What Is the Redodo 4 Pack 12V 100Ah Group 24 LiFePO4 Battery?

When we look at the Redodo 4 Pack 12V 100Ah Group 24 LiFePO4 Battery, we are looking at a full power system, not just a single battery. Four 12V 100Ah lithium batteries together form a flexible energy storage solution that can be wired for 12V, 24V, or 48V systems depending on how we configure them.

These batteries are designed specifically for deep-cycle use: RVs, vans, campers, boats, solar power storage, and off-grid applications. This means they are made to be discharged and recharged repeatedly without suffering the quick wear and tear we see in traditional lead-acid batteries.

This table distills the main technical details into something we can understand at a glance, so we can decide if this setup fits our use case.

Weight and Portability: 1/2 Lighter Than Lead-Acid

Why the Weight Difference Matters

One of the first things we notice if we are used to lead-acid batteries is how light these Redodo Group 24 LiFePO4 batteries are. At about 22.16 lbs each, they are roughly half the weight of a typical 12V 75Ah Group 24 lead-acid battery, which can easily weigh around 52 lbs.

In an RV, van, or small boat, weight is not just a comfort issue; it is a safety, fuel economy, and payload issue. Cutting battery weight in half allows us to redistribute weight for better balance, carry more gear, or simply make installations and changes much easier on our backs.

Easier Handling and Installations

Because each battery is so much lighter, lifting them into a battery compartment, mounting them in a van build, or swapping them out becomes realistic for one person. We do not need a second set of hands every time we want to reorganize the battery bay or adjust our setup.

For those of us who move batteries around seasonally—between a cabin and an RV, for example—this weight difference becomes a big quality-of-life improvement.

Capacity and Runtime: 2X the Running Time vs Traditional SLA

How 100Ah LiFePO4 Compares to 75Ah Lead-Acid

On paper, 100Ah vs 75Ah might not sound like double the runtime, but in practice it is very different because of usable capacity. With a standard lead-acid deep-cycle battery, we generally only use about 50% of the rated capacity if we want to protect the battery’s lifespan. That means a 75Ah lead-acid battery realistically gives us about 37–40Ah of usable energy.

By contrast, LiFePO4 can comfortably use around 80–90% of its rated capacity without significantly impacting the battery’s life. So with the Redodo 12V 100Ah LiFePO4 Battery, we might reasonably use 80–90Ah on a daily basis.

Why This Works Out to About Twice the Runtime

If we compare:

Typical usable capacity for 75Ah SLA at 60% discharge rate: around 45Ah
Usable capacity for 100Ah LiFePO4: around 80–90Ah

We can see that we are getting roughly double the actual usable energy out of the same physical footprint. In other words, if our fridge, lights, and devices used to last one night on a lead-acid battery, they might now last us two similar nights on the Redodo battery, assuming similar usage patterns.

When we multiply this by four batteries in the pack, that available runtime becomes substantial for off-grid stays and boondocking.

Battery Life and Cycle Count: Up to 8X More Life Cycles

What 4000–15000 Cycles Really Means

The manufacturer states that these batteries can provide between 4000 and 15000 cycles under recommended usage conditions. In contrast, a typical SLA (sealed lead-acid) deep-cycle battery often gives us around 500 cycles before its capacity begins to degrade significantly.

To visualize this:

Using an SLA battery daily: roughly 1.5 years until we notice noticeable degradation with 500 cycles
Using these Redodo LiFePO4 batteries daily: several years, potentially over a decade, depending on how deeply we discharge them each cycle

Even if we only ever reach 4000 cycles with normal use, that is still about 8 times the life expectancy of a lead-acid battery with 500 cycles.

Long-Term Cost Effectiveness

At first glance, LiFePO4 batteries cost more upfront. But if we spread that cost over 8 times the number of cycles, the long-term cost per usable cycle tends to be much lower than with SLA.

For us, this means fewer replacements, fewer trips to buy new batteries, and more trust that our system will still be performing well years down the line.

Built-In 100A BMS: Protection and Performance

What the 100A BMS Does for Us

Each Redodo 12V 100Ah Group 24 battery includes a built-in 100A Battery Management System (BMS). This is essentially the “brain” of the battery that:

Manages charging and discharging
Protects from overcharging
Prevents over-discharging
Guards against overcurrent
Cuts off in short-circuit events
Monitors high temperature and cuts off above 60°C/140°F

With a 100A maximum continuous charge/discharge rating, each battery can safely handle up to 1280W of continuous load (at around 12.8V). That is plenty for typical RV systems, fridges, lighting, inverters for smaller appliances, and DC loads.

Safety and Peace of Mind

We might not actively think about it, but a battery system is storing a lot of energy in a small space. The multiple protective functions of the BMS mean we are adding an extra layer of safety for ourselves, our family, and our vehicle or cabin.

