Using Batteries To Extend Power Station Runtimes?! 48v LFP Server Rack 'Expansion Battery'!

[@1ENDUSER]

Finally someone puts up this idea into a video I've been wanting to see in a long time. Using server rack batteries as battery generator expansion pack. Thank you!

[@Jasonoid]

I hope the video is popular for people to see how easy it is :) It's a great solution!

[@1ENDUSER]

​@@Jasonoid- All to what you said. And also the value/capacity on money spent in buying one rather than the proprietary one to that brand. Just the syncing of the batteries to charging you lose on the brands. But you already showed this work around in another video so all is a go! Thanks.

[@michaeld4502]

​​@@Jasonoidreat 👍.... Could you do one more test on the Pecron.... Use 48v on one mppt and on the other use 24v to see how the reaction will be with different voltage.... While you are at it hookup the 12v on the 3rd port.... Seems to me that best way to use this full time is charge 48v on 600-1000watts on solar feeding the E2000lfp thus eliminating the brick.... Gives you 7040 watts for $1500 vs 8064 watts for $2800. Throw in a 100amp on small port and you get your missing 1k to be equal with add on stock setup.... Plus the DIY breaks the max limit of 8kw to infinity if you have Elon's money😊

What Sort Of Sorcery Is This ? 🤔

[@LordAshura]

Love the explanation. I made a 48 volt 50 AH setup with mppt controller that can accept 100v 20a of PV charge from the solar panels. I then hook up the Ecoflow Delta 2 max to it to get 500-1000 watts with xt60i cablces. This allows me to charge up my delta 2 max while not being limited a mere 60 VOC from Solar panels limit from its own mppt. I can then simply move the Ecoflow to wherever I need while continuing to store the solar power by having it sent to the 48 volt battery. This is way cheaper than trying to buy the spare battery unit.

[@Jasonoid]

Yep, that's a great way to charge your units and expand them!

[@selmopt]

hi, this is what im trying to do. Do you take the power from batteries CC to delta or dc load CC to delta? Also does your CC sync with delta batteries or battery pack? And finally what setting did you use on CC UV and OV? thanks

[@LordAshura]

@selmopt I found it simplest to take charge directly from the battery. The charge controller can have issues trying to communicate with the mppt controller on the ecoflow. The charge controller syncs with the battery. I use a victron mppt smart solar 100 volt 20 Amp for the 48 volt variant. I have 4 solar panels in series for about 88 volt voc and 10 amps for around 880 watts.

An excellent topic for those of us with a camper. Upon deciding whether to add an inverter to my slide-in truck camper - I opted to just modify a cabinet in order to slip in my modest EB70 power station. The power station is located above the 100 Ah LiFePO4 battery for the camper. Although I'm limited to a 100 watt recharge rate on the Bluetti, the EB70 is easily installed and removed from its cubby in seconds. The 100 Ah camper battery is kept charged via 175 watts of solar and a DC-DC charger that is connected to the alternator/truck battery.

[@Jasonoid]

Thats an excellent way to add an inverter / light / and USB charging to your rig. Simple and it works well!

[@myhificloud]

We definitely need EcoFlow to send you a set of EcoFlow Delta Pro's, the 240v voltage hub and corresponding accessories. Then ask Signature Solar if they will send a rack/stack of (6) 48v 100Ah 30.72kWh server rack batteries to perform heavy 120/240v charge/discharge loads using your EcoFlow Delta Pro's. ^A use case I believe many of us would like to see as an additional option to our existing permanent/mobile installs. Thanks so much for your very helpful, insightful and informative videos.

