Great for Lowrance Eagle Eye 9’. Ive used on 8 hour trips and it last all day no problem

Great battery, durable. I use this to run my gold prospecting equipment.

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

Works wonderful. Do not charge with anything more than 4.5 amp, has to be LithPo4 capable charger too.. I have used it for 2 weeks straight nearly every day at least a couple hours a day to run all my lighting and my Garmin for my boat. I use a 100 amp hour for my motor.

Works as it should

decent battery

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.

It's new and has not seen a lot of use yet. However: be aware it's only nominally 12V. Voltage measured across the terminals of the mostly charged battery is 13.6V. If the battery is being used to power sensitive equipment that depends on the voltage being no higher than 12V you will need a buck converter to regulate it. The battery should have a carry strap in its design; it's less convenient without one. The screw terminals are a nice feature, and the overall size and weight of the package is convenient for the intended purpose: powering an amateur radio for field use. For the price it's not a terrible choice if it fits your budget. If I had more to spend I would have looked further.
