Hello, I have been using 12x 12v 200ah (48v) VARTA lead acid truck batteries for over 10 years and there haven't been any issues with their capacity. In the winter, I run my aircon heat pump 24/7 and use a fireplace to heat my house, and in the summer, I occasionally cool with the heat pump. In addition, I have a large refrigerator, a 50L boiler, lighting, house ventilation, a dishwasher, washing machine, TV, amplifiers, a computer, a laptop, and many other... Power-hungry devices only run when there is plenty of sunshine. It's been almost 11 years since I last paid for electricity, and my average monthly electricity consumption is 250-300kw. I also have a 3kw solar array connected to charger. The batteries cost €1700 and have long since paid for themselves.
Yeah, let as its batteries really not bad. I also have a good experience with that. I actually I had some bad experience with Lydia also a good choice for lead acid battery is to get secondhand forklift, batteries, manufactures and warehouses. Have this kind of battery you can no longer use it for the forklift but it’s still good to use for solar panel.
I have been running marine agm batteries for 7 years with no fails and need only basic components to do this, no need to monitor basic power MPPT controllers works ,I run 12 batteries witch powers my home lights tv,pellet stove, internet, and charges around 14 Makita batteries 24/7 ,fans , all my kitchen tools like blenders and such for 7 years so far with no real drop in battery life......
I just replaced the 22 year old AGM batteries at our remote off road cabin after using them to run a 48v 4KW inverter. I’m in my 70s and replaced them with more AGM batteries. The voltage never gets under 46 volts on the battery plant. There is no data on lithium batteries over a 22 year span yet and I know at my age the AGMs will probably last the rest of my life.
Yup, that's why I won't use them. My battery storage is under my house with plenty of room for AGM batteries. Also, slave child labor is involved with extracting lithium out of scetchy mines. They get paid peanuts. No thanks.
true but that's more to do with the device using it than the batteries themselves say a car can use a lithium battery just not in the engine bay, a bike can use lithium but it should cover it from the sun, many lithium batteries are from china which usually's cost focused instead of safety, if you get a high quality lithium battery with board and all, as long as you charge it correctly and dispose of it before say 8 years they're generally just as safe if not safer energy density per volume
Last year I replaced my 4x 6v GC2 bank with 4x AGM's. So I deal with the 50% rule. Big deal, been doing that for over a decade. I will not consider lithium because of winter temps. Cheers.
Saying LifePO4 battery will last 10-20 years is misleading! The battery chemistry in theory sure, however there is a complicated electronic BMS with hundreds of electronic components that can fail within the battery. The battery electronics are usually under warranty for 1-2 years for most brands. I've owned plenty of electronics that don't last more than 3-6 years. Think of modern LED light bulbs that have 30'000 hour rated LEDs. The LED driver electronics fail far before the LED. That might be the case with some BMS.
True, but if you buy a serviceable battery, you can easily replace the BMS or hire a techinician to do it for a fraction of the cost of the original battery. It's also true that most lithium batteries today are not serviceable, but serviceability is starting to become a big selling point for newer brands. Wiring a BMS is pretty basic, so the ability to replace a failed BMS DIY-style is an important buying factor IMO. Assuming serviceability is built in, it is realistic to say the pack will last 10-20 years.
My 12v 100ah battery on my solar system took a dump at exactly the 2 year mark. The warranty is 10 years, let's see if the company honors it. I think I'm going to try lithium next.
DOD of a good quality AGM battery is up to 80%. And if well looked after you can expect 10-15 years. So for $800.00 you're getting 320ah and no risk of fire. Size and weight do not matter for home use.
Didn't realize how fast 8 years went by on my AGM batteries. They were great, mostly had them in float mode and rarely used it to power up the house, wanted to save it in case of an emergency. Yhea,,,,,, well recently I noticed on inverter power I got about 15 min of run time. That's using 16 125ah bats in 24v mode.. Researched everything but the lifespan. Never got a real time use of my system btw living in florida.
We had 50 submarine batteries, lead acid, in the basement of our college, they lasted 35 years and were still in there when i left, they were still good, my friend has gone to lead acid in his home after the lipos he had failed after 2 years, now he has a problem with recycling those batteries as they hold some very nasty toxins the environment cannot tolerate and will make land virtually sterile for a very long time.