If the battery encounters a situation outside safe parameters—such as extremely high temperature or a short circuit—the BMS cuts power to protect both the battery and the equipment hooked up to it. For an RV or van, this is extremely reassuring.

Temperature Ranges and Real-World Use

Operating Temperatures for Charging and Discharging

The Redodo Group 24 12V 100Ah LiFePO4 battery is rated for specific temperature ranges:

Charging: 0°C to 50°C (32°F to 122°F)
Discharging: -20°C to 60°C (-4°F to 140°F)
Storage: -10°C to 50°C (14°F to 122°F)

This means we can discharge (run our loads) in sub-freezing temps down to -4°F, but charging should not be done below freezing (32°F). This behavior is common for LiFePO4 chemistry.

What This Means for RVers and Off-Grid Users

If we camp in cold climates or keep our batteries in an unheated compartment, we need to be mindful about winter charging. Some users add battery warmers or keep the batteries in a more temperature-controlled area of the RV or van.

On the plus side, the wide discharge range allows us to run our lights and appliances even when temperatures drop, as long as we are not trying to charge the battery when it is below freezing.

Group 24 Size and Compatibility

Standardized Dimensions That Fit Existing Battery Boxes

The stated size of each Redodo Group 24 LiFePO4 battery is:

Length: 10.24 inches
Width: 6.61 inches
Height: 8.3 inches

These dimensions fit a standard Group 24 battery box. For many of us, that means we can remove an existing Group 24 lead-acid battery and drop in one of these batteries in the same space, often with minimal or no modification to the battery tray or box.

Ideal for RVs, Travel Trailers, and Motorhomes

The product is designed with RV applications in mind: travel trailers, Class A/B/C motorhomes, and similar platforms. Because it follows Group 24 specifications, it tends to comply with relevant sizing and installation regulations that RV manufacturers follow.

For van conversions, this size is quite flexible and can be mounted under seats, in cabinetry, inside battery boxes, or under beds as long as we account for ventilation and cable routing.

Safety Features: Five Layers of Protection

The Five Protections Built In

The Redodo 12V 100Ah Group 24 LiFePO4 battery includes five primary protection mechanisms:

Overcharging protection
Over-discharging protection
Overcurrent protection
Short-circuit protection
High-temperature cut-off

When the environment or usage hits a dangerous threshold—like a short or extreme temperature—the BMS disconnects to prevent catastrophic failure or damage.

Why This Matters in Confined Spaces

In RVs, vans, boats, and cabins, battery storage is often in tight or enclosed spaces. Fire or battery failure is not something any of us want to risk. These protections reduce the likelihood of damage or unsafe conditions and help us feel more confident about installing these batteries in living spaces.

LiFePO4 chemistry is also inherently more stable and less prone to thermal runaway than some other lithium chemistries, which adds another layer of security to our off-grid installations.

Where This Battery Shines: Common Use Cases

RV and Camper Power Systems

For RVers, this battery is built with us in mind. Four 100Ah batteries give us generous capacity for:

Running 12V fridges and lighting
Powering water pumps and fans
Running an inverter for laptops, small kitchen appliances, or entertainment
Supporting solar arrays for boondocking or off-grid camping

Because of the higher cycle life and deeper usable capacity, we can stay off hookups longer without worrying as much about draining or damaging our batteries.

Van Life and Custom Conversions

For van builds, the compact Group 24 form factor and low weight make it easier to integrate these batteries into tight spaces. Four batteries can be arranged in creative ways to fit into cabinetry or hidden compartments while still giving us serious energy storage.

We can wire the four batteries in a parallel 12V configuration for larger amp-hour capacity, or in series/parallel combinations for 24V or 48V systems when paired with compatible inverters and charge controllers.

Solar Power Storage and Off-Grid Cabins

If we are building a solar-based power system for a cabin, shed, or tiny home, these batteries offer a stable, long-lasting storage bank. Their long cycle life and deep discharge capability pair very well with solar charging, which tends to fluctuate based on sun availability.

We can create a robust off-grid system by pairing this 4-pack with an appropriately sized solar array, a quality MPPT charge controller, and an inverter that matches our voltage and power needs.

Trolling Motors and Marine Use (With Limits)

Suitable for 30–70 lbs Trolling Motors

The manufacturer specifies that this battery is suitable for use with trolling motors in the 30–70 lbs thrust range. In that range, the 12V 100Ah LiFePO4 capacity can provide hours of runtime, especially at moderate throttle settings.

The high cycle count also benefits us for frequent fishing trips; we can recharge after each outing without worrying that we are wearing out the battery as quickly as we would with SLA.

