GOLDENMATE 12V 50Ah LiFePO4 Battery, 10 Years Lifespan & 5000+ Cycles, Max to 640Wh, Rechargeable Lithium Iron Phosphate Battery with 50A BMS, Perfect for Solar, Marine, Trolling Motor, RV, Camping

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.

I pickup up a pair of these on offer, over a year ago, not knowing how they'd perform, and was pleasantly surprised. I've been using them in series 24v for seven months to power my appliances off grid and have had no issues at all. I've been able to run my washing machine, microwave, vacuum cleaner, electric kettle without a hitch. I haven't done a capacity test to check if they have Grade A cells but they work pretty well. No issues whatsoever. I would buy them again.

I've been using this battery for almost a year now! No problems at all! The battery is very lightweight, which is important to me since I use it on a sailboat. Basically, just plug it in and play without any problems! The only thing to keep in mind is that this is not a starter battery, as the electronics limit the output to around 200 amps!

amazed at the power of this battery considering how light weight it is. This is a major improvement on deep cycle batteries. Look forward to trying these as a set in a golf car. Product is as good as advertised.

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.Update: Since the battery was charged and put aside after receipt, this means that the battery was normal when received, but was damaged after being put aside. The current battery storage environment is very humid. Analysis shows that improper storage has caused corrosion and damage to the battery pack components and made it unable to charge.Apparently having the battery inside a garage isnt proper storage.

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.

I love lithium batteries! I’ve only used them a few times but so far they perform like they should. What a great price! Hopefully they will hold up!

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!
