Deep cycle Lithium Iron Phosphate (LiFePO4) batteries are a great alternative to power stations because, for the most part, they cost less in terms of the capacity you’re getting. You’ll still be spending less, even adding on the cost of an inverter and a battery charger. There are also ways to use these types of deep-cycle batteries without an inverter and have a direct connection to what you want to power.

I‘m looking at this Redodo 12V 100Ah LiFePO4 battery in this review. This comes from a well-known brand on Amazon, and their batteries are on the lower price side. I have done a full video review of this battery, but if you want to read a review article and take a look at photos, this one is for you.

What comes in the Box

What you’re getting in the box with this Redodo 12V 100Ah battery are four post bolts, two positive and negative insulated covers, a manual, and a piece of paper that gives you some info about the dos and don’t for the battery. You do not get a battery charger in the box and have to purchase that separately, and that’s not a problem in this case because, in general, batteries like this don’t come with battery chargers in the first place.

Overall, what you’re getting with this Redodo battery is standard for these batteries, and it’s not missing anything vital. Including four post bolts is a great addition; the manual contains rich information, and the paper giving vital info is a nice touch.

Power Capacity

So to get the Watt Hour (Wh) capacity of this Redodo battery, you have to multiply 12V and 100Ah, and you end up with a 1280Wh capacity. So, yes, this Redodo battery does have a 1280Wh capacity, and that’s a lot of power; when you consider a power station with a 1280Wh capacity, you’re looking to spend about $1,000 or more, in this case, you’re spending way less. Go ahead and look at their product page for this battery to see how little you’d pay to get so much capacity.

Of course, with a power station, you get everything already put together and ready to use. Still, as I mentioned, you can choose your inverter and battery charger when you go with a battery like this, which is very low cost. Also, this is a LiFePO4 battery, which can last for about 4,000+ charge cycles. LiFePO4 batteries are the way to go because you’re getting your money’s worth, as the battery will last much longer than Lead Acid batteries or regular Lithium-Ion batteries. You’re looking at many years of usage for this Redodo battery.

Also, when it comes to powering appliances for a 1280Wh capacity, you can power a 1W appliance for 1,280 hours or a 1280W appliance for 1 hour. So you have a lot more flexibility when it comes to the longevity of the capacity depending on what appliances you’re looking to power.

MakerHawk Battery Capacity Test

For the capacity test, I used a MakerHawk load test and connected the positive and negative clamps of the load test to the Redodo battery. I set the Voltage to about 12.8V and had the Amps set to about 10 Amps. I ran this test overnight to drain the capacity of this Redodo battery to 0%. After about 9 hours, I returned to the load tester turned off, and the battery was fully depleted of its capacity. What I ended up with was a 103Ah capacity and a 1,298Wh capacity. So on the Amp Hour (Ah) reading, I got a 103% efficiency rating, and on the Watt Hour (Wh) side, I got 101% efficiency. So this Redodo 100Ah battery has a 1280Wh capacity and a bit more, so you’re spending your money wisely for not only the capacity but also the many change cycles that come with a LiFePO4 type of battery.

Also, somebody mentioned in one of my battery capacity test videos that these batteries have a bit more capacity than they say they do to ensure they output the advertised capacity.

Output Charging:

Since this battery has a 1280Wh capacity, it has a 1280W continuous power output and a 1280W max input.

For our testing of this Redodo 100Ah battery, I used a Renogy 2000W Pure Sine Wave inverter. To clarify, you don’t have to use a 2000W inverter for this Redodo battery; in fact, using this inverter is way over the top. Instead, I would recommend a 1200W inverter or lower, depending on your budget and needs; however, in this case, I wanted to push this Redodo battery as far as possible to see what it is capable of. Also, when choosing an inverter, make sure that it’s a Pure Sine Wave inverter to ensure that your appliances run the way they’re supposed to.

Heater Test

So for the first test, I did with this battery through the inverter powering a Lasko heater. I had an electricity monitor connected to the inverter to tell me what was happening regarding Watt Hour (Wh) pulled from the battery and the wattage output the appliance was drawing. I set the Lasko heater to low first and ended up with an 850W output; this is not a problem for the Redodo battery to handle as it’s capable of a 1280W continuous power output. After running it at low for about a minute, I set the heater to high, and the output jumped to about 1400W. With a 1400W output, the heater is over the 1280W output of this Redodo battery, but it still keeps running.

