Can you please post a close up picture of the BMS wiring set up? For a rookie like me, that was a quick explanation but I feel that is the part I don't understand the most. Thank you very much for doing this. Also yes, I watched your other video about maybe not needing to add an additional BMS at all, but now I don't understand how to parralel the power ports. The life of being a rookie.... Thanks again for creating this video and all your other videos.
As a newbie , I only got SOME of what you did .... not enough to go buy and build , bcs the camera angles were not clear and the speed-up was useless . I think you’re very knowledgeable and talented , but not a good step-by-step teacher for me to learn . Sorry .
I have 2 of the EF 110 watt panels. Could I charge the the dyi box via the panels? I would use the adjustable voltage and amphrage box to get the most energy possible from panels into box.
The real cool thing would be if you could just buy the interface without the cells. Just a neat package that you can connect to your own cells with bms . AC-DC charger, MPPT, battery meter build in. Some 12v outlets usb fast charing, easy alternator charging ,optional inverter. Maybe bluetooth and an app to keep track of it all..This would make a lot of VAN/RV self builds much easier and more integrated.
Hey Jehu. The only thing I do not agree with is the male connector as the output on that case, that is short circuit potential for any close metal, as a rule I alway go for sockets as power delivery on high current applications. Nice build.
Brother I love your videos, However, can you onto the the Bluetti and make it a beast, that could run a house or a tiny home. A smart guy like you could do that brother. Or am I dreaming?
Since more than one person has asked if you purchase the large charger on Ali Express you want the charger with 0-48v / 0-10 Amp specs. There is a bunch of different specs but that is the one Jehu is using.
Couldn't I use the dyi batteries with my Ecoflow Delta 1300 sogen? If so, am I correct that I would only need the first cable external section (female/female)? And more importantly, then would the dyi box be able to be super charged from my 1300 somehow with 1300 getting recharged via AC? Without 1300 getting recharged at the same time? How much do those dyi kits weigh? Dimensions? Lastly, is there a similar kit with LifePo4 batteries that can function like the B300 and B230 units with the AC300 or AC200 Max? I'd love to watch side by side comparisons of the AC300, AC200 Max, Delta Pro, and Inergy newest one.
I have your scooter packs and 35amp 36v 10s4p BMS I got from amazon from the 1st video you posted on this aux pack. Can you put a link to the wiring diagram. Planning on doing at least 2 of these for my AC200 when I get it and also for my existing Bluetti 2400
Thank for the video! I noticed that you used the wrong XT60 with the battery, the female should be on the battery and the male (with pins) should for the load.
I hope Jehu responds to your post about this since I plan to build this and if there is a switch needing to be made I would love to know the answer to this before building it.
What about back flow from the Bluetti back to the Booster pack once the Bluetti is fully charged? I've had problems with back flow when I used a car battery to charge the Bluetti. It started off charging the Bluetti, but when Bluetti reached 100%, it backflowed to the car battery.
Thank you for doing this. I have the Bluetti 150 and bought 2 of the battery packs and will buy another next week. Do you have links that I can use for the components? And maybe wiring diagram ?
The bluetti looks like such a neat device. But it appears that you can't charge it using 12 V car sockets, is that correct? It would be a show stopper for me :(
That's a neat build. But somehow, I think that hacking the Bluetti to connect some external batteries directly to the internal batteries would be more fun. /s
I really want to build a couple of these. Here is a stupid question, can you charge these with solar? That is holding me back, I wouild want to charge these with solat when boondocking, how would you do that? Thanks
When charging the Bluetti 2000wP with solar, should there be any dual shutoff circuit breakers wired in and any inline fuses uses on each panel when charging to the max 700 watts in order to avoid overage amperage?
it was charging at 440 watts on the ac200. How do you calculate the output wattage formula? I know that w = v * i. But that doesn't seem to add up to output wattage. Trying to calculate if you could make it with a 6p or 8p. It can't be more than 700w on that solar input.
@@greengooseman I think I answered my own question....so the AC200 has a limit of 12ah which is what limited his charge wattage. It wasn't the battery pack, it was the device limiting it. Thanks for the reply, the info turned on the light bulb for me!
First off is it a safety precaution or protection of the electronics to leave the monitoring cable unplugged till you connect the blue and black wires from the BMS?
Not sure I understand all of it but the unit has a cigarette car charger cable. I'm guess it would take 18 hours of driving to recharge the unit. Could you attach a 500 watt inverter to the altenator battery and charge while driving? Would that be the same as plugging into a wall outlet? Tx
This is a great DIY project! I’m planning to make one once my AC200 arrives. Is there a simple way to keep these auxiliary battery packs from fully discharging when connected to the solar port, though?
@@josephnevin no not a good enough answer for me. the Anderson powerpole is just as available as the XT60. I always think of XT60 as a hobbiest connector vs Anderson Powerpole.