[@jacksherman7445]

Great video, as usual! I back up my Delta 2 with a 12v 100 ah Battleborn input through the internal MPPT inputs (XT60i) of the D2. Primarily I use it to extend the run time on my furnace in winter in the event of a grid failure. I have thought about using a 12 to 24v buck converter but I don’t know the efficiency loss. When camping I throw the 12v Battleborn into my DIY box and have lots more powering and charging options than a proprietary EB. However, if I didn’t have my two Delta 2s, I would consider the D2 Max and it’s EB…sometimes I think about getting the EB Max for the Delta 2, also using my own backup. My yard and house is shaded by 20 + mature oaks, an elm, an ash and a couple of Cherry trees. So, until winter, very little solar capabilities, so batteries are essential. I did install transfer switches for house back up. Your videos have “powered” a lot of my work, so thank you!

[@Jasonoid]

Thanks for sharing your setup! When solar is a struggle batteries might come in handy. I'd prefer the shade from mature trees any day! You can't beat the cooler temps in the summer that shade provides!

[@jacksherman7445]

@@Jasonoid I once read in terms of carbon offset, putting up solar panels provided a marginally greater benefit than did trees. I don’t know if I believe that but clearly the aesthetics of trees can’t be over rated. So, battery back up it is. BTW: I do have some solar panels from camping and two rigid panels I could use in an emergency…

[@salsero23]

Thanks great video again. You answered questions. We had communicated before, anyway I purchased the ECOFLOW Delta 2 Max, being delivered today. I was shopping around for expansion and decided in the EG4 lifepower4 48V. I will use this to expand the Delta 2 Max. I chose the Ecoflo because in addition to an excellent battery was the smart app. My main goal was to move some of my critical loads to the cheaper rate late at night here in Atlanta Georgia. The addition of the EG4 I can get a timer to only come on during the cheaper rate hours to recharge the EG4, small problem to fix. I discovered this video right on time. I will be double checking on cables.

[@buenobenji]

This seems like a really interesting solution to getting around the Anker 767 solar power input limitations. I’ve been struggling to find a combination of solar panels for my camper van roof that would max out the 1000w input. I would find it really interesting to see a test for this using a smaller and cheaper capacity 48v battery (50Ah?), a quality charge controller and enough solar panels to keep the 48v topped up while outputting close to 1000w to the Anker 767.

It's useful when trying to dual charge :) You'll have to let me know if it still works using the same source. The charging enhancer doesn't seem to like the 'shared ground' between the enhancer and the mppt when connected to the same battery.

[@jasonbroom7147]

Another excellent video. I appreciate how you explained that this does NOT add capacity to these power stations, it is simply charging them from another source, which can be done (with most of them) while they are in use. This effectively extends their run-time and I like how you articulated that distinction. I am using a variety of "2nd-life" batteries, like the 24v 9.6AH units you got from Battery Hookup. I like building stuff myself, even though there are definitely mistakes made along the way. I think the brand-specific options for truly adding capacity to these larger power stations are cool, but also insanely over-priced. I personally feel that if you need the kind of capacity they advertise with their add-on batteries, you're probably getting out of the "portable" space and you would be better served with a component-based system, at that point. Love your work!

[@Jasonoid]

Great comment Jason, I appreciate you watching the video and sharing your setup. I think there is a lot of value in finding used batteries and repurposing them :) They are usually CHEAP! haha

[@BeefNEggs057]

One thing wasn’t clear to me. So on the bluetti 200max was the pv mode on or was the car charge mode on for each battery type? Also is there a way to charge the 48v or 24 volt from the 12v DC 30 amp output? Boost converter would work, right? Be nice if power could go both ways especially when solar is in excess during the day. You could use an AC charger but avoiding the conversion losses is my goal. The boost converter has maybe 10% loss.

[@Jasonoid]

The Bluetti AC200MAX kinda selects the charging mode on its own. If the voltage is under 32v, it usually defaults to car charging mode and you can't change it. Charging from the 30 amp DC output could be possible if you had a 10 amp DC to DC charger.

