GOLDENMATE 12V 16Ah LiFePO4 Battery, IP67 Waterproof, 12V Lithium Battery w/ 5000+ Deep Cycles, Built-in BMS, Premium Lithium Iron Phosphate Cell, Ideal for Solar, Marine, Fishfinder, Off-grid camping

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.

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.

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

Power for days. Seems to have near rated capacity. Runs power wheels for a couple hours no issues. Holds power/speed better for climbing hills. This bad dog is certainly not IP67 but might be cracking IP54 comfortably -- it's more dust and splash resistant, and I'd hesitate for a good long while (and re-think my life) if I ever thought about dunking this bad dog under water. Shucks.

This little battery was way better than I expected. Have a Amped outdoor battery comparable in voltage and amps and this one lasts longer between charges. Highly recommend it.

Only had it for about 2 weeks. Still testing out it's capacity. But, so far so good. Holding up well on it's 1st charge. A little larger than I had hoped but to be expected for it's AH rating.

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

This was a perfect fit for my husbands boat and it works great.
