do with arc suppression. It says on the label "mount vertical" which is because of the suppression chamber being in the correct orientation. As this one is mounted, only when charging, or with a short INSIDE the battery in a multiple battery system, will the arc be quenched in a correct way. When the short is outside of the battery; better not to have any body parts in close proximity. This also answers the question af another poster here about being able to mount this box on it's rear. By the way, kudo's for the CN manufacturer for labeling this breaker with relevant information. Many leave lots do be desired. In short: opening DC-currents is a very tricky business, and this one has gotten it wrong. The only way to use this box safely is to have a correct T-class or NH fuse in close proximity to the connection.

The housing is quite ok. But not 5 out of 5 frogs. Maximum of 4 out of 5 frogs! Problems: 1) I only had two screws per balancer rail and no plastic washers. 2) The flexible busbars are only 40mm² including the ones to the BMS. 3) The two plates that connect the circuit breaker are only 18mm². 4) The circuit breaker can only disconnect 10kA. 5) The screws of the circuit breaker only have serrated lock washers and no spring washers. 6) The screws of the circuit breaker are only M6 and then also with a spanner width of 11mm instead of 10mm. 7) There is no IEC62619 certificate, but this is required for registration with some network operators in Germany!

[@universeisundernoobligatio3283]

The dual breaker is actually 2 110 amp breakers in parallel. Ideally you only need a breaker that is 120% of your max inverter current. Also if you are using multiple battery boxes each battery box breaker can be a much lower current rating.

[@dennisvandenoever2963]

Hi Andy, just to comment on the circuitbreaker. Icu of just 10kA is not very high considering the shortcircuit current that Lithium can make with the very low internal resistance of the batteries. Best would be to have like Class-T fuse which can handle like 50kA

[@jeeastee]

Hi Andy, Thank you for all the information you share. I see the breaker has an ICu of 10kA, but a lithium cell has an internal resistance of approximately 0,15 milliohm which can cause a short circuit current of 3,5/0,00015 = 23kA. So the breaker could arch while tripping on short circuit. All the battery boxes I find have this same issue and it's a major safety issue I think. How do you think about this?

[@peterdiy]

Don't forget the busbars, connection to BMS and BMS itself. The resistance will be a lot higher, the current a lot lower than what you got. Plus the BMS has over-current protection.

[@jeeastee]

@@peterdiy Yes it has overcurrent protection, but the breaker must also function when the overcurrent protection fails in a full short circuit situation.

[@tmarbut]

I've been wondering the same thing. I suppose we could approximate the resistance of all the bussing and connectors, but I agree the breaker is definitely insufficient if we disregard those resistances. It's very hard to do proper interruption for these 280AH cells, and I wonder whether the UL listed server rack batteries or wall-mount batteries that use 280AH cells (like the MidNite Solar, EG4, and SolArk wall-mount products) are actually able to interrupt their maximum short circuit current. If they are, I'll bet they are also assuming that a great deal of the resistance is in the bussing and connections.

[@peterdiy]

@@jeeastee Yes, but the breaker is not installed on the naked cell. Even just the welded on studs add resistance. For cells tested at factory with 0.17mOhm I was told by the seller to expect about 0.20mOhm measured on the studs. By the time you include the bus-bars that will be a lot more again. As a result the maximum current the breaker ever will see and has to break is a lot lower. 15kA or less.

[@jeeastee]

@@peterdiy Your right, but still I would like to see a test of the breaker in short circuit without BMS protecting for overcurrent multiple times without exploding or arching, especially when it is a breaker from a unknown brand without test certifications. I decided to buy a box without breaker but with a emergency switch and I will add a 20kA T-Fuse myself.

Maybe the really long cable at the screen area is meant so you can have the boxes sitting far away and the screen on your desk...

yeah, these original JK- cables are for that purpose, not for the 16S-boxes ...

Where in USA can purchase yixiang battery box?????

[@tujuprojects]

Did you solve the missing data problem already?

[@putteslaintxtbks5166]

I would guess that braker is as stated for both together as is. In the US we have both 110v and 220v and alot of brokers are double for 220v and if marked, say 40 amp, if taken apart, it would be two 20 amp brakers.

[@caesarvalenti2763]

I do not think this is right since the current must go thru both sections...so if it says 40, it is 40.

[@OffGridGarageAustralia]

Yeah, we just don't know. It is usually per path.

[@ThaTySkiE]

Is it possible to order a battery box without the BMS?

[@DukeEast]

Pretty Interesting Box Andy, One question in mind, Can the Box stand 'Vertically' ? I mean can you he rollers be mounted to the smaller Back ? And not the Base ? Cheers mate

[@OffGridGarageAustralia]

At this stage I would say, it can. The frame has plenty of strength to cary the cells in a vertical way.

[@JoeInBendigo]

Not sure about your voltage comment. I suspect your 48V battery will be in trouble if you feed 80V in and you're not likely to get 80V out either, right?

[@OffGridGarageAustralia]

At the end, that's what the BMS is for. If I feed 80V from solar into the batteries, it will still charge as usual, as much as the solar can deliver. The BMS watches and will disconnect if out of spec. But will the BMS still work with 80V on its input?

[@LordOneHoop]

@@OffGridGarageAustralia No 70V is absolute maximum according JK specs.