I worked in telecom and we had many battery plants that were 20-30 years old. They mostly just sit at float voltage unless there is a power outage. We had some sites where each 2v cell weighed about 700 pounds and had 1700 amp hours.
The standard convention for SLA is 10 to 15 years and I have been doing off grid batteries for over 26 years now. I still prefer now lithium - but your comment about only lasting 2-3 years is rubbish !
Into 8th year with 105 ahr led acid battery. 300 wts solar in full time living in camper. It's only powered down to cut off 3 times. Paid $375. Cheaper batteries 4 years. Bought lithium battery ALDI $410 18 months ago expecting to use it soon. But still not needed.
If Lead Acid batteries can only be discharged 50%, why do we still have to calculate with 2,400W which is it’s 100% capacity while designing a solar array to charge it? Why not 1,200W?
Lithium batteries go into thermal runaway and burst into a fire that cannot be extinguished. Lead acid this is not an issue unless you boil all the water out of the battery.
Price point. My 4x100ah are about 5 years old. Can't keep my small refrigerator on all night. They work fine still for lights, pumps and music. ? Should I make the switch and isolate my ac needs come from a separate battery bank. I can add lipo little by little if more is required as my agms die?
Bought a Van already built with the AGM. We picked up a Lithium version to replace it. While I have this AGM sitting around I'm thinking about just putting it in my Tacoma back seat to run my Dometic CFX35 full-time charge it via Alternator. Instead of having to swap my Jackery and Goal Zero out every 3-5 days. Anyone doing something similar or think I'd have an issue with this?
Hi.. between a starter LFP battery and a starter AGM battery of same Ah rating, same RC rating, same brand quality, under the same environmental conditions, at optimal temperature like 20°C-30°C and all else being identical and equal, then which of the battery would deliver higher instantaneous peak surge current?? I meant more cranking power/amps.
Did you also know that these lithium batteries are good for around 3000-10 000 cycles depending on the brand? That means that for common use, most people can get anywhere from 8-15 years of use before the batteries go down to 80% capacity. These products are not made to be replaced like cellphones and computers. We want our products to last and to remain functional for our customers so that they will be there when they're most needed!
You don't know how to charge your phone.u probably don't keep it in a 20-80 percent range.and u also have to use a certificate charger and cable.and use lower wattage chargers
One thing you didn't mention, You replace the lead acid battery for free before the warranty expires. Been doing it for decades. Use the warranty. Save your money.
Pls i jeed help in understanding Solar Batteries and inverters i have a lead acid battery of 100Ah once it hits 11V the inverter shuts off automatically so my question ❓ is if i buy a lifepo4 or lithium battery will the 12v inverter still shut down once the battery is at 11v or will the battery 🔋 keep powing my inverter even when it's below 12v which is the recommended voltage for 12v inverter to work ? Or will it keep powing my inverter till the battery completely dies off like low to zero just like how mobile phone batteries operate ?
I bought a 12V 200ah AGM battery about 15 months ago, I have a 60A MPPT CC and 2 160W 12V panels. Every day the panels charge the battery and at night for approx 9 hours I power three 5M LED light strings, battery starts of at approx 12.8V and after 9 hours use the voltage is 12.4V......or at least that's what WAS the case for 14 months. Last week I noticed that the battery voltage was 12.1V at the end of the night, now I can't use the lights for 9 hours; after about 5 or 6 hours the voltage has already dropped to 11.5V, although when I switch the LEDs off the battery voltage jumps to 12.6V......seems my Chinese made AGM battery is nearing the end after a mere 14 months!!!!!!!! Anyone have any suggestions?
The one thing that is worth knowing is that lead acid batteries are nearly 100% recyclable and widely accepted depending on why you were going off grid at this may be an excellent thing
My question is don’t AGM outperform lead acid? And can’t you use the AGM better for solar and doesn’t it also allow you to drain it further and doesn’t it charge faster than let acid?
Hi.....please if I have three 12.8v 100AH lithium....and have em connected in series to have 300AH...how will I charge em...like how many amp charger should I use ...remember the battery each has BMS inside
3 x 12volt 100AH lithium in series produces 36V at 100AH. If connected in parallel they produce 12V at 300AH if your BMS allows for parallel configurations. You would charge them with a 12V lithium battery charger. Each battery's BMS will manage the charge parameters for it's respective battery.
