  • Nice project battery
Size: 12V 30Ah
I used this in a portable solar power station project. So far it's working great. It's nice and compact and lightweight and came fully charged. I really appreciated the plastic terminal covers. I haven't drained the battery yet, but the are no obvious problems in the few hours I've used it. I will be looking at Goldenmate if I ever do a bigger build. ... show more

  • Light and reliable!
Size: 12V 50Ah
Quality is fantastic! My old one died and I didn’t realize how bad it was until I got this one. It has more power and lasts a lot longer than my old one! I also LOVE that it’s lighter!

  • ROCKIN' THREESOME 🤘
Size: 12V 20Ah
The media could not be loaded. I got (3) of these for my truck that use for Mobile DJ'ing, and just starting to move it indoors. For the video, this was my first test, temporarily mocked up as backup batteries for 3 of my bluetooth wireless speakers. It's a no brainer, because the cost of fabricating these was 1/3 of buying factory replacement batteries. AND THEY LAST LONGER. About 2 hours so far at full volume, and they didn't even drop one bar on the battery meter. These are a game changer for me!! 👍 The casing of the batteries seem kinda fragile, but I never plan on dunking them, or sending them airborne in a sand dune or anything. The terminals are actually metal, as you can see with the magnetic screwdriver, but the posts they screw into are aluminum, so be careful not to over tighten or they'll strip ... show more

  • Working!
Size: 12V 20Ah (2 Pack)
Size was perfect for my mobility scooter. Fit exactly in the battery box, size wise. Had to extend some wiring. See the location of posts(screws) and compare with original battery’s. Just be informed. Came almost fully charged. Powers scooter to top speed. Hill climbing seems to be a challenge in some places. I’m exploring that. Will check back if I figure it out ... show more

  • Excellent batteries for the price point!
Size: 12V 16Ah
So happy to have found these. Upgraded my wife’s mobility scooter. It now has twice the range and the battery box is half the weight. It took a little bit of tinkering to make these work so if you don’t know much about wiring things, I wouldn’t recommend trying to convert from gel, cell batteries. Especially since these are wired in a series and the only charger I was comfortable using only chargers in a parallel. So I needed to put some three-way switches in to prevent short-circuiting when charging ... show more

  • Great Output, Lightweight
Size: 12V 20Ah (2 Pack)
Battery technology keeps getting better and better. I have a solar-powered setup for a webcam and LED light with my house address on it about 200 feet from my house where there is no electricity. The camera draws .2 amps during the day, and .4 amps after dark when the infrared kicks in. The lights are on a timer, and run from dusk until midnight. They draw another amp, so 1.4 amps in total overnight. So this time of year (Fall), with shorter days, I have about 16 amps of draw in 24-hours. I've been using AGM batteries for the past 8 years with this setup and have had to replace them 3 times. The latest was purchased for $200 in February 2024. We're in October 2025 now and the battery has very little capacity. Everything stays lit for a few hours and shuts down. I purchased this pair of 20aH LiPo batteries and wired them up in parallel to double the aH across the pair. My 200-watt panel charged them to full capacity in a couple of hours, and my camera and lights stayed on as long as I wanted them to for the first time in a very long time. I checked the batteries in the morning, while it was still dark out, and they were barely depleted. Hopefully these will hold up the the 5,000+ discharge claim and last me quite a while. The added bonus is that combined they are still a fraction of the weight of the AGM lead-acid battery. ... show more
