Marine Series 12V 110Ah Lithium Battery with in-built DC DC Charger is constructed using the latest lithium iron phosphate cells. These prismatic cells are of the highest quality in a metal hard case. The battery has an inbuilt Battery Management System (BMS).

This lightweight battery has around double the usable capacity at up to a third of the weight of a lead-acid or AGM equivalent.

Designed to fit within the footprint of a standard N70 battery, a second battery compartment, or standard battery box for direct lead-acid replacement. The DCS model has an internal DC-DC charger to connect to a vehicle alternator or start battery.

The strong aluminium outer enclosure delivers a safe, lightweight, and powerful unit which is the perfect building block for next-generation battery systems.

Why Lithium?

Lithium batteries provide more usable capacity than lead acid batteries. Deep discharging does not affect the life of a lithium battery the way it does with lead acid batteries. You can use the battery longer before needing to recharge, without damage to the battery.

Cost Effective Over Life Cycle

When considering the usable capacity and lifespan of lithium batteries, they work out cheaper than lead acid. When you add the cost and inconvenience of refitting new lead-based batteries every few years the total cost of ownership over the long term is far better with lithium batteries.

Longer life

Lithium batteries are rated for 2,000 – 5,000 cycles and much more if used carefully, giving you several times the life expectancy of standard lead acid batteries


Lithium batteries allow you to pull far more amps out of the same size battery systems


Lithium batteries are less than half the weight of the equivalent lead acid battery.

Fast recharge

Lithium batteries charge more efficiently and don’t require as many stages during charging. Therefore, they will charge faster, and hold more of the energy from solar panels and other charging devices
