Compact 12V 12Ah Lithium Battery, Rechargeable 12V LiFePO4 Battery Built-in 20A BMS, 12 Volt Deep Cycle Battery Perfect for UPS System, Replacement SLA, Ham Radio, Water Pump,Solar System,Scooter

I really like the weight and compact size of the battery. It charged up perfectly and was in good condition when received. The handles on the battery are also a nice touch, making it easier to handle. Came with two lengths f screws as well as washers and lock washers which is nice, as other batteries ive got in the past come with nothing. The bms functions well and does everything it says it does. I really really liked that they included a manual that stated all the specs of the bms, such as cutoff voltages, temp cutoff, etc. such a good price for this battery for such good quality. The one thing I was a little disappointed with was them shipping using fedex however and wish they could use ups or even usps. I knew my battery had arrived when i heard the loud *thud* of the fedex delivery driver dropping it on my porch. Tracking from fedex is also hit and miss. Really glad the battery was packaged so well with thick dense foam that protected it when the delivery driver literally dropped it from waist high onto the ground. Over all happy with my purchase and will order from them again. Really hope to see larger capacity 24v batteries from them in the future.

I've used this battery for my trolling motor and it's great. I've replace this unit with 2 x 12v lifepo4 battery that didn't have bluetooth. The thing I find nice about this battery is the built in ampHr for capacity, I was tired of looking at volts trying to understand how much more juice I have in it. This is a great battery, it's rare for batteries to also have the ampHr build it, save you money so you don't have to buy a shunt

This battery is for my Hook Reveal 7ts fish finder on my kayak. . After using a different brand for similar battery (12V 7.5Ah) for a year and half, that battery would only last 3 hrs. Since it was 30 $ battery I told myself for 1.5 years that was ok and ordered another. The new battery was used twice and only lasted 1.25 hrs and then almost 2hrs. I fish 4-6 hrs, so I sent it back and began a search for similar battery that was same size as it has to fit in my kayak battery holder in the sealed hatch. I found this brand XYNZ and was happy to find the right size with more power 12.8 V 12Ah and consistent reviews and for only a few dollars more. It arrived a lot early then originally schedule (Yeah). Was packaged very well and came with a nice little manual. I followed the instructions and charged it up. Took it out to fish and it lasted around 4 hrs without any problems. So I didn’t charge it to see how long it would last and took it out on day 2 and it lasted another 4 hrs. So I took it out on day 3 and fished 5 hrs without any problems. At this time my friend was here and used his tool and it was 11.8V. So I put it on charge. My friend also helped me to set up the voltage to display on my fish finder so that I know when it gets to 12V and can charge it up when it reaches that amount. I will follow up if I have any problems and also will follow up in 1-2 years to let you know if it’s still going strong. My other battery should have lasted a lot longer than 1.5 years! This company sounds good and has a 3 yr replacement on it.

Nice battery. I used it to replace an 8 ah lead acid battery in a DIY ammo box power station.

I ordered this battery as an addition to an existing LiFePO4 backup system, and it has been in service for a little over a week now. So far, no issues with the battery, arrived at a healthy 26.4V charge & has been floating at 27.3 since then. The compact size is really great for under-desk installations. The casing seems to be rigid enough to hold up to bumps and scuffs. Would recommend so far. Side-mounted terminals would be nice as an option for some installs.

Have been using the battery 310Ah as an emergency power station for almost 8 months now and I've had zero issues. Battery life lasts me a couple weeks with steady use with solar, and has proven to be an excellent value for the price. These are compact batteries and not all that heavy, so they're easy to carry/organize. The posts are an M8 style and come with short/long threaded studs to meet any need you may have which make them easy to setup! Would definitely purchase again.

This is a thank you to this company as they took care of my problem with the warranty. I bought 2, 24v 100ah batteries non smart versions last year. I rarely used it but tailgating season for college football is back and one of my batteries would not put out any power to my inverter nor would it charge. It did show 25v. I tried various ways to wake it up with no results. I contacted them and we went through some back and forth to test and even though we couldn’t get it to work properly. They did accept my return and sent me a replacement that is working perfectly. I will buy from them again moving forward. Great batteries that are compact and well built! Thank you again for your support and help.

Bought 3 of these and couldn't figure out why I was running out of battery halfway through my flights. I finally put a voltage meter on them during charging to understand what was going on. Either a bad batch of three or incompatibility of their BMS systems with well respected tried and true Noco 5 and Noco 10 chargers in lifepo4 mode. The XZNY top out at 12.5v (less than a 20% charge) which was enough to power up my instruments but obviously left me high and dry no pun intended 😲
