- I'm at it again with powering this 7 cu.ft. freezer with a 12v 100ah Lifepo4 Battery! This time I really wanted to see the difference from when I did this test before. I tested it before when the freezer was brand new. It didn't have anything in it and it wasn't even cold!
This time it's 1/3 full and frozen food. The question is.. will it last longer than 31 hours?

I live in panglao island in Philippines and we have a low wattage freezer , its very hot here and our freezer is a working freezer, we sell ice, when we put the water bags into the freezer the power draw is very high, 8-10 A , dropping a bit obviously as the water freezes , we usually get 10 to 12 hrs from our 100 ah battery , we get regular power cuts here. I like your vids sir, very informative, Thanks
Thanks for sharing! That is a great use of a battery. How long do the power cuts last?
@@OffGridBasement we have had a few that last months, infrastructure damage after an earthquake and major storms an such , then there is a lot of day here an there type deals, Im from Scotland married to a Filipina 15yrs now.
America is getting ready to have mandatory power cuts all the time by the end of summer...since the administration is hell bent on getting rid of natural gas and going to solar and wind.
Hello. Question. How many hours do your freezer takes to freeze 50 bags of water to sell as ice bags..I'm in Haiti I do understand...
Hello can you share the name of your low watt freezer..Inquiring Minds...
Almost 37 hours! That's good to know if you ever lose power. Having the freezer already running and stocked with frozen food really made a difference in run time.
It really is amazing that you can get an additional 5 hours of runtime. Thanks for the comment!
I keep 4 gallons of water in mine to provide stabilizing thermal mass and as a last resort drinking water
A great real-world scenario.
I would imagine that most people in a power outage situation, would have some product in their refrigerator or the freezer, which would help maintain that cooler temperature. Obviously your results would change, depending on the age and style of the freezer, but still goes to show that you can get quite a bit of life out of a 100 amp hour battery as a back up power source.
Thanks!
I find it amazing just how much you can do with smaller batteries. The portability of lifepo4 is just great! Thanks for the comment.
Just today I left a comment on your first 7 cu.ft. freezer video, then I found this video. I'll leave a brief recap of my other comment. ( Okay, I lied. I'm genetically incapable of leaving brief comments, so sorry 'bout that.) Your freezer has a lot of low density foods like frozen snacks. Also, as you noted, it is only about 1/3 full. I suggest that you always keep it full by using 2 liter bottles filled with water, maybe lining the bottom of the freezer for 2 or 3 layers. That will provide a flywheel effect that will reduce the cycles of the compressor. Take them out as you need more room in the freezer and as long as you used potable water, you can have a cold drink. Using an inverter to power JUST the freezer, in an outage, will work best if you use a smaller inverter and make sure that it's one that doesn't have 12 volt outputs or USB. These cheap inverter aren't very efficient to begin with and smaller ones waste less power and powering outputs that aren't AC just wastes battery energy keeping those outputs active, but unused. To get the most from your setup in a "geez, I don't know if the power will ever come back on" scenario, charting the on/off cycle of your freezer now will let you duplicate it manually by turning the inverter on and off during an outage. That way you save all that wasted standby power that the inverter uses just because it's turned on and waiting for something that needs power to tap into it. Any unused quilts and blankets that you can drape over the freezer will allow you to go several days before you even have to worry about powering the freezer, provided you kept it full before the power went out. Now set aside 5 or 6 days, drink lots of coffee and use my suggestions to see how long you can really go. Just kidding, but the things I mentioned will definitely extend the life of your frozen food in an outage. Done it and got all the Tee Shirts. Ice storms and tornadoes are both pretty common where I live.
I hope everyone reads this comment. It is full of great information. Thank you so much for taking the time to comment.
Can confirm from extended power outages. Depending on the weather a chest freezer that was at standard chest freezer temp can remain frozen when unopened for 2-6 days without power. Blankets can probably add an extra day.
Excellent video, real life scenario.
I’m a huge proponent of using shunts in projects like this.
Thank you
I'm glad you enjoyed it. I love real life scenarios.
You can run it for 1 hour and then off for 2 hours. This will maintain your freezer and preserve your battery for longer run time usage. I do this in my off grid cabin.
Thanks for the information and the comment.
This guy is my hero 😊 great video
Hahaha! Thanks!
love this type of video, thank you 😊
Glad you enjoyed! You're very welcome. Thanks for the comment.
Some very moderate battery support from solar and/or wind power would extend that run time significantly.
Yes. It could easily double or triple the time. Thanks for the comment.
Thanks for the demonstration. I suppose you could run it for 12 hours then shut the inverter off for 12 hours or so then repeat the cycle. Your food would still stay frozen as long as you’re not opening the freezer and you would get more than 3 days off a single battery
I'm sure you could. I would test it a couple times to make sure the food doesn't get above 32 degrees. I'm also not sure if it would cause strain on the freezer.
