12V 12Ah Lithium Battery, 4000+ Cycles 12V LiFePO4 Battery Built-in 10A BMS, 12 Volt 12Ah Deep Cycle Great for Lighting Supply, Solar System, Ride on Toys, Fish Finders, Ups Backup

Some of my equipment operates on 11 to 14 volts and I used to run those with sealed lead-acid batteries rated at ~7 Ampere-hours. I bought pair of these when the older batteries started aging out. They are physically larger than the old 7 Ah batteries at almost twice the capacity (12 Ah). They weigh less than half of the older, smaller batteries but not twice the physical size. I am developing solar charge management and have not yet programmed that project to measure charge efficiency (energy in divided by energy out) but these are out performing the older chemistry. I have purchased this product in a 6 Ah battery that outperforms my older 7 Ah batteries. I am well pleased. I now have four of this model with the first two about a year old in daily service. Bill

Why did you pick this product vs others?: Fantastic battery!! Used it to jump start my Electric Vehicle whose 12V battery was weak. This battery was able to do this several times in a span of 5 days without need a recharge. Battery charge: Charged to full in about 3 hours on a LiFePo4 charger at 1.5Amps Value for money: Was reasonably priced and had the perfect size for my application. Quality: Quality Build and packing just perfect

After unpacking the radio, I hooked it to a LiFePO4 dedicated charger to charge. Then I attempted to use it with a ham radio. It appeared to have no power. I surmised the BMS was “asleep.” I took another battery and hooked it to this new battery and it woke up. I used it for several hours to run a radio without issue. It recharged as expected and is currently supplying power appropriately. Packed in a box with some radios for a trip to AK. We shall see.

Got this battery to go in a Ice Box power box for my new fishing Kayak to power up my fish finder. Battery is exactly as described, arrived on time, charged rather quickly, and powers the box like a champ. Can't wait to get out on the water with it to see how long it lasts.

Zero is not an option. We just opened the package because they were needed now. Two of the batteries have zero volts and will not charge. We are unable to return them even though there is a three-year warranty.

Bought 2 of these batteries, soldered wires on to the leads of the battery. One battery was fine no issues. On the second battery, the terminal once heated up enough to take the solder melted the weird plastic around both leads causing them to come loose. Not sure why I had no issues with the first battery and the second one melted? Couldn’t figure out a good way to secure the battery terminal back after the plastic around it melted so ended up trashing a brand new battery. Update: seller reached out and was super helpful in reaching a solution. Excellent customer service. Great experience dealing with them. Will order from this seller again!

Very pleased with this purchase! It replaced a lead acid battery that weighed twice as much and lasted far fewer hours. Packaging and instructions on this new battery were very well-done, clear, and instructive. Excellent three year warranty!

Good quality, great customer service
