LiFePO4 batteries are often confused with Lithium Ion. In reality, LiFePO4 is a step up from lithium-ion, known as lithium iron sulfate. LiFePO4 incorporates iron sulfate for the positive side of the battery and graphite carbon for the negative side.
These batteries feature an improved energy density, even though they are technically lithium-ion themselves. If you’re looking for a LiFePO4 battery, the only differences you’ll run into are brands and how well these brands manufacture their LiFePO4s.
In general, all LiFePO4s should offer around 3,000 cycles and as many as 10,000 for the super-premium versions. “Cycles” refers to the number of discharges and charges a battery can take before it drops below 80% efficiency. With that being said, which LiFePO4s are worth a second look?
1. Digi Marker LiFePO4 Batteries
Features
- BMS protection from overload, over-discharge, overheating, short circuits, overcharge, and over-current
- High quality, M8 Terminals
- ABS Plastic casing
- Companion App
- 4-year warranty and 24-hour service included
Whether you need a battery for a four-wheeler or a deep cycle battery for running the electronics on your boat or RV, Digi Marker manufactures them all. In addition, they market their LiFePO4 batteries as entirely maintenance-free.
Digi Marker manufactures ten different batteries, and in ascending order, they run from 12.8v, 60Ah, and 768Wh small batteries to 12.8v, 300Ah, and 3840Wh batteries. With that many batteries, Digi Marker has you covered for every eventuality.
The additional four-year warranty is a nice touch as well. In addition, it’s 40% of the battery’s lifespan, which is a good deal more than many of the lithium-iron sulfate battery manufacturers out there.
The ABS plastic casing isn’t the best protective shell out there, but it’s pretty good. It will protect your battery from small impacts, water splashes, and corrosion so that you can use these batteries for a number of applications.
Another advantage of these batteries is that they support 4 series and 4 parallel, a must-have feature if you’re living off the grid or boondocking in an RV for an extended period of time. A series set-up with some solid solar panels can keep you juiced up for days, if not indefinitely.
