why would anyone be pressing on them when fitted....you should always use antivibration rtv sealant to protect all parts in a dynamic system. also you should never use dissimilar metals, over time they will corode

Great video!

In model 3: Attaching the negative cable from the inverter at the opposite end of the busbar (nearest to battery 3 connection), would likely lead to slightly improved balance in the draw.

Nice to see high current cell tests. A little more context is welcome. Like room temperature, how this cell was charged and how long it has been resting. Keep on testing.

Love your video. How would you connect a solar panel with one MPPT to charge the batteries? I have two Lithium's connected in Parallel.

What size wire are you using?

I have three brand new EcoWorthy Batteries. They are 12.8v, however 1 is 280ah and I expanded with two identical 100ah versions. Have I screwed up by having A mixed bag as far as capacity is concerned? Jeff Your video was great, btw.

thanks for sharing!

I learned a lot thanks.

lol

Is there a way to connect 4wire Bluetooth?

The best video I've ever seen

It is not true that the Raspi has only USB-Ports. It has also an Ethernet-Port. Is it not possible to connect the inverter to the Raspi Ethernet port?

Nice video. I have 3 Gobel Power 48 volt 280 amp hour batteries with the 200 amp Pace BMS. I'm wondering if you have the LCD display setup available for sale now. It looks much nicer than using the PBMSTools software. Please let me know by replying here and what the cost might be. Thanks.

Are the 3D printed components printed from ABS / ASA or something along the lines of PETG or PLA. I would order but this would be going in a vehicle and i have had both PETG & PLA melt in the car before. Cheers

Subbed and liked. Glad YT algo did its job. I've been a solar DIY'er for about 5 years and found this to be a great visual for what I've been trying to explain to people for years. Thanks!!!

Is that voltage at the battery or at the load. Even with heavy wire you'll still get some drop. Obviously some cells are worse and that's the point of the video. I'd just bet the good battery was still closer to 3+ volts

I test cells professional and the cells could be.mixed old new all of the above

Thank you for the demonstration sir

Could uou tell the nsme of that device that reads how many Amps are pulled from each of the three batteries, with diffrrent connection.... , and how is it connected to each battery. Thanks. Nice video.

Is the app you are using on the ipad connected to the BMS in each battery via Bluetooth?

never seen such rubbish locktite

Very helpful information, thanks

Could you do 8 batteries on this in a 4S2P set up?

This is why you don't use 3 batteries. You don't need bus bars, and you get perfect balance, if the number of batteries are determined by geometric sequence. (1,2,4,8,16, etc.)

I want to learn this. But the way you move camera, it is hard to watch for more than 15 seconds without feel dizzy . Have to give up watching.

Excellent video, thanks

Price?

This is really a very nice video which proved that the bus bar solution is the best. what I don’t understand is: when using the bus bar solution why the second battery still has the lowest load although the second one is closer to the inverter than the third one.

I eliminate the buss bar alltogther, and place all in to one line, and using a copper switch to conected to a fuse, then conneteced to a main. it is all in a box this is what I did with even my agms, and I do the exact same set up with my solar array.. becasue the intersting thing, is the soilar arrays, are the exact same thing like ones batteries. .I jsut make sure that I am not over drawing what my lines can handle, I also tap my lines directly in to the charge controller from breaker to the battery bank. My charge controler has fuses in it aswell, they seem to be more touchy than the breakers. My newer system has a build in breaker and just needs a connect disconnet switch. they are starting to make these units idiot proof. I just make sure everything is tight.

I have a very similar setup using a Raspberry pi Venus but one thing you didn't mention, which I have learned the hard way is that the RPi gets its power from the inverter, which when it does a firmware update, drops the load during a reboot and the inverter then needs a total system reinstall. On the other hand, the Cerbo units are powered directly off the battery, so therefore are always powered up.

I really liked your video. Would you gain much if you connected the black (negative) cable to the stud going to the 3rd battery on the bus bar arrangement?

Make a video or test on it

Why you na try bolt all 3 batteries and inventor lead together in one bolt

Sorry but that is wrong one should come in from the other end to equal it out.

Hi, Can I connect this switch to the JK bms in the same way as on the SFK 200 amp BMS?

Sweet setup!

No one else had an issue with how close the pos and neg bus bars were to touching felt like one little bump or opps and sparks would be flying.

Thanks for a very educational video. I am trying to learn the effects and value of parallel versus series connections and this video did the job for parallel. Do you have a series connection study?

WOW never watched this video because of a non skip 11:12 min commercial.

Thanks so much for the very clear explanation. Question? Do you recommend using fuses with this set up?

Hi! have you ever had the problem of double hole shiny-coated connectors ruining the conductivity of the cells? (You cited them in your video). I know that is the vendor who welds the connections on the cells. This vendor measures the internal resistance only at the soldering points of the aluminum piece, but not on the surface that should contact the busbars. We have received good cells (REPT) but the connectors appear to be powder coated, like shiny metal paint that ruins the conductivity. It' s impossible in that point also measure the internal resistance of the cells. On the surface connecting with the busbars the conductivity is so lousy that the tester does not detect good resistance anywhere. This is dangerous and could lead to overheating problems and ruining the cells. The seller won't listen to reason and says that internal resistance has to be measured only at the soldering points -and not on the surface that should make connection with the busbar.(!) -. 🙁What do you think about? Thank U in advance.

What com leads would you use to link server batteries, multiplus and a raspberry pi together? Cheers.

If I bought a "Pallet" of anything and found out a mfer opened it and removed one item before selling it to me there would be a problem. If you're selling pallets, sell pallets.

So it is better to connect charger to the inverter than the busbar or the batteries themselves?

Excellent! Very informative and well presented. Thank you.

I have the same setup with everything on bus bars but with two batteries. I want to connect a shunt but I don't know exactly where to wire it because the bus bars are throwing me off. If someone would enlighten me I'd appreciate it.
