Hello ebazinam, Thank you for the kind comment. I'm glad you guys are making good use of this video. Happy holidays!!

Just FYI: I created this video to directly answer a viewers question, "how do you extend eb3a capacity?" He is new to the solar power generator world so he wanted to keep it simple without all the frills. I do not know how comfortable he is in tinkering with electronics, voltage, amps, soldering, solar charge controller, voltage up converters, ect, ect, ect. Therefore, I did not mention that in the video bc I did not want to confuse him. So, I kept the setup as simple as it can be. So just keep that in mind before commenting. Thank you for watching. Hope u guys enjoy.

Glad you like it! Im actually going to be making an updated video about this bc i bought some affordable equipment that will improve this method much more !!

I just did the same thing to My BLUETTI and have the 12v to 24v up converter. But depending on the output you want? They have different up converters with different wattage. Choose the one that works for your application. Mine will charge at 240 watts to keep up with pass through charging. But wanted to add there are several different styles of up converters.

@edwindeleon

Yeah, i just recently bought a 12v - 24v step up converter (going to make an updated video of it soon). It transfers energy faster to the eb3a at around 200watts. Best use for devices that consumes more than 100watts to off set the discharge rate. I ran a 150watt heater for about 5hrs.

I wired in a marine grade cigarette lighter style 12v outlet, with a cover, straight to my 20Ah LiFePO4 cell (which has tabs instead of posts). But I can charge it with solar that way, through my Bluetti, using a male to male cable sold for charging and jump-starting batteries car to car, which has a fuse inline. Or straight from the car. And I can extend the Bluetti with the battery cell using the car charging cable. Could probably jump my car, too, if I need it. One improvement I plan is to rewire in a three socket version of the power port which has a built-in volt meter and display. It isn't perfect, but the power management capabilities built into the EB3A (which sounds like a Star Wars droid, imo) make it all safe as an intermediate regulating device.

Thank you for this

I'm glad this video helped in some way or form. YES, you can do this with a different brand lifepo4 12v 100ah battery. As long as you are within the 12v-29v parameters of the bluetti eb3a solar charge input. As for the gauge of wire you're going to want to use the right thickness wire for the amount of current your system is going to use. So for this setup, the bluettie eb3a mppt charge controller clearly states 8.5amp draw. So your going to want to stick to 16guage (rated for 13amps) or lower (meaning bigger). You can go smaller but I would recomend to always go a little thicker just for safety measure. Btw hope that helps. Pls consider subscribing. It's free to do. But If u don't want its ok. No pressure. Thanks and have a great day!

Thanks I'm glad you enjoyed it. Pls consider subscribing. If not it's cool no worries. But to answer your question you most def can charge your eb3a with an external inverter!! It will be the fastest way possible to charge the eb3a at only around 30-50mins at 400- 430watts on turbo mode. Now you have to make sure that you get a pure sign wave inverter with the proper wattage for the eb3a charging draw. Also you will have to make sure you connect the inverter directly to the car battery . The cigarette lighter port will not handle the amp draw. And only charge it when your car is running. Also make sure your alternator can provide at least 40+ amp while running or it will kill your starter battery.

Also, there will be less parasitic drain from the regulation circuit. The 110v regulator circuitry drains about 5% per hour with out any load and the 12v socket drains less than 1% per hour with out load. My way around this is, I recently bought a separate 10amp MPPT charge controller, and I can now directly charge the external battery from the foldable 120watts solar panels. So I can charge the external battery in about 5hrs straight from the sun with minimal loss of efficiency!!!

So I always use these "smart" chargers that are built for the specific battery chemistry to provide another layer of safety. I understand that you can use any charger or even a power supply that can provide the correct voltage to charge these batteries but its good practice to use a smart charger that is specifically designed for the battery chemistry. I do a lot of RC hobbies and we typically use LiPo on our rig and these batteries do not have BMS.

If that makes sense. Also, not only I'm able to maximize the power transfer, I am also able to increase the capacity from 640Wh to 1.2KWh by running them in series. And thats not even including the 268wh from the eb3a internal battery. So technically I have 1.468KWh (1468 watt hour)!!!

Thank you for your comment. It really depends on your use case. If you are planing on powering your entire house then your going to need to get a bigger capacity system. This bluetti eb3a only has 268wh capacity. Although it has a 600watts pure sign wave inverter, Its intended more for camping or something with a very small draw. If you're planning on running a house I would recomend something with a minimum of 3kw system with a 2000watts inverter. This will only provide power for household items like a refrigerator, LED lights, fans, tv, ect ect. You will also need a solar panels minimum of 600watts. It can get very expensive using batteries and solar to power your home especially if you buy bluetti or another solar generator. A DYI will be cheaper. Alternatively, you can get a gas generator for cheaper route less complicated route.

Now If you are taking about charging it directly from lead acid battery with out the car then i would highly not recommend it. Technically, you can charge it with lead acid battery but it's not preferable bc lead acid battery drops voltage too quickly and you will not get a full charge on the eb3a.