[@vinjkdiesel3122]

Awesome vid, have been looking into building my own system or having a backup power system for quite some time & signature solar is, I feel, one of if not the best companies around. Building your own is very accomplishing & much cheaper. 🤙🏽🤙🏽🤙🏽

[@ebikecnx7239]

Jason I can't get the Bluetti D050S charge enhancer in my country. Will a step up boost MPPT controller wired up to the Bluetti AC200 Max 8mm port work? I could set the step up at the 58.8V output equal to a charge enhancer output. There's a step up 400W MPPT controller made by ELEJOY that is programmable that could be set to 58.8V max voltage. With 2x 200W solar panels in series with about 50Voc combined and 9A, that could work if it is stepped up to 58.8V and the amps would drop to about 8A or less, and of course with dc-dc converter losses along the way it should not exceed the D050S charger specs. The ELEJOY MPPT boost controller is only $35 approx, so much cheaper than the Bluetti D050S if only I can source that 7.9 or 8mm plug Bluetti uses!

I don't see why that wouldn't work. It might be worth trying since it's only $35

[@damonried1720]

I use solar generators for emergency blackouts (Texas Freeze 2021). Since the manufactures backup batteries are only two to three hundred dollars more than a base unit, I purchase multiple base units. If I had to bug out I can easily grab them and the portable solar panels, as opposed to cheaper, but more unwieldy, 24v batteries.

[@Jasonoid]

That's a great point. I have heard of a couple of viewers now doing the same thing. Why not have two fully functional units instead of a battery that is expensive and can't do much. Thanks for sharing your experience!

[@shelley131]

I think the way you did. After the Texas freeze I bought a 2nd Delta max instead of the extension battery. Also have the Honda generator I can use to charge them in case of inclement weather also, that way you just run the Honda generator for a couple of hours to charge them instead of running it all night long.

[@OneSubverter]

We are testing a more powerful replaceable portable power station, the replaceable battery weight is very light, but more capacity, if you are interested, you can follow us.

[@MindOverMetalTV]

​@@shelley131Ecoflow told me that the Delta 2 Max main unit can't be connected to another main unit, only to an expansion battery. Is that not true? Were you able to connect two main units together?

Could it be both batteries use a common ground?

[@TheQuietestOnesInTheRoom]

You led me here from a previous question on another video. Thank you! One thing i will say is with my Delta 2 test like your my xt60i cord feel warm. Its pushing 178 watts and the wire temp was about 80 to 90 degrees f. Well below what the 12awg can handle, but it was something i noticed. Maybe you did too?

[@Richi42]

5:02 interesting, I thought that the input should not exceed 15A (a battery can deliver much more) but it is in fact ecoflow which limits the input to 15A maximum. So we can also connect as many solar panels in parallel (10 for example) if we don't exceed 15A!? (nor exceed the max voltage 150V of course)

[@Jasonoid]

The power station limits the amperage. It only pulls the amount of amps it needs.

[@Richi42]

​@id ok thank you, is it the same for micro inverters like the enphase iq7 or iq8, can we connect a battery to the mpp of a micro inverter to produce at night for example? is the micro inverter limit itself the Ampers ?

[@Jasonoid]

@@Richi42 I have no experience with micro inverters so I can't say yes or no. From my understanding an micro inverter should be able to take in power from either a battery or a solar panel.

@@Jasonoid I also have the impression given your experience in the video I imagine that the mppt of a micro inverter is identical to those in the ecoflow or blueti that you tested. I think I'll try this myself. Thank you for your quick responses and for the video.

[@jaycarneygiants]

The expansion battery isn't talking to the power station so all it's really doing is charging it. Why not just use a stand-alone inverter connected to the expansion battery and charge via AC?

[@Jasonoid]

Either option is available, this was just a video to show a couple different options. I like to use DC to DC charging when possible since it's more efficient and why purchase a second inverter when the power station already has a good inverter?

