Man, this was perfect timing! I got the Ecoflow Delta3 Plus I ordered and was thinking about how to extend its capacity inexpensively. Thank you, sir! o7
36v battery setups are my preference for these 500w ports on the Delta 3. Either an actual 36v battery, or 3 12v will max out the wattage of the port. There is some wattage trimmed off the top since 36v will actually charge at more than 500w, but nothing is wasted, really. I used to have the math all worked out, but 24v only charged at something like 300w and I think the 36v has something closer to 560w potential, of course being amp limited to not exceed the 500w limit of the controller behind the port. That makes for 1000w passthrough potential if you use both ports.
This is a very viable solution, thank you. I just think of the external batteries as being a replacement for solar. When the sun isn't shining, its like having the sun in a box, Granted, the "box" needs to be recharged, but as you said, this is an emergency solution to your power station running out of juice, no less than a gas or propane generator running out of fuel. Good stuff!
right on. having a small inverter generator into a high amp 24v charger is a solution on this 'buffer' battery. Litime makes a 24v 40a ac charger for $200, perfect to run off small generator like a harbor freight predator or the 'WEN 2800-Watt Dual Fuel Inverter Generator'. I bought the LiTime 24v charger/inverter cause it has UPS, Solar and high speed AC charging built in. I will use it to charge extra strings of 24v batteries that can be unhooked (anderson) and swung to a big powerbank like this.
At 8:10, when you connect batteries in parallel, you should make sure that they have the same level of charge so they have the same voltage (or close to it). If one has higher voltage, current will start to flow from higher voltage to lower voltage battery until voltage is the same. If voltage difference is high, current could get very high, so cables could burn, or battery could get damaged.
What about series, I am going to put 2 24vdc batteries in series to recharge my bluetti ac180 on my boat. Should I disconnect them while recharging then with battery charger.
Series works well if you need the higher voltage. You can also charge them while in series if you have the proper charger (in this case 2x24v = 48v charger) connected correctly. At this point you're getting more into DIY Solar which is not a bad thing ;) -- I'd probably build a cabinet for the batteries with a buss bar and make sure all my wiring was equal length etc and then run the charger to the buss bar to ensure the batteries charge correctly. That has the added benefit of charging the power station at the same time if it's got enough amperage to do so.
Love the video, and it completely opened my eyes to extending my power stations. I am definitely going the route of getting an external battery as in your video. What direct connect solar controller (panel to battery) do you recommend? Thanks.

I wish there had been a big generator - even tractor PTO driven. 😊
I bought a water bag for power loss to flush toilets until get my generator runnining to pump water and hot water heater . I have two power stations, an AC70P, 1000 w, and oupes mega 1, 2000 w. I recently purchased a 100 ah lifepo 4 and 10,20,35 amp charger.

6:10 balancing issues really aren't an issue for batteries in parallel once set up. It's critical they are balanced BEFORE hooking it all up, but once hooked up they will naturally self balance. If one battery is at a higher state of charge it will effectively start to dump its charge into the other batteries at a rate based on the voltage difference (which is why it's important to pre balance, if the voltage dif is too high, it will dump charge at a huge rate)

Thanks for the great video. I have a question I hope you can answer for me. I have an Ecoflow Delta 2 Max. I would like to purchase a 48v 100Ah battery to use in situations that you've described in your video. My question is what charger can I purchase that will charge a 48v lifep04 battery? I've seen plenty that will charge 12v/24v batteries, but I can't seem to find one for a 48v battery. Can you recommend one? Also, how many amp charger should it be? For a 100Ah battery, I would think that a 20A charger would do the trick. Thanks for the help!

To connect to there GX16MF5 connection to get maximum wattage off the battery you'll need this: amzn.to/3CHTlqg (I haven't tested this yet because I don't have the adapted cable but just ordered it myself for testing!).
