GOLDENMATE 12V 10Ah LiFePO4 Lithium Battery(2 Packs), 5000+ Deep Cycles, Lithium Iron Phosphate Battery, Built-in BMS, Ideal for Power Wheels, Solar, Marine, Fish Finder, Ride-on Toy

Have a Cyberpower UPS with Seal batteries. Got an error code E02 which means filed to charge. Could be unit or batteries. I got these Lithium 10ah. Comparison. Seal bats were 12.9v at 9ah, and Lithin in 12.8v at 10ah. Once I tested UPS the old batteres were in fact no charging. Replaced with these higher end batteries and it was a flawless install. Perfect size and easy fit. The batteries were 99% charged and y the time I was done it went to 100%. I had orginally 396 minutes run time with a 1.5% load. Main used for my main finber and satelite internet. When I got this installed, it went to 420 minutes of run time. I have another unit and tested with that 1.5% load. Unplugged the unit and waited 10 minutes and it dropped from 396 to 379 minutes. On the new setup same test went from 420 to 416 in 10 minutes. WOW! In the end the new battereies worked perfect and I should do all mine UPS units this way, something to think about. I could have replaced the unit at $259 or get these at $63. I have been sold on the idea many years ago to use a UPS on everything you need power to when you have an outtage or like me or live in a rural area with contant drops or spikes, then a UPS is a must. Hope this helps some of you. I will start to place my batteries now before the actual units go back. And the fact they hodl a better charge is a win! Oh and old batteries will recharge at 2.7 amp max where these new one will 5am max. So faster recharge time when they do drain.

Came fully charged and install was fairly easy

Awesome product, holds life very well for the application I’m using it for

Have been replacing all my SLA batteries out of my various APC and Cyberpower UPS's as they naturally fail. The equivalent volume nets me more capacity so more runtime when I lose power. More importantly, they haven't failed as quickly as SLA's have in the past.

I’ve been using the GOLDENMATE 12V 10Ah LiFePO4 batteries for a few weeks now, and overall I’m really pleased with their performance. They feel well-made and lightweight compared to traditional lead-acid batteries, which makes them much easier to install and move around. I’m currently using them for a small solar setup and they hold a charge very well. Even though they are a little small in size for where i needed them to go, they are still doing the job. The built-in BMS gives some peace of mind by protecting against overcharging and short circuits, and the batteries seem to charge quickly and deliver consistent power. I also like that they’re rated for thousands of deep cycles, which should make them a great long-term investment. The only reason I’m giving 4 stars instead of 5 is that the included instructions could be a bit clearer for beginners. Once set up, though, they work exactly as expected. Overall, these are solid, dependable lithium batteries that work great for solar systems, ride-on toys, fish finders, and other small power applications. I’d definitely recommend them if you’re looking to upgrade from standard batteries.