[@whydontyouaskme]

Because inverters are inefficient, loud and produce a lot of heat. Mine is 90% efficient but it’s fab is occasionally loud and it heats up the space where my batteries and inverter sit. And I live in 100 degree weather so adding heat to the battle is ironic. My bluetti produces little heat, and I’m looking into the delta 2 I hope they also limit heat output

[@Moes_Prep_and_Tech]

I had an idea, since the server rack battery won't be used all the time you could do an anderson to battery clamp connection to slowly charge the battery back up if you were using ecoflow pro or dpu

[@Card_addiction]

Great information Jason, did you run a capacity check on the 24v battery from battery hookup? Thinking of buying a few for the same purpose.

[@rcguymike]

Would be nice to see round trip efficiency using the battery as input and then how to recharge, off DC from power station or AC? Might be a speed vs efficiency factor gained

Absolutely fascinating video thanks! Can I ask for some advise please? I have a 300Ah LiFePO4 leisure battery which charges automatically via the alternator and a Schaudt Booster WA 121545.

My question is, could I use a 12v to 24v DC/DC 480w (20A) converter regulator wired to my leisure battery to charge my Afiery P210 battery pack via the XT90 socket on the Afiery’s solar charging input side while we are driving?

[@damonried1720]

Informative video. I think you should look into why that Bluetti Charging Enhancer, rated at 500w max@8.2A, put out over 700w. Those things are designed to be connected directly to car batteries which can supply hundreds of amps.

[@Jasonoid]

I guess they didn't ever expect to have it connected to a 48v battery. It works fine with 12v and 24v batteries, it even works fine with 48v solar panels... weird stuff.

[@George_us]

I am not sure, if Jasonoid followed the startup procedure when using the EG4-LL, 1) connect the Bluetti Charging Enhancer to AC200MAX, 2) connect the 48V EG4-LL V2 battery to the Bluetti Charging Enhancer with its breaker & BMS switch both off, 3) close the EG4-LL breaker first, then turn the BMS switch on. This slowly brings up the EG4-LL 48V output voltage by placing & removing a current limiting resistor in-line. I plan to do the same with EG4-LL V1 batteries (using my Bluetti Charging Enhancer) and have my Victron MPPT charge the batteries . I have 900 watts of solar already going to the solar input of my AC200MAX. I have noticed that ( unfortunately) the AC200MAX doesn't always gives 100 % priority to its 900 watt solar input and tends to use the power coming through its AC charging port ( i.e., via the Charging Enhancer ).

Hey. Enjoyed the video. I was hoping you could do one on charging the Oukitel/ffpower p2001 from the 48v lifepower. I have a couple of the lifepower, and I am reluctant to plug them in directly since the P2001 says max 48v input. The Lifepower outputs 51.2. Would I need a DC to DC convert to ensure it is precisely 48v? Please provide a video on making cables and keeping the polarity for XT60 correct. The p2001 I bought (as you recommended) was the older version with Anderson connectors instead of XT60. Also, cables with ring terminals, MC4 connectors, Anderson, etc., to handle any situation. Perhaps affiliate links to materials or premade cables. Also. I found what looks to be the EPEVER MPPT Charge controller you showed, but all looked to handle a max of 36V. All of the 48V units were much more expensive.

[@Jasonoid]

The Oukitel / FFpower units are not compatible with these higher voltage 48v/51.2v batteries. The true voltage is even higher when at a full charge (usually around 56v to 57v). You may be able to find a DC to DC voltage reducer that will take the 48v output and drop it down to a lower usable voltage.

[@davidparker7156]

when you buy extended batteries that come with a power station are they used to charge the battery or are they used as a 2nd battery source? Also inn your example can you charge these batteries somehow? I am trying to understand the benefit of how you are using these as a 2nd battery source, seems like you would be better off to just use an inverter rather that using these to charge another system with it.

