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

Decent capacity, lightweight, works great for multiple uses, when paired with a battery box works great for camping and running a small inverter. Good value for price/capcacity, Battery is well made and ha sturdy connections. Simple to setup and add to backup power supply.

Worked great with my electric fishing reel. Lasted 2 days deep sea fishing with a ton of life left.

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.

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.

These have been awesome and are about a third of the price of higher end batteries. I’ve been on around 10 trips now and depending on the weather they last for hours. I run a 36v Rhodan on my 27 Gamefish and have had all conditions so far, wind and high swell. In rough conditions they lasted about 4 hours, and on calm days they lasted close to 8 hours and kept me on the spot. I have had no power surges and they work fine with my fuse. They charge fast and are back to full in about 2 to 3 hours with my charger. The pic is from when I was about done installing, but that charger is what I use. I mounted them on a starboard platform I built under the T top console next to the toilet and it was easy to install. One thing I will say is the orange caps provided do not really cover the terminals, but I am not worried about that.

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.

Nice battery-fast ship-thank you

Bought two. One was installed in a computer UPS (replacement for SLA 12v) and works great. Check the current reqs for your UPS! The 2nd went into the saddlebag of a motorcycle, to act as an emergency battery booster. Very light! Note: this is not a motorcycle cranking battery. In the case of extended cranking (out of gas, carb problems, cold weather), it can be attached in parallel with the onboard lead acid, to partially recharge the cranking battery, and then support 12v while cranking. Get yourself a 10ga connector like used on solar panels or a battery float charger, to make connection in the field quick and easy. Lead acid batteries can suffer instant death, I'm too lazy to push start. Note: Honda Goldwings are notorious for failing to fire the ignition below 11v, using this battery as a "boost" worked the trick when night time temps whacked the cranking battery and prevented starting.
