This video was extremely useful and extremely helpful especially since I'm more than likely gonna buy the battleborn battery. But the calculation itself is extraordinarily helpful i deeply appreciate this video it is the best video I have seen all this topic and I keep looking and everyone explains what it is but not how to do the calculation properly I deeply deeply appreciate this video!

[@Franciscosonur]

you are a modern genius . the way that you explain is priceless . thank you, thank you. thank you.

[@rosslukeman]

Wow, I appreciate that! Thanks for tuning in, I'm glad it was helpful!

[@1972WoodridgeHighSchool-pk1qr]

You're an outstanding teacher/instructor. Thank you for the info.

[@rosslukeman]

Thanks for the kind words and for tuning in! I'm glad that was helpful!

[@rogergrenier4828]

You are doing a great job explaining this subject!

[@rosslukeman]

Great to hear you found that helpful, thanks for tuning in!

[@hinch-man482]

This video finally made me understand a subject I’ve been largely clueless about.

[@vet137]

Just found you, hey thank you!! I have a brain that is slow on numbers (good on mechanics though). I love the way you did this, I even downloaded the vid so i can watch again & study the teachings. PEACE!

[@rosslukeman]

Awesome Shep, glad that was helpful! Yes this topic can be kind of heavy on the numbers. I'm glad this video was able to be a resource for you. It's a powerful topic once you know how to run the numbers. Thanks for watching!

[@tommussington8330]

Great video and explanations in this video I shared it to a couple Facebook groups

[@rosslukeman]

Thanks for checking it out and sharing it Tom! I appreciate it!

[@Phil-dg1yg]

Great job Ross! Still one off the best help for the newbies!just want to add without encroaching on the personal choices you make for your videos, the device that measures the current, Ah, eh.. which connects online also has a consumption, so pay attention to the result, in any case of my , experience :)) , which gives extra headroom. .. what is great:))💪🏻👋🏼👋🏼👋🏼

[@rosslukeman]

Thanks for watching Phil! Great point on the power analyzer, I have seen some of them have separate plugs for their own power supply. That makes sense. Thanks for your support on this channel!

[@yogawithmadelaine822]

Really good videos for figuring how much I need. Great job.

[@rosslukeman]

Awesome Madelaine, great to hear that was helpful!

[@joeltousignant6318]

Great video! You get an even better estimation if you account for efficiency or energy losses. For example, a power converter will require power to convert the power.

[@rosslukeman]

Thanks Joel but that was covered in the video regarding the inverter.

[@samsare4740]

Another good video Ross!

[@rosslukeman]

Thanks Sam!

[@rosslukeman]

Hey, awesome! Glad the calculation part helped you out. I know the batteries are pricey and it's good to know how much you need! Thanks for tuning in-

[@JohnHenryEllis]

Excellent lecture. A whiteboard would be a good visual addition to your presentation.

[@rosslukeman]

Glad you found that helpful, thanks for the feedback!

[@MICHELDILLIONS]

Thank You , Golden explanation , from Watts to Amp hours , 100 Amp Battery 🤗💖😊🏝🏡🏖🏞🤗💖😊🏝🏡🏖🏞🤗💖😊🏝🏡🏖🏞

[@rosslukeman]

Thanks for checking out the video Michel, I'm glad that was helpful!

[@SantiagoOrta-j2k]

This videos is amazingly useful!

Great video!

Thank you!

[@ivanhoe6366]

Very nicely explained.

[@rosslukeman]

Thank you!

[@theGENIUSofART-understood]

i need MORE. thats all i need to know

[@denischarles7703]

Thank you from Brasil. Very good teacher.

[@rosslukeman]

Thanks Denis!

[@norbertt.t6444]

Great explanation - great stuff

[@ENG-VIRTUAL-CRICKET-ACADEMY]

Excellent, thanks 👍

[@rosslukeman]

Thanks!

[@kanojoe1968]

Great content !

[@rosslukeman]

Thank you!

