EB3A Battery Extender

I love my Bluetti EB3A but I always felt like it didn't have enough battery capacity. By making a simple plug adapter, I''m able to connect the EB3A to another battery or even my entire battery bank via the fuse block! So instead of the EB3A having 268wh it now has over 7,000wh!

I've gone a step further and actually directly connected extra battery by making y connect for xt60. So took the unit apart and connected the y connector with two batteries to the unit. It manages to charge both batteries with solar input which is awesome

[@OffGridBasement]

That is smart thinking! Thanks for the info and the comment.

[@CHRIS1887]

does it work with the 230v charging as well?

[@EvergreenAutoReview]

For real man, you gotta show us how you did it

[@Niekomojo]

How does it charge the external batteries as well as the internal batteries without an external charge controller

[@af1023]

Great video, I have almost the same set up, except I added a 12-24v 10A step-up DC-DC converter and get a bit more into my EB3A, EB70s and the Delta Pro 2. It really extends the use in an emergency. In addition, I wired a Shunt to the 12v battery to monitor the status, incoming and discharge wattage. This is great information, thanks for taking the time to share.

[@OffGridBasement]

Sounds like you have everything in order! Thanks for the comment.

[@Eric_M_R]

Thanks for the idea! Currently use my Eb3a to power a 12v cooler/fridge for camping and have to recharge off my Rav4 Prime twice a day.. it's a plug in hybrid so I charge the Eb3a off the 18 kWh battery but I have to keep the car on for an hour each time.. adding an extra battery would simplify things greatly!

[@OffGridBasement]

Glad I could help! Thanks for the comment.

Hi one thing I’ve learned after adding more batteries and all is that I should have just bought the bigger units to begin with. Much more clean and ready to go.

[@Shaken_AND_Stirred]

This is a great video and I thank you for it. I have the Bluettie EB3A as well and have recently been experiencing problems with it. I’ve hardly used it at all. This seems to be quite common. Mine “bricked” itself for no reason at all that I can determine. It kept showing “Short” on the screen with nothing plugged in. I kept connecting and disconnecting the power cord and pressing the DC/AC buttons to turn it on to no avail. I ended up just leaving it plugged in (like I always have) and now all of a sudden it is working with both AC and DC sockets working without the “Short” notification. In fact, I’m running an ICECO refrigerator/freezer now to test it and all seems to be working well. I can’t say that I can recommend this battery bank with these issues and Bluetti doesn’t seem to be helpful at all to anyone that has experienced this. Well, I got sidetracked there from your video. Hopefully mine will continue to work now and if it does, I’m quite interested in using your technique here to extend the battery life of my EB3A. Thank you again. Cheers, from Tomball, Texas

I'm glad you were able to get some info from the video. Bummer about your EB3A acting up. I've also heard customer support is sub-par. Thanks for the info and the comment.

I did that with my EB3A, including a 12 to 24-volt step-up transformer to maximize the input watts. Still, the setup is limited because 200 watts input can't keep up with 600 watts output.

[@michaelbeatty130]

I wish a low cost DC battery expansion system existed for these small solar generators. I figure it consists of three parts: 1. Charging the solar generator from an external battery (easy, done) 2. Switch input to solar if available, as most generators do not have two DC inputs. Automate if possible 3. Charge the external battery from the solar generator when excess solar is available. Automate if possible I haven't found anyone that's really attempted to build up a system like this. Maybe it's a fool's errand and the answer is to build a DIY system from components.

[@OffGridBasement]

Everything I've come across that can do anything like that is a few thousand dollars. Those abilities on a smaller unit would be great!

For anybody using your non fuseblock option outside of a demonstration, I recommend an in-line fuse off the battery + lead.

I use this method with a smaller powerbank that has nice DC inputs and outputs. Ideally we want a powerbank to have a true extender, charge and discharge both at the same time , instead of one flowing to another. An equilibrium and balance to minimize cycles.

a 24 volt battery would have brought you wattage closer to the max of 200 watts .On my channel i did an experiment with a Variable power supply. adjusting the power supply to almost 28 volts and the amps close to 8 i got 193 watts very close to the max input of 200 watts.

