lithium marine starting battery

Specifically designed to deliver high peak current for fast engine starting. 12V Lithium cranking battery offer many advantages over traditional lead-acid batteries, including light weight, higher energy density, longer life and faster charging.

Outboard Cranking Battery

Boat cranking battery provides the high peak current required to start a ship’s engine, it needs to provide high peak current for a short period to ensure that the engine can start quickly. As boats are subject to bumps and vibrations when moving on the water, Outboard Cranking Batteries are often designed to be vibration-resistant to ensure that they work reliably in harsh marine conditions. 


12V135Ah lithium cranking battery

Since boats are susceptible to wet conditions and waves, cranking LiFePO4 batteries have leak-proof technology to prevent battery liquid leakage. To ensure that the battery remains charged even when not in use for extended periods, the cranking LiFePO4 battery has a low self-discharge rate. Have a durable case and design to withstand the effects of harsh weather and marine conditions.
