[@raymccormick545]

Great information for those of us that dabble in DIY efforts. Thank you

[@kuhrd]

One thing that may be beneficial if the specific power station can use a much higher input voltage is finding a boost converter with an output voltage just a bit under (5-10% or so) the max recommended solar input voltage or get one with adjustable output voltage range and just make sure you are not going over the max wattage rating of the boost converter or battery you are connecting to. This will allow higher input wattages for the power stations that support faster solar charging. Many of the portable power stations are limited in charging wattage due to the size of the solar charge controller they use so if they support a higher voltage that can sometimes yield a higher input rate till you hit the max rate of the internal solar charge controller. One other thing to mention about those boost converters is that they tend to want forced air cooling if you drive them much over their rating for any length of time.

Nice idea. I’ve been planning to get a 24v-12v stepdown converter on a 100w solar panel output to run my fridge by the pool this summer. Maybe you could do a video running things off a solar panel with a converter instead of a battery. I know I’d be interested.

[@googletitsfost]

An mppt solar charge controller is basically a smart DC to DC converter which will do exactly what you are asking. Or go for a pwm controller if you want cheaper (£10 or so) but at a risk of less efficiency. The cheap pwm ones typically don't even need a battery.

I have an EB3A that i connect via cig lighter cable to 2 100ah AGM in parallel. They are charged via 300w of solar. Dont have a heavy load on the EB3A yet, but I'm optimistic. My pellet stove draws about 150w, and the AGMs will run it all night.

[@randyfontaine1301]

This is great info. Do you think it would work with the Oupes 2400w Power station you reviewed a short while ago?

[@bru_haha]

Good idea for a low price expansion. Another downside is the low efficiency and the extra cycles put onto the main battery. These small power stations take 15-20% more than rated capacity to charge, even over DC (512Wh capacity takes over 620Wh of input to charge), plus the 12 to 24V boost converter loss of 5-10%. Then you lose another 15-20% from the typical inefficiency of the power station when using the inverter/regulated DC. So if you do the math for something like the Ecoflow River 2 Max with 512Wh and a 1280Wh external battery, you are getting ~415Wh (original output capacity) plus just ~785Wh AC output capacity from dumping the 1280Wh into the unit and taking it out. The loss is much greater than compared to if you just hooked up an inverter to the external battery and used it that way, plus you effectively put 2 extra cycles of wear on the internal battery of the power station by dumping in the 1280Wh.

Well any expansion battery is going to have that issue. Always buy the largest battery you can get away with.

Inverters aren't 100% efficient either. And you're now going from 12VDC to 120VAC and back to 12VDC. I don't see how that is better than 12 to 24 to 12.

I don't think most power stations would charge the expansion battery. It would require connecting either a 120 volt charger or a 12 volt charge controller. 12 volt charge controller assumes the power station has 12 volt output.

A DIY to make a similar expansion battery to a Ecoflow, Bluette or Pecron, would be nice, all in one box that has similar capabilities to theirs and you can use it for multiple solar generators to recharge them, and recharge the battery somehow using the solar generator in some way.

The advantage of the more expensive add on units the much higher watt throughput. If you don't need the max wattage for extended periods of time I could see this method working out okay. If you need to run high drain loads , it won't help much. If you run any kind of heating load very long it will show up quickly. If all you are running is led lighting and small electronic rechargers, this will work well.

You certainly can. I have this setup. You can bypass the booster, no problem. Plus you can always combine two 12V 50ah & get 24 (actually bit more, like 25.6 Volts) should you need the extra boost. I rather have two batteries, cheaper too for some reason, at 50ah than 100ah with a booster. Food for thought.

While I was experimenting with my Ecoflow power stations and a Power Queen 100Ah battery, I built 2 10AWG cables from the battery to the Ecoflow unit. One cable had the regular yellow XT60 female connector, the second cable uses a XT60i orange female connector.

[@reese9276]

Your connection was directly from that battery to the River 2 Pro without the transformer? So this acts like "Pass Through" charging. As long as the output from the main battery doesn't exceed the incoming power, the main battery "remains" charged except for inverter loss? (YES...l'm a "Newbie")

I just subbed so I can remember to check some of your stuff out when I get a chance. There's another channel I've come across (Jasonoid) that did something very similar, but it seemed more complicated and I wanted to show something that did basically the same thing but less complicated. And pretty much within minutes of posting this video, it occurred to me (after someone raised a question about it) that there's an even easier way to do this using a 12V car socket - though it undoubtedly will produce a bit lower watt input in some power stations. I might need to do a part 2. :-/

The first thing I thought of that you didn't mention was that if the power bank supports charging from 11v up why even use the converter? Just connect the battery as is. I've done that with my ups and it works fine. In fact the ups even charges the external battery when connected to the mains.