Ive had been using agms in my camper for 2 years, you can run them down and not be left stranded unlike with a lithium, which will just sinply shut off when it gets low .. if your systems always topped up by solar for example the only benefits of lithium are space and weight for me... I am running luthium right now but future builds maybe not ...
That's why my Duracel AGM deep cycle batteries gone bad so quickly !! I didn't know I can't discharge them bellow 50%. I use it in my electric lawn mower. I ordered lifepo now, let's see.
Electric lawn mower? WHY? they're worst in every way, heavier and cuts worst, not only that but you actually had to repair the battery so it's the same in terms of maintance
I've never seen a single gel acid manufacturer claim that you can only discharge 50% of you battery. Only lithium vendors make that claim. Actually they claim that you can discharge your gel battery up to 80% and still retain over 400 cycles, which might not be a lot, but it can be done. Not to mention lithium ones can be up to twice as expensive for hte same Ah.
Well, the "absolute lowest DOD" of the AGM is not 100Ah. Looking at cycle life charts for that battery I'm sure that even frequent 70% Discharge still gets you that same 4 or 5 years of battery life out of that AGM. Look, I have "Lithium" or LiFePO4 batteries so, I know all the pluses - but to claim that 50% DOD is the absolute minimum is just not correct and you shouldn't be stating that it is - to do so makes your entire presentation suspect for lack of honesty.
Hey Paul, appreciate your feedback and input here. I think it was more of a "suggested best practice" for preserving the longevity of the batteries than an absolute fact. Thanks again though, the more information we can out there about this, the better!
Please he is very correct!! And it is strictly 50% state of discharge only for All AGM or GEL lead acid batteries if you intend to use them more than two years..
When the battery dies you want something fast to replace it.why use mail that you have to wait for? When you can buy one at a store,walk out with,and hook up to restore system.
That is not what 10C means. 10C means you can charge a 200Ah battery with 2000A (i.e. full in about 6min). Which is incorrect. You are also confusing 10C with C10. C10 means you can charge a 200Ah battery at 20A (i.e. full in about 10 hours).
Once you've actually witnessed a fire department try to extinguish a lithium battery fire you'd think twice about using them in your rv. The RV fire i witnessed took out a 30 foot class c rv in minutes. The batteries had just been installed the solar was charging them. The owner had left with snother RVer to have breakfast. The fire started in the battery box which is in the steps of the entry. The rv was totally engulfed in flames in under 3.minutes. by the time the fire fighters got there the RV had burned completely down to the frame. That experience was enough for me to know im not doing lithium batteries anytime soon. Besides my rig was designed for lead acid batteries. Keep it simple.
Thank you. Yes it has been very helpful. I am running 100w solar panel on a 200 ah agm battery. I want to replace this with a lithium battery. Do they come with higher ah's than 200? I want to run a maxi fan and wall fan at night as well as a fridge. Thanks in advance.
We have a solar system with hybrid inverter of 5kWh, 8 panels x380w each, 2x 3,2kW or thereabouts lithium batteries (Pylontech US3000C). It runs everything except electrical oven which has now been overtaken by our airfryer. We use Eskom prepaid as backup for charging solar geyser at night if needs be. Our average daily/nightly use of prepaid is less than 6kWh per day. We plan to upgrade a bit, so as to be close to fully off-grid.
Lithium sucks in the cold. Buy a 12 v car heater and insulated well if using lithium in the freezing cold. Lithium can be destroyed in the cold. I use semi lead acid batteries. And had no troubles.
I grew up rural and my dad had a battery system he has batteries that are functioning well from 2009 its 2024. If you are burning them out after 7 years you are doing something wrong...
Your definition of "footprint" is rather peculiar - you talk about the size and weight determining footprint. I would say that footprint relates just as much to its ENVIRONMENTAL footprint. There the lithium battery has a much larger footprint (less environmentally sound)!