Interesting concept. Definitely more efficient than using a wall power supply. You could potentially also just hook straight up to your 24v system as well to utilize your solar to charge as well right? Just make up another pigtail to come off the 24v system.

[@OffGridBasement]

Thanks true! I should do a short on connecting to the 24v system to see what happens. I need to figure out a way to test how much more efficient it is. My guess is about 15 to 20%.

[@AdamDeLay07]

@@OffGridBasement You would guess you have use your AC power meter (like a KillAWatt) to measure grid wattage "consumed" then you would need to measure how many watts actually went into the power station on the DC side and divide those numbers. That would at least give you the efficiency of the AC-DC. Harder to say with the DC-DC because the actual converter is internal to the Bluetti.

[@arnoldsolof]

A 24 volt nominal PV has an open circuit voltage of about 45 volts, exceeding the EB3A 28 volt limit. It can be connected safely to a 24 volt battery.

I have a 12v to 24v step up convertor (buck convertor I think you call them) and if the EB3A is not-in silent charge mode it will charge at 150w from a 12v source I have. Without that convertor I just get 70w charging. Note that if you have the EB3A in silent charging mode it seems to cap the charging like this to 99w. I use a cheap second Power Station to extend the EB3A in this way.

Basicaly boon docking wirh the Blueetti. Thx for your input.

[@OffGridBasement]

The only thing I would worry about is if you have any other form of inverter input wired to the system as well. Having power pushed into the AC output of the camper inverter might be bad news even if it's not on. Other than that it should work just fine. Just remember it's only 600w. Hope this helps and thanks for the comment.

I will do that to enlarge the running time for my Campingfridge At the Moment my Coolbox is good for about 7 Hours on the EB3A , because she is running not all the time.

I’m really grateful for your videos I’m starting out new with these LIFEPO4 batteries and my EB3 A. your videos are very straightforward direct and to the point very helpful. do you think it would be OK to set up a 100 W panel outside (ground it of course) and run the wire inside fused and everything and then put my connectors on in the house and just hook that up to my EB3A and kinda use that as a charging station for the power station and maybe have some kind of a deal rigged up where I could charge a 50 amp hour mini battery on that same panel? Ok I think I made a mistake in my planning here,,,it would be better just to set up that solar panel or maybe two for the battery and just make your connectors and re-power the power station in thata way 👍😊

Why pay the double conversion penalty, instead of simply using a different inverter? This wastes a significant amount of the total capacity by charging, then discharging the EB3A’s battery. A small inverter is less than $100 and doesn’t have the conversion penalty involved with doing things this way.

[@cgryskie2820]

Great video - super helpful. What about this setup when camping for a week: Daytime - 200w solar charger plugged into eb3a solar charging port adding roughly 100-150 watts/hr. Simultaneously have a Haisito 20 amp battery charger plugged into an AC out port on eb3a to charge an external LiFePO4 battery (12v 50Ah for example) for full battery charge top off. In ideal sunny conditions both units could be completely topped off during the day. Night: use ring connectors from an external battery that end in a dc7909 plug and plug into solar input on eb3a. This allows you to use outlets/charging ports as needed overnight. Round numbers, the external battery will replenish eb3a at roughly 100w/hr with 12V or 200w/hr if using a boost converter to increase to 24v. If only running a fan and maybe charging a few phones/iPads, this could work indefinitely with sun by day. Any potential problems/issues with this?

New battery expansion for the EB3A is B80, 806 Wh For about 900.00$ canadian $$, but the problem is that the cable to make a battery bank is not ready to buy yet, i know it is a bummer , but at the same time i find the B80 expensive compare to just buy a regular battery.

[@mrabrasive51]

Can you use the same method to charge the battery through the eb3 and solar panels?

[@OffGridBasement]

Yes. Check out this video I did for more charging ideas. kzbin.info/www/bejne/pqHYm4OIgrhnj6M Thanks for the comment.

