Tuotetunnus (SKU): acb54 Osastot: ,

Compact and exceptionally durable, our Lithium Iron Phosphate (LFP) batteries are the ideal choice for deep-cycle applications—especially when paired with solar systems.
Compared to AGM and traditional lead-acid batteries, LFP technology offers dramatically higher charging efficiency. An integrated Battery Management System (BMS) protects the battery from misuse, ensuring long lifespan and reliable performance.

With a cycle life that’s an order of magnitude greater than other chemistries, LFP batteries are unquestionably the most cost-effective and future-proof energy storage solution available today.

Technical Details

Our batteries are engineered to precise specifications and built using premium components sourced from industry-leading suppliers of battery cells and control systems. Paired with our custom-developed application software, users gain an intuitive and powerful interface for real-time monitoring and control.

With both Bluetooth and CAN bus communication options, the battery seamlessly integrates into any Energy Storage System (ESS)—whether off-grid or on-grid. While optimized for Victron installations, our batteries are fully compatible with any charging system that supports the correct voltage profile and LFP chemistry.

To maximize strength, efficiency, and internal layout precision, each battery enclosure is 3D-printed from high-grade engineering polycarbonate. This advanced material offers excellent thermal and mechanical performance, a high melting point of 230°C, and a UL94-V0 flame-retardant rating for enhanced safety. In order to maximise the structural strength, the battery is seated in 3mm aluminum cradle that can be mounted to brackets and secured compactly in car or yacht.

For flexible installation requirements, battery terminals can be configured as M8 brass sockets or ESS Safe Connectors, available in 160 A or 200 A variants depending on cable size and system demands.

Our batteries are also fitted with electric heating pads. LiFePO4 chemistry can be discharged with good efficiency even in extremely cold temperattures, but charging the battery is different. To charge the battery, the cell temperature has to be close to 0°C degrees. To allow the operation in extreme conditions, our batteries are fitted with electrical heating pads that allow heating of the cell when charger is connected.