Hi, Just watched your video, Confused!!! Does your Hybrid power station not have a built in Charger, My one has an 80A charger that can be run from AC or solar, so during the day it could be charging up the external batteries at 80A. or it can be set to charge your external batteries with AC during the night making use of cheaper rate electricity.
The Aferiy has an AC charger and MPPT solar input however, when utility power is out and there is no sun, plugging a LiFePo4 battery into the solar input will extend the time you can run
Filling the bathtubs--that really take me back. About hooking the two batteries to the power station: does it really matter that you connect to the positive on one battery and the negative on the other? The two negatives are connected by a wire. Something I'm missing?
If you're doing this for a one time thing, no biggie, but if you're going to set this up for a few weeks, months, or permanently, then yes, you need to have one cable on each battery so they charge or discharge evenly. Otherwise you wear one battery out faster.
@@stevepriority4219 Hmm. The two negative terminals, for example, are connected with a very low resistance wire, so I'd think connecting to one would be equivalent to connecting to the other.
I'm not an electrical engineer but everything I've read on battery banks (and learned in my 3 decades in Telecom with DC power) is that it is always best to draw from the bank off separate batteries with equal length conductors to ensure the draw is even across the battery bank.
I decided to pick up a 280ah LiFePo4 for this specific purpose, keeping an aging Goal Zero Yeti going more than it's rated 1400wh to keep a fridge/freezer and Comms powered-up. Now, I need the thread's recommendation on an inexpensive Battery Monitor. I can spend $100 and get Victron, which seems like overkill for my use (putting this battery on it's charger once every month to top it off and hoping I never need to use it), but the inexpensive branded example from the battery company I purchased (Eco Worthy) is getting some pretty iffy reviews on Amazon regarding ease of use and setup. Thoughts? TY!
We can't see the batteries the whole time you're talking. I don't understand what you did with the 3rd cable where you connected the negative to one and the positive to another battery, what did you do with that 3rd cable? Where did you put it or connect it to?
@@TheOldJarhead are the watt cycle 300 ah mini the best in terms of price size ?. The size being it's most impressive feature IMO? But is there better?
I think the Watt Cycle is a good battery as are LiTime, XZNY, Redodo and others (all about the same I think) so this one amzn.to/3Z9itxO (which may be what you looked at) is a great price for the AH it has. This one www.redodopower.com/products/12v-300ah-lithium-battery?ref=iiplxgbc has some discounts that aren't shown but again, I think the Watt Cycle might be the best deal (haven't looked at the other black Friday deals).
hehehehe. he is stressing that its for emergency.. while me with my poor butt.. considering any way i can SAVE and get to turn the monopoly that runs my country into my backup instead. right now im planning a modular approach. 1 room at a time. currently im using a oupes mega 1 with 600w of lvyuan panels *(200w) just for daytime reduction. plan to get batteries as my pocket allows.. and expand. i love this guys videos, jarhead, will prowse, everyday solar. jasonoid are always great to watch.
@ variable both in and out. Comes with an app to select the power station you are using (all brands) and selects the output to max that the solar port can handle. Hook the input to a 12v battery and pass the max solar thru.
Any idea if it would be a problem to charge those batteries via solar with a seperate charge controller, while connected to the power station at the same time?😊
what confuses me is, what advantage is there in having a 24v battery over a 12v? I have an ecoflow delta 2, and I'm trying to figure out what I need to get to run my fridge and freezer(about 240 watts per hour all together) for 24 hours before needing to recharge them with my generator and/or solar panels. I was going to get a 12v 300ah battery, but now I'm not sure if that's what I should get or not. maybe 2x 12v 100ah batteries in parallel, that I can swap out with another 2 12v 100ah batteries in parallel, so I can charge 2 while the other two are running the delta 2. but the whole 12v vs 24v(or 36v and 48v) is confusing me as to my best option.