Try another test vs Lead carbon agm PbC, it would change the specs drastically. 100% D.O.D. possible @ 800 cycles, 50% 3200 cycles, my charge rate is 190A, no BMS, no heaters, no equalizers, -40c to 60c, sealed non spillable, 2-year storage, safe for indoor use, no risk of fire, heavy 170lbs not for mobile applications, maybe 2 at 6kwh and 340lbs. Claims of 3200 cycles may seem low but what is going to go wrong besides loosing capacity over the years, at least I know it won't burst into flames. In 2023 Massachusetts had 58 deaths from lithium battery fires *google. If any lithium battery goes thermal runaway, it is hard to extinguish, some companies put fire suppression systems in their lithium products and claim its safe, if it is so safe why does it have its own fire extinguisher?. In most cases the lithium cells are same as everyone else cells. Xterra in 3 sizes 12v100 12v250 and 6v 400 and good upgrade for any system old or new.
this guy is comparing a wrong AGM type . The correct one is marine or deep-cycle battery, it can be fully discharged and then recharged without any damage .
The thing is that we ”know” the capacity with led/acid. Lithium is today more or less numbers from the manifacturer. In theory they are way better but in real life you can be lucky or unlucky. And all those fires and deaths? How do we meassure them. A Lithium battery is a ticking bomb and people die like flies when mining, manufacturing and using them. I like them but has lately becoming a bit scared of them. Mostly because we have a HUGE battery factory in our town. The last year five unexplained deaths at the factory. They still investigate but they cant find an answer, at least not publically. If its not because of the content int the batteries its because of something we dont know. It could as much be the vaccines but as said, WE DONT KNOW!
What a load of crap omg. You shouldn’t use the top 20% of a lithium battery. The batteries are usually the same size. Ten years for a AGM. You’re keeping them in a room, the weight doesn’t matter. The cost bs. You can also buy used 1 yr old ups 200 amp hour agms for $75. 5000 wh lithiums are $2000!!!
Did you also know that these lithium batteries are good for around 3000-10 000 cycles depending on the brand? That means that for common use, most people can get anywhere from 8-15 years of use before the batteries go down to 80% capacity.

@@evertking1 Kijiji Today I just bought 10 new Eaton agm 140 ah $150 a piece I’ve bought csb 12540 out of 1 year old ups system for $200. Energy Safe 190 ah for $200. Any large bank or government building will have ups systems that change out batteries for smallest reasons. You can buy 1 yr old batteries that have been maintained and used a couple times for 25% cost of new.
@@ShopSolarKits 3000 to 10,000. Cycles. Bit of a spread. All the agm batteries I’ve bought are good for 10 years. Most will last 3000 to 4000 cycles at 50% DOD. Also within a year Lifepo4 will be obsolete with sodium ion coming out. My point is this video is incredibly biased. Even the example battery size. I have several brands of lifepo4 100ah and several brands agm 140 ah and the batteries are very close in size. Lifepo4 are significantly lighter but does that matter??
Lol, Why buy sealed AGM, buy the ones u can replenish with Acid and Water, Obviously you don't know anything about Deep Cycle Car or Truck Batteries...Also, Lithium can not work on extreme Cold and Hot Weather....c'mon man next time make a video that is "TRUE and Un BIASED.....For Example, I had a 2003 Mercedes E500, yup the battery lasted longer than the car...
2 minutes into the video already spitting out bad information let acid and AGM are not the same let acid batteries you do not want to discharge past 55% AGM batteries there are many AGM batteries on the market today that you could discharge up into the 80 to 88% off
you cant draw all of the lithium, and i have discharged agm countless times. Deeply discharged Li-Ion won't last a year, especially in storage where large ambient temperature changes are possible. It is recommended to store Li-Ion half-charged, to prevent "overcharged state" (i.e., when fully charged cell cools down to below 0C). just a brainless video. do some real in depth research, we didnt come here for a quick overview.

What about the issue of easily igniting into fire, which of the 2 is more prone to ignite?
Lithium batteries go into thermal runaway and burst into a fire that cannot be extinguished. Lead acid this is not an issue unless you boil all the water out of the battery.
SLA is more prone to ignition (from flammable vapours) than LiFePO4

Because your phone still uses Lithium ion as opposed to Lithium phosphate batteries.
Is there a minimum voltage that you can discharge the lithium batteries too?
Or can you discharge it to 0 volts?
