The 20 A continuous BMS makes them a much better choice over most other batteries - aside from Dakota Lithium that are at least 2x the cost, I haven’t found any other in this size that are 20 A. Also these are 12Ah that fit into the same size as a 10Ah battery. So they have more continuous Amps and more capacity. Note, these will still limit your UPS (to 240 Watts if one battery and 480 Watts if 2 batteries), but that is the nature of these smaller LiFePO4 batteries and not a fault with the batteries themselves. I simply label the UPS with the new limit so I don’t forget. I’ve used 4 of these batteries in 3 UPS so no issues so far. Review: For the price, can't be beat - I have been using this to power my Garmin 93sv and GT-54 UHD transducer. This batter has worked great. Considering the price, this battery is hard to beat. This lasts me all day on the water and holds the charge consistently above 12 volts all day. I have had no issues so far, going on about 5 months of use so far. ## Features - 【THE PERFECT CHOICE FOR UPS SYSTEM BATTERY】XZNY compact 12Ah lithium battery offers the same dimensions as a lead-acid 9Ah battery but with triple the available energy (54Wh vs 153Wh).

This batter has worked great. Considering the price, this battery is hard to beat. This lasts me all day on the water and holds the charge consistently above 12 volts all day. I have had no issues so far, going on about 5 months of use so far. ### ⭐⭐⭐⭐⭐ 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 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 - ULTRAPOWER 4-Amp 14.6 Volt LiFePO4 Battery Charger,12.8 Volt LiPO Lithium Battery Charger,Smart Charger Maintainer for Cars,Motocycles,Golf Carts,UAV,Fishing Boat and Deep Cycle Batteries. --- ## 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.co.za/products/591551545-compact-12v-12ah-lifepo4-battery-for-fish-finder-ups-lighting](https://www.desertcart.co.za/products/591551545-compact-12v-12ah-lifepo4-battery-for-fish-finder-ups-lighting) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-07*
