Great video. Many consumers new to solar energy do not know about this and will purchase expansion batteries for their units. I have a 48V battery that I use for emergencies to extend running times on my EcoFlow. I also have two, 12V mini lithium batteries. This are also great for me as I'm getting older and portability is the main reason for owning them. My wife can carry one should she ever need to. I may buy another pair of 12V mini that will provide me redundancies and also the ability to charge at higher rates by wiring them in series if I need a fast charge.
Cool video!!! I would much prefer to invest in a 24V or 48V battery for this type of charging. ECOFLOW MAX will accept up to 60V on the solar charge port.
It is also limited to 15amps (with a correctly wired XT60i) so a 24v battery will not reach the maximum 500watts. The battery voltage needs to be at least 33.4 volts so a 36v or 48v battery is sufficient to reach the maximum.
True, but I'm not investing in a system, I'm just extending run time for power outages. i have a regular old Delta 2 and use a Siekon 12v 100Ah to keep it topped off rather than give Ecoflow $450 for their proprietary extended battery.
Try using a step UP converter. 12V to 24V. Then try charging the delta pro through the solar charging port. The Delta pro may allow more watts input due to higher voltage. the steup converters dont cost much. $20 maybe
It is also limited to 15amps (with a correctly wired XT60i) so a 24v battery will not reach the maximum 500watts. The battery voltage needs to be at least 33.4 volts so a 36v or 48v battery or step up is sufficient to reach the maximum.
Did you try two XT60i cables attached to the same battery? Should double your input that way. The Delta 2 max is limited to 60volts and 15amps (with a correctly wired XT60i) so it is not possible for 12v to reach the maximum 500watts for an input. The battery voltage needs to be at least 33.4 volts so a 36v or 48v battery is sufficient to reach the maximum. Or use a DC:DC boost converter that can provide at least 500watts at 36v to 48v which are readily available.
I already reached the 15A limit with one cable, the only way to charge faster is increase the voltage using 24V and higher batteries. The charging speed is not perfect, but for camping it is acceptable since I don't need that much power all day. Having 4000Wh is not bad at all for minivan camping.
I have the delta 2000. I use my ebike battery. It's a 52v battery. The cable was about £10 and it will put about 1040wh back into the Eco-flow at 500w. Its a cheaper and faster solution
Oh, I forgot to put it in the video description, thank you for reminding me. I have just updated the video. Please check it out: th-cam.com/video/CBUX-V-lIoM/w-d-xo.html
The more voltage you use via external batteries the faster and more wattage your Ecoflow will charge. When i use external batteries i always connected them in a 24 volt configuration..If i really wanted to crank out the power into my solar generator i could use 4 batteries for a 48 volt configuration. I find using a 12 volt battery to charge my Solar Generator is just not fast enough for me.
The EcoFlow is probably a lot cheaper in the USA than UK so probably stuck with buying batteries, charge controller and inverter but with battery prices ever falling no great hurry (and our Labour govn is bringing back free solar installs for some households from June next year, so might wait on the details on that).
Yes but will not fully charge the battery. The 12V DC output of the Ecoflow is not high enough to fully charge the battery. That's why it is better to use a 24~48V dedicated charger for this purpose.
24 Volt 100ah Lithium Iron Phosphate Battery works allot faster and Helps top off My Delta 2 Pro and 2 Delta Pro 1,300's and My River 2 Pro at Night when My Fixed Solar Array isn't producing.
How bizarre, you listed what zip ties you used but not the most interesting part of the video, the load tester. Google Lens says it's the MasterHawk Electric Load Tester?

You are absolutely right, a 24V or 48V battery is more efficient. I am just experimenting with what is available.

@@vinnyandrocky The Delta 2 max has two inputs. Using both means 15a each.
@@Sylvan_dB Yes, you are right.

Thanks for the informative video. Where did you find the xt60i to ring terminal cable?

Can you make the ecoflow charge it?
Yes but will not fully charge the battery. The 12V DC output of the Ecoflow is not high enough to fully charge the battery. That's why it is better to use a 24~48V dedicated charger for this purpose.
If you have a MPPT controller you can use solar to charge it as well.
Good review.
Thank you
@@af1023 Glad you like it.
You can’t go wrong with an Ecoflow. I made the mistake of buying a Bluetti and have had nothing but problems.
It will be great if all the inputs and outputs are at the front.
Why 12V-200ah?
Better: 24V-100ah
24 Volt 100ah Lithium Iron Phosphate Battery works allot faster and Helps top off My Delta 2 Pro and 2 Delta Pro 1,300's and My River 2 Pro at Night when My Fixed Solar Array isn't producing.
That's an interesting solution, thanks for sharing!
@vinnyandrocky A Battery Bank o 4 of these wired with Marine Grade 10/3 from System to Kitchen in The Main Lodge here Supplements all Units
this is the exact solution for my boat but i am going to buy 2 of them and use a sine wave 2000 watt or 3000 watt inverter
Yes, I plan to have at least two in my van for long trips as well.
How bizarre, you listed what zip ties you used but not the most interesting part of the video, the load tester. Google Lens says it's the MasterHawk Electric Load Tester?
It's MakerHawk Electronic Load Tester. I added a link to my description. Thank you.
A cheap 12v to 24v step up DC to DC converter will give you way better results. I think I paid $35 or so on amazon for mine.
👍
