REQUEST you provide your parts list or description... use your own part number or whatever, but I am unfamiliar with this equipment and trying to take notes is impossible to do correctly. C'mon, you can find a way to do this without giving up all your trade secrets!! Thanks

I collected a large number of USED lithium 18650 batteries from different brands. I want to build a new battery pack 8S10P (8 series by 10 parallel) for my e-bike. I have set up each battery bank with the voltage as close to each other as possible. 4.199 volts to 4.100 volts throughout 8 series. eg: bank01: 4.199volt to 4.190volt (10 batteries in parallel) bank02: 4.189volt to 4.179volt (10 batteries in parallel) .. bank08: 4.119volt to 4.100volt (10 batteries in parallel). The total voltage for the pack will be approximately < 33.6 volts. Because they are USED batteries. Therefore, they have different voltages and ampere. (Generally, 18650 batteries are 4.2 volts at max. Due to it being USED/OLD, therefore they dropped the voltage under 4.2v each. *_1) Do you think it is safe to mix the batteries with different voltages in PARALLEL, where the different voltages deviate in 1/1000?_* *_2) Do you know what the SAFE DEVIATED voltage is when connected in parallel?_* Please advise. Thanks

Shawn, Do you offer guidance on “tuning” the Multiplus II configuration? For example, if a person sends the download config file to you and you review and either modify or suggest mods.

Thanks Shawn. It’s running great

How many lithiumn batteries can you run in parallel? I have (2) 200 amp batteries and also just got from a friend (2) 100 amp lithium batteries, Can I add a total of 6 batteries all in parallel if I got 2 more batteries for a total of 800 amps. Thanks Andy

Excellent job. Love this layout

Question for you. Can you do parallel with a 3 wire instead of 4? I have 2 victron multiplus 2000va.

would it not be possible to use a usb cable, adapted (power & ground) to supply the 5 v for the LED's. In the UK its impossible to obtain the step down set up parts you describe. Great Video.

This is awesome. I was thinking of a 12v set up but size, weight bang for the buck a 24v sounds better.

Don’t they have an alarm or motion sensor on there?

Do you have any more info on how to make that custom 30A to 50A dogbone? Thanks

Grounding question. I’ve seen diagrams that have the Victron multiplus II grounded both to the lynx (lynx grounded to chassis with 4/0) and to the chassis directly using 4/0 cable. I’ve also seen ones where they ground 2 4/0 cables to the lynx and then have the lynx grounded to the chassis. How do you do it?

Some say the Victron controllers wont charge the battery till its over 5 volts above the battery. So if I'm getting 16 volts and 18 amps it still isn't charging? That's 288 watts. If this is the case what should I do to raise the voltage? You can charge a battery with 1 amp.

Nice job guys.

Still waiting for that in-depth and "lessons learned" video about the PowerKit... Can you explain further what you mean by tricking the alternator cables to be recognized as solar input? thx

For a small two panel (100w) lighting set up with two lithium 100amph batteries. Mppt controller and short run wiring, is series on both panels and battery’s best? Full sun no shading. Thanks!

If they did a all in one like this would be on point.

Before I installed the 2x120, I used an Aims 6000watt, 24v, 2x120. It didn’t have the cloud monitoring/control feature like Victron equipment. I went with the Multiplus II 2x120 as I wanted the capability to add shore/generator input to support when the Victron 2400 watt of inverter is not enough. I plan to repurpose my Aims equipment for a home solar battery/solar panel solution to power my laundry room, water heater and second fridge/freezer to save on power bill but also to help if we lose grid.

Can I run the same size lithium batteries from different manufacturers in series, parallel? I have 2, 12 V 100 amp Li-time batteries and would like to buy two more of the different brand( from a friend) and put them together in a 24 V 200 ah configuration. Is that safe?

Thinking to step up from 24v to 48v, installation have two of Victron 12v to 24v dc to dc chargers. What do you think about connecting them in series to end up with 48v of charging voltage ?

Great install. What type of screws do you use for the solar panel install? Thanks Don

Darn . How do you feel about getting “house” panels at a cheap price? Pros cons? Greatly appreciate your advice.

Do you sell gently used solar panels? I’m trying to budget build our set up running a victron multiplus 2 12v. 1-370 & 2-200 w panels . 2023 reflection 303RLS. Got extremely blessed to get at a realistic price!

great review! thank you, man! greetings from Argentina...

I’ve been watching your Videos lately and have a question. Why are people installing victron multiplus 2x120 when they don’t need 240 or they will install two for 5000 watts output what they could one quatro to get 5000 watts output. Rv’s don’t need split phase since nothing runs on 240 so why these spit phase units? Especially when victron makes single phase units. I’m thinking of upgrading my new camper it’s a 50 amp. What’s the advantage of these split phase units and do I have to use one for the fifty amp service breaker box?

