Features
- LIGHTWEIGHT AND VERSATILE - Item Dimensions: 13"L x 6.77"W x 8.66"H. Our 12v battery engineered with Lithium Iron Phosphate (LiFePO4) technology, offering 1/3 the weight, 2x power and 8x longer lifespan compare to a lead acid battery. It is a perfect upgrade for any 12V Deep Cycle battery. It offers 1.28kWh of energy and supports a maximum load of 1536W with a continuous discharge current of up to 120A (peak 500A for 3 seconds), making it ideal for trolling motors. The built-in Bluetooth functionality brings you enhanced convenience, you can monitor the battery anytime, anywhere.
- BUILT TO LAST - Our 12V 100Ah LiFePO4 batteries are designed to deliver over 4000 deep cycles at 100% DOD, with a lifespan of 10+ years. These batteries provide consistent power across all 100 amp-hours, thanks to their flat voltage curve. Unlike traditional SLA batteries, the power output remains steady as the battery discharges, avoiding the dramatic voltage drop that is common with lead-acid batteries. With a full 100Ah capacity, this battery ensures a full day of reliable power, making it perfect for high-demand applications such as trolling motors, RVs, or extended off-grid adventures.
- GRADE A CELLS & SMART BMS - The built-in Battery Management System (BMS) protects your battery from Over Charge and Discharge, Over Current, Short Circuiting, as well as Low and High Temperature for increased performance and longer life. The BMS will automatically cut off the battery and the voltage will drop below 1V. Only when the circuit is cut off, the battery will automatically reactivate after 1 second (No longer need a higher voltage input to activate).
- LOW & HIGH-TEMPERATURE PROTECTION: Designed to withstand extreme temperatures, our 100Ah lithium battery can discharge in conditions as low as -4F (-20C) and as high as 140F (60C). Ideal for rugged & harsh environments. When the temperature is outside this range, the BMS will activate protection.
- We prioritize quality and customer service. Should you have any questions, please contact our directly. Our outstanding support team is ready to assist YOU.
- Autocessking 12v lithium battery is designed for energy storage purpose only. We do not recommend using it as a starting battery for cars.

Guys you need this battery. Every guy does but if you are older listen you will have a better day fishing in that pond or lake because of how much lighter this battery is. You need the charger for this but it is worth it. It charged easy and runs a long time. Easy to use. I would suggest this item.

Battery will not hold charge with less than 6 months of use. When load tested shows bad battery. Seller contacted via phone and email. Customer service said warranty dept would be in touch but we’ve received no response.

When I ordered the battery, I was initially sent the incorrect one. It's not a problem, we are all human! But I reached out and their customer service representative was fairly quick to respond and assist me. I replaced 2 AGM Deep Cycle Batteries with one of these. I was so impressed, I ordered a second one within a week. I'm running 2 of these in parallel and I could not be happier. It's running my 12v trolling motor, inside/outside/navigation lights, and my fish finder. I can now go 2-3 full nights of night fishing from ONE charge.

I used four of these to replace the two Lead acid cells on my Travel Trailer. I had to replace the charger unit in the trailers Converter, but that was easy. I just came back from a full week in the boonies, dry camping. I used these batteries to supply power to a pure sine wave inverter that feeds my Microwave and other AC equipment. (not Air Conditioning) I do have Solar panels on roofl. These batteries didn't even blink, even though I had little to no sun most of the week.

Way lighter and the blue tooth is awesome
Reviewed in the United States on April 29, 2026 by T. L. Rupe
Replaced my old 60 lb lead acid trolling motor battery with this 23 lb beauty. It's slightly more expensive and requires a special charger, but worth every cent. Power seems infinite. I've used it several times all day and it barely discharged 25%. Well constructed. Pony up a couple of bucks and get this if you need a deep cycle battery. Lead acid is obsolete.

I just love this battery for my boat. I will probably never have to replace it again thanks to the Lithium batteries and BMS incorporated in this battery. The next GREAT feature is having an app for the battery I'm never guessing how much battery life is left when I'm out on the lake running on battery only fishing or just anchored out listening to music. I connect to the battery with my phone and check the state of charge if I'm worried I might have used to much battery. I'll come back and update this review as the years go by.
