Please what type of charger is recommended for a lithium ion battery (65ah)... Any recommendation please
I assume you are talking about external chargers for lithium ion batteries, get an adjustable charger and know the number of cells that makes up the battery The nominal voltage per cell is 3.7v while full charge voltage per cell is 4 2v. Set your charger between these thresholds
For example, if I have a 48v lithium ion battery having 14 cells. I will set my charger to charge till 58v.
Thanks

Is LiFePO4 Safer than AGM?

In the world of battery technology, two popular options for energy storage are LiFePO4 (Lithium Iron Phosphate) and AGM (Absorbent Glass Mat) batteries. Both have their advantages and disadvantages, but one question that often arises is which one is safer. Let’s take a closer look at these battery types and explore their safety features.

LiFePO4 Batteries:
LiFePO4 batteries are a type of rechargeable lithium-ion battery that uses lithium iron phosphate as the cathode material. They are known for their high energy density, long lifespan, and excellent performance in extreme temperatures. One of the key safety features of LiFePO4 batteries is their inherent stability. Unlike other lithium-ion batteries, LiFePO4 batteries are much less prone to thermal runaway, a phenomenon that can lead to overheating and even explosions. This is due to the stable chemical structure of the lithium iron phosphate compound.


AGM Batteries:
AGM batteries, on the other hand, are a type of lead-acid battery that uses a glass mat separator to hold the electrolyte in place. They are commonly used in applications such as marine, RV, and backup power systems. While AGM batteries are generally considered safe, they do have some limitations. AGM batteries can release hydrogen gas during charging, which can be potentially hazardous if not properly ventilated. Additionally, AGM batteries are more sensitive to overcharging and can be damaged if not charged correctly.


Which Battery is Safer?

When it comes to safety, LiFePO4 batteries have a clear advantage over AGM batteries. The stable chemistry of LiFePO4 batteries significantly reduces the risk of thermal runaway and eliminates the need for special ventilation systems. This makes them a safer option, especially in applications where safety is a top priority, such as electric vehicles and renewable energy systems.

FAQ:

Q: Are LiFePO4 batteries completely safe?
While LiFePO4 batteries are generally considered safe, it is important to handle them with care and follow proper charging and discharging procedures to minimize any potential risks.

Q: Can AGM batteries explode?
AGM batteries can release hydrogen gas during charging, which can be potentially hazardous if not properly ventilated. However, the risk of explosion is relatively low if the batteries are used and maintained correctly.

Q: Which battery type has a longer lifespan?

LiFePO4 batteries typically have a longer lifespan compared to AGM batteries. LiFePO4 batteries can last up to 10 years or more, while AGM batteries usually have a lifespan of around 3-5 years.


In conclusion, when it comes to safety, LiFePO4 batteries have a clear advantage over AGM batteries. Their stable chemistry and reduced risk of thermal runaway make them a safer option for various applications. However, it is important to handle any type of battery with care and follow proper guidelines to ensure optimal performance and safety.

Can a completely dead deep cycle battery be recharged?

In the world of renewable energy and off-grid living, deep cycle batteries play a crucial role in storing electricity for later use. However, these batteries can sometimes become completely discharged, leaving many wondering if they can be revived. So, can a completely dead deep cycle battery be recharged? Let’s delve into this topic and find out.

Firstly, it’s important to understand what a deep cycle battery is. Unlike regular car batteries, deep cycle batteries are designed to provide a steady amount of power over an extended period. They are commonly used in applications such as solar power systems, electric vehicles, and marine equipment. These batteries are built to withstand deep discharges and subsequent recharges, making them ideal for long-term energy storage.

When a deep cycle battery is completely dead, it means that it has been discharged to a point where it can no longer deliver any power. This can happen due to prolonged storage without maintenance, excessive use without recharging, or a faulty charging system. In such cases, the battery voltage drops below a critical level, rendering it seemingly lifeless.


However, the good news is that a completely dead deep cycle battery can often be recharged. The process of reviving a dead battery is known as “reconditioning.” Reconditioning involves applying a controlled electrical charge to the battery, which helps to reverse the chemical reactions that occur during discharge. This process can take several hours or even days, depending on the battery’s size and condition.

