Iron Edison’s NEW Lithium Iron Battery: The 4LiFe

Iron Edison’s 4th generation Lithium Iron Phosphate battery is an exciting development in battery bank storage technology.

(Scroll down to read why I like them for preparedness)

It’s seemingly a perfect solution for new solar projects or upgrading existing solar systems to the benefits of Lithium.

If you have an aging lead acid battery system, this lithium battery may be a direct replacement. And the bonus is a lower cost of ownership over time than lead acid. (Yes, you heard that right)

Features | 4LiFe Lithium Iron Battery

The IronEdison4LiFe is a sealed maintenance free battery solution that can provide decades of reliable and worry free energy storage for your off grid or grid interactive energy system.

An integrated battery management system prevents damaging overcharging or over discharging.

Up to four batteries can be paralleled, creating a battery solution with over 61 kWh of capacity!

Safety | 4LiFe Lithium Iron Battery

Iron Edison uses Lithium Iron Phosphate for all of their Lithium batteries. It is the safest chemistry in the Lithium Ion family.

Unlike the lithium cobalt oxide battery chemistry found in consumer electronics that are known for thermal runaway and other safety concerns, Lithium Iron Phosphate is known as the safest lithium ion chemistry available.

This paired with their integrated fail safe battery management system eliminates the potential for any dangerous failures.

Battery Life | 4LiFe Lithium Iron Battery

The new 4LiFe has up to 40 years of life expectancy!

When you run a cost analysis, this means a levelized cost of ownership (LCOE) of only $0.12 / kWh!

Compare that with lead acid’s $0.25 to $0.80 / kWh, and you’ll see that this battery is an excellent investment choice.

A Best Choice For Battery Bank

Everyone has their own specific needs, requirements, and opinion.

I am currently running a lead acid battery bank in my alternative energy solar system (off-grid circuits into the home side-by-side with my grid utilities).

When it’s time to replace the batteries as they reach their end of life, I will most definitely be looking into Iron Edison’s new (4th generation) Lithium Iron battery.

Here’s a previous article that I wrote about their batteries:

Lithium Iron Battery for Off Grid

Why I like them for preparedness

There are several reasons why these batteries are appealing to me for preparedness.

  1. Their in-service life is much longer than lead-acid.
  2. 80% depth-of-discharge! Much more usable energy (amp hours).
  3. Smaller footprint compared with lead-acid.
  4. Maintenance free.

  1. So would these be suitable for a trolling motor?
    It’s actually part of my plan. In SHTF I can’t maintain a gas boat motor but I can a battery operated trolling motor on a bass buggy running trot lines and bow fishing.

    1. Matt, well, no. These are 48V batteries. 48 volts is the typical voltage for most off-grid battery bank systems (better efficiencies). Trolling motors are 12 volts.

        1. Matt, I’ve heard good things about Firefly Oasis Carbon Foam AGM Group 31 batteries. They are 12 volt and and designed for marine use. Not cheap but supposed to last 3 times longer than a typical AGM battery.

    1. The reference to 61 kWh is an example of the high capacity you could get (by paralleling 4 of their larger batteries).

      Their smallest size will hold just over 5 kWh of energy capacity.

      And it could be per day, per whenever. It’s a storage of energy until replenished or ‘filled back up’.

  2. Hmmmm… I wonder what a person might use in an RV? I have been thinking of setting up a 12v system (actually two batteries in parallel) with a simple solar charger on the roof. I guess the same question would apply to a boat. Open to suggestions.

    1. i have done that.. 2 x 12V batteries in parallel with a solar panel that trigger charges them, using
      a cheap solar charging regulator harborFreight to control the charging. Lasted us about 3 years until we sold the 5th wheel.