Not for Engine Starting or Golf Carts

It is important to note that this battery is not designed for starting engines or for use in golf carts. Starting batteries need a high burst of current in a short time, and golf carts often require high-current, sustained draws at specific voltages where special-purpose lithium packs or lead-acid sets are more common.

The Redodo Group 24 LiFePO4 is optimized as an energy storage and deep-cycle battery, not as a starter. We should keep it in that role to get the most out of it.

Charging Considerations and System Integration

Getting the Most Out of Charging

To get the best performance and lifespan out of these batteries, we want to use a lithium-compatible charger or a charger with a LiFePO4 setting. Proper bulk, absorption, and float stages that match LiFePO4 charging profiles help us maintain voltage and capacity over the long term.

If we use solar, we want an MPPT or PWM controller that supports LiFePO4. That way, we can dial in correct voltage limits and charge curves.

Mixing with Other Battery Types

We should not mix these LiFePO4 batteries with lead-acid or other chemistries in the same bank. Different charge/discharge characteristics can cause imbalance and reduced performance or lifespan. Ideally, our battery bank should be made up of identical batteries purchased around the same time.

If we use the 4-pack together, we should wire them in a balanced way—same cable lengths and secure connections—to ensure even charging and discharging across the entire bank.

Performance vs Traditional Lead-Acid: A Comparison

To better understand how these Redodo LiFePO4 batteries compare to typical Group 24 SLA batteries, we can look at a side-by-side summary.

Aspect	Redodo 12V 100Ah LiFePO4 (Group 24)	Typical 12V 75Ah SLA (Group 24)
Weight	~22.16 lbs	~52 lbs
Usable Capacity	~80–90Ah	~40–45Ah (at 60% discharge)
Cycle Life	4000–15000 cycles	~500 cycles
Maintenance	Maintenance-free, no off-gassing	Often maintenance-free (AGM), still heavier
Depth of Discharge	Safely deeper (80%+ regularly)	Usually limited to ~50% for best lifespan
Voltage Stability	Holds voltage well until near empty	Voltage sags as it discharges
Charging Efficiency	Higher (often 95%+)	Lower (around 70–85%)
Upfront Cost	Higher	Lower
Long-Term Cost/Cycle	Lower (spread over far more cycles)	Higher due to frequent replacements

This comparison illustrates how, while the initial purchase cost may be higher for LiFePO4, we are getting more usable energy, significantly longer lifespan, and a lighter, more efficient system overall.

Installation Tips and Best Practices

Planning the Battery Layout

With a 4-pack, we have multiple installation options:

All four in parallel for a large 12V bank (400Ah total nominal)
Two in series and two in series-parallel for a 24V or 48V system (with proper planning)

Before installing, we should:

Measure our battery compartment or planned location
Ensure ventilation and access for cables and fuses
Use an appropriate battery box or secure mounting solution
Plan cable routing with correct gauge wires for expected current

Wiring and Protection

We want to protect our system with:

Properly sized fuses or breakers near the battery positive terminal
Heavy-gauge cables sized for our maximum current and distance
Quality lugs that are crimped and, ideally, heat-shrink sealed
A main disconnect switch for safety and maintenance

Balanced wiring (equal-length cables to each battery) helps ensure that each battery in the 4-pack carries its fair share of load and charge, which supports better longevity.

Everyday User Experience: What It Feels Like to Use

Less Worry About Deep Discharge

With lead-acid batteries, many of us constantly watch the monitor, afraid to let the battery drop too far because of damage risk. With these LiFePO4 batteries, we have more flexibility. We can comfortably use a much larger portion of our capacity without that same sense of anxiety.

That translates into a more relaxed experience: we can run a fridge overnight, charge devices, keep our lights on, and still know the battery is not suffering the same stress as a lead-acid bank would.

Stable Voltage for Sensitive Electronics

LiFePO4 batteries hold their voltage more steadily throughout the discharge cycle. Sensitive electronics, such as laptops, routers, and inverters, generally perform better and more consistently when voltage is stable.

We tend to notice fewer “brown-out” style issues where things suddenly shut off due to sagging voltage, especially at higher loads.

Customer Support and Additional Information

Manufacturer Support

The product information indicates that the Redodo service team is available for further questions. For us, that support can be helpful when:

We are planning a more complex system (series/parallel configurations, higher voltages)
We want to confirm compatibility with certain chargers or inverters
We have questions about warranty terms or best charging practices

Having accessible support becomes important when we are making a long-term investment in an energy system.

Keeping Expectations Realistic

While these batteries are designed for long life and high cycle count, we still need to follow:

Recommended depth of discharge guidelines
Proper charging voltages and currents
Temperature limits for charging and storage

Doing so allows us to get closer to the advertised lifespan and ensure the pack serves us well for many years.