[@brucebugbee6604]

Andy nice looking battery box and review. I noticed that the negative and positive terminals on the front panel were on the opposite side from most rack mount batteries that I have seen. I noticed when you were loading the cells on the right side of the box that you were putting them in the box with the most positive terminal to the outside of the box. The BMS positive busbar looks like it was designed to connect to the front cell inside terminal on the right side. Also, if each breaker pole is rated for 275 A couldn't you just use one pole of the breaker to reduce the over current rating of the breaker by removing the paralleling bus bar on the battery side of the breaker to split the poles?

[@diyEVguy]

The 275A applies to the pair, see also the description.

[@davidpenfold]

That is one sexy DIY box ❤️

[@davidpenfold]

Hi andy do you let the communiti know if there cerquit breaker is up dated ? I think this is the box that i want for my battery's.

As I said in the video, use an external proper breaker and use the built-in one more like a switch in case you need to disconnect.

Hi Andy, I have just found your videos and they are great. I am building a battery pack using the EVE MB31's that you tested with good results. My problem is that none of the XiaoXiang BMS software APPS available for my android phone allow me to change the parameters of my BMS. Do you have any advice please?

[@OffGridGarageAustralia]

Why is this a scam? It has different options. You choose the one you want.

[@tujuprojects]

@@OffGridGarageAustraliayou answered to wrong question. 😮

[@LordOneHoop]

@@OffGridGarageAustralia Yes it certainly feels like a scam. YIXIANG advertise stating it is for 24 volt systems also but they don't have 24 volt DIY boxes. And as far as i can see the JK Inverter BMS JK-PB2A16S-20P (same as they put in) with breakout box i bought won't fit in an empty shell box. They do not have 24 volt pcb's so in fact it is only for 48 volt. Complete box with all included except cells delivered to the Netherlands for 538 US Dollars. Empty box with nothing still 220 US Dollars. You pay 120 US Dollars to get from a eurowarehouse in Poland fcol! Bummer!

you are right. just checked. my JK boxes did not have .... bought too early ..... but for my purpose with the insulated box the old version was better....

Our horizontal JK battery box was launched earlier than theirs. The new screen kit uses 4 flexible busbars and the shell material is also better.You'll see it in Andy's review video soon.

Is it OK to not have any fiber boards between the batterie cells and the bottom of the case, or between the sides of the battery cells and the case?

[@boydw1]

@@mandimandi2523 Thanks! I was planning on the JK BMS anyway, so that looks perfect.

[@OffGridGarageAustralia]

Most 24V boxes will fit the same number of cells but installing them in a 2p8s configuration. You can basically use any of the 48V boxes and arrange the cells accordingly to make a 24V system.

[@boydw1]

@@OffGridGarageAustralia Thanks - Yes I'm aware that I could configure the 16S boxes as 8S2P. That would be too large (and unnecessarily expensive) for our RV application. The Eel 8S box looks suitable.

[@EnergieStroom]

Hi Andy, respect for your topics, I am now also ready to build a 15KwH battery box. I live in the Netherlands, batteries from EVE mb31 and the JK BMS is no problem and can be ordered via NKON. But this battery box is difficult to obtain in Europe, which is very strange to me, just with impossible delivery times and extreme shipping costs. If anyone has a tip on how to obtain this cheaply in the Netherlands, I would be very grateful and so would many Dutch people. Greetings Eric

[@danielardelian2]

Some DC circuit breakers use a magnet to deviate and extinguish the electric arc that forms when breaking the circuit under load. This works only if the current is flowing in a certain direction. If the current flows in the opposite direction, the arc does not extinguish and the circuit breaker could catch fire. There are many demonstration videos on youtube about these "directional" DC circuit breakers frequently used on solar panel circuits.

[@PersonalStash420]

Is that what this box is using, a magnetic breaker? Is this box unsafe, in your opinion? I was thinking about getting this one but I would need to stand it vertically to fit in a small closet. Is this a bad idea? What do you think? Anyone may answer, btw. 😀

[@danielardelian2]

@@PersonalStash420 Breakers with magnetic arc deflection have directional markings for the correct current flow direction. This one with an input and an output marking is suspiciously similar.

[@RobinRastle]

@@danielardelian2 Indeed yes only works on battery output not for battery charging - separate MCB needed. But then the main danger is battery sc with down stream inverter etc. Nvere forget the ultimate breaker is some big cable cutters hung permanently beside the box - leccy pliers wont cut it.

[@BarthoDeGroot-jx4tm]

Can this bms and box be configured for 24v?

[@davidpenfold]

No. But they also do 4S-8S boxes.

Moin Andy, Rainer aus dem sunny Norddeutschland hier... Ich habe mir tatsächlich die Xixiang battery box zugelegt. Als 2tes Pack. Ist aber noch nicht da. In discord bei meine Energiewende wird hart diskutiert das wenn man 2 Packs mit dem JK BMS in Benutzung hat, werden keine Fehlermeldungen an den Cerbo GX weitergegeben. Bei 1 Box funzt das ohne Probleme. Hast du das Problem bemerkt? Ist es dir schon aufgefallen? Falls du, was ich mir sehr wünschen würde, nachstellen könntest und eventuell JK diesbezüglich einen Hinweis zukommen lassen könntest, wären einige YT Gucker sicherlich sehr glücklich sein. Wie sieht es aus? Können wir auf deine Unterstützung hoffen? LG Rainer

Hi Andy, a double pole breacker normaly isn't two breakers at once. All the current sensing part loke the bimetal strip is only in one of the two lines. The only thing which is double are the contacts to separate plus and minus. So amp rattings aren't doubleing up.
