4 Charging Options for Different Boat Setups
Recharge your battery in multiple ways depending on your setup. Use a 14.6V 20A LiFePO4 charger in about 5 hours, solar panel + MPPT in 1 sunny day with ≥400W, a fuel-powered outboard motor with up to 100A charging current, or a generator + 14.6V 20A charger in about 5 hours.
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.
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.
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.
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.
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.
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.