I kept running the Lasko heater for 47 minutes until the battery was completely depleted. So you can run a 1400W load from an inverter using this Redodo battery, and it can handle it for nearly an hour. Also, I got an AC capacity of 1,100Wh, which is a 86% efficiency rating when it comes to using an inverter with the battery; this type of conversion through an AC outlet is better than most power stations.

Electric Cooktop & Toaster Oven Test

For the next test, I used a 1000W electric cooktop and placed a saucepan with four cups of water on top to see how fast I could boil water and how much capacity I use up. The cooktop pulled about 950W; it took about 8 minutes for the water to boil and used up 120Wh of the Redodo battery’s capacity. So you can easily cook with a high enough wattage inverter using this battery, and you won’t lose much capacity.

For the final test, I used a toaster oven to power from this battery and inverter. I set the toaster oven to 450° F and had to run it for about 10 minutes. The toaster oven pulled 1170W and used about 120Wh capacity from this Redodo battery. So you can easily have food toasted with this battery, too.

Overall, a 12V/100Ah battery is best to own. Going lower on the Amp Hour (Ah) scale means having lower wattage usage and less capacity to use, which ultimately means a shorter runtime. Going with a higher capacity battery means spending more, but at the same time, you get so much more capacity and wattage usage. That said, 100Ah batteries are the sweet spot for price and function.

Recharging the Battery:

You can use any 14.4V or 14.6V battery charger to recharge this Redodo 100Ah battery. In my case, I used an Ampere Time 10 Amp battery charger to recharge the unit. This is one of the lowest-cost battery chargers you can get, but it’s also one of the slowest ways to recharge. This Ampere Time 10 Amp battery charger works the same way as any other one. I just attached the negative and positive clamps to the negative and positive terminals on this Redodo battery, and it began charging.

The light on the Ampere Time battery charger turns red to indicate that it’s charging, and then it turns green to indicate that the battery is fully recharged and charging stops. Of course, as I mentioned before, a 10 Amp battery charger is relatively slow, and going from 0% to 100% will take about 10 – 12 hours.

Size and Weight:

This Redodo 100Ah battery has a length of 13 inches, a width of 6.7 inches, and a height of 8.4 inches. The battery weighs 25 pounds. So it’s not a large battery, but it has some weight. The battery does have a handle strap that makes it easier to move around, and you can also easily remove the handle if you want.

Functional Components:

In this case, when it came to using the battery with the Renogy 2000W inverter, I connected the negative and positive terminal cables from the inverter to the battery. Once the terminal ends were screwed onto the battery, I could turn on the inverter and power the appliances.

Build

Structure and Material:

The build quality of this Redodo battery is good. The battery has an IP65 water resistance rating, meaning it can withstand rain and high-pressure jets but cannot withstand water submersion. The casing is solid, and I couldn’t find any flaws with its build quality. However, you shouldn’t drop this battery, as I’m not sure if the casing can survive a fall, as most batteries are not exactly built up to that standard.

Tech:

For the technical build, this Redodo battery has overcharge, over-discharge, temperature, short circuit, and all other protections to ensure that it performs smoothly and that you’re safe. In my heater test, when I had the heater running at about 1400W, this battery could keep supplying power to the Renogy inverter. If the battery got too hot, it would automatically shut off, but that didn’t happen in my test, as it could fully deplete its capacity.

Reliability

The testing I’ve conducted from the MakerHawk load tester and the Renogy inverter shows that this Redodo 100Ah battery is very reliable. It has the capacity it says it has a little more. Also, it uses a LiFePO4 battery cell which gives many charge cycles that allow the battery to last for many years. On the inverter side, I could power a Lasko heater at 1400W, above the 1280W that this battery is capable of. The inverter AC capacity pulled 86% efficiency from this Redodo battery.

So, this is very reliable for a 100Ah LiFePO4 battery.

Summary:

Power:

This 1280Wh capacity is precisely what you’re getting, and just a bit more because of the load test I ran. This battery can also handle loads over its 1280W max continuous output, as I ran a 1400W load for nearly an hour.

Design:

This battery is pretty small, but it does weigh 25 pounds. The removable handle does make it easier to carry the battery. Connecting the inverter was very easy, and recharging was simple, too.

Build:

The build quality of this Redodo battery is solid because of its IP65 water resistance rating. It also has many technical protections that ensure it will be safe, such as overload, short circuit, and temperature control protections.

Reliability:

If you want an all-around reliable battery, a 100Ah battery is the one to go with, as it has tons of capacity, power input, and output capabilities, and it comes at an affordable price compared to a 1280Wh power station.
