📊 Specifications

🧭 What to know before purchase

• Lithium batteries must always be considered in conjunction with proper BMS, charger, and system protection.
• Check voltage, capacity, physical space, and whether the installation is already dimensioned for lithium.
• If you are building a complete Victron system, compatibility with BMS and monitoring is an important part of the choice.

🔧 Installation

Batteries should be mounted securely and with proper strain relief, ventilation, and cable sizing. Check polarity, terminal type, space conditions, and ensure that the charger/inverter/regulator is set up for the correct battery type.

💡 Tip from SejlStrøm: The right battery is not chosen by Ah alone – weight, space, chemistry, charge profile, and the overall system architecture also matter significantly in practice.