You'd still use the same amount of power possibly even more.
I would like to see this exact same test done, except that you add the thermometer and external tempature controller with it set to run that freezer at refrigerator tempatures.
Thanks for the comment. This freezer is now full! I'd need to get a second one to test that.
Love the video..exactly what I want to do.
Thankyou
Glad you liked it. Thanks for the comment.
interresting test i wanted to know this also thanks for testing it.
Thanks for watching!
i always replace the mechanical thermostat with an electronic one on all of these fridges. way more accurate and saves power , also prevents frosting to some extent .
Thanks for the info and the comment!
Thanks so much for the 2 shows
I learned a lot from the videos again thank you very much
So nice of you! Thanks for the comment.
I've been thinking of doing this with a current large chest freezer we have access to,not very energy efficient currently because of age but that can happen later,you mentioned you had no alerts or beeping from the inverter or the battery monitor which was concerning so what came to mind was a similar test with one of the Renogy 100w Bluetooth/mobile app monitoring batteries or even there newer 200ah batteries obviously cost will always be a factor but reach out to renogy and see what tests you can do with them,my freezer however runs in watts (w) up to I think 200w an hour but more monitoring is needed for me I think...keep up the tests you got this
Thank you for the support. If that freezer uses 200wh then with a 100ah 12v lifepo4 battery you should be able to get a good 6 hours of runtime. Let me know what you find. Thanks for the comment!
@@OffGridBasement I am only roughly after a 12 hour solution in my initial plans but then expanded it to 24 hours but 6 hours I hadn't calculated in my workings back to the drawing board I think,I was thinking of continuing to top it up with a smallish solar panel also,but I'll see what I can find results wise.
nice still new but starting to get the hang of it pretty much basic simple division and multiplying amps watts hours and can calculate the power source you need for type of things you want to run.. ... now i can get a 3 100w solar panels and each panel puts close to 5.5amps so total ill get 16amps an hour putting it on a 12v 100ah and i should be able to fun a freezer like yours maybe even a slight bigger with no issues and go off grid on it along with powering up 12v lights and charing other things.. maybe ill get a 2000w inverter because ill be running other small stuff and maybe get 2 100ah 12v battery and this should run good since i live in california we get lots of sun... very good info seems like i dont need a shunt after all i can just use my amp meter and i can just calculate from there if i need more solar or battery ect.... very simple thank you
Looks like you are on the right track. With the equipment listed you should be able to run the freezer no problem. Thanks for the comment.
I enjoyed your video on the freezer. I was wondering, how long would it run if you added one 100 watt solar panel on it.
That really depends on the weather. A nice sunny summer day could possibly add another 12 hours.
Great Stuff Bro. Could you please give a link for the monitoring unit? Warmest Regards. SHMUEL.
I have all my links in the description. It's the DC monitor link. Hope that helps and thanks for the comment!
Excellent video. I'm a new subscriber.
I would be interested in knowing how long the battery would last if there is an insulating jacket covering the freezer. A jacket could be made from the same material used to to insulate camper vans and window blinds. Just a thought for one of your videos. Cheers!
Thanks for the idea and comment!
Most chest freezers use the exterior skin to radiate heat from the condenser.
Beautiful
Thank you! I hope it helps somebody. Thanks for the comment.
i bet half the power use in this test was just the inverter. 12v dc fridges have come down in price considerably in the last 2-3 years. 1400 dometic now you can find 100$ on walmart's website. got some random brand kapas 54 quart fridge for 99 bucks on sale. added insulation to its base and covered it in IR reflective aluminum foil tape. it uses about 0.2kwh/day or 16ah/day in 12v land. its insanely efficient. most fridges use about 1.5-3kwh/day. currently rigging up a usb-c gan charger to run it since they have like 10x less losses than regular brick power supplies. trying to get it to around .1 kwh/day. for example this battery would power it for 2+weeks and wouldnt require an inverter.
Thank you for the great information and comment.
Love this video
Glad to hear! I'm always amazed by the results. Thanks for the comment.
@OffGridBasement I wish I cude do want you do but on a budget so can you make a video about a budget lifepo4 battery I am in the uk
Very nice
Thanks
And if you connect a 200 watt solar panel to it with a charge controller it will run forever!!!!!
On sunny days it sure would! Thanks for the comment.
@@OffGridBasementyou still get juice on cloudy days (with modern panels), just less of it.
I really need to take measurements this fall, I just started in solar and I live in the pnw where I know I'm going to need to overpannel for cloud cover 🤣
I'm considering doing this as I have two spare 90 watt panels and a spare 1500 watt inverter and controller. I just need to get the freezer... 😀 Don't see why it wouldn't run forever.
You're not using a pure sine wave inverter? My chest freezers are all 12 volts, except for a 5 foot that should get traded away.