Would the 280 fit in there?

You answered all my questions, thanks :)

You don’t show how to balance the batteries. Did I miss it?

The more I watch solar videos, the more I learn I don’t know a thing, lol. I totally get the series vs parallel and how they are different, mostly understanding how batteries work. My confusion is as follows. If I understand correctly, more Amps is what charges faster? If you run parallel, the amps stay the same, series, amps go up, help me understand. My main thing I want to do is as follows. I have an rv with a Go power solar starter kit. 190 watts, 10 gauge wire to the charge controller that is 30 amps. Series or parallel to add 2 more x 200 watt panels? Or, can you wire in series, voltage goes up, amps stay the same, you can put more solar, but is it really any gain? Sorry, but that stuff is so confusing, just when I think I understand, I learn that I don’t totally, lol Many thanks in advance

Which is better parallel or series? When you are charging thru a booster to a 48 volt bank

how do we get the special wire that was used to make the lights come on

Question for you… I have a Kawasaki side by side with a large audio system in it. The motor has a stator that charges the system. I have an AGM battery installed for the motor side of things and two lithiums for the audio. Both limitless LifePo4 30A. I have a victron isolator separating them. Think this will be a problem in the future?

When are you going to finish this install and explain in depth using 240v inverter?

Great video nice work, I have the exact same trailer, is that setup enough to run the air conditioner overnight? Thanks

Man you are a hack!!! The lynx distributor come in m8 as you have used but also in m10 which would not require drilling out. You have ruined that bus bar by both drilling it and then even worse filing it. The tinning prevent oxidation to help reduce any resistance which is critical in heavy current situations and then you have created yet another potential high resistance hotspot filing microscopic groves into a mating surface. Please please anybody reading this donot do what this guy is doing

What is ball park cost on something like this?

Very cool. We just picked up a 2007 Itasca Navion and I have intentions of doing something like this in it. This is going to sound crazy but I'm thinking about using a trailer hitch cargo carrier to build out a removable battery and inverter box that could be installed on several different rigs depending on the needs of the particular mission for that vehicle. There's just so little space in these tiny Class C's that it's hard to justify giving up any amount of storage for the electrical equipment. Well done on this installation, as always!

Hello, I have a question about the breaker that you installed after Victron Energy Lynx Power In. I’m just asking, does it make a different if batteries cables go to the top or bottom of this type of breaker?

Your numbers are all bs . If you talk about input and output ,you need to define your system . So 50 amps at what ? , your system runs at 12 v ,50 amps at 48v is 4x the energy. So at 48v your panels (your numbers) would be like 3600 w at 48v or 900at 12 …….

Such a horrendous bodge, with clumsy tooling, and an unfused short-circuit risk introduced across the busbars. Can’t see Victron rushing to follow your lead.

What did this entire project cost. I have the multiples 2 , 30 amp moot , just bought a 303 rls 50 amp. So we will be upgrading! Would love to get some outside information.

I have a 80 on the fire wall of my 64 impala I have no clue why .. I have nothing big that would need this .

More BEAR please

cheers, I wondered how to access that. Works amazing in my new 3rd adventure van.

Question. What about the VOC rating? Some say that is what counts.

Do you have the specs on the 200watt solar panels (size, dimensions, performance specs) you use on rooftop? I am endeavoring to optimize the rooftop solar on my bus conversion between the hatches. I currently have six, 250watt Trina polycrystaline panels on two superstrut rails in a train rail config (two rails length of bus between the hatches). I am considering putting superstrut rails across the roof (side-to-side) resting on the two rails in order to more efficiently mount panels to use the space up to about the edge of the roof.

I've been feeling stuck between going with 2x eg4 12v 400ah batteries or 3x SOK 280ah. I realized when watching one of your other videos that the EG4 is basically going to limit me to something like 1,440 watt (60a BMS) or 2,400-watt (100a BMS) draw before surpassing its max discharge rate and auto shutting down. Am I understanding that right? So my 3000 watt inverter is basically useless because it's limited by the EG4 batteries? The SOK can just discharge casually at 200a so with 3 I'll literally never be limited by the batteries discharge? Am I understanding all of this correctly? Reason I ask is, I will run an AC unit and a coffee roaster and routinely hit about 2,500 watts (from the inverter) for fairly short periods. Thanks!

Before you run the wire, wouldn’t it be easier to mark each roll and put a piece of tape on the end with positive one negative one positive two, negative 2?

Those bracket suck without a rivnut! Word !😊

Bet installer is having a recall now or gone from business.