[@ainttakenanyshit]

THIS is NOT an "extender".... EVERY one of these "Capacity Extenders" videos have ONLY shown how to basically CHARGE the Solar Box at ~100 to 150 watts or so when home AC or solar is not available. To be actually called an "extender" a DC voltage of what the inverter operates requires, needs to be input to the DEDICATED "external battery jack" which then would power the rail or buss voltage of the inverter, "usually" around 48 volts or so.... MEASURE TO BE ABSOLUTELY CERTAIN OF THE INVERTER VOLTAGE REQUIREMENT....

[@davidvankainen6711]

So.... if the power station was under load, would pass-thru mode actually draw more power from the external battery to keep your stuff powered (at least with the non-cig DC inputs) in addition to the paltry re-charge wattages that you demonstrated? THAT would actually EXTEND the capacity in WHours vs just another means to recharge when you are "dark".

[@Jasonoid]

If the power station is charging at a faster rate than the load going out, then the external battery will keep the power station full until it's dead. The power station will start to deplete once the external battery is dead.

[@davidvankainen6711]

@Jasonoid exactly why I was concerned. All of those charge rates in the review were lower than the rated outputs of the generator so I thought.

Great video!! I have a Delta 2 Max and just bought the Ecoflow alternator charger.

thanks for the video, my take away diy expansion batteries are almost always cheaper per additional capacity added, but requires more work on yourself, while the expansion batteries are simple plug and play. shop around sometimes you can get great deals on diy solutions, but if you want a headache free solution, the expansion batteries are a simple solution.

Great video! ..... Question -- Using the process you've outlined in the video, can you connect the battery to, let's use the 48 volt EG4 battery, to one of those "All in one" charge controller / inverters to keep that battery fully charged in the day with using a max perimeter of solar panels of the inverter (meaning, you've got a lot of solar panels connected to the inverter and the inverter charges the battery)? I hope that question makes sense.... Thoughts?

[@Jasonoid]

[@hexd2g]

Great video! I have a AC200P and 24v LiFePO4 and I also didn't know you can simultaneous dual charge from the same battery. I will try that with my Bluetti DC Charging Enhancer.

I'm interested in the 48v EG4 for the future but not sure how that rack mount battery will do inside a trailer storage compartment. Do you have a coupon code for the EG4? Thanks for all your great videos and instruction!

12awg wire will be fine with both batteries. The AC200P has a limit of 12 amps and 12 awg wire is rated at 20 amps max. Only the voltage is changing with each battery and the amps are staying the same. No discount code right now for the EG4 batteries.

I just added the battery I ripped out of the broken Milin to the AC200P yesterday. I have a 180w panel into a separate MPPT Charging the Milin battery, and the XT90 from that battery plugged into the DC Charging Enhancer. I am not doing it to extend, I am doing it to try and smooth out the input. I vote for the DIY setup as I don't trust being tied into a proprietary battery. I think a 48v server rack, or series capable 12v lifepo4 is the way to go. They are modular and hence repairable, and easy to connect to anything. When the Milin died I couldn't repair it, I just had to disassemble it and take out the core which is just the batteries and a BMS.

I'm curious, what voltage is the Milin battery?

[@stevenblack122]

Similar point…if the 48 volt battery was hooked up thru xt60 connectors and with delta 2 max at full charge, …and the the delta 2 max went into pass thru mode, do you believe the 48 volt battery would work to flow thru and power recipient 12 volt draw appliances…until it exhausted and then delta 2 max would kicked in from its full battery?

Yes, that's how it would work. The 48v battery would keep the internal battery of the power station full until it dies, then it will use the internal battery.

Hi Jason, as always you continue to deliver great content in your videos that are very informative and helpful especially to the population that are not electronic engineers or solar geniuses like myself. Do you know if I can use the XT60i on my delta max that only has the regular XT60 plug? Also, would I get any benefit from using an XT60i in the future if I was to attempt to make a custom cable on my own? This video was perfect timing for me as I have been considering using a 12V battery to charge my Jackeries I use for my cpap/bipap machines. Would you ever consider doing a video showing step by step instructions on how to make cables with different connectors like battery clamps to xt60, mc4's , etc. Also would not mind if you could recommend which type of multimeters to buy. I don't know if I need to buy two like one with clamps that measure current or the one with probes and such. Love your work, thank you for sharing.

