Features
- 2 15000+ DEEP CYCLES AUTOMOTIVE-GRADE LONGEVITY Each 12V 100Ah battery is built with automotive-grade LiFePO4 cells, delivering 15,000+ deep cycles at 60% DOD, 6,000+ cycles at 80%, and 4,000+ cycles at 100%. Far beyond lead-acid batteries, this 2-pack ensures long-term, stable power for RVs, trailers, UTVs, solar systems, and off-road setups that require high durability and lifespan.
- DUAL 100A BMS SMART & SAFE FOR VEHICLE SYSTEMS Each battery includes a 100A BMS offering full protection from overcharge, over-discharge, overcurrent, overvoltage, short circuit, and temperature extremes. Designed for automotive, marine, and mobile applications where safety and durability matter most.
- 2 21.9LB LIGHTWEIGHT DESIGN EASY INSTALL, GROUP 24 SIZE At only 21.9 lb each, these batteries are 50% lighter than typical lead-acid models and sized to fit standard Group 24 trays. The drop-in design makes them ideal for RVs, trailers, campervans, boats, and mobile power units.
- LITHIUM UPGRADE FOR 12V VEHICLE BATTERIES Ditch the acid, leaks, and heavy maintenance. These LiFePO4 batteries are the perfect plug-and-play replacement for 12V lead-acid batteries used in solar rigs, off-grid trailers, boats, and RV backup systems.
- DIY POWER EXPANDABLE FROM TROLLING TO BACKUP POWER Supports series & parallel connections (up to 4S4P) to scale capacity up to 20.48kWh. Suitable for powering trolling motors (3070lb thrust), car fridges, CPAPs, backup vehicle power banks, and more.
- Wide Operating Temperature Reliable in Harsh Conditions Designed for outdoor and mobile setups, each battery operates safely from -20C to 60C (-4F to 140F), ensuring stable performance in extreme heat or cold. The built-in BMS offers temperature protection to prevent damage from overheating or freezing. At altitudes below 2000m, discharge temperatures can reach up to 70C (158F). For best results, store at 2125C (7077F) during off-season.
- First Use NoticeTo protect battery health, some units may ship in 0V protection mode. Use a 14.6V LiFePO4 charger with 0V activation to wake it up before charging. (e.g., 14.6V 8A charger with 0V function)

I got this 12V 7Ah LiFePO4 battery specifically for use in small solar generators, and it's proven to be a great choice for powering lights and pumps around my garden. For the price and capacity, it punches above its weight—compact, lightweight, and delivers a stable voltage right out of the box. Mine arrived pre-charged at around 12.9V, which meant I could plug it into my system and get going immediately. No fuss, no prep, just power on demand. What makes this battery stand out is how versatile it is for low-to-mid draw applications. I’ve used it to run 12V irrigation pumps, string lights, and even charge small USB devices through an inverter setup. It doesn’t sag under load like some lead-acid units I’ve used in the past, and it holds a charge well over time—especially useful for sunny-day charging with solar panels and nighttime use. Build quality is solid. The casing feels durable, the terminals are clean and secure, and the integrated BMS (Battery Management System) gives me peace of mind when wiring it into DIY setups. I’ve accidentally over-discharged similar batteries in the past, but this unit seems well protected, and the BMS does its job without needing babysitting. You can tell it was made with longevity in mind—LiFePO4 chemistry plus a 10-year lifespan promise make it a smart long-term investment. I wouldn’t use this for high-draw devices or anything with a starter motor—this isn’t built for cranking amps, and the product description makes that clear. But for everything else—solar power banks, garden setups, backup lighting, RV electronics, small scooters—it’s a great fit. It’s also light enough to mount almost anywhere without needing extra support or ventilation like heavier sealed lead-acid units. All in all, this battery is a reliable and efficient option for anyone doing low-voltage, off-grid, or DIY power work. I’ll likely be picking up a few more to expand my system or build out additional garden tools. Highly recommend for the price and performance.

My desktop UPS recently started complaining about a bad battery so I figured I'd try something a little bigger. This one of course doesn't fit in the case but fortunately the wires are long enough. After hooking it up everything functions perfectly and the UPS is none the wiser that the battery isn't standard. I can tell there's the extra capacity there in our annoyingly frequent power outages with all the storms lately. Other than that it's your average battery with a reasonably sturdy plastic case and spade connectors. This one works well.

Seems to be good buy for now. Two of the four took longer to fully charge. It’s been 3 days and no issues using with a 48 volt solar charger. I’ll report back if any problems come up.

I ordered this battery for an emergency power supply used to back up a surveillance system and a modem. The voltage initially was 12.3VDC, and after about an hour of charging with a 3A lithium charger it was showing 13.1 volts. In my initial short tests the battery worked perfectly as expected. The lithium battery is a great upgrade from ACM batteries. The only issue to be aware of is with this battery's management system it will no longer take a charge if the temp is below 32 degrees F, and will no longer supply power below -4 degrees F. With those limits in mind I would definitely recommend it to others.

This is a nice alternative to older lead acid batteries, it's lighter and tends to hold its charge longer. I originally got this to use in my gate opener, but the battery tab/terminals are larger than what the harness uses. (I'll get around to putting new connections to that harness some day). I've been using it with a 12v inverter (with alligator clips) and I've been able to power my small TV and charge devices away from the house and truck. It's worked great for camping and when I'm working in the field and need a power source.

Ordered this: 12V 7Ah LiFePO4 Battery, Rechargeable Lithium Battery - to use in a fish finder over the winter. With the extra temperature tolerance and lower weight these are perfect for that kind of application. The price is good, last year they were going for almost $40. I like that this seller offers a 1 year warranty which is somewhat atypical. I tested mine at 13.3 volts out of the box and hooked it up to a smart charger to top it off. These do have slightly different performance than lead acid, the charging and max current are different so you should have a lithium battery charger... don't put them on a fast charger :) Well packaged, construction looks good. Will update review if I run into any issues over time... with batteries hard to know right away.

I was initially wondering about the quality of the battery given the price point, but I’ve been pleasantly surprised. It doesn’t disappoint in comparison with more expensive alternatives. It met my expectations and I would recommend it given it’s a great value.

I've been collecting these smaller lifepo4 batteries for certain usage. These are 12v so there's various usage for these. These smaller 12v can run power wheels trolling motors etc... When you need 24v, just series 2 of these together. This is only a 7ah battery but it comes in a bigger case. Same size case as a 8 9 or 10ah battery. Once you go down to 6ah, it comes in a smaller case which I like.
