12 V 100 Ah IP67 lithium battery with BMS – Crosseven

The Crosseven 12 V 100 Ah IP67 lithium battery with BMS is a service battery engineered for marine use, where reduced weight, water protection and reliable cell management are real-world requirements. Its IP67 waterproof construction makes it suitable for installation in damp areas exposed to spray, typical of technical compartments on board.

The integrated BMS (Battery Management System) continuously supervises cell status, protecting the battery from overcharge, deep discharge and overheating. Below freezing, the built‑in heating keeps the cells within operating range, avoiding the performance issues typical of lithium in cold environments. Bluetooth communication and a CAN port enable real‑time monitoring from a smartphone: state of charge, voltage, output current, temperature and cycle count are directly available to the user.

Compared to a lead‑acid battery of equivalent capacity, weight is reduced by 50–60%, a significant advantage on boats where weight distribution is part of the design. UN38.3 certification attests compliance with international tests for vibration, shock, short circuit and extreme temperatures required for transporting lithium batteries.

Main features

• Integrated BMS provides active protection of the cells against overcharge, deep discharge and abnormal temperatures, extending battery service life
• Built‑in heating keeps cells operational below zero, allowing use in cold seasons or harsh climates
• Bluetooth monitoring and CAN port allow real‑time readings via smartphone of state of charge, voltage, current, temperature and cycle count
• IP67 waterproof construction suitable for installations on board in areas subject to humidity, spray and condensation
• 50–60% weight reduction versus an equivalent lead‑acid battery, with direct benefits for trim and load on the vessel
• UN38.3 certified in accordance with international tests for vibration, shock, short circuit and extreme temperatures for lithium battery transport
