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.

Great review. I would say 4 1/2 frogs. It would be nice to see the box a bit more water tight if you wanted to use it with a electric boat motor. With the side cover that comes off for the compression bracket, water would come in. They did put the bms on too so that would help. Happy solstice to you down south! Sad day for us in the north!

Nice box, My only fear is the bluetooth signal strengh with full steel enclosure, maybe a little plastic windows for optional screen can solve this

There is a very lack of information about the own consumption of such devices. How quickly will such BMS batteries discharge if they are not constantly charged?

Looks really good, but really nothing to complain about. What if they would have put the BMS on the side, and had an window on the top so you could see the "valves" on top of the cells easily?

Five frogs for sure. Love the design as well. Manual not needed. Foam, is available in all good equipped offgrid garages worldwide, right?!! 😂😂😂😂😂❤❤❤❤❤ Thanks for testing.

5 out of 5 frogs - no doubt! Will be ordering a 24V version when I'm back from holliday :) Any idea if it's possible to buy without BMS? (I already have a 200A JK Inverter BMS that I'm using)

Moin Andy. Just ordered this kit. And had a nice conversation with Maio xin Tie. She even said that she had been in contact with you. I can't wait for everything to come in. And the real work begins.I am still discussing the MB30 or MB31 with EVE regarding the EU warehouse and the price difference. there is one in Germany. All in all, you are the inspiration and clear explainer of these systems. so I am now finally going to install such a system for my self. Don't worry I have a little experience with voltage and current. Thank you for all the great content.

So, is it possible to connect a NEEY active balancer to the Seplos V3 BMS so that the BMS can activate the balancer if and when it needs to automatically. As there is a set of pads to activate the Balancer it should be possible if the Seplos has an active balance output. Ideas?

Andy, 5 frogs is a bit too generous. You had to add foam out of your personal stock to make up manufacturing slack or missing sheets. Four Point Five Haggis's maximum.

Ich habe die fertig von EEL gekauft und seit 1/2 Jahr im Wohnwagen im Einsatz. Mich hatte das robuste Design und der günstigste Preis überzeugt die Batterie zu nehmen 😊 Klappt super 👍

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.

Well, it’s Saturday 22nd June in Ireland, Northern hemisphere, when we have just has our summer solstice. Now our days will be getting shorter and yours will be getting longer. So, enjoy the extra rays and keep up the great work👍

I used to let connected one of those cell meters on my scooter battery 7S 25.4V 60 Ah and after some charge/discharge cycles I had cell nr 1 and nr 2 with a significant lower voltage relative to the other 5 cells. Finally I realized that the meter to power the circuits uses the 2 first cells. Now I only connect the meter cable for some minutes to check the voltage and no more problems with the balance of the 7 series. Thanks for your excellent videos. PS: Just bought a JK BMS 150 Amp for my 15 kWh solar battery pack and I am very happy with it. All the best from Portugal.😬

Missing manual and foam.. 𝘔𝘮𝘮𝘢𝘢𝘺𝘣𝘦 half a frog. 🙂

I think I bent a 4mm steel plate while compressing my cells 😅😅 I can confirm no issues so far even the difference between the cells are minimized now 😊.

I wonder if could you try to parallel them both. Would be a fun experment

I'd be very interested in some 24v DIY battery builds, love the channel, Thanks!

Looked quite nice right up until I saw the Price ! Holy Macaroni !

Yes, 5 frogs. Very nice with all aspects.

thank you sir

Very tidy and sturdy design I'll give it 4/5 🐸

nice kit btw

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 ? ?

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.

Heya, yes a very good battery case but 🐸🐸🐸🐸🐸I don't know. as it is a 12V something like handles would be nice and not eveyone has those foamplates lighing around ( wel I don't ) and a manual would be nince for a lot of DIY'ers I think so I think I would go for 🐸🐸🐸🐸and as orange is the colour of the supporters of our soccer team that would give it 4,5 🐸 lol.

Great kit, thank you for this review! Glory to Ukraine!

Thank you for doing this 12v case. Nice to encourage good builds. Give it a 5 is the price is really good, Good as in the most affordable DIY case. I'll give it a 4 until I see the price.

I want to thank you for using simple and focused language. And entertaining.🎉😂❤

Hello! I live in France. I ordered 3 x 280a battery kits like your one. I told EEL ( Stella) that i want exactly the same batteries as yours with double nuts. Thanks a lot for your videos very helpfull 👍

4 stk. frøer årsag: stor box, kabler burde være formet til kassen, prisen er for høj.

I didn't see any handles? Hard to lift 30 kilos without handles?

QSO rocks - 16x MB31 - all over 331Ah. Top product.

Imagine his wife watching him doing the intro. LMAO.

I like the idea of building ones own battery bank for my Sail boat that has 4 x 215 12 volt AGM Battery's = 860 Amp hrs 50% usable power. if I had the same say 3 x lithium battery build using the EEL cases. = about 990 amp hrs of usable say 90% power this is major upgrade. My question does anyone know when you build the EEL cases how much does the finished build 12 volt say 315 amp battery cost to build in AUD? I there any savings from buying an off the shelf finished product ?

"Weather is amazing today, we had 80 amps" - One nerd to thousands

Is there a lot of bending stress on the balancing connector on pcb? This looks like a weak point. Is it through hole or surface mount?