Theres is always heat from any type of electronics. There will be always waste. It justy depends on how efficent the device you are using. I my self akaso bought a up converter on Amazon for around $25 . It also has heat. I tested its efficiency and it was about 95% efficent and that 5% goes to heat and waste. But i still use it bc it still efficent enough. Now if it was less then 50% efficent then i won't use is bc it will just be a waste. My point is you will NEVER find any type of electronics that is 100% efficient. Your PC, TV, smart phone, batteries, ect ect ALL produces some kind of heat. Even your eveyday car. Now do we stop using them just because Its not 100% efficent?

I"m trying to visualize how this is extending the capacity when I'm only seeing the battery just charging the eb3a. What happens when the eb3a is fully charged? Because I see it just like having a power bank for a phone. When the eb3a goes close to empty you have to connect the battery up again which is just like connecting it to the wall. And how many times can that battery recharge to 100 percent for the eb3a?

It's basically adding the external battery in series to the eb3a 268wh battery. The external battery is about 600wh then you add the eb3a 268wh which in combine is 868wh. I tested this with a 100w light build and ran it till both eb3a and external battery connected to the solar input charger and I got about 6hrs of run time (a little less bc of inverter inefficiency). Now i compared that to the eb3a with out ther external battery and i got about a little less than 2hrs run time. Which is about where it should new with the eb3a internal 268wh battery.

And when three eb3a is fully charged then it stops the flow of electricity from the external battery, which means eveything just stops where it is. Now there will be a little parasitic drain due to the charge controller inefficiency but it's very little. Imagine your phone when the battery is almost dead. You plug it in on a power bank (external battery) to extend its capacity and use it longer right? It's the same concept.

I'd like to run my 200 watt solar panel into an external mppt controller and out to external battery such as what you're using. I then would like to run a cable with a 7909 end from the battery or mppt (not sure which one would work) to the EB3a. My main complaint about the Bluetti EB3a is not being able to leave the solar connected when it's dark or light is too low. The input light blinks continuously and drains the internal battery. I thought if I wired it in the way as described above, the external battery would be used as a buffer of sort so I can get rid of that flashing input drain. Another idea I have is placing an inline timer switch and program it so the solar panels can only charge the EB3a during peak times. Anyone have any ideas or suggestions?

That actually sounds like it would work. Maybe try it out and test it. Using the external battery as a buffer, In theory it should work to keep eb3a frm draining whilst having solar connected during night time. It will continuously drain the external battery.

Of course, there are other power stations that are more powerful and have more capacity than the eb3a!! You have to realize that everyone has different power requirements! Thats the reason why companies build different sizes and capacities to cater to different people. Just like clothes and shoes, cars and SUVs; there are different sizes bc everyone has different requirements and needs. So, saying the eb3a is "lacking in power department" is flawed. Just bc your power requirements do not fit the eb3a does not mean the eb3a is lacking in power. For my needs the EB3A has more power than I need for a great price point of $200. And I am able to extend it to any capacity I choose if it needs be. Perfect for my use case!

This may be true with other 12v batteries but the battery im using is a LifePO4, which is much more advanced battery than lead acid or agm. The voltage on lifepo4 batteries stays above the required 12v and the voltage does not fall under 12v until it's about 0% state of charge, and that's when it cuts out. I tested this multiple times and i get exactly 640Ah while maintaining more than or equal to 12v.

@@edwindeleon Yes, that's right, but at a voltage of 12 - 13V, the charge power is less than 100W. And at 18V it reaches 200W, which allows you to quickly restore the charge.

@@viktor-ard-motorcycle I tried it out last night. When the external battery reaches 12.0v the eb3a charges at only 1 watt but it will continue all night long and drain the external battery to below 11 volts.

That is the achilles heel of the EB3A. It is not expandable like other power stations.

But it is expandable as I showed!! Just not the official way. Did you even watch the video? lol. I actually prefer this method as I can extend it to any capacity I want!! from 50wh to 50kwh!! With other powerstations with expandable batteries, you are stuck with the company's proprietary external batteries, and you are stuck with the capacity they provide you in their proprietary external batteries. And on top of that they cost sooo much $$$$. At least with this method I can choose whatever batteries I want, and they are way cheaper than the company's external batteries. You can get a 600wh lifepo4 battery for $150-200. And for bluetti external battery cost $1000+ and they are very limited with capacity size to choose frm.

Very very few systems are expandable (and by that I mean have a proprietary system for adding additional capacity). I've only seen ONE that had a straight up expansion port for ANY other battery to be used as an expansion (I think it had to be 24V to match the internal battery) so you're not plugging up your DC input port at a slow rate

It's a very inefficient way to charge.. why not just get a cheap charge controller to charge the battery directly

I wanted to use what i already had laying around at the house. I just recently bought a portable MPPT charge controller and im Going to be making an updated video with the charge controller and also a step up 12-24v converter. Pls stay tuned 👍

You will wear out the internal battery faster with this trick 😅

Not true!! I believe you have been misinformed. The internal battery will wear out about the same rate as if you were changing it with solar, car 12v cigarette lighter, or AC outlet! Where did you even hear that from? And do you have any hard evidence to back up your claim?

That's true but i will still only have roughly about 400wh capacity VS 640wh or MORE with the external battery. Im going to have to buy 3 eb3a to get the same amount of capacity of 1 external battery. Also, I would have to lug around all 3 eb3a whenever i go camping or hiking. Plus, I don't have any use for 2 additional eb3a. In my use case It would be a total waste of $$.