@@josephnevin also with XT60 you have to have a male and female connector pairs with Anderson Powerpole they are modular and inter-connectable so when you buy 50 pieces of Anderson Powerpole you end up with 25 pairs even if they are all black. Also the Anderson Powerpole has different colors. XT60 only has one color. With Anderson Powerpole they are modular. You can create your own custom connector with different conductors. XT60 can only support two conductors. Also the Anderson Powerpole can be disassembled, and the connector can be reused by simply removing the internal connector (keeping the plastic housing) soldering a new internal connector to wire and using that housing again.
You make a good and valid points. I totally agree with your views. In fact, I might consider using Anderson power pole connector instead of xt60 for my build.
GOOD JOB JEHU! I didnt buy this ac200 coz it only had 1.5ish kwh, but your solution makes me want to buy it. i wonder if you can use those electric car battery modules, or those used battery box modules that would be really awesome.
I'd like to make a few of these, but I wasn't clear about how you connected the BMS. A little slower would have been easier to follow. I have a Jackery Explorer 1000. Will this setup work for the Jackery?
Sir can you tell me how you charge your power wall of lithium ion battery pack what type of buck boost converter you use and what type of will voltage measuring sensors you use please tell me and if possible then please give me the link of that product link
jehugarcia well then,,,could you please make a video designing and explaining how to do this? thank you-PS- I like your content, and I really liked your episodes in Puerto Rico!
Fantastic video !! Question - when the booster pack is attached to the bluetti, and the bluetti is fully charged, will the booster pack continue to be drained? The energy from the booster pack shunted off as heat ( ? I'm learning .. out of my wheelhouse here). End result, don't leave the booster pack attached if not needed?
If I arranged these packs in 6P instead of 3P would I need to use heavier gauge? Would the same BMS be ok? I'm new to this & I'm wondering if the AC200 will pull more amps if there are more cells in parallel. Thanks
No the load remains the same in this particular application 12A, but if you planned on powering other things then yes each pack can put out around 20A x 6 = 120A which would require 2awg at least
Ok.... saw the links.... the BMS listed at 60amps is delivering in Nov.... Would a 35 Amp rated device work? I don’t know the max amperage of this solution
What option do we select for the power output when purchasing the large charger? They force you to make a selection various volts and amps. I thought this charger allowed a large range
If you are asking me what voltage to get, your probably better not getting th variable power supply, just order any 10s Charger they usually labeled as 42v
I like the idea of booster packs, but the problem for van dwellers is charging the booster and Bluetti separately. We don't always have access to AC plugs to charge high capacity battery packs like this. Is there a way to connect this booster pack so it charges with the solar generator at the same time? Then the Bluetti will truly have double the capacity without having to worry about somehow charging two items separately.
Yes plug into the Bluetti ac plugs, then charge your bluetti normally, it will take twice as long to charge your bluetti as it should since you now have twice the battery.
@@jehugarcia LOL of course that makes sense. Can the packs be charged using DC instead of AC? (yes, I'm a total novice, hence the solar generator vs home built option - but I'm willing to learn).
Nice and tidy solution. Only things I would do differently would be to use 10AWG, connect the BMS to the center battery pack and give it a female XT60 or XT90, same as found on an RC lipo battery so a 10S RC charger can also be used with it.
I ordered the bms from amazon with the your link. Delivery date is mid Oct to Nov, yipes. Do you have another alternative? I should have all other parts in the next week. Thanks for making this project available.
Yikes...I went ahead and ordered the batteries from Jehu but hadn't ordered all of the rest of the stuff yet. Thanks for letting us know and for asking this question...this will also be a challenge for me.
@@jehugarcia Hard to see the BMS connection on how you do it? At 5:04, you talked about it, but don't see it on the Diagram? Did you "T" splice into the wire?
So excited to try this! Thank you for sharing all the information. Some quick questions...if I attempt to recreate this using the links you provided, do I have to take apart the packs after purchasing, drain, recharge, and individually test all the batteries, then reinstall them the way you have done with some other videos before I do the assembly? Also, this might be a dumb question, but I am female and this is the first time I will have ever attempted building anything electrical and am rather limited on tools. I will purchase the soldering iron, but is there anything else maybe not mentioned in the video that might be necessary (like a Kill-a-watt meter, or any other measuring or testing device)? One last question, could this be used to charge my Jackery 500? I know it has more watts than the Jackery and I would have to switch out the cable going into the Jackery to an 8mm instead of the XT90/Bluetti cable combo , but does that mean that it could charge it several times?
Hi there Jehu, I have spent several hundred dollars on your website ordering batteries and would love to not destroy that money by building this incorrectly. Any chance of an update to the questions I asked above?
I don’t know what you plan on doing with these so I don’t know what you are going to need, none of the tools I use are hard to get, you can get everything on amazon . I don’t own your device so I can’t verify comparability.