[@TecnoLoop85]

Good idea, but this usage is safe for the LiFePo battery or battery is constant under charging (short life) ?. Thanks I'm going to buy an Allpowers R600 with 400W of solar capacity

[@OffGridBasement]

I don't see any reason it would reduce the battery life. The charge rate is fine and the mppt inside of the Bluetti would stop charging when the unit is full. I would unplug the unit when not in use. I hope that answers your question. Thanks for the comment.

[@william38022]

Does the external battery just to help charge the power station or does it actually help the powerstation run longer

[@OffGridBasement]

Both. Once the power station is full it pulls from the external battery. Well, as long as it's not over a 100w draw. Anything over that and it pulls from the power station as well. Thanks for the comment.

Buck converter 12 to 24 v it make more watts charging might last shorter not sure

[@OffGridBasement]

Yes it will charge twice as fast, but you get a bit of wasted energy from the conversion. Thanks for the comment.

[@davidoldkitten2660]

if you hook it up to a 24 battery it will charge faster about 200 watt your EB3A can handle 28 volts

[@OffGridBasement]

That's true. I'm thinking about connecting it to my 24v system to see the results. Thanks for the info and comment.

I know you’ve tested quite a few batteries over the past few months. What 100ah one do you recommend that’s budget friendly. Thanks

[@OffGridBasement]

The Lifepo4 battery I like is the Redodo. Very simple battery with no bells or whistles. No heaters or cold temp protection. Just stores energy. It's a bit over $300. Here is a link if you want to check it out. amzn.to/3JqPfDQ I have the 50Ah version of the AmpereTime / LiTime battery and it's worked pretty well also. I've heard TimeUSB is also pretty good, but I've never worked with it.

[@nbc902]

Can I connect the BLUETTI 2AC to my BLUETTI EB3A

[@OffGridBasement]

If you have a cigarette lighter adapter to 7909 barrel plug it might work. I honestly don't know.. I would need to test to see, but I don't have a 2AC. I'm guessing the 2AC output is regulated @ 13+v, so that's what makes me think it might. Sorry I can't be more helpful.

[@genemitra]

I just tried using my EB3A while charging with 200w solar panel as I watched it from your other video. my solar panel produce more than 150w that time and I only connected a 10w clip fan on my EB3A. battery level is fluctuating to 99% and 100% when full charge every few minutes. the question is.. am I decreasing my EB3A battery life cycle with this activity of 99% to 100% up and down charging every few minutes? I want to know because I'd like to connect a large battery at night but im afraid if it'll just have the same issue. Thank you

[@OffGridBasement]

I don't believe this will have any issue with the cycle count of the EB3A. Small charges like what you are seeing don't have much effect on Lifepo4 cells. I believe something else in the unit will fail before the cells. Thanks for the comment.

[@genemitra]

@@OffGridBasement thank you

[@maxey83112]

How do you go about charging your battery bank without exceeding the input limits of the EB3A? Or do you disconnect the EB3A first then charge your bank?

[@OffGridBasement]

I don't believe it would bother the EB3A if the battery was also connected to a charger. I plan on making a video of ways to charge the battery that's connected to the EB3A. Thanks for the comment.

[@allenblackmer9583]

What size amperage with the boost converter? Could I get one rated for 15amps therefore not maxing it out possibly having the converter not run as hot? Or do these converters just go to their max regardless?

[@OffGridBasement]

Mine is a 10 amp boost converter. I believe the EB3A would limit the draw, so the bigger the converter the less heat. Thanks for the comment.

[@jime9305]

I'm curious about what happens when the bluetti battery bank and the external battery approach the same rated voltage, like at 80 or 90%...I wonder would the transfer continue or would the batteries balance out. I do basically the same thing except I do use the 12 to 24v boost converter and have never tried it with a stand alone battery. I guess it would go all the way to 100% since bluetti promotes the ability to charge with an automotive cigarette lighter adapter, thanks 🌞

[@OffGridBasement]

That is a good idea just to confirm that it works. Maybe have a battery @ 12.3v and see if it charges at the same rate. Thanks for the comment.

