Bluetti EB3A - taken apart and tested

[@nathanielvandoren]

I have an older lifepo4 energizer power station only has a 144wh battery and a 240 watt inverter and claims to do just 8amps out of the dc. I've found that I can power up a 5kw diesel heater when the battery is fully charged and not when less than about 60 percent. These smaller batteries might be able to hold a higher voltage if you test them fully charged. Thanks for these videos.

[@DavidMcLuckie]

That's an excellent test scenario. Thank you.

[@ChefDuane]

It would be nice if they could lengthen the screen time linger through the firmware update. I just bought one of these on an Amazon 4th of July sale (US) for $198US. Not bad. Nice to get a look at the guts of the unit.

[@thestujames]

I'm surprised you were unable to power the diesel heater. I have the EB3a and it works perfectly powering my 5kw diesel heater. Ran for 12 hours from full charge with 45% charge remaining.

[@DavidMcLuckie]

And that's why I want to test various portable heaters with the power stations. As the Jackery powered the same heater that the EcoFlow and Bluetti couldn't. State of charge may also play a factor in this.

[@DeltaCmndrElite]

@David McLuckie Your cable from the heater may be too small for the length, and you are suffering voltage drop/sag along that supply cable for the heater. Try shortening or using a larger gauge cable. My friend had this issue with his, and this I found was the problem

[@chriskey778]

I there do you think the 13 amp 3 pin socket could be rotated while you have the EB3A taken apart,as when the EB3A is on a work surface it's to close to the work surface to plug any of my camera chargers in. Factory moulded 13 amp plugs seem to be long in length.

[@fenceup07944931177]

So is there something that could sit between a power pack and a diesel heater, to give it a boost while the heater needs it's glow plug on?

[@wigenite]

13:52 any idea if that battery pack with BMS salvaged from broken unit will work without that extra com cable or whatever it is connected with a different MPPT controller?

[@DavidMcLuckie]

Unlikely. The connection with the rest of the system tells that particular BMS to turn the output on/off etc. But it would be fairly easy to just remove that board and solder on a seperate BMS.

[@jesseadams1986]

I have been waiting for this..

[@hardstein3585]

Thanks for your video. Since the purchase of the EB3A I´ve been using the unit in intensive mode 40 times. One charge a day in stardard mode from the wall socket and discharge along the day in different appliances (washing machine (cold programm), laptop, mobiles charging, home lightning,...) and I´ve noticed that it is lasting longer to charge from 0% to 100% from the first day. And I guess one day will be time to change the battery pack. Is it really difficult to build a battery pack for replacement with its BMS as seen in your video? Do we need to use the same BMS?

[@GroovyVideo2]

I had to fix one of these for a lady - solar input had a Cold solder that broke where connected to board - I made solder joint completely around connector - this solar input connector / board looks to be common between some brands and is not a sturdy enough in use - over all unit looks well made

[@mykolapyntia3191]

Hi! Please tell us about the AC input of the American version for 110V. Does the power supply support 220V voltage input?

[@DavidMcLuckie]

I don't have an American version.

[@istvan5674]

No, 110v for the AC plug input and 12v-28v for the DC plug input.

[@JD-zh6qe]

Nice Video! Do you have an idea where to locate the Bluetooth-Module? I would like to deactivate it.

[@jacobmar2797]

I'd love to know if you could put an xt60 splitter in parallel with the existing battery/bms to expand the capacity with a big cheap external battery.

[@DavidMcLuckie]

Should be technically possible. The only problem I can forsee is if you were to plug together a fully charged battery to a flat one. As they would try to even the voltage and you could get a large current flow between them.

[@loydhicks3413]

Your opinion is greatly appreciated an respected in which ever you recomend I just seen alot of people buying the maxspeedrod all in one diesel heater if you thunk I should purchase something else please advise me in the best fir alot of usage an cheapness 749.00 a month to live on dint allow a man any room for making mistakes on purchasing stuff

[@xxbambamxx7261]

I have the all in one, and it works great, but don't expect 5kw out of it, I'll say more like 3.5 at max, I've run mine in the basement, but when it's get really cold, it won't be enough for my needs... And if you try to adjust the fuel ratio to bring up the heat, you gain little, but burn alot more diesel.. I turn it up until I see some smoke, and then dial it back a little to get it to run as hot as possible, but not soot...

How to turn off BT? Is there BT antena or connector?

[@crywolfe210]

I just grabbed one of these on an Amazon return auction brand new in box! Hooked it up to my stealth camper setup in the back of my pickup truck.

[@crywolfe210]

Surprisingly, mine runs my diesel heater just fine!

[@DavidMcLuckie]

I'm going to do a whole video seeing which power stations can run different diesel heaters. Charge level might also play a role in whether they light or not. :)

[@mannyfragoza9652]

Hey David, is there a hack to keep the EB3As display to stay on longer than by the factory ? Its so annoying.

