DIY Booster Battery for your Bluetti /Ecoflow Solar Generator

This list is for ordering all the components separately and populating the boards yourself.

For my AC200 I used 280ah batteries that are always charged by solar. These feed through a BMS and out to the charging port on the Bluetti to keep it constantly topped up. This avoids having to charge the 280ah batteries with a wall outlet. If the 'Big' batteries run low, the BMS will kick out and stop charging the Bluetti but it will then use its internal batteries. When solar is available again, the main batteries kick in and start charging the Bluetti again.

Jehu, you should make a video puting 2, 3, 4+ of these booster packs in parallel!

Great video. This is the best bang for the buck!!!

[ewok]

awesome content thanks jehu, from my calculations looks like just over 800 dollars to build the battery box if you buy the premade pcb from you and the 9 batteries, very cool and good value and not at all complicated compared to what most people would think

[chrisward]

The makita box is a great platform and they come in a few sizes . It would be great to get more pcb options for other batteries . Many of us can’t get these batteries. But can get others .

[thewilder-side]

Love your channel, frustrating that I can never get the batteries after you make video.

I like to cover my screws that come from exterior components, like the pcb, on the interior with hot glue. Just helps protect any wiring from damage

[jpjay]

awesome idea, thanks Jehu!!!
the PCB can still be used for all 9 balancers. (and 12V 2A charger)
just EXTEND the connectors inbetween with wires (tricky but doable) so half are surface mounted and half are"floating above the others" . easy

I just built a diy solar generator with the 12v version of these packs (sold out a while ago).
A DC power strip ( also for sale at jag35)
And an old computer tower.
I'm editing the vid right now.
I have over 9 hours of footage lol
It's 1kwh lifepo4
1200 w inverter
And supporters 500 Watts of solar
I also used the amp meter he sales for $50( works, but I can't figure out how to change the settings)
I haven't added up all the cost yet, but I know I'm under $500 total.
I also have 10 if these 16v bats that I'm getting ready to make into a 48v system for my bread truck.
I really like working with the pcb DC power strip he sales.

Now, just need to make it in a DeWalt Box!!!😁 Yes, I’m a DeWalt type of person!!!!😉 Thanks for all you do!

[sosgds]

This is amazing Bro! I love what you're doing!

[hackcn]

I think it's a good idea to put the charger outside the box.

[RandyRandersonthefamous]

This is very smart. Much easier to make a big battery box and avoid messing with all the circuitry for inverters and other junk.

[adrianhawkins]

Surely the charger is going to produce a lot of heat in the enclosed box?

[offgridwithpojectham]

One other item I am looking for would be the shunt. I didn't see that listed. Thanks for the help!

[ErnestoVillarreal]

Hey Garcia. You have inspired me in the 18650 recycle way, and I am building an EV with them! U have aprox 2600 of them, currently charging and testing capacity. Thanks!

[Michael-mgh-ncvy]

Awesome build and components I like the plug and play

[ericalvarez]

Price to build this now is more like $1, 000 or more now due to the PCB requirement to order at least 5 of the items and the charger and box are at least $120 for both if you get a good deal. Batteries you are already looking at almost 500 bucks, just for the convenience at this point I would rather save up a little more and buy an extra official battery for my Eco Flow Pro

[electrojessy]

You can make a step down converter 50v to 24v to power a cooler ( peltier ) ore a small cooler whit a small compressor that accept 12-24v its a modulair pack.

Good video

[MrSkipturner]

I made it. It’s fantastic! Great job making it easy!

[allglad]

Finally getting near functional with my build…put the box and internal electric stuff in and waiting for my slow charger and the 48v fast charger and I’m improving it.

…I have internal computer fans on the way as well as making it more difficult to get rain/moisture issues…. …plans are to drop the top wires, board, switch etc into the unit and adding a sliding hatch/door which could/should let it be in rain yet give easy access to the plugs, the coulometer/state of charge display, power switch etc have easy access also with them inside the unit they should be less prone to damage physically (including the water/moisture) …it’s kinda difficult to write as I’m still in the design/redesign phase as I do little things in and outside of it to also assist with the venting and water resistant features..probably going to add insulation/cushion to keep the batteries from moving and to make the wires anchored instead of dangling as well. I’ll possibly add a video.