Don't wanna go to zero. Maybe 90% tops

Last week I noticed that the battery voltage was 12.1V at the end of the night, now I can't use the lights for 9 hours; after about 5 or 6 hours the voltage has already dropped to 11.5V, although when I switch the LEDs off the battery voltage jumps to 12.6V......seems my Chinese made AGM battery is nearing the end after a mere 14 months!!!!!!!! Anyone have any suggestions?
I need it to work in the cold so AGM is best. If I lived in a warm place I'd get Li
The one thing that is worth knowing is that lead acid batteries are nearly 100% recyclable and widely accepted depending on why you were going off grid at this may be an excellent thing
My question is don’t AGM outperform lead acid? And can’t you use the AGM better for solar and doesn’t it also allow you to drain it further and doesn’t it charge faster than let acid?
Hi.....please if I have three 12.8v 100AH lithium....and have em connected in series to have 300AH...how will I charge em...like how many amp charger should I use ...remember the battery each has BMS inside
3 x 12volt 100AH lithium in series produces 36V at 100AH. If connected in parallel they produce 12V at 300AH if your BMS allows for parallel configurations. You would charge them with a 12V lithium battery charger. Each battery's BMS will manage the charge parameters for it's respective battery.
When connected in Series, only the voltage increase and the amperage remains the same. For your case you have 36V 100AH battery pack
What about heat. I love in FL and I've heard lithium doesn't like heat and can explode or ketch fire
Ive had been using agms in my camper for 2 years, you can run them down and not be left stranded unlike with a lithium, which will just sinply shut off when it gets low .. if your systems always topped up by solar for example the only benefits of lithium are space and weight for me... I am running luthium right now but future builds maybe not ...
Wow .... right to the point! In that regard, best RUclips video I have ever seen.
Yeah very rare these days
Excellent video about batteries details
That's why my Duracel AGM deep cycle batteries gone bad so quickly !! I didn't know I can't discharge them bellow 50%. I use it in my electric lawn mower. I ordered lifepo now, let's see.
Electric lawn mower? WHY? they're worst in every way, heavier and cuts worst, not only that but you actually had to repair the battery so it's the same in terms of maintance
how many lithium battery of 48v 100ah do I need if I have 18 solar panel 550w?
Depends on your power draw. Depends upon how many hours of suitable sun you get.
how come amg does better in the cold?
Can agm battery be repaired
Lithium requires more expensive bms, and lead carbon agm batteries have a very good lifespan.
So why don’t laptop batteries stop working good after a year maybe 2
Same with my smart phone
Never run the down beyond %30. They will last for years and years this way.
How safe is a lithium battery in a conversion trailer.fire risk is my main question
Very good
I've never seen a single gel acid manufacturer claim that you can only discharge 50% of you battery. Only lithium vendors make that claim. Actually they claim that you can discharge your gel battery up to 80% and still retain over 400 cycles, which might not be a lot, but it can be done. Not to mention lithium ones can be up to twice as expensive for hte same Ah.
Well, the "absolute lowest DOD" of the AGM is not 100Ah. Looking at cycle life charts for that battery I'm sure that even frequent 70% Discharge still gets you that same 4 or 5 years of battery life out of that AGM. Look, I have "Lithium" or LiFePO4 batteries so, I know all the pluses - but to claim that 50% DOD is the absolute minimum is just not correct and you shouldn't be stating that it is - to do so makes your entire presentation suspect for lack of honesty.
Hey Paul, appreciate your feedback and input here. I think it was more of a "suggested best practice" for preserving the longevity of the batteries than an absolute fact. Thanks again though, the more information we can out there about this, the better!
Please he is very correct!! And it is strictly 50% state of discharge only for All AGM or GEL lead acid batteries if you intend to use them more than two years..
@@MarkSmith-Uzor 80% is safe and will have minimal impact on life cycle, google is free.
@@tyler6971 there's a lot of misinformation out there, mainly from salesman that want to sell more. 50% is right, no less.
When the battery dies you want something fast to replace it.why use mail that you have to wait for? When you can buy one at a store,walk out with,and hook up to restore system.
thank you
Remember LFP are rated 80%
not full 200Ah , around 160Ah
Will zero-degree temperature damage a Lithium Battery?
