GOLDENMATE 12V 200Ah LiFePO4 Lithium Battery, Rechargeable Battery Up to 15000 Cycles, Built-in BMS, Max 2560Wh, Perfect for RV, Camping, Solar, Marine, Trolling Motor, Golf Cart, Off-Grid

Have had it about a year, probably at about 25 cycles on it. Use it mostly for a trolling motor on a kayak. Can run for hours at full throttle will no loss of power. Also handy to use for other 12v needs. Super light so makes it easy to use. Only gripe is it's difficult to know the state of charge. I just know my motor draws 10amps so I have about 5hours run time. Same goes for charging, you just keep charging it until the internal computer won't take a charge anymore. Helps to have an intelligent charger so you can keep track of how much you think you used vs how much went back in. Lots of batteries out there but this seems to be a good brand.

Was actually nervous about this purchase, but turns out it was a solid battery! Have been using it for more than a year, no issues, it holds up!

We have a small solar power system set up for the workshop with several of these connected. They're more than enough to run our LED lights all day, and power a workshop fan when the sun is out. Looking forward to expanding the system in the future, and I'll gladly run with higher capacity batteries from the same manufacturer.

Bought this to replace old dry wet cell batteries in a power pack. The size was the same although the terminals were on opposite side of the previous batteries. I was able to make the cables reach and took it a trip to use to recharge devices. Worked great and will see what the long term brings.

So ill do a review because I ran this battery to zero (you can do that with lithium) I didnt see any reviews with this information in it. if you run it all the way to zero the battery will report zero volts. It is not dead. You simply need to jump it and add a little 12volts to it for 3 seconds. That will give the BMS time to start up and it will report 10 volts. Then it will take a charge.Good battery Nice capacity and a good weight. I love mine. Ive had it a year now. Just killed it and learned that you just have to give it some juice to get it to start. It isnt dead.Enjoy!

I purchased a Golden Mate battery expecting reliable performance, but unfortunately, it failed prematurely. After some use, the battery completely stopped outputting 12V. Upon inspection, I discovered that cell number 4 had died and was producing 0 volts, effectively rendering the entire battery non-functional.Attempts to recharge it were unsuccessful the battery won’t take a charge at all, likely due to the imbalance caused by the failed cell. It’s extremely disappointing for a battery that should be built to last, especially since it’s marketed for off-grid and critical backup use.I expected more durability and quality control. If you’re depending on this battery for any mission critical application, I’d recommend looking elsewhere or at the very least, keeping a close eye on cell voltages with a BMS or external monitor.Support has ignored my emails or is backed up with support tickets.Purchased 2 months ago.

Works like it should. . . .nice battery and cheap price.. . . .drained every night and comes back for more.

Exactly what I needed for my DC power box that I carry in the car to power my Mobile Alinco DR-MD520 triband VHF/UHF amateur radio. The battery just the right size for the power box, came with all connecting hardware and is easy to charge in or out of the box.
