Marine energy · Nexus Pro™ Series
High-capacity marine power, engineered for the realities of marine installation.
Nexus Pro brings more usable energy into less space, with installation features designed around the realities of building and upgrading marine energy systems.
Marine power demands keep growing. Owners want to run more equipment for longer, while installers are often asked to fit a larger house bank into spaces that were already full. Nexus Pro™ was engineered to address both sides of that challenge: high usable energy and a battery designed around how marine systems are actually installed.
One Nexus Pro can replace four or more 8D-size AGM batteries while delivering more usable energy. That energy in a smaller footprint can simplify an installation, free valuable space and create room to expand a house bank. More usable energy in less space can reduce or eliminate generator use.
Designed around installation realities
Many companies make batteries for marine use. Few give enough thought to how those batteries will be installed and integrated into a complete marine energy system. Alternative mounting orientations can be the difference between a bank that fits and a bank that does not—and can make a major expansion possible in a space-constrained vessel.
Tiger Lithium put in the engineering work to account for those challenges from the start. Nexus Pro’s integrated mounting system supports top-up, side and vertical orientations without custom brackets or fixtures.
Three mounting orientations give installers more options for using available space.
An integrated, user-serviceable Class T fuse also keeps fuse serviceability with the battery and removes a separate fuse holder from the installation plan.
When a vessel has usable vertical space, an optional Tiger Lithium stacking kit supports stacks of up to four batteries. The arrangement can preserve deck space for other equipment while keeping a large bank organized.
Build the bank around the vessel
Nexus Pro is available in 12V 628Ah and 24V 314Ah models, and supports up to eight batteries in parallel in either configuration. That gives system designers room to build from a single high-capacity battery to a much larger house bank around a vessel’s power needs.
Two configurations. One scalable platform.
Both models share the same installation-focused approach and can scale into high-capacity marine house banks.
Straightforward setup for connected systems
Installers can select NMEA 2000 or Victron communication by installing the corresponding firmware over the air, aligning the battery with the vessel’s chosen system.
With Victron firmware and a compatible Cerbo GX, DVCC lets the Nexus Pro BMS actively manage charging and discharging across the connected Victron system. The BMS sends its current charge-voltage, charge-current and discharge-current limits to the Cerbo GX, which shares them with compatible Victron chargers and inverter/chargers. The system uses those limits to keep charging within what the battery can accept and discharging within what it can deliver, helping protect battery health and support long service life.
Built for the marine environment
Nexus Pro combines a marine-grade aluminum enclosure with an IP67 rating. An integrated power button and LED state-of-charge display make key battery functions easy to access, while the Sentinel-LNX™ app for iOS and Android adds connected monitoring. Each battery is backed by a 5+1 year non-prorated limited warranty.
UL 1973 and NMEA 2000 certifications are in progress; both are anticipated in Q1 2027.