Each individual pack is a 10s4p pack, so with 3 packs wired in parallel as shown, it's 10s12p as built. That's why he only uses a single 10s BMS, and balances the groups (12p) as one cell.
Tim D hello thank you for that information. I’m building my own portable power wall. I’m looking into seeing what packs I can buy. Soon. Everything I find sells out fast lol
Yes, by connecting all the thin wires between the packs each cell group is now in parallel between the packs. Parallel cells act like one cell, forming a single 10s battery which needs only one 10s BMS.
Hey Jehu why did you not use an XT90 on the expansion battery, then you would not require a XT60 to 90 converter. Please also look into XT90S, 'S' in spark free. Nice video 👍 Chud
Hey Jehu, If you left this boost pack hooked up to the Bluetti like you have it here in the video, and you plug in the Bluetti to charge it from the wall, would it also charge the boost packs at the same time through that port on the side?
He said he was using the solar panel port so I dont think plugging it into the wall to charge would put power out to solar panels. You would have to use a separate charger for the case battery.
Max voltage for this pack (36v nominal) would be 0-42v charger. As a 36v li-ion pack will run in the run in the 30v-42 range (low to high). The higher the amperage of the charger, the faster it will charge, so that can be whatever you prefer - usually cost more for higher amp chargers.
Unable to see your wiring. You started wiring some white connector. What was that? Then some of those wires were white and some blue. Why? Then you "explained" wiring the BMS but you did not show how you did it or the finished connection.
Anybody know if the AC Adapter from the AC200 would work for charging the booster pack? It’s about 400w but I can’t find the voltage or amperage listed anywhere.
Too bad. How about if I put it through a voltage regulator to drop it to 42? I ordered a spare AC adapter so it’d be great to use it other than when I’m in a hurry to charge the AC200. Thanks
here is an even easier way to boost your bluetti ua-cam.com/video/s0NQYcSHciU/v-deo.html
Thanks.
It woud be nice to purchase,rather than build it.
I had gotten one of the Bluetti AC200 on the indegogo for $1399.00 about 4 hours before the end of its fund raising.

thats cool now you can add on a bluetti charge enhaner with two more palas and we are ta;lking.
Well done. That's pretty slick. I might just have to do this. Not that I need to, but more of just wanting too!
Will that Battery extend the power of a Jackery Explorer 1000 also?
I have 2 of the EF 110 watt panels. Could I charge the the dyi box via the panels? I would use the adjustable voltage and amphrage box to get the most energy possible from panels into box.

Tim D hello thank you for that information. I’m building my own portable power wall. I’m looking into seeing what packs I can buy. Soon. Everything I find sells out fast lol
Can we use a single BMS for all N cases of batteries?
Yes, by connecting all the thin wires between the packs each cell group is now in parallel between the packs. Parallel cells act like one cell, forming a single 10s battery which needs only one 10s BMS.
Where c a n i purchase a battery pack?
Hey Jehu why did you not use an XT90 on the expansion battery, then you would not require a XT60 to 90 converter.
Please also look into XT90S, 'S' in spark free.
Nice video 👍
Chud
I couldn't found one that had mounting ears, do you know it they exist? in Xt90 version?
The same connector, on the battery pack, is used for load and charging, correct?
Hey Jehu,
If you left this boost pack hooked up to the Bluetti like you have it here in the video, and you plug in the Bluetti to charge it from the wall, would it also charge the boost packs at the same time through that port on the side?
He said he was using the solar panel port so I dont think plugging it into the wall to charge would put power out to solar panels. You would have to use a separate charger for the case battery.
Can u sell me one already build?
isnt it pretty bad to have a live maile connector?
Which charger? There are many. 0 to ??v
Max voltage for this pack (36v nominal) would be 0-42v charger. As a 36v li-ion pack will run in the run in the 30v-42 range (low to high). The higher the amperage of the charger, the faster it will charge, so that can be whatever you prefer - usually cost more for higher amp chargers.
I wish you shipped to Canada
Unable to see your wiring. You started wiring some white connector. What was that? Then some of those wires were white and some blue. Why? Then you "explained" wiring the BMS but you did not show how you did it or the finished connection.
but what about the heat from the batteries?
What heat?
I just thought there would be a little heat while you are charging at a higher rate. And being in an enclosed box maybe that might become a problem.
jehugarcia does the bms itself give off heat?
Anybody know if the AC Adapter from the AC200 would work for charging the booster pack? It’s about 400w but I can’t find the voltage or amperage listed anywhere.
It’s 58v so if It would be dangerous as it would eventually over charge the pack causing it to catch fire.
Too bad. How about if I put it through a voltage regulator to drop it to 42? I ordered a spare AC adapter so it’d be great to use it other than when I’m in a hurry to charge the AC200.
Thanks
what is the cost for parts for this power booster?
What about cooling?
