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......
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.
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.
Lithium batteries have not been in high production long enough to know if they will reach warranty periods. And models show lead acid batteries if maintained last at least half as long if not more, so considering cost is less than half on average, they are often cheaper over all than lithium. Personally i have been off grid solar for 35 years. I had lead acid batteries which lasted 16 years & were still working at nearly 100% capacity when wild fire took them. They had regularly been used to almost zero capacity thousands of cycles & still lasted 16 years. So i think all the models used by lithium battery companies to disclaim other batteries are a bit fanciful & hold little weight compared to my 16 year experiance.
I used the battery acid and the battery was ☠️☠️ after 3 years maybe quality of battery isn't good l don't know but god willing I will buy the lithium battery
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.
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.
You also have the option of OPVZ gel cells. They can handle thousands of charge-discharge cycles at a 70% DOD. Their projected life is about the same as a Lithium but at a lower cost. Yes, they are big and heavy, but once they are installed there is no reason to move them. CiYi makes some good military quality ones.
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 !
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.
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.
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.
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.
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?
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.
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
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..
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.
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?
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?
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?
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?
Its the lithium-ion that can become volcanic. Lithium iron are somewhat safer, but not completely. Lithium titanate oxide are claimed to be very safe, but store less and are very expensive.
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.
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!!!

@@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??
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.
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).
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...

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
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).
So in Africa where it it hot most times, i think i should buy Lithium.
How on Earth do you think that is true?
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.
200 ah batter lithium are under 500
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...
Lead acid is not suitable for off grid storage. The cost per watt is higher over the lifetime and they only produce 1/5 their "rated" capacity.
We would tend to agree with you in most cases for sure. Which is why almost all of our solar kits have lithium batteries now!
@@ShopSolarKits what about those Solar 8D 12-285 AGMs
Which one might catch fire??? Ev car fires are horrific, are these the same. ? Old person with no tech knowledge asking😅
That’s a dumb question
Bsr
This video is shocking
So can i change a lythium ad -30 agm lead carbon can charge no problem
I've been running a used 200ah agm for 5 yrs now. Bought it 2 years after being pulled from back up power bank!
whats the point of agm batteries larger capacity if you cant use it beyond 50%
