Frequently Asked Questions

Do you still have questions?
You can find more information in our frequently asked questions.

F: What applications is the LiThink 12V 165Ah dual-purpose battery suitable for?

A: It combines high starting power with long-lasting energy supply. The battery is suitable for starting compatible petrol outboard engines as well as powering trolling motors, fish finders, navigation devices, pumps, lighting, cool boxes, and other 12V onboard electronics.

F: Can the battery start a gasoline outboard motor?

A: Yes. It delivers 1800A HCA, 1600A MCA, and 1500A CCA at −10°C and is designed for compatible gasoline outboard engines up to 300 hp. Before installation, the engine's starting current requirements and the charging system's compatibility must be checked.

F: What does “Dual Purpose” mean for this battery?

A: Dual Purpose means that a battery serves two functions: it provides high current at short notice to start an outboard motor while also delivering sustained power for trolling motors and electrical devices on board.

F: What continuous output does the 200A Smart BMS offer?

A: The 200A Smart BMS supports up to 200A continuous charging and discharging current, as well as continuous output power of up to 2560W. This also makes the battery suitable for high-power 12V devices.

F: What surge current output does the battery provide?

A: For short-term peak loads, 700A is available for 1 second, 500A for 3 seconds, 400A for 5 seconds, and 300A for 10 seconds. This power reserve supports motor starts and other applications that briefly require high current.