Since watts are calculated by multiplying volts times amps and the Delta 2 has a max of 15 amps, the limiting factor is the battery voltage. A 48v battery would be best and should allow the full 500w since 51.2v x 15a = 768 vs 25.6v x 15a = 384w
When you get into the bigger power stations the solar rules change. For example my mango power e has a solar requirement of 60-150v dc 20amp max and 2000 watt max. How about a solution for those scenario's? ;) Funny how solar inputs are always much smaller than the 110v option.
For me, at that point I'd just go with DIY Solar setup instead which would be less expensive and have a lot more power. However, for a system like that, two 51.2v LiFePo4's would do the trick :D
I've going to look into buying one of the XZNY 310AH for use with my Eco flow Delta 2 power stations. The XZNY 310AH has much more capacity then the Delta 2 smart battery and is priced nearly the same. Thanks for the video.
That's what we heard on the radio but after making the video we heard it was downgraded to 9000 people. Doesn't matter though, as the principle is the same and it isn't like we all haven't been without power :D
Ok thought so. I was thinking adding the bluetti charger1 to boost charge from 12vbattery. I run a bluetti ac180 and a 25.6v 100ah diy. Waiting on the 200 elite. But I will basically solar charge the diy and trickle charge the 2 bluettis
They have the DC to DC charger but I like the Redodo for $40 less and it has an MPPT built in for solar. Either way, I also like multiple means of charging them up.
Haha, you saw my response meant for another, but yes! Prayers to all! If you didn't see the video on the Redodo, it's the one about my camper a few days ago. I will be installing that unit in my Jeep and love that it can take 600w of solar! Woot!
I use this method all the time. But please put a fuse inline near the battery terminal for each cable going into a power station. Usually a 15A fuse is plenty but check to see what the power station pulls. Hanging a lot of thin cables off a battery without proper fusing is a recipe for a fire. In anycase, since the power station typically limits at 8A or so, I prefer using a 24V (25.6V LiFepO4) battery. I don't generally series 12.8V LiFePO4 batteries. Better to use the proper higher native voltage instead. So at 12.8V you'll typically get 90W to 120W charging. At 25.6V you'll typically get 180W to 240W charging. If the power station can accept 60V+ on its input, then plugging in a 51.2V LiFePO4 battery will get you 360W-480W charging, roughly. And of course a power station that can charge faster than 8A or 10A... like 15A (some of the EcoFlows for example), will charge even faster. Great point on charging multiple power stations. A large LiFePO4 battery has a lot of current capability. If you think about it, a battery that can push 100A (or more) and a power station that eats only 8A... that single battery can charge 12 power stations at once without even breathing hard. BMS current capabilities really depend on the application. High-burst-current capabilities are very dangerous. If you parallel multiple batteries together the combined burst current their BMS's will allow can overwhelm a smaller cable. That is, the cable resistance can be too high to actually hit the high-end current limit so the BMS's will happily sit there for 30-60 seconds while the cable catches on fire. Another problem paralleling high-burst-current batteries is that the combined current might exceed the I.R. of your fuses, requiring a more expensive fuse for safety. So most regular batteries only allow bursting up to 2x the battery rating. Most notably, a 100Ah battery typically has a 100A BMS capable of bursting to 200A, and even though it can do more the BMS is programmed to trip off immediately above 200A. A trolling motor or golf-cart LiFePO4 battery might have a BMS configured with significantly higher trip points to handle the motors, but those batteries should generally NEVER be paralleled beyond two batteries due to the fire risk with smaller cables not instantly tripping-off the BMS. Some LiFePO4 batteries don't have over-current protection at all and are very, very dangerous because of that. A LiFePO4 cell can typically source 1000-3000A of current in a dead short. If you need lots of power, you do it with a higher voltage battery. e.g. a 48V (51.2V LiFePO4) 100Ah / 100A battery running at 100A can push 5000W continuously. To do that with 12.8V you would need a 400A BMS and 400A cabling... yuch. -Matt