How about the charging speed isn't agm 10c meaning needs 10 hours to discharge?
That is not what 10C means. 10C means you can charge a 200Ah battery with 2000A (i.e. full in about 6min). Which is incorrect. You are also confusing 10C with C10. C10 means you can charge a 200Ah battery at 20A (i.e. full in about 10 hours).
Once you've actually witnessed a fire department try to extinguish a lithium battery fire you'd think twice about using them in your rv.
The RV fire i witnessed took out a 30 foot class c rv in minutes. The batteries had just been installed the solar was charging them. The owner had left with snother RVer to have breakfast. The fire started in the battery box which is in the steps of the entry. The rv was totally engulfed in flames in under 3.minutes. by the time the fire fighters got there the RV had burned completely down to the frame.
That experience was enough for me to know im not doing lithium batteries anytime soon. Besides my rig was designed for lead acid batteries. Keep it simple.
You forgot the fire dangers between Lithium and AGM
Thank you. Yes it has been very helpful. I am running 100w solar panel on a 200 ah agm battery. I want to replace this with a lithium battery. Do they come with higher ah's than 200? I want to run a maxi fan and wall fan at night as well as a fridge. Thanks in advance.
Yeah, lithium typically comes in variations of 10ah, 20ah, 50ah, 100ah, 200ah, and 300ah these days.
We have a solar system with hybrid inverter of 5kWh, 8 panels x380w each, 2x 3,2kW or thereabouts lithium batteries (Pylontech US3000C). It runs everything except electrical oven which has now been overtaken by our airfryer. We use Eskom prepaid as backup for charging solar geyser at night if needs be. Our average daily/nightly use of prepaid is less than 6kWh per day. We plan to upgrade a bit, so as to be close to fully off-grid.
You will need a lithium recharger
132lbs defeated you?
the uptalk is out of control guys
Just subbed one thing is missing i think is that in 5 years the battery of the acid will be much cheaper than todays prices
NO DUDE..IT IS THE SAFETY ......LITHIUM BLOWS UP.
Lithium sucks in the cold. Buy a 12 v car heater and insulated well if using lithium in the freezing cold. Lithium can be destroyed in the cold. I use semi lead acid batteries. And had no troubles.
Don’t the lithium batteries explode?
I grew up rural and my dad had a battery system he has batteries that are functioning well from 2009 its 2024. If you are burning them out after 7 years you are doing something wrong...
Lithium batteries go Boom!
Blessing
Your definition of "footprint" is rather peculiar - you talk about the size and weight determining footprint. I would say that footprint relates just as much to its ENVIRONMENTAL footprint. There the lithium battery has a much larger footprint (less environmentally sound)!
Technically price of lithium battery cheaper than AGM😅
You are a bit confused, but it's ok
Can you leave with it after handing over money? NO.
AGM battery get damage faster in my country.Imagin 200Ah cannot run a 160watt load for 24hrs.
Here's the deal breaker. Which ones Safer?
Which one might catch fire??? Ev car fires are horrific, are these the same. ? Old person with no tech knowledge asking😅
Try another test vs Lead carbon agm PbC, it would change the specs drastically. 100% D.O.D. possible @ 800 cycles, 50% 3200 cycles, my charge rate is 190A, no BMS, no heaters, no equalizers, -40c to 60c, sealed non spillable, 2-year storage, safe for indoor use, no risk of fire, heavy 170lbs not for mobile applications, maybe 2 at 6kwh and 340lbs. Claims of 3200 cycles may seem low but what is going to go wrong besides loosing capacity over the years, at least I know it won't burst into flames. In 2023 Massachusetts had 58 deaths from lithium battery fires *google. If any lithium battery goes thermal runaway, it is hard to extinguish, some companies put fire suppression systems in their lithium products and claim its safe, if it is so safe why does it have its own fire extinguisher?. In most cases the lithium cells are same as everyone else cells. Xterra in 3 sizes 12v100 12v250 and 6v 400 and good upgrade for any system old or new.
this guy is comparing a wrong AGM type . The correct one is marine or deep-cycle battery, it can be fully discharged and then recharged without any damage .
