Compact 12V 18Ah LiFePO4 Lithium Battery, 4000+ Cycles 12 Volt Lithium Battery Built-in 20A BMS, 12V 18Ah Battery for Garmin Fish Finder Battery, Power Wheels, Mobility Scooter, Lighting Supply

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.

Kayak fish. I have a trolling motor I run with a Litime 100ah battery that is amazing. I purchased this and will purchase one more for my two 7inch Garmin fish finders. These will save you a ton of weight, are cost effective, and much more durable than lead acid or an agm. This 18ah weighs less than a 12ah lead acid I have. This was well charged when it arrived. I’d recommend LiFeP04 batteries off Amazon as they are generally more cost effective and just as good as the “outdoor” brands like Amped or Dakota.Please note that you do have to buy a LiFePO4 battery charger (these require like 10 to 20 amp hits to charge). A standard charger will not do the trick. Amazon has several smart chargers that work for this.

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.

This is my third battery from this company. Each battery has arrived in excellent condition and have supplied power for my portable amateur radio set up on each and every one of my portable outings. I have recommended them to my fellow Hams and look forward to using this battery as it’s a little bit larger then my last one. Should give me a lot more time on the air. 73!

About 6 months ago (Nov 2024), I purchased 2 of these for a small standing scooter. They were the 10A BMS model. They worked perfectly in the scooter, and I performed a test in my UPS and they seemed to work fine at the load I had them at (~230W/9.5A), so I planned to purchase more for two UPSs I need to replace the AGM batteries for.I come to find they've since upgraded this to 20A BMS, works for me, I bought 4.What actually arrived was not what I expected though. Two of them were the 20A model, and two were the older 10A model. There's no actual markings on the battery themselves that I saw which would indicate the BMS size, so I referenced the spec sheet on the included user manual.I ended up exchanging the 10A ones, and the replacements that arrived were also the 20A BMS I expected.They are now installed in two APC UPSs (1000VA and 1500VA) and work fine. The load on them is about ~250W each, so the current draw should be well within the BMS tolerance.I haven't tested the actual runtime with these yet, but I don't expect worse runtime than with the AGM ones.Anyway, I recommend these batteries as safe alternatives to AGM: They are lighter, and aren't fire-prone like other Lithium technologies; however double check the BMS rating in the manual when you get them, to confirm they're the 20A BMS, assuming you need that size.

These batteries are beasts. I originally purchased 2-100ah batteries before I found these. They are the same physical size as the 100ah ones, but are 3x the capacity. BMS system protects against over/under voltage, over/under current and over/under temperature.That being said, I still installed BOJACK MRBF terminal Fuse Block 200 AMP fuses on the positive terminal. The BMS will prevent over current draws, but this protects an attack from the other two batteries (yes, I bought 3 of these) that are wired in parallel. The fuse will blow if there is any attempt to backfeed into it.My only gripe is I wish there was bluetooth connectivity to the BMS so I could monitor the individual cells. I did install a Renogy Shunt that will monitor the battery system as a whole, but would've preferred to see the individual battery performance.For the price, these things are amazing.
