SFK 275EX, space efficient and feature packed LiFePO4 battery

At first glance, the SFK 275EX looks like many other 275-300 amp hour internal BMS lithium iron phosphate batteries. With Bluetooth communications, heating, long cycle life, and a good warranty it seems to compete well with other batteries. But, closer inspection reveals a battery with features above and beyond anything I’ve seen in similar form-factor and priced batteries. Not only that, it comes with a thorough and readable manual.

My test bench runneth over with lithium from SFK, Mastervolt, and Epoch

I have big things planned for upcoming battery tests. I’m working to evolve my testing of LiFePO4 batteries to match their evolution. Battery capacities are increasing, physical size is decreasing, prices are dropping rapidly, and acceptance is increasing. New options hit the market regularly and keeping up with the pace of change can be challenging. In the coming months, I will review quite a few batteries in different positions in the market and try to help readers decide which price point and battery is right for them.

Update: Epoch’s 460ah battery, what we’ve learned

In January of this year, I published my review of the Epoch 460 amp-hour, 12 volt battery. My review was quite positive and reflected how the battery performed in my testing. But, once the battery was in the wild, reports began trickling in of troubles with some installations of the 460s. That lead to weeks of investigating the issues. At this point, I believe I have a solid command of what’s happening with these batteries and some of their limitations. While this better understanding of the batteries does serve to take a little shine off them, I still believe these are very solid batteries and capable of delivering excellent service. But, for best service, some tuning is required.

Li Time LiFePO4, no frills, serious value

My recent reviews of LiFePO4 batteries have focused on fully featured batteries with heating, Bluetooth, and CANBus communications, and even supercapacitors for engine starting. This time, I’m focusing on a battery that delivers raw value and no frills. Li Time batteries are all about delivering maximum energy storage for the smallest price. Although their batteries may lack the features of fancier batteries, they deliver the most amp hours for the fewest dollars. But how do they perform? Let’s find out.

Epoch Batteries, elegant drop-in LiFePO4

Good design matters, even for a product you probably won’t spend much time admiring. Epoch batteries’ line of LiFePO4 has design covered and an attractive list of features. But the big question is, are these batteries more than just a pretty face? I’ve been putting a couple of their 100 amp-hour, 12-volt batteries to the test, and it sure looks like they have the goods to back up the design.

Mercury’s 48-volt alternator and Fathom e-Power, state-of-the-art boat power?

An engine launch event might be an odd fit for an electronics and technology blog. I’ve attended Mercury launch events before, and each time, there’s been plenty of technology news. But when I went, I wasn’t expecting an announcement that could change the industry. I certainly didn’t anticipate the thunder from the launch of a 350 or 400-horsepower, 10-cylinder engine would be stolen by an alternator.

DIY LiFePO4 battery goes to work

ation for it. Once I finished the battery I knew I wanted to test it in a real-world scenario, but also one where troubles wouldn’t knock the house system of my boats or RV offline. Well, I think I’ve found the perfect place to get that real-world usage testing while also being able to tolerate trouble.

Discover Battery’s Lithium Blue LiFePO4, a premium drop-in

Discover Battery has been in the battery business since 1949, so they’re not new to the challenges of building batteries. They’ve recently begun distributing their Lithium Blue LiFePO4 battery in the U.S. and I’d say their experience shows in the quality of the product they’re delivering. Let’s take a look at what these batteries offer and how they’re different from what’s already available.

Victron RV upgrade, MultiPlus inverter especially

My family and I are getting ready to escape the Florida summer heat and visit friends and family we haven’t seen in much too long. Our trip’s mix of stops means sporadic availability of shore power, and that makes for great testing opportunities. I’ve been planning to install my DIY LiFePO4 battery to get some real-world testing in. But, to test any LiFePO4 battery, I needed to ensure the inverter and charger systems would coexist nicely with lithium chemistries.