[@archstone4622]

Agreed. Just connect the battery to the DC input and the time remaining jumps up due to the extra battery. That way you eliminate any power loss from the step- up device.

[@MichaelAngeloTech]

The intelligent power stations will limit the 12V input because they have to assume the voltage is coming from a cigarette adapter like in your vehicle which are limited to 10amps. This would charge the power station very slowly at around 120 watts. If the voltage is “boosted” to 24volts or any higher voltage battery is used, the power station will sense the input and assume it is something like a solar panel and increase the allowed input current so you will charge the station much more quickly.

The main advantage of the expansion battery on units that support them is that they are also charged off the same internal charger and solar panels. This idea is fine if you only need power to flow in 1 direction, otherwise you will need some method of charging the external battery either with seperate solar panels and an MPPT charge controller or some other external battery charger. I suppose you could connect a wall powered lifepo4 battery charger into the power station to keep the external battery charged up using the a/c output of the power station, or some sort of dc-dc charger that is under 10a running out of the cigarette lighter adapter on the power station. I might have to play with that and see what happens.

Just curious, but why wouldn't you just connect the 12v LiFePO4 directly to the XT-60i (for example) solar input on the Ecoflow (12.8v typical on these are well within the 11-60V)? Other than getting better charging watts from the higher voltage at 24V (or even 36-60V would be better), it should still charge quite well at around the 180W you are getting out of that boost converter (make SURE you use the ORANGE colored solar input XT-60i so it doesn't clamp you at the "car charger" 7A max). It would be much better to simply put 2 or 3 of these batteries in series to charge and get the full 500W (for the Ecoflow Delta 2) at any voltage >33v (other chargers may have a higher MPPT max current that could benefit more from 48v). Honestly, these DC boost converters tend to waste a lot of switching power in heat and even putting just two batteries in series (to operate at 24V) would be dramatically more efficient and faster on charging current and avoid one more complication. ?

[@ursodermatt8809]

because it only put half the energy into the power station. they are limited by amps, so you get twice the energy if you double the voltage.

[@jeffmcclain]

@@ursodermatt8809Understood, but 12v @ the 15A of XT-60i is 180W, which is much more than the 125-150W from the boost converter (plus you lose soo much in heat doing the boost). And just putting two 12v batteries in series (or better 3 or a 48v server rack battery) would easily be far more current than those DC-DC boost and much much more efficient. That was all I simply don't understand why folks are spending money on very limited and inefficient converters when they could do it simpler.

[@p.b.7861]

You are exactly correct. Much easier and cheaper do away with Just a cable with XT-60i to 12v-100Ah lithium lifepo4 battery is all you need ! No 12-24 booster needed at all.

Your LifePO4 battery should have a floating voltage of 14.4V and powerstations usually require an input voltage of between 12V and 30V, so the DC-DC regulator should be something like this '8-40V to 13.8V 25A', as it slightly reduces the LifePO4 battery voltage to match the input voltage range of your powerstation. The DC-DC regulator you are using does not seem suitable.

[@whatmattersmost6725]

These are a DC-AC-DC inverter that takes a DC power and chops it up and then back to DC out. I expect on the power station is this device does not make a pure sine wave but modified sign wave that can cause issues.

[@anthonyglaser929]

so if all of those power stations had a minimum of 12 volts do you really need the step up converter to 24 volts? And if you have 2 of those 12.8 volt batteries and you run them in series that would work as well right? or one 24 volt battery would work just as well?

[@johnturner9561]

Really enjoyed your work, I came across your video the bluetti ac180 a short time ago on this system and purchased one. A great mid size unit,and after watching your video on using a 100ah battery to increase capacity I do have a question. Should I use a capacitor to perchance the ac180 before plugging in the cable to prevent the end rush voltage or will it be safe.

[@smaxinfo]

Конденсаторы используются в преобразователях dc/dc. Они там уже есть в схеме. Мне известно что в bluetti в схемах внутри есть интеграция "медленный старт", по этому, вам ничего дополнительно придумывать не надо.

[@TOMVUTHEPIMP]

No.

[@analynquitolim9285]

I am planning to do this to my ac200p but one question what is the best charger for the battery

[@Electronzap]

Yeah, should definitely use the solar power station as a starting point, then add capacity with battery banks and keep adding your options from there.