I use breakers in all my power setups and agree 100%. For demonstration purposes I'm just hooking up the battery to show what you can do, but yes, they should always be fused. As for charge factors, also agree (which is one reason I put in the step up converter in the description of the video. I have no problem paralleling or putting batteries in series and have done it for a very long time. In fact, XZNY and all other battery companies provide guidance on doing so and while I agree, today it's easy to just buy a 48v LiFePo rather than put on in series, I can't lift those bigger batteries anymore. So, putting 4 12v batts in series works for me ;) But to each their own. This video is merely a demonstration of what can be done. Personally, I think tossing the PS and building your own is better :D
@@TheOldJarhead Yup, mostly agree.. though just being a higher voltage does not make a battery heavier. A 200Ah 12.8V battery has exactly the same energy capacity as 50Ah 51.2V battery. Same capacity, same weight, 1/4th the current, and 1/16th the thermals. And putting the higher voltage batteries in parallel is far more robust a solution than putting lower voltage batteries in series. And easier to scale-up later on as well (just add more batteries one at a time, in parallel). -Matt
@@junkerzn7312 Matt, great insight to safety. I have an Ecoflow Ultra, low side PV minimum 30-150v 15 amp max, my chosen battery is 51.2v 25 amps lithium. If I put (2)in series for 51.2v 50 amps output, do I use a 50 inline fuse? Also, the internal mppt will only allow 15 amps max@ 1600 watts. Just trying to select the correct fuse for the load. Thank you
I agree. It's hard to imagine the worst case scenario, however, it's easy to imagine days without power because I've already lived that many times ;) and I wouldn't even say a 'brown out' as that usually implies periodic outage due to saving energy, I'd say 'extended, unplanned, power outage' because those will happen.
Man, this was perfect timing! I got the Ecoflow Delta3 Plus I ordered and was thinking about how to extend its capacity inexpensively. Thank you, sir! o7
Cool! You can really crank out the power this way and with two 280AH or 310AH batteries in series you'd be able to run a LONG time!

That makes for 1000w passthrough potential if you use both ports.
12.8x3 = 38.4v x 20a = 768w -- if limited to 500w I'd go with the 25.6v option and keep the voltage below the MPPT threshold :D

Do I need to disconnect the battery from the power station to recharge it?
Nope :D Just plug in a charger and as long as the charging voltage isn't higher than the solar input it will be fine!
Will the Aferiy’s internal charger charge the batteries please?
Not while connected to the solar port.
hehehehe. he is stressing that its for emergency.. while me with my poor butt..
considering any way i can SAVE and get to turn the monopoly that runs my country into my backup instead.
right now im planning a modular approach. 1 room at a time. currently im using a oupes mega 1 with 600w of lvyuan panels *(200w) just for daytime reduction. plan to get batteries as my pocket allows.. and expand.
i love this guys videos, jarhead, will prowse, everyday solar. jasonoid are always great to watch.
thanks so much!
Do you have an opinion on the new BLUETTI Charger 1 Thats similar to what you are doing here ?
Great video… thank you
I haven't seen it but they make good products so I'm sure it would be a good unit to have. What's the rated wattage on it?
@ variable both in and out. Comes with an app to select the power station you are using (all brands) and selects the output to max that the solar port can handle. Hook the input to a 12v battery and pass the max solar thru.
Nice
Any idea if it would be a problem to charge those batteries via solar with a seperate charge controller, while connected to the power station at the same time?😊
You should be able to do that no problem!
Wow!
Wow indeed!
what confuses me is, what advantage is there in having a 24v battery over a 12v? I have an ecoflow delta 2, and I'm trying to figure out what I need to get to run my fridge and freezer(about 240 watts per hour all together) for 24 hours before needing to recharge them with my generator and/or solar panels. I was going to get a 12v 300ah battery, but now I'm not sure if that's what I should get or not. maybe 2x 12v 100ah batteries in parallel, that I can swap out with another 2 12v 100ah batteries in parallel, so I can charge 2 while the other two are running the delta 2. but the whole 12v vs 24v(or 36v and 48v) is confusing me as to my best option.
