Excellent mini battery. I used two of these in a portable solar generator. They were much lighter than standard batteries and smaller than the usual Lithium. Because of their size, I was able to use two, instead of the normal one in this project. They charge fast and I was able to get them balanced with no issue by charging one completely then the other before hooking them up.

⭐⭐⭐⭐⭐ Absolutely impressed with the Elefast LiFePO4 battery! From the moment I unboxed it, I could tell this is a high-quality, well-built power source. The sturdy design, clear terminals, and convenient carrying handle make it super user-friendly. Performance-wise, it delivers reliable, long-lasting power — perfect for my energy needs. The battery holds charge exceptionally well and charges efficiently too. If you’re looking for durability, performance, and peace of mind, Elefast is the brand to trust. Highly recommended!

I bought 2 of these and I am really happy with the quality and performance. I plan to purchase more... great value for money.

I bought the 200ah Lithium battery. Took it out on the lake and fished trolling slowly for approximately 2 hours. It only went down to 192 ah! I love the BMS (Battery management system). I didn't even know this was a thing but what a great way to see the actual level of the battery and even each individual cell. And of course it is so light at just 45# compared to at least 90# for the same SLA battery at 200ah. I hope this lasts me for years.

So far I've been very happy with the functionality of this battery. I use it to add capacity to my Delta 2 Portable Power Station. I also have the 12v 100AH from the same company and it's working well too.

This is a great battery. Definitely planning on purchasing a few more for my off ride setup. Great price. Light in weight compared to lead acid. East to install and it fits great with its smaller size. Bee. Happy so far.

I purchased this battery march 21 2025 I at the most get to use it 1 day a weekend for a couple hours on August 16 I had just started a path with my trolling motor at 0.5 mph and it just quit shortly after we started. After tearing my trolling motor half way down and couldnt find anything wrong with it. I went to checking the new battery. It would say fully charged but when I ohm'd it out it showed 20.8v on it I put the positive cable from my trolling motor without it on. It instantly showed 1.2v. I want a replacement or a refund and can’t figure out how to get in touch with anybody. It worked really good Until it didn’t

When I started in my solar journey I knew absolutely nothing about it. After doing some very extensive research, I found the LIFEPO4 Battery. I chose this specific brand because it was compatible with my system and had good reviews. After purchasing one we realized we had to have a minimum of two to even be able to use the solar, so this is my second purchase from the same company. They literally shipped both of my batteries the very next day and I received it within 5 days! It's about 17 pounds, easy to install packaged very well. I also had to email them to get numbers to input into my systems controller. I received a response within a few hours! All I know is I'm still a bit confused about the solar system but I was impressed with Lifepo4 and will now continue to purchase all of my batteries
