12V 100Ah LiFePO4 Battery Built-in 100A BMS,Group 31 Lithium Batteries Deep Cycle & 10 Years Lifespan for RV, Solar Energy, Off Grid, Trolling Motor

Good item and arrived as expected

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.

No information sheet, nothing about the battery, only thing is writing on sides of battery.. bought 2.....??? What charger to use? Does it have blue tooth? What safety precaution??Very disappointed!!

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.

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 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.
