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

These fit in my APC 1500va UPS with a little work. Sisters backup the mismatched batteries I just swapped in it were showing the battery fault X even though it also shows full charge so I ordered these bigger capacity 10ah Lipo batteries to replace them. I had to modify the rack they use to stack the original sealed lead acid batteries because the lug spacing was closer together or they would have fit perfectly. As you can see no errors and fully charged with a small load from her pc and the cable modem and wifi routers. These were fully charged out of the box and run a slightly higher voltage than the original batteries. They showed 26 volts at the feed that goes into the ups just before I slid them in place and gave it a quick test. If you are using them with other gear the installation is probably super easy as they should pop right in place and hook up the power leads. They should run longer than the originals do too and should fit without any mods in most equipment. Price is fair for what you get and they are lighter and should last a lot longer before wearing out. As long as you aren't running a constant full load the BMS protection on the batteries shouldn't kick in either. So far I'm happy with them and would recommend them.

Great product holds charge for my fish finder for multiple days! Would buy again.

I've been using it for some time now, and there are no problems. It is much lighter than previous lead-acid batteries, convenient to carry, and charges quite fast, making it fully sufficient for daily use.

These batteries have performed exceptionally well thus far, and their long-term durability will be assessed over time. We are pleased with their performance to date, especially considering their competitive pricing.

You have to soder the battery's into a razor 350 other then that. They work great. It's like a brand new bike again. And now that I've done it'll be easy. Battery's are great they charge just as expected. They should come with small shrink seals to keep water out.

So far these Lithium batteries have been outstanding in my UPS. They have lasted longer than the lead batteries I’ve used the past.

They are working with solar charging however it is summer in Montana. Waiting for other cooler weather to see how they do.

Nice quality. Would buy again.