Since watts are calculated by multiplying volts times amps and the Delta 2 has a max of 15 amps, the limiting factor is the battery voltage. A 48v battery would be best and should allow the full 500w since 51.2v x 15a = 768 vs 25.6v x 15a = 384w
@@TheOldJarhead i appreciate the fast response and all the great info. thanks.
You bet!
Could you give us links for all the cables you’re using?
Yes! Sorry I missed those -- here they are: XT90 cable amzn.to/3AwPPhE and XT60 cable amzn.to/4eioXzV -- I'll put them in the description too. Thanks!
@@TheOldJarhead Thanks, that’s reallly helpful.
You bet!
Remember to have the correct charger for your battery. Lead acid vs lithium charger.
You are absolutely right!
love it
Thanks!
Can you just use 12 volt batteries?
as long as the voltage is above the minimum of the solar input.
When you get into the bigger power stations the solar rules change. For example my mango power e has a solar requirement of 60-150v dc 20amp max and 2000 watt max. How about a solution for those scenario's? ;) Funny how solar inputs are always much smaller than the 110v option.
For me, at that point I'd just go with DIY Solar setup instead which would be less expensive and have a lot more power. However, for a system like that, two 51.2v LiFePo4's would do the trick :D
Who do you buy your rigid solar panels from and what wattage size rigid solar panels do you like to use?
I bought my panels from sunelec.com in AZ, and if I were buying today, I'd look for 409-509w 36-47v panels
I've going to look into buying one of the XZNY 310AH for use with my Eco flow Delta 2 power stations. The XZNY 310AH has much more capacity then the Delta 2 smart battery and is priced nearly the same. Thanks for the video.
AWESOME, you'll love the added power!
12V is such a SLOW charge tho. Could use a buc converter to upvolt it. Or just get a 48V battery (25Ah is just $220) and get 500W+ charging.
@goodcitizen4587 Correct. For the Aferiy an up convertor to 24v is the ticket as you amwillvgwt 512watts
Western Washington wasn't without power recently
That's what we heard on the radio but after making the video we heard it was downgraded to 9000 people. Doesn't matter though, as the principle is the same and it isn't like we all haven't been without power :D
Can only push 12v at 10amps no?
The Aferiy can take 20A but it was about full and ramps down. I've seen it draw 512w from a 25.6v battery
Ok thought so. I was thinking adding the bluetti charger1 to boost charge from 12vbattery. I run a bluetti ac180 and a 25.6v 100ah diy. Waiting on the 200 elite. But I will basically solar charge the diy and trickle charge the 2 bluettis
They have the DC to DC charger but I like the Redodo for $40 less and it has an MPPT built in for solar. Either way, I also like multiple means of charging them up.
I might need to look at the redodo. That bluetti stuff is expensive hahaha. From Fl. Prayers to those in nc and tennessee
Haha, you saw my response meant for another, but yes! Prayers to all! If you didn't see the video on the Redodo, it's the one about my camper a few days ago.
I will be installing that unit in my Jeep and love that it can take 600w of solar! Woot!
I use this method all the time. But please put a fuse inline near the battery terminal for each cable going into a power station. Usually a 15A fuse is plenty but check to see what the power station pulls. Hanging a lot of thin cables off a battery without proper fusing is a recipe for a fire.
In anycase, since the power station typically limits at 8A or so, I prefer using a 24V (25.6V LiFepO4) battery. I don't generally series 12.8V LiFePO4 batteries. Better to use the proper higher native voltage instead. So at 12.8V you'll typically get 90W to 120W charging. At 25.6V you'll typically get 180W to 240W charging. If the power station can accept 60V+ on its input, then plugging in a 51.2V LiFePO4 battery will get you 360W-480W charging, roughly.
