Whenever you’re purchasing for a transportable energy station, there are plenty of complicated numbers to determine—however crucial element to contemplate isn’t a quantity in any respect! It is what your battery is fabricated from.
It’s Battery Chemistry That Issues Most
I’ve bought a number of moveable energy stations for my residence. Some are sufficiently big to include over 3,800 watts of capability. That’s sufficient to maintain our fridge operating for over a day. Some are 1000 watts and higher sized to energy a scorching plate or a TV. Our 300Wh items are greatest for telephones and gaming handhelds.
What all of them have in widespread isn’t their measurement, however their battery chemistry. In different phrases, they’re all fabricated from the identical kind of battery—and it’s completely different from the sort you used to seek out beneath your automobile’s hood or inside most telephones.
They’re all lithium iron phosphate batteries, often known as LiFePO4 or LFP.

The Anker F3800 Plus is an up to date model of Anker’s F3800 photo voltaic generator, providing the identical 3.84kWh capability and 6000W output. This mannequin comes with improved charging, with a brand new max photo voltaic enter of 3200W and 165V, together with assist for 240V from a gasoline generator.
What Is LiFePO4?
LiFePO4 batteries, technically, are nonetheless lithium-ion batteries. The distinction is the battery chemistry. In distinction with the lithium cobalt oxide (LiCoO2) and nickel manganese cobalt (NMC) lithium batteries widespread to our moveable units, LiFePO4 batteries use lithium iron phosphate because the cathode (or detrimental aspect) and makes use of carbon because the anode (or optimistic aspect).
These batteries aren’t power dense, in order that they aren’t small, which is why you don’t see them inside smartphones. However they arrive with many benefits that make them superior for supplying backup energy.
LiFePO4 Batteries Have a Longer Lifespan
Batter chemistry determines what number of years of use chances are you’ll get out of any given battery. This data is usually indicated in two methods. One is the variety of cost cycles, which refers back to the variety of occasions you possibly can cost and discharge your battery earlier than it stops holding a cost as successfully. The opposite could be in years, with phrases comparable to “in 10 years, the battery will cost to 80% of its present capability.”
In some methods, that is two methods of claiming the identical factor. A battery that lasts 800 cost cycles can cost and discharge day-after-day for round three years earlier than it degrades. A battery that lasts 5000 cycles will nonetheless be going robust in a decade.
Whereas a non-LiFePO4 battery just like the Jackery Explorer 300 can go 500 cycles earlier than being diminished to 80% capability, the LiFePO4 Jackery Explorer 300 Plus can final for 3000 cycles earlier than seeing the identical discount in how a lot power it will possibly retailer. This is the reason LiFePO4 batteries additionally have a tendency to come back with longer warranties.
LiFePO4 Is Far Much less More likely to Catch Fireplace
Batteries are methods of storing excessive quantities of power in a small quantity of area. Whereas they’re not as simple to ignite as a tank of gasoline, they do nonetheless include the chance of fireside. When lithium-ion batteries catch fire or explode, it is often the results of short-circuiting, which might occur for varied causes.
When mishaps occur, lithium-ion batteries can expertise what’s often called thermal runway. This results in a hearth that’s self-generating till the battery totally discharges. This is the reason when some electrical vehicles catch hearth, firefighters concentrate on containing slightly than extinguishing the fireplace.
LiFePO4 batteries are many orders of magnitude safer than different kinds of lithium-ion batteries. Not solely are they unlikely to catch hearth, however they launch a lot much less power that even when they’re punctured, they’re extra more likely to launch smoke than flames. You’ll be able to see this in a drill take a look at that Will Prowse showcased on his YouTube Channel.
This is the reason most built-in residence backup batteries more and more use LiFePO4 batteries as an alternative of different battery chemistries.
LiFePO4 Can Be Saved at 100%
As talked about, most lithium-ion batteries don’t prefer to be totally charged. Whilst you can cost batteries to 100%, most favor to be at 80% or decrease (however not too low—they don’t like to take a seat round at beneath 20%, both). Which means that in the event you purchase a 1024Wh moveable energy station with lithium-ion batteries, it’s greatest saved with a capability of 819Wh. If the ability goes out unexpectedly, you don’t even have entry to as a lot energy as you may need anticipated when shopping for the unit.
A LiFePO4 battery may be saved at 100% simply positive. It is because the battery is constructed out of various supplies that reply in a different way when holding that many electrons.
As an alternative of shopping for a built-in residence battery, my spouse and I opted to spend less money on several portable power stations as an alternative. They’re all LiFePo4 batteries stacked in our pantry at round 90–100%. I wouldn’t really feel practically as comfy storing as many batteries fabricated from an older battery chemistry—a minimum of not one this huge. Nor would I spend this a lot cash on batteries that should be changed in just some years. However with LiFePO4, security and longevity have largely been addressed.
That is to not say these batteries are good. If nothing else, they’re costly, which is motive sufficient to control other emerging battery chemistries like sodium-ion. But till then, LiFePO4 is the way in which to go.