The ALFFAA inverter is a pure sign wave inverter. I would like to get more 12v appliances because they are so much more efficient. Thanks for the comment.
@@OffGridBasement Ten - Four. Don't forget the tiny Honeywell Quiet Set fan. I have one here. I love my 12 volt chest freezers and CB radios.
Dies the inverter play into the scenario..
I have an 800 amp inverter with a 7.0 chest freezer.
It will a little bit. Standby energy consumption is going to be the biggest issue with the inverter you use. Thanks for the comment.
Anyone Ever tell ya you look like the Actor David Morrissey, you look like a younger version of him, He played in the walking dead, The Governor.
My son agrees with you, but I'm still not too sure. Thanks for the compliment though!
May I ask if you think there is something in this battery costing $500 that makes it worth more than the $300 ones?
The unowix does have an active cell balancer and cold charging protection. It probably also has higher grade cells and BMS. Hope that answers your question. Thanks for the comment!
I will answer, nothing
2:21 do you keep inverter on floor? I’m concerned about water damage from anywhere, not just a fridge or freezer.
If it is a permanent setup then you would want it elevated. Thanks for the comment.
Im a new scriber, im trying to buy a deep freezer,any adwise before I buy a deep freezer?
My only advice is to get one size bigger than you think. Mine is filling up fast!
So it cannot be done w a regular battery? I have a new 5000W inverter but my cooler shuts off.
The amp draw might be too much. The voltage is probably getting too low for the inverter so it faults.
HOW CAN I CALL THE MATERIAL MEASURING THE BATTERY
It is called a battery monitor or a shunt.
Looking at the voltage of 13.7 and stating it's 100% full based off of it is old school lead acid battery thinking. It's a lithium battery and voltage never indicates SOC. Also, the dip (voltage sag to 12.2v) wasn't too impressive for a lithium battery with such a smallish load.
You're right about the 12.2v lag. I really need to find out what the initial draw of the freezer is. After testing multiple Lifepo4 batteries I know that full is 14.6v, but then it settles at 13.7v after resting for a few hours. Thanks for the comment.

I wish! Maybe I should contact them!? 😁
I just bought a 100ah lifepo4 and tested on my freezer at 13.6v
Freezer is comsuming about 125watt and it seem could last only 10 hours on my lifepo4 battery till it run down to 12.3v
Is my battery a low grade cell?
Thanks
That makes sense. If the fridge is using 125w per hour and the battery is rated for 1280wh then you would get right around 10 hours of use.
@@OffGridBasement But how come in yr video a 100ah battery last for 36 hours where mine only last for 10 hours
@@Lee-Fiz I'm not sure. I don't understand why your freezer uses 125w per hour. It should be a lot less. It should only use that for about 15 - 20 minutes every hour. That would make it so it's only using about 42w per hour which makes more sense. I don't believe there is anything wrong with the battery as long as it's getting charged up to 14.2v.
@@OffGridBasement Yes it uses 15-20 minutes, tht is how freezer works right...but each time the motor kicks in my inverter display show 125w and gradually goes to 110w and tht is the lowest it would go till it stop.
I notice tht my charge controller will charge as high as 14.4v but when it is fully charge my battery will go into flooting charge about 13.4v I wonder if this hv made the battery less wattage to run my freezer at night
@@Lee-Fiz everything you are telling seems to be right. Float @ 13.4v is good. I think you need to purchase a watt meter to measure how much energy is being used on the AC side. If the battery is shutting off and the watt meter only reads a total of 500wh then something is wrong with the battery or the inverter is pulling A LOT of standby wattage.
Even longer if the freezer took 12 volts
Yes. There is AC conversion loss at the inverter. Thanks for the info and the comment.
Is this the type of batteries used in a car?
No. This is a storage battery. Car batteries are designed to give a short burst of a lot of energy. This is for drawing the energy out of long periods of time.
How can i get it...
Any 100ah lifepo4 battery and 1500w inverter can do this.
@@OffGridBasement ok my dry 200Ah cant even handle my freezer for 2hrs at night
What is yr freezer wattage?
It runs 1.7 amps @ 115v. That would equate to 195w while actively cooling.
I would add solar to it
Yes! Even a 100w solar panel would make a huge difference! Thanks for the comment.
Imagine if it was full and covered it in blankets or insulation. Fill it with frozen gallon jugs and repeat please
I've noticed a lot of people recommend that. I have to give it a try. Thanks for the comment.
Add some panels, and show the results..
Good idea. Thanks!
Obviously you didn't have to account for the energy used to freeze the 1/3 load, a no brainer it will last longer.
Yes. The question really was how much longer. Thanks for the comment.
Please I really enjoy your videos.
Please help me with pressing iron of like 1000watts.
Please.
Thanks🙏
Are you wanting to know how long it will power the press or what type of inverter to use?
And what does your wife think? She must have noticed too
She doesn't mind as long as I don't break anything! Thanks for the comment.