[@michaelbeatty130]

EB3A battery is 7S2P cylindrical cells, so the DC input is being passed through a MPPT charge controller to charge the battery. There's no approaching the same rated voltage but may see taper as it approaches the top. kzbin.info/www/bejne/bl6vqKxqZ9KVqdk

[@jime9305]

@@michaelbeatty130 So would it be correct to assume the internal battery is in the neighborhood of 24v ? 7 × 3.4v per cell would be 23.8v . I think I have seen that another teardown video of the eb3a. Thanks for the info

[@andyjack2368]

I have question for you ok do think a ups can run longer than like 1hour they very good but battery life sucks they like inverter you plug them to charge if power go you have few minutes of power I see people hack them make run much longer

[@OffGridBasement]

Yes. As long as you keep the battery voltage the same, you can wire up any size of battery. Most UPS are 24v 9ah. Basically 2 12v 9ah batteries connected in series. I don't know how fast the batteries will charge. That might be the downfall.

[@ChefAlexSocci]

Would it be possible to do this while charging the battery with solar through a charge controller? Ie solar panel into charge controller into battery terminals which are also connected directly to the power station. Thanks!

[@OffGridBasement]

You sure could. That setup wouldn't cause any problems.

[@DroneManMurphy]

@off_grid_basement - If you do what you describe does it increase the units ability to handle higher amps?

[@OffGridBasement]

No. It still can only do 600w of output from the inverter. Hope that helps. Thanks for the comment.

[@frankdumlao32]

Would this be the same as charging the Bluetti with a cigarette lighter in your vehicle? If not what is the cheapest battery I could use to do this set up? Thanks, great video!

[@OffGridBasement]

Yes. It is basically the same. I would just make sure to charge the Bluetti while the car is running. Thanks for the comment.

[@frankdumlao32]

Thank you for the quick reply…!

[@PieterBezuidenhout-v3h]

0:41 I leave my AC cable in all the time to recharge when power comes on. What happens with second battery? Must I only connect that once bluetti's battery is flat and then disconnect AC plug before I connect external battery? Must I then separately charge external battery again with it's own charger once it's flat. Might sound like stupid questions, but this is not my game

[@OffGridBasement]

Everything you said is correct. I could leave the secondary battery plugged in even if the bluetti is full, but then the secondary battery will fully deplete. Then you will need a separate charger for the secondary battery. I hope that answers your questions. Thanks for the comment.

[@PieterBezuidenhout-v3h]

Thanks for the reply, and I now have a seperate charger for external battery. If AC power goes off, my TV & Explora uses 130w but external battery (12v/105ah) only charge Bluetti at 30w which is 100w less than what it needs. It does extend it to 2h40min. which is only an extension of 40 min. Remember that I use Bluetti while AC is off and don't just charge it. Does the 30w input charge sounds correct?

You don’t really have that much extra capacity because it only chargers at 100 watts. If you limit consumption to 100 watts, then yes, you have the full capacity.

how do you charge the external battery pack using bluetti? is that something possible?

[@OffGridBasement]

I don't think you would be able to charge the 12v battery from a DC port on the Bluetti. You would need an external battery charger to plug into the AC. The best thing to do would be to have a solar panel connected during the day to charge the battery and the Bluetti at the same time. I'll try that out in another video. Thanks!

Huge waste of money. Actual useable Watts. About 240 ! Real life usage. What would you want to leave on for 7 hrs? A 500W heater. This Bluetti will not power it but for 1.75 hrs tops. What about a TV for 6hrs? Refrigerator? Hmmm? Then you must recharge it. Waste of money. Look at it this way. Nobody's talking about this low Watt available over the long haul for the nite or day. 240W ÷ 7 hrs = 34 W useable per hr before it's empty. Nobody's talking about this talking point.

This video is misleading and confusing. The eb3a is not expandable. Anytime you go in your dc input port you are charging your battery. Your proloning your usage. Its one battery charging another. There are models like the ac60, ac200l, ac200max, ac240, ac200p that are expandable. Basically, they use a cable called aviation to aviation cable and that goes pluged in an aviation port. Do your research

[@OffGridBasement]

All I'm demonstrating is the ability to keep your EB3A battery topped off by using another battery.
