TORQEEDO Power 24-3500 High-Performance Lithium Battery / set of 2

For Frequent Drivers and Water Conservation Areas

Built with superior intelligence and protection circuitry, this superior quality, high-performance battery provides 3,507 Wh (139.2Ah) from just 53.6lb. It requires a charger (sold separately). You can plug and play with the Cruise’s onboard computer. Just plug the cable in and you’re done. No major setup requirements.

A water sensor lets you know when the battery is submerged and automatically switches the voltage off at the poles. This avoids potential formation of detonating gas, a major safety benefit, in case water gets into the boat. There is double protection with isolatable poles for safe transport, installation and preventing unintentional discharge.

The battery design involves safety cells offering multiple protection. Individual battery cells have welded steel cylinders equipped with multiple hardware safety mechanisms. The battery management system (BMS) provides additional protection and balancing functions for a long battery life. All safety functions have redundant backup due to one-fault safety.

Features:

• Up to 70% less battery weight than AGM or gel batteries
• Plug and play allow for easy installation and activation
• Integrated information system communicates with the Cruise on-board computer
• Battery management system with one-fault safety
• Completely waterproof housing and plug connections (IP 67)
• Venting balances differences in temperature and pressure without waterproof qualities
• Water sensor recognizes when the battery is submerged and automatically switches the voltage off at poles
• Water sensor prevents potential formation of electrolytic gas in the event water gets into boat

1: Plug & play with the Cruise on-board computer: plug the cable in, “electronic handshake”, finished.

2: Waterproof venting: balances differences in temperature and pressure without limiting waterproof qualities.

3: Water sensor protection: recognises when the battery is submerged and automatically switches the voltage off at the poles. Prevents the potential formation of electrolytic gas in the event that water gets into the boat.

4: Mature intelligent battery management system (BMS): the BMS provides additional protective and balancing functions for long battery life. All safety functions have redundant backup thanks to one-fault safety.

5: High-performance lithium battery cells: Top quality, exclusively from fully automated Japanese production.

6: Double protection – isolatable poles: for safe transport and installation And preventing unintentional discharging when stored for long periods.
