What is this 12V 100Ah Group 24 marine starting battery designed for?

The LiTime 12V 100Ah Group 24 Dual Purpose LiFePO4 Battery is designed for compatible 12V gas outboard motors. It works as a marine lithium starting battery with strong cranking power and is built for boaters who need a smarter Group 24 lithium replacement for compatible marine starting batteries.

Can this Group 24 marine cranking battery start a gas outboard motor?

Yes. This 12V 100Ah lithium starting battery delivers up to 1200A HCA, 1000A MCA, and 900A CCA at -10°C to support compatible gas outboard motors. Before use, please check your outboard motor’s required cranking amps and charging system compatibility.

What does “dual purpose” mean for this Group 24 marine starter battery?

For this product, dual purpose means the battery is designed for marine starting use and compatible marine lithium battery applications according to the product manual. It is mainly built to start compatible 12V gas outboard motors. Do not assume it can power all onboard DC devices unless your system requirements match the battery specifications.

Is this Group 24 dual purpose battery compatible with Mercury outboard motors?

This battery supports compatible Mercury gas outboards when the motor’s starting current, charging voltage, and voltage regulator requirements are met. Always confirm your specific Mercury outboard model’s battery requirements before installation.

What is Smart Power Reserve?

Smart Power Reserve automatically keeps backup power when the battery runs low, helping you restart your outboard motor instead of draining the battery completely on the water. It helps reduce the risk of being stranded during boating or fishing trips.

Can I use this Goup 24 battery to start a car, truck, motorcycle, or tractor?

No. This battery is not designed for cars, motorcycles, trucks, tractors, or other land vehicle starting applications. It is designed for compatible 12V gas outboard motors and marine use only.

Fantastic battery lightweight I love the app and the ability to see my status

Fantastic battery lightweight I love the app and the ability to see my status. I don’t want to research these batteries have a great reputation. Can’t wait to put it to the test.

I’m getting a over voltage off this battery 14

I’m getting a over voltage off this battery
14.5 volts and it immediately shuts down my graphs on over voltage emergency
They stay on after I run the battery down a bit but very dangerous running the river with no graphs

Have run this LITIME battery two times since

Have run this LITIME battery two times since installing ! Ran two graphs over 8 hours with zero issues and power only dropped 2% !!
Love the phone app monitoring the 12 and 24 boat batteries !!

Only had approximately 1 month and have taken the boat out twice. So far it has performed flawlessly. Starts my 90hp Yamaha quickly and appears to charge well when the motor is running. Went out for 4 hours, turned off motor and ran electronics...depth finder and stereo while on the trolling motor (separate Li-Time 24v TM battery). When done fishing, according to the app on my phone, the battery was still at 96% and cranked up the motor right away. I really like the lighter weight of the lithium battery. Ready for Li-Time to come out with cranking batteries for my 25 Contender with twin 200's!!!
