Wow! Thats approx a $600 total cost build for the box and cells for 300+ Amp hours. Thats half the price of some of the top of the line Epoch 300Ah batteries. this is a great box for us sailors who would like to build our own simple 12 volt batteries but also want to have lots of control through the BMS or to be able to upgrade the cells as newer and better ones become available or get damaged. So excited. I might get a couple of these instead of buying batteries already assembled which can be a real pain to quickly and easily service. Lightning strikes are a real danger for boats and can quickly destroy a BMS. It would be easy to carry a spare or two and replace them on the go if this ever happened in the middle of an ocean. Great stuff! A remote display would be an absolute dream to have in addition to the bluetooth. 🐸🐸🐸🐸🐸

[@davidspeed1951]

Edit: New Info Available ... Looks like competition in this market is heating up. Prices on the kits seem to be all over the board. Some decent deals on 24v boxes through CNEEL iirc on Ali. The EEL box -seems- to discourage setups for series (2 x 12v = 24v) operation. Original comment: I too had an interest in a 24v system to power a remote link to my ISP. Looking at prices, it looks like you can just build 2 12v boxes for the same price and get additional flexibility. Also spend capital in smaller increments.

[@olafschermann1592]

Temperature sensor is best suited between 2 cells. To accomplish that either under an EVA tape or milled into the epoxy plate (if it has the same thickness)

[@OffGridGarageAustralia]

The sensor is too thick for either. I have seen people printing thin 2mm plastic spacers which have a channel for the sensor.

For safety, would also like to see some kind of protection on top of the BMS so nothing can short pos/neg. 4.5frogs and your point of having a spare red/black cover was good as well. At approx 5:24 you mention 2x 6gauge wire for BMS to terminal. Was that really 6gauge? not 3? or 1/0? 6gauge is for about 55amp continuous so that's undersized for 200amp BMS.

Lots of boxes ticked here. But the fuse-to-cell conection is terrible. If mine, I'd put a 'tinned' copper washer with tight 6.0 mm hole, at least under it, maybe on top as well.

[@OffGridGarageAustralia]

What do you think is terrible with this connection?

[@raystone4673]

Hi Andy, love your shed. I think your original doubts about those welded studs contact area, was well founded. Even if your tests showed no local hot spots, that flat surface on the cell is not ideal for a high current to pass. They could have used more area of the terminal base, and welded a bigger area stud. Your magnet test once said it's steel, and so about 18% as good as Copper, or 30% of Aluminium. If you had a tinned copper lug, bigger in area than the stud, with a 6.00 mm hole in it, (not 6.5 even or 1/4"), that would be the way to make the best of a bad cell design. The fuse with a slot that is 8.5 mm wide, and much longer, results in very minimal contact area. The tight red condom covers on the fuse may reduce rating? I know these later, high cap cells have reduced recommended current specs, and your application won't push them. I've ordered some EVE-LF280K- HSEV from Gobel, for EV application with the optional double-screw thread terminals. The 1C contin/ 2C pulsed rating means 560 amps for 30 secs discharge would need everything going for it. They wouldn't fit in that box because of height I guess.

Nice kit. I would love to see a 12v battery build suitable for house/leisure bank in marine environment - I.e a sail boat. So a plastic enclosure rather than metal if you get the chance to try something like this.

Loving your channel. C'mon 90k!

[@OffGridGarageAustralia]

Thank you. There are lots of options for 12V LFP batteries out there. Some are supposed to be IPx6 rated but they don't have JK-BMS. The BD series of these 12V JK BMS cannot communicate among each other, they are pure standalone devices. However, there are some solutions out there where a Raspberry Pi collects all info of the individual BMS and combines them to either send to an inverter or just for data analysis.

