    • So far, so good!
Style: 12V 100Ah MINI
I really did not have high expectations because at the time it was the cheapest battery on Amazon based on its specs. But, I have had no issues and as of now. I have been using this thing for everything I can think of! It's been an extra battery in my skoolie for maintaining a charge on my power station, a trolling motor battery, it has powered lights while I DJ parties twice and to be so small and light, held a charge really well. Actually, it has sat on the floor in my garage for over a week and is still maintaining a 13.2 charge with volt meter attached! ... show more

Style: 12V 100Ah MINI
Super strong. This battery ran a full size freezer at Burning Man easily for 10 days. The Freezer drew 30 watts, 24 hours a day, sometimes it drew a little more. 100 watts just for a minute when it kicked on. Mine you a had this battery hooked up to a 400 watt solar panel, a solar controller and a quality 1500 watt inverter. ... show more

    • good product
Style: 12V 100Ah MINI
1.Solid Choice for Trolling Motor I used to use a lead-acid battery all the time for my trolling motor, and the battery was fine at first, but it didn’t hold a charge as well after a few months, and it was much heavier. Now I’ve been using this 12.8V100Ah lithium battery for my trolling motor during fishing trips, and know the difference is night and day. It’s awesome! The rechargeable battery lasts all day long on the water without losing power. Perfect for a full day of fishing, and I love how reliable it is in saltwater environments. Highly recommend it for anyone looking for a solid marine deep cycle battery! ... show more

    • 3 year warranty isn't any good if there isnt a way to contact them.
Style: 12V 100Ah MINI
Bought this a year ago for my trolling motor on my kayak. Worked great until two days ago. Battery is dieing unexpectedly fast, and will not fully charge. Tried to contact them but can't find a way to. Hopefully they see this and honor it so I can change my review. Depending how that goes I may buy a second from them as a back up. ... show more

The DEASON 12V 100Ah Mini LiFePO4 Lithium Battery appears well made and good quality. I fully charged the battery and ran a capacity test on it. I got 103 Amp hours I feel this is amazing in such a small package. The ability to surge 300 amps for 3 to 5 seconds makes this an ideal replacement battery for my golf cart lead acid batteries. ... show more

    • Not as pictured. Same specs and dimensions
Style: 12V 100Ah MINI
Received this one instead: https://www.amazon.com/dp/B0BVDPG2JN?th=1 . No info on how to reactivate the battery once protection has tripped. No low temp thermal charge/discharge protection (not important to me) in any description or the manual that comes with the battery. Otherwise, seems to work as expected. I drew 100A from it as a test. ... show more

    • Excellent for Boats and Emergency Backup
Style: 12V 100Ah MINI
I needed a reliable 12 volt lithium battery for my boat’s trolling motor, and this one delivers! But what really surprised me was how well it also works for my security monitoring system. The rechargeable battery keeps everything running smoothly, and when we’re camping in the RV, it powers the lights and keeps the cameras on at night. It’s versatile, efficient, and holds up well in all environments. Whether for fishing or emergency power needs, this battery is a game-changer! ... show more