The thing is that we ”know” the capacity with led/acid. Lithium is today more or less numbers from the manifacturer. In theory they are way better but in real life you can be lucky or unlucky. And all those fires and deaths? How do we meassure them. A Lithium battery is a ticking bomb and people die like flies when mining, manufacturing and using them. I like them but has lately becoming a bit scared of them. Mostly because we have a HUGE battery factory in our town. The last year five unexplained deaths at the factory. They still investigate but they cant find an answer, at least not publically. If its not because of the content int the batteries its because of something we dont know. It could as much be the vaccines but as said, WE DONT KNOW!
What a load of crap omg. You shouldn’t use the top 20% of a lithium battery.
The batteries are usually the same size.
Ten years for a AGM.
You’re keeping them in a room, the weight doesn’t matter.
The cost bs. You can also buy used 1 yr old ups 200 amp hour agms for $75.
5000 wh lithiums are $2000!!!
Did you also know that these lithium batteries are good for around 3000-10 000 cycles depending on the brand? That means that for common use, most people can get anywhere from 8-15 years of use before the batteries go down to 80% capacity. These products are not made to be replaced like cellphones and computers. We want our products to last and to remain functional for our customers so that they will be there when they're most needed!
Where can I get these 75 dollar batteries
@@evertking1 Kijiji Today I just bought 10 new Eaton agm 140 ah $150 a piece
I’ve bought csb 12540 out of 1 year old ups system for $200.
Energy Safe 190 ah for $200.
Any large bank or government building will have ups systems that change out batteries for smallest reasons. You can buy 1 yr old batteries that have been maintained and used a couple times for 25% cost of new.
@@ShopSolarKits 3000 to 10,000. Cycles. Bit of a spread.
All the agm batteries I’ve bought are good for 10 years. Most will last 3000 to 4000 cycles at 50% DOD. Also within a year Lifepo4 will be obsolete with sodium ion coming out.
My point is this video is incredibly biased. Even the example battery size. I have several brands of lifepo4 100ah and several brands agm 140 ah and the batteries are very close in size. Lifepo4 are significantly lighter but does that matter??
A grown up healthy guy should lift 60kg! The world is gone Arghhhh
Nice video btw :)
200 ah batter lithium are under 500
Acid batteries don't last 5 years of daily use no matter how you pamper it
So in Africa where it it hot most times, i think i should buy Lithium.
How on Earth do you think that is true?
Lol, Why buy sealed AGM, buy the ones u can replenish with Acid and Water, Obviously you don't know anything about Deep Cycle Car or Truck Batteries...Also, Lithium can not work on extreme Cold and Hot Weather....c'mon man next time make a video that is "TRUE and Un BIASED.....For Example, I had a 2003 Mercedes E500, yup the battery lasted longer than the car...
lithium batteries are becoming fire hazards ?????
There are many "lithium battery" chemistries. Lithium Iron Phosphate (LiFePo4) batteries don't catch fire and are by far the safest chemistry.
That’s a dumb question
Bsr
Perez Anna Thomas Michael Young Kenneth
2 minutes into the video already spitting out bad information let acid and AGM are not the same let acid batteries you do not want to discharge past 55% AGM batteries there are many AGM batteries on the market today that you could discharge up into the 80 to 88% off
This video is shocking
you cant draw all of the lithium, and i have discharged agm countless times. Deeply discharged Li-Ion won't last a year, especially in storage where large ambient temperature changes are possible. It is recommended to store Li-Ion half-charged, to prevent "overcharged state" (i.e., when fully charged cell cools down to below 0C).
just a brainless video. do some real in depth research, we didnt come here for a quick overview.
dont tell us we are going to satisfied by your video. if you did a good job that would happen. if you do crap, then you are just a con man.
Seems to me the one on the right is a piece of junk
Bullshit ....
So can i change a lythium ad -30 agm lead carbon can charge no problem
Thium batteris hurst in flames when overheat , lead acid batteries dont ill use lead acid
I've been running a used 200ah agm for 5 yrs now. Bought it 2 years after being pulled from back up power bank!
Hi.. between a starter LFP battery and a starter AGM battery of same Ah rating, same RC rating, same brand quality, under the same environmental conditions, at optimal temperature like 20°C-30°C and all else being identical and equal, then which of the battery would deliver higher instantaneous peak surge current?? I meant more cranking power/amps.
