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. Review: Impressive battery with built in ampHr compared to others - 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 ## Features - 【BLUETOOTH FEATURE】The Bluetooth 12V 310Ah lithium battery supports real-time monitoring of battery SOC, temperature, voltage, and various battery statuses through an app connection, and also allows for renaming the battery. - 【COMPACT 310Ah BATTERY】The XZNY 12V 310Ah Bluetooth LiFePO4 battery features a compact design, making it 40% smaller than the standard 12V 300Ah battery and 55% smaller than three 12V 100Ah batteries.

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 ### ⭐⭐⭐⭐⭐ Great for Hook Reveal 7ts *by T***N on March 13, 2025* 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. ## Frequently Bought Together - XZNY Compact 12V 300Ah LiFePO4 Lithium Battery (310Ah), Small Size 6000+ Cycles 12V 300Ah Battery, Built-in 200A Low-Temp Protection BMS, Great for RV, Off-Grid, Home Energy Storage, Marine - BOJACK MRBF Terminal Fuse Block 250 AMP Marine Rated Battery Fuse 58V DC Max IP66 Waterproof Fuse Holder 250A - Victron Energy SmartShunt Battery Monitor (Bluetooth) - Victron Smart Shunt - 6.5V-70V, 300 amp --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/673558151-compact-12v-310ah-bluetooth-lithium-battery-small-size-12v-310ah](https://www.desertcart.us/products/673558151-compact-12v-310ah-bluetooth-lithium-battery-small-size-12v-310ah) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-24*
