Best 12V Lithium Iron Phosphate Batteries of 2026

"I needed a battery for my Marcum LX9 and this one fit perfectly. Half the weight of lead-acid, and my fish finder runs flawlessly even after a full day out. The price was right and shipping was fast."

"I've been using this battery to power my solar driveway gate, and it's been consistently solid and dependable. The quality definitely stands out compared to others I've tried."

"I use this battery in my travel bag for my Xeigu G-90 ham radio, and it powers my 20-watt rig for hours—plus, it's lightweight and easy to hook up. For a fraction of the cost of pricier brands, it's a fantastic deal for Parks-on-the-Air."

"I’ve used this battery a handful of times, and I’ve noticed the voltage drops unexpectedly below 9 volts at random intervals, causing issues with my ham radio. After a minute or so, the voltage returns to normal, but this happens repeatedly, even after a full charge and only light use. I have other brands that have lasted hundreds of cycles without any trouble, so I’m disappointed in this one’s reliability."

"I bought two 12V 8AH batteries for my daughter’s power wheels, but only one would recharge after the first use. I tried contacting the manufacturer for a replacement but couldn’t reach them due to Amazon fulfillment. This leaves me with only one working battery and doubts about its longevity. I wish there was a better way to resolve defective product issues."

"I use this battery for different projects like solar lighting because it’s lightweight and compact, which makes it really versatile. It’s handy to have around for DIY setups and doesn’t take up much space."

"When my old lead-acid UPS battery failed, I replaced it with this LiFePO4 model. It charged up quickly and was running in under three hours. I noticed it's much lighter than the original, and the F2 terminals fit my UPS perfectly. I'm optimistic about the long lifespan, and overall, I think this is an excellent UPS battery replacement."

"I installed this battery in my gate opener and, after more than a month and a half, it’s outperforming my previous sealed lead-acid battery. Its lightweight build surprised me, yet it still delivers strong, reliable power. Definitely impressed for the price."

"I ran a capacity test on the battery I bought, which was supposed to be rated at 8Ah/100Wh. To my surprise, it actually delivered 9.2Ah/111Wh, exceeding expectations. The battery holds a charge well and is solidly built. If you want reliable, long-lasting power at a great value, I highly recommend this battery."

"I use this battery to power my diesel heater with my solar setup, and its outstanding performance really impressed me. It holds a charge perfectly, even on cold nights, and the built-in BMS makes me feel secure about safety and overcharge protection. The long lifespan and deep cycle ability give me peace of mind, and I appreciate how lightweight and acid-free it is for use anywhere."

"After replacing my old lead-acid battery with this one, I noticed it’s much lighter and lasts longer. It was a drop-in replacement and works far better than my previous battery. I’m really happy with this purchase."

"I installed this battery in a waterproof box for my trail camera, replacing 8 alkaline batteries. The compact size fits perfectly, and after two weeks of use, including some live streaming, it only dropped .02 volts. The battery provides plenty of power and is easy to mount."

"I replaced the batteries in my old scooter with these and was amazed at how much lighter the battery pack became. Installation was a breeze, and after a quick charge, my scooter—unused for years—was running again. The performance has been excellent, and it still works with the original charger."

"After using this lithium battery for six fishing trips, I can say it holds a charge for hours and powers my fish finder perfectly. It's lightweight and reliable, making it highly recommended for anyone needing dependable portable power."

"I've had these batteries in my UPS units for about three years. Most have worked well, and when I had an issue, the seller replaced them quickly and without hassle. In my experience, they perform best in digitally controlled UPS units, and I'm confident they'll last a long time when used correctly."

"I use this battery with my Yaesu FT-991A for SSB and FT8 operations, and after transmitting at high power for six hours, I still had about 25% charge left. It's very convenient with all the different connectors and is easy to carry. Great value, especially when on sale, and it feels sturdier than other 20Ah batteries I've tried."

"For my Parks on the Air activations with the FT-891, this battery gives me a solid 3-4 hours of 100 watt operation before the voltage drops. Compact size and fast charging make it super practical. The build quality and color are a bonus, and it's easy to move around."

"I switched to this battery for my kayak trolling motor after getting tired of lugging around a heavy lead-acid one. The light weight lets me carry it in a backpack, and I can cruise at full speed for 40 minutes and still have 50% charge left. I plan to buy another and still be lighter than my old setup."

"I noticed the high performance and long lifespan of this lithium battery right away. It's lightweight, charges fast, and holds power well. While the starting price is a bit higher, the overall value and convenience have made it totally worth it for my devices."

"I use this battery for my trolling motor, and I'm impressed with how long it lasts—even after a full day of fishing, I only use around 70-75% of the charge. It's a bit bigger than I wanted, but that's not a dealbreaker for me."

"I bought three of these for my 36-volt golf cart, hooking them up in series. The weight reduction made my cart faster, and the power output is perfect. This cost me much less than a big golf cart battery, and I'm very satisfied with my choice."

"I used this battery in my portable solar power station, and it's both lightweight and compact, arriving fully charged and ready to go. The included plastic terminal covers were a thoughtful touch. So far, performance has been flawless in my initial hours of use, and I'll definitely consider Goldenmate for any larger projects in the future."

"After years of dealing with heavy AGM batteries for my off-grid camera and lighting setup, I switched to a pair of these 20aH LiPo batteries. Charging is a breeze with my solar panel, and for the first time, my devices stayed powered all night. The weight savings are significant, and I’m hoping the batteries live up to their 5,000+ cycle claim."

"I bought three of these batteries for my mobile DJ truck to use as backup power for my wireless speakers. Building my own setup cost a third of buying replacements, and these batteries last longer. Even after two hours at full volume, the battery meter barely moved. The casing feels a bit delicate, but as long as you're careful with the terminals, you'll be fine. These have been a game changer for my gigs!"

"I was really impressed by how long this battery lasts and how easy it was to connect for backup power during outages. I use it with a converter to keep my devices charged, and the whole setup is extremely practical and reliable. I completely recommend it."

"Upgrading to this battery from my old lead acid was a huge improvement for my teardrop trailer. Its compact size and high capacity let me camp for several nights without worrying about power, and the handles make it easy to move around. I love that I no longer have to chase the sun for my solar panels all the time, and the value for the price really can’t be beat."

"I use these batteries in my solar setup for my camper, and they've performed flawlessly. I was especially impressed by the build quality—the connections and internal padding are far better than what I've seen in other budget batteries. Even though one arrived DOA (which was replaced), I would definitely buy from this brand again."