[@athertop]

@@OffGridGarageAustralia the other option of course to increase capacity to say 600Ah is to series 4 blocks of 2 parallelled cells (in each block), so only one bms used. The cheapness factor still leads me at looking to build with eve cells in some sort of plastic enclosure. Winston cells would be nice but far too expensive for my small wallet. Maybe I will have to build a fibreglass enclosure. 🤔

[@athertop]

I also meant to ask the community here. What takes presedence if you have an inverter/charger (let's say this is Victron multiplus) and mppt/solar both wanting to charge your batteries? If both the mppt and inverter/charger are Victron units will they use comms to give priority to solar to save on grid power? Or aren't they that smart?

[@irfansensoy5901]

Hello. I bought 16 EVE 280AH batteries 2 months ago. I also procured JK-PB2A16S15P bms for these. I installed it and have been using it for 45 days. My cell number 14 started giving unstable voltage values. While it is not visible in instantaneous currents around 15-20 Ah, it shows a higher or lower value than other cells when drawing or charging energy above 25 Ah. For this reason, I cannot charge and discharge properly because the BMS reaches the lower and upper limits set before the others. Especially during 40-50 ah charging, when the cell sees the upper limit value of 3.5 volts, the bms limits the charging current to 10 ah and this continues until I restart it manually. Is it normal to see abnormal values ​​in cells in such a short time? Additionally, the charge and discharge current limitations on the BMS do not work at all. The hybrid inverter I have tries to charge the cells without any limitation on how many amperes it sends. What advice would you give? Thanks.

[@OffGridGarageAustralia]

Definitely not normal. I doubt it is a problem with the cell itself. Most likely a connection issue. Swap the bus bars of this cells with some others and see if this makes a difference. If not, swap the cell with another cell and see if the problem sticks with the cell regardless of where it is mounted.

The EEL 48V box is next on my list. The double 6AWG wire in the 12V box is good for 150A. As it is short and not many people will push for more than that continuously, I think it is OK.

[@Chris-ut6eq]

@@OffGridGarageAustralia If it does not meet rated capacity, it's not ok. in USA 6awg is only good for 55amp continuous. This is a problem. If someone wanted to push it to 200amp, this is a big safety issue. Does not matter if only 1percent of people want this. the BMS is rated for 200amp continuous? Did they upsize the BMS but not the cables? I think in your video, you said the fuse is 250amp? This is red hot fire territory for those cables. Safety is to manufacturer rating not how many people push up that high. Trying an outdoor test pushing 200amp through the box. Would make for a dramatic video. I was getting close to buying this but they seem to have cut corners that can harm people. Curious where you get 150amp number? What I can find online says 6awg is 55amp. Am I missing something?

[@OffGridGarageAustralia]

@@Chris-ut6eq I'm using the Jcalc website for Australian regulations. 6AWG is 16mm cable, good for 72A. Being a very high stranded wire with silicone insulation, they can cope with more. There are tables online for these cables. The length of the cable and how much air flow it has plays a role as well. So 80-90A if not 100 should be possible. The BMS is 200A, the breaker 250A and we have 2x 6AWG cables, so at least good for 150A. I'm not too concerned about it as we never push continues 200A through the BMS and the battery. In case of a short, the BMS will shut-off, if it fails, we have the breaker. www.jcalc.net/voltage-drop-calculator-as3008

