What is the TommaTech ABS+PC Case 12.8V-100Ah Marine Battery?

TommaTech ABS+PC Case 12.8V-100Ah Marine Battery is a rechargeable lithium iron phosphate battery used in boats, caravans and similar mobile systems. Multiplying the 12.8V and 100Ah values gives a nominal energy of approximately 1.28 kWh. It has an ABS housing and is a model designed to replace a VRLA battery.

Key technical features

  • Nominal voltage / capacity: 12.8V / 100Ah
  • Case: ABS
  • Cell certificates: ROHS, IEC62619, UL1973, UL9540A
  • ABS housing; can be used in place of a VRLA battery
  • IP65, maintenance-free
  • Protections: overvoltage, undervoltage, overcurrent, over- and under-temperature, short circuit

Which projects is it suited for?

It is suited for cruising boats, sailboats, caravans, fishing boats, country houses and small off-grid systems. It can be used in place of a lead-acid battery in setups that supply 12/24V loads such as an electric motor, navigation electronics, lighting and a refrigerator. It can also be part of mobile systems charged by a solar panel.

When choosing, daily energy consumption, the inverter's battery input and the desired backup time should be evaluated together. Cable cross-section, DC fuse and ventilation of the compartment are also part of system safety; Solar Nexo completes these checks during the site survey before installation.

Use in Antalya and Solar Nexo support

Antalya's marinas and bays offer a salty, humid environment. The IP65 waterproof case provides protection under these conditions; even so, the battery should be mounted in a secured, ventilated compartment on the boat, away from areas that get splashed.

From supply of the product through project design, installation, commissioning and subsequent technical support, Solar Nexo handles the whole process in Antalya from a single source. You can download the product datasheet from this page.
