Our Fukuai 12.8V 16Ah LiFePO4 Battery is maintenance-free, which has a series of unique advantages such as high working voltage, high energy density and long cycle life. LiFePO4 technology provides a very flat discharge curve, which means sustained power to the end of the cycle. The battery’s lithium chemistry reduces the weight of traditional lead-acid batteries to less than half, while greatly improving performance and capacity. They are not only designed for storing electricity easily, but also for providing you with long-lasting peace of mind, and their huge durability allows you to use them in indoor or outdoor needs without worries.

I use this for portable ham radio operations. I can easily get 2 hours out of it while transmitting often. It may last longer, I just cant sit there that long. ;)

These batteries have a metric size terminal which is super hard to find connector bolts for, especially since it doesn't come with them...

These batteries are not LiFePO4 (lithium iron phosphate), they are in fact lithium-ion 18650 cells wrapped in a pretty housing. Since lithium-ion have more charge cycles will be a better product for my project. Each pack has a BMS so be aware how you hook them up as not to bypass by mistake.

Used it in a power wheels land speeder. Function like it should.

Used two of these in parallel (12v, 14.4Ah) as with a solar panel and small charge controller to provide power in my kid's cabin.They occasionally powered four switched LED lights (3w each) and a switched ventilation fan (5w).Bought them Nov of '23 and they stopped taking a charge August of '24 with, intermittent use.That's only 300 or less charge cycles before failure, by my math...I'll be sticking to lead-acid batteries.

I bought this to replace a 12V 8Ah sealed lead-acid battery in a Samson XP106 portable speaker system. The SLA battery died with little use due to the pandemic and lack of charging it. This battery is several pounds lighter (which is very useful for portability) and should last longer at 10Ah.Although I got a LiFePo charger, that didn't work with the battery installed. Since the seller says it is okay to use in a UPS, then it seems that it is okay to use in devices that self-charge their own SLA as long as those are for 12V. The Samson speaker has it's own charging circuit and seemed to work to charge this battery. I will have to trust in the BMS and hope this last longer than SLAs.

Battery drops right in to the unit! I tired of replacing the AGM battery with its quick loss of capacity, and the internal charger causing it to swell up into oblivion.This requires a small modification to work. Cut the wire from the the back of the charge plug. Install a small plug on the side of the unit being careful of placement so it will not interfere with the PCB or battery. I installed the charge wires with a 10 amp fuse by splicing into the battery wires. Now the unit can only be charged with a compatible external charger or solar charger. I built up a cable/plug for my charger or solar charge controller, and can use this plug as a 10 amp output port.Since I was on a roll, I installed a 20 amp battery selector switch on the top of the unit and a fused (20 amp) external battery plug on the other side of the unit allowing easy use of external batteries if needed. This modification requires greater effort and care due to limited space and switch placement, insulating the switch terminals due to risk of shorting to the board. Due to space limitations, I used a SAE plug (again careful placement), and created a adapter cable to Anderson Power Pole connectors which my extra batteries use. When you open up your Goal Zero you will see if this is a project you want to take on.This battery has much higher capacity and greatly lighter in weight. Installing the new charge plug (measuring and drilling required), and splicing in to the battery is relatively easy. This totally upgraded my GoalZero in its capabilities and reduced the weight significantly!Highly recommend.