FAQ:

Q: Can I use a regular car battery charger to recharge a deep cycle battery?
A: While it is possible to use a regular car battery charger, it is recommended to use a charger specifically designed for deep cycle batteries. These chargers provide a more controlled and gradual charging process, which is better suited for deep cycle batteries.

Q: Can I recondition a deep cycle battery multiple times?
A: Yes, deep cycle batteries can be reconditioned multiple times, depending on their overall condition. However, it’s important to note that frequent deep discharges and recharges can reduce the battery’s overall lifespan.

Q: What can I do to prevent my deep cycle battery from dying completely?
A: To prevent a deep cycle battery from dying completely, it is essential to follow proper maintenance practices. This includes regularly checking the battery’s charge level, avoiding deep discharges whenever possible, and ensuring a proper charging regimen.


In conclusion, a completely dead deep cycle battery can often be recharged through a process called reconditioning. By applying a controlled electrical charge, it is possible to revive the battery and restore its functionality. However, it is important to note that prevention is always better than cure when it comes to battery health. Regular maintenance and proper charging practices can help prolong the lifespan of deep cycle batteries and prevent them from reaching a completely discharged state

Encouraged by this thread https://www.nairaland.com/6310897/just-opened-own-bakery
and with the support of the poster @ SoloChris, I was able to setup my bakery FEFLO BREAD. NAFDAC has visited the facility for inspection and I hope to get the approval soon. Needless to say that the bakery is fully off grid powered by 5kva 48vdc inverter with 4kwp and 10kwh lithium cells
Due to rising demand and the need for expansion, I just bought a brand new 25kg spiral mixer to support the fairly used that has been serving for about six months now

You could make money from your dead or swollen batteries.

200ah - 47, 000

150ah - 37, 000

100ah - 15, 000

This is for recycling purposes and the prices will be reviewed from time to time.

Many thanks

Shouldn't this advice be given with a caveat? If the battery has load always on it, then the solar charging is reduced. The higher and longer the load stays on the battery the lesser the charging it gets.
Thanks for this thoughtful caveat

The installer told me that they will not be able to efficiently charge my batteries, that I need at least four
Total battery storage of your system is 24vdc x 220ah = 5280whrs

Total wattage coming from your panels assuming 4hrs sunshine is 5720whrs

NB: You don't even need all the 5280whrs to fully charge your batteries because you cannot drain your batteries to zero.

Thanks

Thanks a lot for the time you took to explain to me. Money is an issue sha, I heard lithium batteries are quite expensive.

I plan on going for mercury batteries, heard they are quite good
Mercury batteries are good, all the attached jobs were done 2021/2022 and to my surprise, they are still working

Good morning, I want to get batteries for a 2.5kva or 1.5kva hybrid inverter. I just noticed that two 220ah batteries give a total of 440ah at 594k while four 150ah batteries gives a total of 600ah at 580k. By my local man logic, the 150ah option seems better to me cus I get about 160ah more battery capacity. Pls, those who are experts, is this my logic correct and can I go for this 150ah option?
As someone that has used, supplied and worked on almost all battery chemistries, I will advise that you look into going for LITHIUM, if of course money is not an issue.

Now back to your question, I will assume it's a solar system because the inverter is hybrid and that it's a 2.5kva 24v inverter.
24vdc 220ah flooded Vs. 24v 300ah SMF

The flooded has a total of 5.2kwh storage with 2.6kwh usable (50% DOD) while the SMF has a total of 7 2kwh with 3.6kwh usable.
Flooded is more durable and can take or withstand large charging amps while large charging amps can damage SMF chemistry.

4pcs 150ah batteries requires more installation cables and increased point of failure than 2pcs 220ah batteries, it's also easier to upgrade to 48v system by adding to more batteries and get more watthrs than converting the 4pcs 150ah to 48v and get less watthrs or be forced to add four more batteries - more expenslve.

Flooded requires periodic maintenance, the electrolyte is acidic and can damage stuffs if it spills, it's also not advised to be used in a room with little or no ventilation, outdoor use is best while SMF requires no maintenance and can be used indoors.

Personally, if those are your options, I will advise 2pcs 220ah batteries

Thanks.

NB: If cost is your only consideration when buying batteries, I'm afraid you will not get premium battery and might spend more on the long run