And of course a power station that can charge faster than 8A or 10A... like 15A (some of the EcoFlows for example), will charge even faster.
Great point on charging multiple power stations. A large LiFePO4 battery has a lot of current capability. If you think about it, a battery that can push 100A (or more) and a power station that eats only 8A... that single battery can charge 12 power stations at once without even breathing hard.
BMS current capabilities really depend on the application. High-burst-current capabilities are very dangerous. If you parallel multiple batteries together the combined burst current their BMS's will allow can overwhelm a smaller cable. That is, the cable resistance can be too high to actually hit the high-end current limit so the BMS's will happily sit there for 30-60 seconds while the cable catches on fire.
Another problem paralleling high-burst-current batteries is that the combined current might exceed the I.R. of your fuses, requiring a more expensive fuse for safety.
So most regular batteries only allow bursting up to 2x the battery rating. Most notably, a 100Ah battery typically has a 100A BMS capable of bursting to 200A, and even though it can do more the BMS is programmed to trip off immediately above 200A. A trolling motor or golf-cart LiFePO4 battery might have a BMS configured with significantly higher trip points to handle the motors, but those batteries should generally NEVER be paralleled beyond two batteries due to the fire risk with smaller cables not instantly tripping-off the BMS.
Some LiFePO4 batteries don't have over-current protection at all and are very, very dangerous because of that. A LiFePO4 cell can typically source 1000-3000A of current in a dead short.
If you need lots of power, you do it with a higher voltage battery. e.g. a 48V (51.2V LiFePO4) 100Ah / 100A battery running at 100A can push 5000W continuously. To do that with 12.8V you would need a 400A BMS and 400A cabling... yuch.

I use breakers in all my power setups and agree 100%. For demonstration purposes I'm just hooking up the battery to show what you can do, but yes, they should always be fused. As for charge factors, also agree (which is one reason I put in the step up converter in the description of the video. I have no problem paralleling or putting batteries in series and have done it for a very long time. In fact, XZNY and all other battery companies provide guidance on doing so and while I agree, today it's easy to just buy a 48v LiFePo rather than put on in series, I can't lift those bigger batteries anymore. So, putting 4 12v batts in series works for me ;) But to each their own. This video is merely a demonstration of what can be done. Personally, I think tossing the PS and building your own is better :D
@@TheOldJarhead Yup, mostly agree.. though just being a higher voltage does not make a battery heavier. A 200Ah 12.8V battery has exactly the same energy capacity as 50Ah 51.2V battery. Same capacity, same weight, 1/4th the current, and 1/16th the thermals. And putting the higher voltage batteries in parallel is far more robust a solution than putting lower voltage batteries in series. And easier to scale-up later on as well (just add more batteries one at a time, in parallel).

Great point
Great insight. Thanks for sharing
@@junkerzn7312 Matt, great insight to safety. I have an Ecoflow Ultra, low side PV minimum 30-150v 15 amp max, my chosen battery is 51.2v 25 amps lithium. If I put (2)in series for 51.2v 50 amps output, do I use a 50 inline fuse? Also, the internal mppt will only allow 15 amps max@ 1600 watts. Just trying to select the correct fuse for the load. Thank you
90% of us should prep for a brownout situation and not an Armageddon.
I agree. It's hard to imagine the worst case scenario, however, it's easy to imagine days without power because I've already lived that many times ;) and I wouldn't even say a 'brown out' as that usually implies periodic outage due to saving energy, I'd say 'extended, unplanned, power outage' because those will happen.
u left out how george washington found Merica
Well since GW did not find America, why would I include that?
Connecting to one terminal on each battery or connecting to both terminals on one of the two batteries makes absolutely zero difference.
Incorrect. By connecting to one on each you force it to draw off both equally.
happy Liberation Day everyone!
Amen!
