A catamaran is a comfortable and safe watercraft used both for leisure cruising and for transporting passengers or fishing. To ensure it operates reliably, it must be properly equipped. One of the most important components is the LiFePO₄ battery—the main power source for the vessel and all onboard systems.
Batteries for catamarans must be correctly selected to match the specific vessel, taking into account its size and the energy requirements of all installed devices. A typical catamaran setup includes two batteries: a starter battery for the engine—chosen according to the engine type—and a service battery to power onboard systems based on the total energy demand.
We offer the best LiFePO₄ batteries for catamarans, manufactured by Kon-TEC using advanced lithium iron phosphate technology. These batteries offer outstanding performance, with a long cycle life and high durability—even under deep discharge. They maintain consistent capacity throughout their service life, including under increased current loads. Additionally, they are significantly lighter than traditional batteries and are exceptionally resistant to harsh environmental conditions.
