In July of 2021, a little-known startup in the portable solar generator industry established itself as the new industry leader. This, of course, was the introduction of the EcoFlow Delta Pro, the most powerful portable power station of its kind. Since their world-record Kickstarter campaign, EcoFlow Delta Pro has been flying off the shelves due to its incredible performance, capacity, and longevity.
So, what’s the secret? Well, it all lies in their LFP batteries. Let’s talk about that.
The EcoFlow Delta Pro uses a lithium-iron-phosphate (LFP) battery that allows for up to 1600W of input at a time just from solar panels. This means that you can fully charge your 3,600Wh EcoFlow battery in just over 2 hours using only solar panels, which was unheard of prior to the launch of the Delta Pro.
For output, the Delta Pro can handle 3,600 continuous watts at a time and up to a 7,200W surge. Once again, this is uncharted territory, as many solar batteries can’t handle a small hair dryer for a couple of minutes at a time.
Okay, but don’t batteries burn out quickly? Not this one. The EcoFlow Delta Pro is set for over 6,500 lifecycles, meaning it can last for over ten years of heavy, daily use.
Even then, it should only drop by around 20% of its original capacity. Compare that to others that only last for 500 to 800 lifecycles and you’ll see that this model pays for itself. For more information on the system, feel free to read our full Delta Pro review.
Even many battery novices know that lithium batteries are the best and most efficient for energy storage. Compared to lead-acid batteries, nickel-cadmium, alkaline, and other common battery technologies, lithium batteries:
That’s the case foralllithium-based batteries, but LFP batteries take these a step further.LFP batteries operate similarly to other lithium-ion batteries, as they move between positive and negative electrodes to charge and discharge. However, the advantage phosphate is a non-toxic material compared to cobalt oxide or manganese oxide.
The average lithium-ion battery, not just LFP, lasts twice as long as a comparable Alkaline battery, and four times as long as nickel-metal hydride (NiMH) batteries according to Energizer. They can also be stored in a much wider temperature range and weigh less on average for similar output than either type of battery.
It’s clear that lithium-ion batteries are superior in every way you can name. However, LFP batteries tend to outlast LTO and other common lithium-ion batteries by up to 25%, making them the superior choice along with Lithium-Manganese (LMO) batteries.
The demand for batteries is surging (pardon the pun) and is expected to grow by at least 15 times by 2030. Well, that not only creates a demand formore batteries but also forbetterbatteries.
As we transition our energy grid away from fossil fuels, we will need to rely more heavily on battery technology for our grid, vehicles, and more. At a global level, this means using batteries to store energy from solar, wind, hydro, and nuclear power to be used during peak demand. At the consumer level, this will be in the form of home solar batteries, electric vehicles, and portable power stations for off-grid living, recreation, and home backup.
With this significant increase in demand and such a short time period, the cost of high-quality lithium-ion batteries, especially LFP batteries, will likely rise sharply in the coming years. If you want to get ahead of the curve, we suggest buying your own as soon as possible!