@@OffGridGarageAustralia If you are comfortable with this for your personal use, based on the assumption you will not push more than 140-150amps through a device claiming to support 200amps, that's fine. Anyone else using this should look at their national electrical code for amperage guidance. In the USA, for copper core 55-75range is possible depending on the type of insulation. Keep in mind the higher amperage means the cable will be putting off ALOT of heat at 150amps, that why the high heat resistant insulation is needed. IF someone does not pay attention and tries to use the full rating of the BMS (200amps), this wire is a fire hazard. Depending on the wire to burn through and short out to trip a breaker means you are already in serious trouble. The internal fuse sized at 250amps is not helpful either. I assume the BMS default limit is 200amps? Also the fact this is in an enclosure also would mean some derating should be considered. Anyone reading this, use the NEC (National electric code), see if the cable including has any markings for meeting cable insulation standards (they look someone like this in the USA, TBS, SA, SIS, FEP,FEPB, MI, RHH, RHW-2,THHN, THHW, THW-2,THWN-2, USE-2, XHH,XHHW, XHHW-2) Then look at the guidance in the NEC for enclosed use poor to middling air cooling. If your personal use case aligns with the current capability of the cables, be sure the BMS and internal fuse also work for intended amperage. As shipped this device IS a fire hazard at it's 200amp rating, using the 250amp fuse. Never depend on external breakers for what's going on inside the battery box. Breaker sizing is whole other thing as breakers have ratings for AC/DC and timing curves with ratings like A/B/D/etc which determine trip times for resistive/inductive loads. A external breaker is protecting things outside of the battery box. In the USA, consider using a good quality copper 3/0 gauge or even 4/0 if you want to get 200amps to power a 2000/3000 inverter. If you want 150amps, upgrade to 1/0 or 2/0 and change out the internal fuse. Be sure you get a high heat insulation rated insulation for safety. In general, don't be cavalier with electrical safety. National electric codes exist because people have already died when things went wrong.

Some holder would be nice?

Great looking battery box... excellent review as always! The dimensions show 383mm for length, is that the box or to the end of the teriminals? I'm looking for something to fit under the seat of a 2022 Fiat Ducato.

[@mandimandi2523]

be careful with the size. ask them first. the dimensions at the 48V-box are just for the box.... thats not very smart from EEL...

[@OffGridGarageAustralia]

Yeah, just the length of the box.

[@panospapadimitriou3498]

turned whole warehouse lights to 12v DC ////13.2v to be precise for all led lines and all i see is efficiency goes bad . i did this to avoid inverting from 48v to 230 and back to 12 but conversion from 48 to 12v still demands big ammounts of losses!!!! any thoughts of sending 230 and installing ac to dc right close to the leds ...or let it be ? ?

[@OffGridGarageAustralia]

It is the long 12V runs which cause the issue. Current goes up and efficiency down. It's probably better to run 230V to each light and have the driver connected to the LEDs. I think, that's the most efficient way.

[@panos8444]

Beautiful, 12volt, 2S4P ( high capacity 12v) how to balance? Best BMS? etc

[@CollinBaillie]

The JK BMS included does the balancing. It has an active balancer built in.

[@OffGridGarageAustralia]

Yep, go for the JK-BMS. Link is in the description.

[@jwbos85]

Hi Andy, 5 frogs! great video! I also had a the same JK BMS but switched to JBD due to the high idle power consumption (loss couple amps per week) when leaving the battery stored for a few weeks. What are your thoughts on the power consumption? Could you expand on that sometime? Thanks for everything!

[@andrew81632]

I'm not a fan of the side terminals. RV's are often designed around top terminals. The side terminals usually require a design change. Just my 2 cents depending on your RV build. I swapped an SOK 12v battery BMS for a JK inside the SOK case. If this was an option at the time it would have been far easier to build.

[@OffGridGarageAustralia]

Fair enough, thanks for your feedback and thoughts.

[@bramverhagen84]

Hey Andy next to lower voltage battery, can you something completely different and have a look at HV batteries? With our grid connected systems in Europe and more and more problems with the grid, that would be very useful. Thanks.

[@OffGridGarageAustralia]

Probably not, sorry. HV batteries are out of scope for everyone DIY. Far too dangerous and not allowed to handle. 48V systems are perfect and, in that home storage space, there is no need for HV batteries.

[@mandimandi2523]

HV is industrial. The prismatic cells are now so cheap to build your own powerful battery. If you think about the losses transforming 48 to 230V - well, then you have to buy the overpriced stuff from BYD and Co..... The ROI ratio is terrible ....

[@OffGridGarageAustralia]

@@mandimandi2523 Exactly, HV is industrial and not DIY. The ROI of a 48V system is far better than for a 96V system. Just alone the availability of 48V equipment makes it worth.
