12V 100Ah Mini LiFePO4 Lithium Battery BCI Group 24 100A BMS 1280W Rechargeable Lithium Iron Phosphate Battery 6000+ Cycles Perfect for RV, Solar, Home Energy Storage

These things are a huge upgrade and perfect for my boat. I never have to recharge them and they last MULTIPLE trips out onto the lake, even with music blasting and using my trolling motor for a couple of hours. I ended up also upgrading the entire electrical on my boat to these, besides the starter battery because these are not recommended for that. Also I had to make a separate circuit so that the engine doesn't charge this battery because its an older style motor with a rectifier that isn't supposed to charge a battery like this.

As an economical brand, I was skeptical at first but after 6 months of use in our travel trailer, I’m pleased with its performance so far. Hopefully it will perform as expected from a lithium battery.

Battery lasted FAR longer then expected. Based on load, it should have lasted 16 hours... it went 84 hours before quitting. For cost and power output, I have to say I am impressed and I am VERY hard to impress

There batteries came partly charged and well-packed. I bought them to replace 2 Battle Born 100 AH LiFePo batteries that were 7 years old and not putting out full power any more. The Dumfumes are working great, charging fast and effortlessly powering my microwave through a 2000 watt inverter with little voltage drop. Check out Will Prowse's tear down on YouTube where he finds them of very high quality! These batteries are an outright bargain.

High quality and well built. Works great for my trolling motor setup.

Very outstanding battery going to buy more

The terminals are a pain. Order you some terminal post that screw into m8 threads. But the batteries are lightweight fit serious 24 space like they should. And my camper has went a week without going down so far. So overall good for the price.

Great deal this works xlnt