[@blackimaje]

could you use the 12-24 volt 20 amp 480 watt version for the delta ? wouldn't that drastically increase your input wattage for improved charging time? not sure why you would only use a 3 amp charger

[@djr13099]

I have a 12v lithium ion phosphate battery and just with wiring and no step up, I can get 78 watts into my powerstation which has a 24v battery system inside. Just an fyi if going camping and trying to avoid all the extra pieces like a step up converter.

[@Carlos-jh5tb]

Shouldn’t you add a relay and switch and a fuse? Does the dc/dc consume even while not plugged into the Blueetti?

[@CraigslistResponse-zr9bd]

A few comments say hook up 2 batteries in series and on the ecoflow should get 360 watts, right? What about 3 batteries in series for 36v and get full 500w into delta 2?

[@JustaCuriousity]

Hi thanks for the information, i really need the cheaper expansion option. I wonder if i can use 100ah 48v lifepo4 for delta pro expansion?

[@ReeWrayOutdoors]

Just looking at the Delta Pro Solar (DC) input specs, it shows 11-150V @ 15A. So I'd think as long as you put a 15A or 20A fuse on the POS lead between the 48V battery and the Delta Pro connection, it should work.

[@surfx4804]

I get 160w into my EB3A using this method, and the I used source is a cheap power station. I did have to put the EB3A in standard charge mode and the noise is the fan that comes on.

[@ReeWrayOutdoors]

Nice! It actuality never occurred to me to check the charge mode on the EB3A! Good catch!

[@bdmenne]

QUESTION: How would I get 200 watts or more through same system, but for a medium Station like River 2 Pro (NO expansion battery for it)? Would a 200ah Battery deliver this? On the solar max wattage for it is 220 so. It can also handle 800 AC charging. Thanks

[@anderspettersson4171]

I came across this while thinking of a UPS for my home server and finding out how expensive things from APC are while comparing capacity while a portable power station can double as a camping powerbank, a APC does not suit for that. Any idea of how to also combine the charging part of the expansion battery?

[@gde-to-kogda-to6130]

Can i use 24 v battery directly on my power station, will be any harm ? thanks

[@themachine8427]

Can you not connect the battery to the expansion slot on the power station?

[@Whillerz25]

Nice... I have a question, how would you prevent or monitor the discharge of the external battery? Is it safe to let it fully discharge?

[@TOMVUTHEPIMP]

Buy one of the batteries that have Bluetooth.

[@nunyabusinessfriend]

Is there a reason not to use a larger capacity version of the converter in this video to help with a faster charge? Thanks for this content!

[@ReeWrayOutdoors]

Not as long as the step up voltage does not exceed the input max on your power station's DC input spec.

[@jeffmcclain]

...you mean like just directly connecting the LiFePO4 battery to the solar inputs? Better, put 4 of the batteries in 48V config and direct connect.

[@smarties2k]

Can I use 12V TO 24V 15a 360W DC-DC Step Up DC Converter on Ecoflow River 2 Pro?

[@sgtusmcarch]

can I charge the battery with an MPPT controller using solar, while the power station is hooked up to it?

[@pierrebonin5384]

😅that's a great idea. The fact is that I know nothing about batteries....so my question is; how can I recharge the expansive batterie? Thank you for your answers.

[@thecaribbean8615]

Two 12V batteries in series instead - less lossy? fuse?

[@M9A1MAN]

Just curious why couldn’t you just go straight from 12v battery to the generator if it’s meant to take in 12v? Why the need for step up? Thanks

[@Pessel-99]

Is a 3 amp converter enough for this?

[@douglaswindsor120]

This battery would work great with the natures generator solar generator. I would love to see someone do a proper review of nature's generator just think a 2000 watt pure sine wave inverter for under two thousand dollars

[@asabatelli1]

I set up everything exactly as you did with my EcoFlow Delta 2 and KiloVault lifepo4 battery. It went from 73% to 94% at just over 200 watts. Then it stopped. I discharged the EcoFlow 2 to 39% and tried again, but nothing. I put a little charge on the KiloVault battery in case the BMS had shut it down. Rechecked all connections but still nothing. Is it possible the 12-24 unit just died? It was fairly warm when it was working. Any thoughts appreciated. I may also try with a 12 to 36 or 48v, since it has a 60v max for solar input. Any thoughts appreciated.

[@ReeWrayOutdoors]

Yeah I'd check the output on that step-up converter with a multi-meter and see if it is working or not.

[@commodore1979]

My power stations dc input states 12 to 60 volts so I should be able to use a 12v to 48v step up yea?
