The Top LiFePO4 Brands to Choose From

At the moment, LiFePO4 batteries are relatively new, and as such, not every battery supplier has jumped on the bandwagon and started making them.

However, out of the suppliers that have started producing them, a few stand out as great options for various reasons.

We’re going to start with our top pick, and then we’ll go over a few honorable mentions.

1: MANLY’s Best LiFePO4 12v 200ah Battery

This is our top recommendation, and for practically anything you’d want to use a 12v battery for, it’s going to be the best you can get.

MANLY has several traits working to its advantage.

First, there’s the 200ah rating. The vast majority of 12v batteries max out at 100ah. This allows the MANLY battery to discharge 200 amps of electricity for an hour before the battery depletes. It’s unlikely that most devices will need that, but it more or less equates to more capacity overall and better flexibility.

However, that’s not the only thing that sets the MANLY battery apart. It has several features and traits that make it the best LiFePO4 battery at 12v 200ah.

First, there’s the built-in safety features. MANLY packs its batteries with overcurrent protection, undercurrent protection, short circuit protection, and temperature-based protection to ensure that you get the safest battery possible. Along with LiFePO4’s innate high level of safety, these safety features basically eliminate any concerns for fire hazards or unnatural battery failures; along with any concerns for poor current control damaging the items they’re hooked up to.

Then, there’s the advanced performance. MANLY batteries maintain their performance and capacity at 90% throughout their lifespan. They also charge a lot faster than the competition, and they provide reliable performance for roughly 8000 charging cycles before it’s recommended to replace them. This means that, even if the MANLY isn’t the cheapest up front, it’s still the best value in the long haul.

In terms of the battery itself, the final main benefit is that MANLY provides customized battery options to suit any need. So, if the off-the-shelf battery isn’t exactly what you need, you can place a custom order.

The battery supplier itself also offers a top-tier guarantee, 24/7 service, and a long-standing reputation across the entire planet. You can’t underestimate the value of great after-purchase care and customer support; especially given the demanding applications these batteries are used for.

2: SOK 12v 206ah Solar Storage

The SOK boasts many of the same specs as the MANLY, but it’s not as advanced with its safety features and focuses primarily on providing a stable battery for residential solar power storage. In short, it’s a great battery if you have at-home solar panels to offset your energy bill or keep your home powered during emergencies.

The casing also boasts a significant level of quality. SOK knows that residential homes are often prone to experiencing mishaps and issues. So, there’s extra care taken to make sure the battery is solid. You don’t have to worry about your kids banging on it, the dog ripping it out of its space, or anything else that can cause dangerous situations to occur.

However, the battery only features a limited 5-year warranty, and it’s priced above our top pick with less flexibility.

3: Lion UT 1300

The Lion UT 1300 boasts an incredible ampere, but it has a more limited battery as well.

With 1300ah, a lightweight design, and a smaller profile than expected, the Lion UT 1300 is a great option for on-the-go charging; whether you’re off-grid and need to power your comms, or you’re just at a worksite all day and need to keep your phone and smaller tools charged.

This is where the UT 1300 excels; as a personal charger for smaller electronics.

This is both a great design choice and a drawback.

Sure, you can use this as an amazing power bank for personal electronics, but if you want to operate complex items with it, such as powering your fridge during a power outage or running shop tools without having your shop attached to the grid, it’s not going to work.

It is priced appropriately, though. So, this is something that works great if you’re going camping for the weekend, work long hours, and need to charge your electronics, or something like that.

4: Battleborn 100ah Residential Solar Battery

This is another highly specific battery. It doesn’t try to get everything right for every situation, but it does try to be the best for residential solar power needs, and it does a great job.

The Battleborn 100ah is a LiFePO4 battery that has the standard 100ah rating, and it’s entirely designed around storing solar power and using it efficiently to power a home. That is great if you’re going to use it for a solar power system, but it produces several faults when you try to use it for other uses. Notably, its 100ah rating means that it can only use 100 amps in an hour, or it’ll deplete its entire charge.

However, it does provide 10,000 watts of power per charge, and that can help you keep the lights on, the fridge running, and your phone charged during a power outage. You just don’t want to try to run your entire house the same way you would if the grid were working properly.
