bought the EVE LF280K Lifepo4 cells, 16 x 3.2v cells supposedly stocked in canada.Final price ends up being a little higher than quoted because purchase goes through Alibaba. (fees for currency conversion, and trade protection)Shipping took a few days extra to start, maybe they really slip it accross border, I don't know, but was still reasonably fast, better than the normal from US or china type delays.I am happy with all the details, was packed well. Was the cheapest and fastest option I could find.I had just bought a 48v forklift with lead acid cells dead. So I pulled out each lead acid cell, then stuck in the lifepo4 cells. Cell balance board off amazon rather than full bms for now. (not sure what my max load will be, don't want to fry a bms if I exceed what it can handle) balance board is good enough for now as only use forlift for fraction of full battery capacity before it goes on charger again.it would take 58v to fully charge them. I instead opted for 4amp scooter charger, 54v so they get almost full but last much longer.I've bought a MPPT solar charger but not setup yet, will also adjust its max voltage to be 54 volt or less. It has to be hooked to batteries before solar panels, and forklift occasionally moves around doing forklift work, so have to get the setup right, with it living with the forklift with good vibration protection.Planning on also adding an all in one hybrid solar charge controller/inverter combo, where I can tune the min and max voltages for battery, so it never is completely full or empty just like they do on electric cars.***My opinion, if you can handle the technical stuff, probably better to buy cells rather than pre made batteries, because that way you know exactly what you are getting and can do better quality. Pre made ones sometimes skimp or even dishonest on the cells or bms.BMS... if you use more power than the BMS can handle for a few secs it can get hot and start wearing out. I had 24V electric lawnmower with lead acid batteries. Replaced them with Ecoworthy 30 AH off amazon, that were same size, would fit in lawnmower. One of the bms died after using for a while, so I ordered some more powerful BMS, still have to finish soldering them in to replace the wimpier ones.So far every premade 12v or 24v battery pack that I've bought and taken apart to look used inferior stuff to what I would buy and do myself. What they call in china "LTO battery" (titanium oxide, best cycling performance cells), are really the cheap 3.6V cells, 150 ah is really 125 ah, etc. Alibaba, DHGate you have protection in that seller doesn't get your money till you got correct goods (you should make sure correct), but its a bit of a gong show... you'll say it is fraud/not as good as supposed to be, seller will say accept it or ship it back, but will end up being no way to ship it back because shipping lithium cells "dangerous goods" is often gong show in canada, so he finally gives in and reduces price.Ideal larger system is 48v, because reduces cost of MPPT controllers (half the amps to charge 48v rather than 24v), if you go for premade 12V batteries in series to get to 48v you can get 12v balance board that balances the 4 x 12v batteries off amazon. If you charge to less that 100% and actively balance cells all the time (rather than just when individul cell hits 100% charge) and don't discharge all the way empty your battery pack will likely last 2x+ longer. (GM with chevy volt and then all the other car manufacturers do this)[I see most commonly bms balanced when an individual cell hits 100%, which means the weakest cell will be at 100% when charged, and likely stay at 100% much of time, which drastically shortens its life and when that one weakest cell dies, people tend to throw away the whole battery pack]
If you invest in solar, you are smart. If you invest in both solar and lithium batteries, you are even smarter. Despite the high initial investment in lithium batteries, they have superior longevity and performance. This makes them the best alternative for grid-tie and off-grid applications. When it comes to choosing a battery that fits with your solar system, it's important to understand the benefits that lithium batteries have over lead-acid batteries. Further details will be discussed below.
According to the Electronics Engineers and Institute of Electrical, lead-acid batteries' efficiency is approximately 70% to 80%. This efficiency level will be consistent throughout the life of the battery. Based on the fact that charge controllers and inverters are reaching efficiencies in the high 90s, energy storage systems that are highly efficient will be desirable. Lithium batteries exceed lead-acid batteries because their efficiency is normally 99%
Besides, Lithium batteries are also more efficient when you harvest energy from your renewable energy system. For lead-acid batteries, they have relatively low charge acceptance, which means the energy they can harvest is low so that they won't exceed the required charge currents. However, for lithium batteries, there is no such restriction. On the other hand, their harvest energy can be 100% optimized. For example, you can charge a lithium battery that has a capacity of 100 Ampere-hours with 100A.
The definition of the cycle life of a battery is a discharge followed by a recharge. This can determine how long the battery will last which is an essential measure for batteries. In terms of this measure, lithium batteries can last way longer than lead-acid batteries. For example, it will deliver about 400-600 cycles if you discharge your lead-acid battery 100% of its capacity.
However, in terms of lithium batteries, they can deliver 8,000 cycles. The reason of lead-acid battery not lasting as expected is their setbacks when being undercharged. Chronically undercharging lead-acid batteries will lead to reduction of its shelf life by 80%. This is essential because renewable energy sources are naturally intermittent. As a result, batteries will always be operating at partial state of charge. As for Lithium, there is no need to worry about this since working under partial state of charge will not cause any harm to lithium.
With lead-acid batteries, there is a strict limit of how much you can discharge your batteries. That's why you always want to over-size your battery bank. Because majority of lead-acid battery manufacturers do not recommend you discharge their batteries beyond 50%, which means your battery bank needs to be 2 times bigger than it supposed to be. On the other hand, you are allowed to discharge 100% of lithium battery's energy without any damage. Therefore, their battery bank doesn't need to be as big.
When the temperatures get low, there will be a significant impact on lead-acid batteries whereas lithium will not be affected that much.

It's important to monitor and maintain lead-acid batteries carefully. You will have to refill them and there is even a chance to face hazard risk and significant damage, if water levels drop too low. However, unlike lead-acid batteries, there is zero maintenance for lithium batteries after installation, which can save you significant amount of time and money.
In addition, Lithium battery can also save you space! For example, lithium would be the most ideal choice when you are setting up your solar application and running out of room for batteries. Lithium batteries defiantly offers batter energy storage option in almost every scenario. Let us know if you are still unsure about which type of batteries to use for your solar power storage needs. We can assist you to make the best decision that fits with your interest.
Q. What are lithium batteries used for?
A. Lithium batteries power electric automobiles, cellphones, laptops, and other devices. Due to their high energy per mass compared to other electrical energy storage methods, lithium-ion batteries are currently employed in the majority of portable consumer gadgets.
Q. How safe are lithium batteries?
A. Lithium batteries are very safe, and they are also the most popular type of battery. Lithium batteries are generally secure and unlikely to malfunction as long as there are no flaws and the batteries are not damaged. Lithium batteries may pose a fire and/or explosion risk if they are damaged or unable to function safely.
Q. Are lithium batteries environmentally friendly?
A. Lithium batteries are environmentally friendly. They have a shallow carbon footprint, and they can be recycled. The environmental benefits of lithium batteries stem from the fact that they do not contain heavy metals like lead, mercury, or cadmium that can cause health problems when released into the environment.