[@davidpatrick1813]

Thank you ... It will be interesting how to pre-plan estimate use

[@rosslukeman]

Thanks for watching David, yes it can be a lot of guestimating to figure out how long things will run, but calculating something will still give you a good idea of what kind of battery capacity you need.

[@sharonferra111]

Ross. I have 4 12v sla batteries that are wired as 24v into a 3000 growatt inverter hooked to 4 230v panels 35.7(voc) i am confused about the amp hrs available. They are 190ah each. So is that 760ah x 12? The reason i ask this is because my system got very low last night and system started beeping. Anyhow if this is not the forum to ask this question please just let me know. I am a beginner and really want to understanding how to use the system and really felt like this video gave me a bit more information but still a little confused. Thanks

[@justincox7190]

Simply add the ah of each battery. You say 190ah x 4 = 760. That's it my dewd. Don't over think it.

[@evergreenlogicsltd1811]

Hello. Im from Mauritius and I've just subscribed to your channel. Can you guide me on which capacity of Lithium battery, usage capacity 90%, to run a water pump (3.5Kw 3 Phase) off grid for 12 hr.

[@236vic]

if you are drawing that much amps to run toaster its amp draw is very high for the battery causing damage to battery due to the draw? battery C rating being the draw should not be more than a certain level. to deal with this you need a capacitor between them to level out the inital draw? Can 1 use say a microwave capacitor 1.1 uf 2100vac between the inverter and battery to level out the inital draw made of the battery.

[@vet137]

The toaster runs off AC not DC (AC is 120V) The battery goes to a DC to AC inverter then you plug toaster into that but not all batteries are the same discharge rate! Check to see what the battery is rated at very important!

[@darrylm3627]

😀👍Great Tips

[@rosslukeman]

Thanks Darryl!

[@shaunkilcourse8097]

Hi I’m a truck driver and I am thinking of taking a 12v LED TV & PS4 to play for 2hrs per night! both low wattage. Really confused as to what set I need!

[@freesia7632]

Thank you!

[@rosslukeman]

Glad that was helpful, thanks for watching!

[@utube1818]

Can anyone explain to me is why at 12.0 volts my leisure battery is (apparently) deeply discharged and needs changing.

[@turdboman]

SO THE TOASTER NEEDS TO BE WIRED WITH #4 AWG ?

[@vet137]

Toaster is AC not DC it would be running through a inverter. If the toaster was DC wire size would be different

[@cayrick]

Ross here is my issue. I have a Xantrex charger inverter ( widely used in vans) on a home backup application in the event of power failure. I have 6 - 6V Trojan L16RE-B deep cycle LA batteries in series parallel to deliver 12v. I live in a tropical enviornment and these have lasted 10 years but are showing signs of fatigue. The 20 hr rating on the bank is 1230 AH. I am being specific here but would be interested in a general response on different battery types of various sizes (pros and cons). As you know there have been a lot of advancements in batt. Tech over this period and there is now a plethora of different technologies including Lion (fires), LiFePo4, LA, AGM. It would be nice to go to one location (one of your videos) and have this addressed. You do a great job in addressing various issues so this is some thought for an upcoming video.

[@TangodownNZ]

Great! Thank you

[@rosslukeman]

Thanks for watching!

What about a diesel or gas heater fan pure hour.

[@herkko61]

So, I think the highest energy consumption in a RV have: air condition, oven, refrigerator/freeze, (momentarily) coffee/hot water machine, vacuum cleaner!, power tools, ...

[@rosslukeman]

Sounds about right, those are all energy hogs! Thanks for tuning in-

[@piuserupe7407]

I like it.

[@dan32one44]

Could never have to much power just ask our government 😝😂

[@rosslukeman]

Haha I agree. Thanks for tuning in again!

[@s.mendez7160]

you could get a 4 slot toaster...

[@harrysollmer1644]

Hahaha funny 850w toaster every one I've seen is 2000w standard.

[@injectionAI]

the answer is always more 😩
