GOLDENMATE 12V 10Ah LiFePO4 Lithium Battery(2 Packs), 5000+ Deep Cycles, IP67 Waterproof Lithium Iron Phosphate Battery, Built-in BMS, Ideal for Power Wheels, Solar, Marine, Fish Finder, Ride-on Toy

these were perfect replacements for my sons razor mx350! Definitely last longer than the originals, charge faster, and top speed slightly improved.

Working great, strong power and long run time on a charge. I use in a trailer tugger dolly and move up to 22’ tandem car haulers and the batteries have all the power needed and has moved more than 2 dozen trailers before losing 1 dash on the charge indicator.

Perfect replacement for my son's Razor Dune Buggy. Light weight, exact fitment on the battery tray. Seem like a pretty solid battery from the feel.

I purchased a few of the Goldenmate UPS systems over a year ago, and they have been working well, even during a couple of power outages. I decided to pickup the 10Ah batteries, one for my security system battery backup (works well and does charge), and I tried one in an old Tripp-lite UPS system. Even though it isn't a lead-acid battery it does work in the Tripp-lite. It seems to take a bit longer to charge, but it does go to full charge and does work as a UPS. Happy with the purchase.

Fits and works just fine in my APC UPS, and made it a heck of a lot lighter, too!

Very good replacement for my gate opener battery's that barely lasted a year. Seems to hold a charge longer than the other ones.

The 10ah batteries are the exact same size as the 9ah batteries that fit in the Panamax (Furman) MB1500 unit so you get a few extra precious minutes of power. The four batteries replaced a set of completely dead batteries that kept setting off the alarm and give 99 minutes of backup power in total. With these you also move away from lead acid to a more modern, efficient power source material.

I used 3 of these as direct swaps for the SLA 12v/10ah. Except it's not direct. These are not as tall. I had to design and 3d print a spacer to help keep the batteries nice and snug. The power difference is hilarious as is the longevity. I only have to recharge after mowing three times. The best part is how light the battery pack is now. You can one hand the thing, I'll put the spacer on printables. The original B&D 36V mower
