Slimline 12v 100Ah Lithium Battery with built-in 20A DC-DC Charger is constructed using the latest lithium-ion phosphate cells. These prismatic cells are of the highest quality in a metal hard case. The battery has an inbuilt Battery Management System (BMS).

At just 11kg, the unique slimline shape makes it the perfect battery for installations where space is a premium. Slide it behind a seat, install in your canopy, or under a false floor.

The 100Ah Lithium Battery with built-in 20A DC-DC Charger provides up to 100A of continuous discharge or charge and can be stacked in parallel to increase amp hour storage capacity. Charge and discharge via the grey Anderson plug and charge from a DC source via the blue Anderson plug.

The strong aluminum outer enclosure delivers a safe, lightweight, and powerful unit.

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. Lithium batteries can be up to a third of the weight of the equivalent lead acid AGM battery. This is an important consideration for anybody who is mobile.

A 100Ah AGM deep cycle battery can be up to 38kg in weight, whereas the same size lithium battery can be less than 12kg in weight!

That means you can at least double or even triple the stored battery capacity on a RV, or alternatively use the reduction in battery weight to bring more water, or food or luggage on your trip.

Reducing weight in a RV helps to keep you under the tare weight, reduces aerodynamic drag which improves fuel efficiency while on the road.
