12.8V 7Ah Lithium LiFePO4 Deep Cycle Battery, Built-in 10A BMS 2000+ Cycles Lithium Iron Phosphate Rechargeable Battery for Solar Power

I'm using this to power a 12v lighting system on my electric bike. It's nice and compact, lightweight, but still runs a bunch of LED lights for quite a long time. The case and the contacts both feel very sturdy and waterproof. I had no issues connecting to the battery with some spade terminals. Haven't had any hitches at all since installing it, lights run at full power for days.

This is a decent LiFePO⁴ battery in a compact waterproof enclosure. The battery has standard f2 terminals and couldn't really be any easier to use. I won't repeat all of the battery specs here, as you can certainly read them on the product page or on the photo I provided of the battery.This battery is currently being used along with a solar panel and MPPT charger to power a wifi enabled cellular modem and low power remote security camera system.I'd almost like to have something critical to say about this battery, but I've had no problems and everything's held up great up to this point.The battery provides more than enough power for the electronics overnight. The battery has just enough capacity at a full charge to keep everything running 24/7 for almost 2½ days without recharge after a heavy snow, which is excellent for my needs. It's a decent battery I think, and I believe it is a good value for the money as a ready to use battery somewhere around $15 to $20.-This is an impartial review of the product listed as "12.8V 7Ah Lithium LiFePO4 Deep Cycle Battery, Built-in 10A BMS 2000+ Cycles Lithium Iron Phosphate Rechargeable Battery for Solar Power" ASIN B0DJM421LW and applies only to this specific product.

Amazingly Lightweight couldn't believe there was a battery in there but it charges and lasts as long as I'd expect, very nice product

This is a 12.8v 7.2ah lithium iron phosphate battery (LiFePO4). When I received this battery it came in a plain brown box, no paperwork, no specs, no instructions. According to the listing pictures you can connect these in series or parallel but having some paperwork that came with the battery to confirm that would be reassuring.Upon arrival, the battery measured 13.13vdc. I put a 2a LiFePO charger on it and it took a few hours to top off. I then let it sit overnight and tested it in the morning. To test it, I connected the battery to a watt meter that measures AH and used the battery to transfer power into my EcoFlow delta 2 power station. The battery did fairly well putting out Just Shy of its rated 7.2ah at 7.15ah. That’s close enough for me. During the test, the voltage definitely dropped more than I’d like to see, but it delivered constant power. The voltage does drop under load, and bounced back up after the battery cut itself off.This uses standard sized F2 terminals.

I like to experiment with battery projects from time to time. I’ve built lithium battery packs for a variety of uses, using lead acid and lithium ion but not so much lithium iron phosphate. Most of my project require a 12v power source. I decided I wanted to try a battery that was ready to go, so I ordered this one. What I liked about it was its small size but lot of power. 7Ah at 12v for a small form factor can do a lot. Lithium Iron Phosphate batteries are lighter compared to Lithium Ion. I first charged this battery to full, which was only a few minutes. I suspect this was mostly charged before shipping. I then connected a small power inverter using alligator clips to the terminals. The inverter then supplies USB or AC type power out. As long as you understand the limitations of how much the battery can output and don’t overdraw the power, you should be good. I use mine to charges and run low voltage devices such as in events when commercial power is out. Ideally, for my purposes, this would do nicely in a portable box that is self-contained, providing the ports needed to power devices. I was very impressed with my experiment so far with this battery and added bonus for the indicator on top to tell you how many volts it has.

Seems well made, and took a charge without issue. But on testing, I am only getting a little over 5Ah, nowhere close to the claimed 7.2Ah. (Cycled ant tested it again to double check, with similar results.)So either this is mislabeled, or they've used low quality untested cells inside. Or both!?I will put this into service, and continue to monitor it's performance - and plan to update this review if it give me any surprises, whether good or bad.

This 12V 7.2Ah LiFePO4 battery appears to be a quality and reliable power source. Unlike some batteries that fall short of their advertised specifications, this one actually (slightly) exceeded them. In my testing, I measured a capacity of 7.25Ah, indicating high-quality cells and proper balancing.It is a perfect fit for my APC Back-UPS CS 500 , although it was too large for my 350 model. The battery's BMS functioned as advertised, with a high voltage cutoff of 14.5V and a low voltage cutoff of 9.5V. It also handled a 15 amp test load for 30 seconds without any issues. I have seen up to 10AH LiFePO4 batteries this same size, so if you want to maximize the capacity in this form factor you may want to consider something else. This battery is priced competitively for its capacity.This LiFePO4 battery offers a significant advantage over traditional lead-acid batteries with its extended cycle life and reliable performance. Its performance, safety features, and compact size make it a valuable upgrade for UPS systems, power wheels, fish finders, portable power inverters, and other devices.

A drop-in replacement for the very popular PS 12-7 battery used in burglar alarms, uninterrupted power supplies (UPS) and a host of other stand-by devices. It is the same physical size with the same terminals. It maintains the voltage throughout the discharge cycle. With the 10-Year expected life time and 2,000 charge, discharge cycles, it is a far more economical battery than others. Well pleased.