[@ralphwilmot6351]

The EB3A app is very basic, could do with more features like keeping the display illuminated etc. Hopefully they will add more features in the updates. Also WiFi.

[@mannyfragoza9652]

[@simonamjones]

Hi, would you please consider doing capacity checks on the portable power stations?

[@DavidMcLuckie]

It's something I've been thinking about. I need a test that I can set up and leave, but have the results waiting for me. I'm very open to suggestions. Something like a 200W load and some kind of time measuring device.

[@tramerr92]

I wonder if the space around the battery's is for air insulation. I've had mine in the winter with no heat and been scared they would die from the cold. Van life

[@DavidMcLuckie]

The cold doesn't kill them but depending on the BMS it'll either refuse to charge until they are warmer or it'll charge at a much slower rate until the batteries heat up.

[@jessechavez1]

What is the voltage on the cells alone

[@ianhaggart1438]

Hello. Would you be able to expand its capacity by extra external battery? Say 12v 24V. Cracking break down on stuff.. I do like taking things apart but it's normally to sort them.😁 stay safe 🏴󠁧󠁢󠁳󠁣󠁴󠁿

[@Dutchman1847]

By mistake I plugged in a big solar panel, exceeding 28vdc and the mppt regulator burned out. Any suggestions on repair or spare parts? Would greatly appreciate any help.

[@frostyfroze7352]

Watts ÷ volts = amps so power lift will lower the voltage to provide the current needed for non voltage sensitive items

[@oojimmyflip]

I reckon that socket on the side of the battery management board is a charging balance socket.

[@BEYTEK]

do you think i shoudl run a diesel heater in my RX7 instead of heater matrix? lol

[@mannyfragoza9652]

I have the EB3A and it does what its suppose to do. But If they made the EB3A with lets say 700 watts it would be little more useful or one that can take a supplemental battery like the Ecoflow River. That is a great idea for smaller capacity solar generators such as the EB3A.

[@DavidMcLuckie]

Bigger inverters get my vote. Add on batteries would be good as well, but of course that would increase the price.

You can add on battery to the EB3A through the solar charging port, the 8mm jack. I recharge mine regularly this way from larger batteries.

Whst should I buy in size do you recommend there fairly cheap in the states

[@DavidMcLuckie]

I'd put as many solar panels on as you can fit. How often does your van move? I ask this as I'd also mount the panels on the adjustable bases so they can be angled up to point at the sun.

[@frostyfroze7352]

Nice to see that has earth pass through, North America with US style plug don’t have that, just a plastic hole we’re the ground pin supposed to be. The yellow plugs inside are xt60 connector, common in rc hobby world

[@pwelsheimer]

Great video! I purchased one of these on Prime Days (Amazon) and would love to use this for portable ham radio ops, but the limit to 10 amps DC also would limit my TX power. While you were in there did you see anywhere to tap off to get 12v but have a greater than 10 amp service? I'd rather not have to drag my 30 amp power supply to run the Yaesu as that wouldn't be very portable. 😉

[@DavidMcLuckie]

You could try tapping of the batteries before they go into the inverter. But this would still be at battery voltage and would need to be stepped down to your 12V

[@rednecktek2873]

I'm surprised it's 24v inside there. With those cells if they had run the batteries in 2p4s and everything based off 12v DC, I bet the diesel heater test would have worked better.

[@dm1126]

I have a sort of knock off unit which beeps and beeps every time there is a high power demand like my fridge turning on... It's ok with the diesel heater. I opened up the unit but as I am a civil engineer not an electrical one. I don't know which part to disable or what it looks like any assistance would be greatly appreciated Cheers Dave

Thinking of getting a power bank to mainly run the diesel heater 5kw , would the jackery 240w (small one )work just fine ,or is it worth going one more level up in the jackery range ?

The bigger you go the longer you can run for. Or the longer you can go before needing to recharge the Jackery.

is it possible to more batteries inside eb3a ? even if i dont close it its ok

You could put another set of batteries in parallel as long as it is the same voltage and has its own BMS.

[@istvan5674]

You have to use the DC barrel plug and regulate the voltage and amperage to what it indicates for the MPPT charge regulator in the unit. I've seen DIY lithium ion add on battery packs, I'd prefer a LiFePo4 instead of a Li-on battery pack for a back-up. For the solar then you have to have a MPPT solar charge regulator to run your solar to the battery pack to keep the whole thing charged.

Hi David. Firstly; I have a apologies to you about ; I didn’t believe 600w power station has not handle a diesel heather. I was very confused it.

Please don’t buy Eb3a . Don’t buy for diesel heather. Buy different power station , like jackery or different brand one. Thank you for video and reviews again.