[@Jasonoid]

The Xt60i is compatible with all Delta power stations. You'll need to use it to get the most power. I'm not sure how the adapter is wired internally so it's best to purchase the MC4 to Xt60i adapter from EcoFlow to know it works properly.

[@Jasonoid]

Yes, the expansion battery will keep the power station full until the expansion battery dies. Once the expansion battery is dead, the power station will start dropping in battery percentage. This will be the case as long as DC charging input is higher than the load. If the load going out of the power station is bigger, the power station will drop in battery capacity.

Great video..Thank you for showing this. A lot of those power stations have internal battery voltages of up to 45V or higher. Since the input range on some of them is as low is 11V, does that mean they are using some sort of MPPT controller that boosts and as well as bucks the voltage? Most MPPT SCC require the PV voltage to be at least 2 volts higher than the battery voltage! But I guess these have the capability of boosting as well because so many people charge with their 13.4V autos?

I wonder if there is a way to hook up solar panels to both the external battery and the solar generator at the same time. During the day solar could power the inverter while charging the main solar generator and external battery, then at night switch to the external battery hooked up to the solar generator input and have this done by a timing switch or sensor that determines when the solar output is too low and then switches. I hope this makes sense. Good video. Thanks

[@Jasonoid]

It wouldn't be able to handle the voltage difference between the sources. You can only charge from one source at a time. One way around this would be to have your external battery always charging with solar and connected to your power station. Then you power station is always full / charging and the battery is being charged from solar.

Maybe you can buy a dedicated UPS / power filter to put on the output of the generator? That will cleanup the power from the generator before it goes into a power station. These power stations are pretty picky when it comes to charging input. They want 110v-120v and 60hz.

If you decide to expand your setup with 48v battery as in the video, I believe you can get EG4 Chargeverter and use your current generator. That way you will get clean charging into the 48v battery and then use the DC input to charge your Bluetti AC400. Good luck.

Additionally, what are your thoughts on wiring up an inverter to the 48V and charging via AC Input to increase? I wouldn’t want to use anything crazy maybe something like a 1500-2k watt inverter. Is there a better way to doing this that you might recommend?

[@Jasonoid]

It will charge at around 825 watts with a 48v battery server rack battery. This is the breakdown of that power: 55volts @ 15 amps = 825 watts (average) A 48v server rack battery has a peak voltage of 59v and when fully discharged it goes down to 48v. I don't think you would need an inverter to increase that speed. You could use a 2000w inverter to charge the AC200L at 1500 to 1800 watts, but you'll lose extra power through efficiency losses of going from DC power to AC power, back to DC power.

Excellent video! EG4 has some really great products. I am looking at this option for my AC200MAX. I already have 2 of the B230 batteries and 2 of the DC charging enhancers. I am wondering if the AC200MAX is experiencing a problem that was observed on the Pecron, ie, some kind of loop by using the same source on the two different inputs. I haven't checked with the server rack battery as i have yet to purchase one, but the charging enhancer definitely works by hooking a PV 350 panel to the AC charger input and 2 of the PV350 panels (in series) to the PV input. I suspect that having a common ground between the 2 inputs may be causing the problem. About twice a year, Signature Solar offers free shipping so keep an eye out if you want to order something from them.

[@johntate5284]

I think that by adding 15A or 20A blocking diode to each of the ground returns to the battery (15A will loose about 9 watts and 20A will loose about 12 watts), this would break the common ground of the battery or multiple batteries and allow Pecron and Bluetti to use both inputs from the same battery if the common ground is indeed the problem. I'm going to order some and try them out.
