Lithium-ion service batteries for Marine – Boat – Yachting

Lithium Iron phosphate technology provide a lot of benefits in terms of volume, weight and lifespan. These criteria are essential on a boat, sailing ship or a catamaran.

Lithium ion service batteries for Marine – Boat – Yachting are about twice lighter than classical AGM batteries. Also, they are 2 times smaller. They are undeniable assets for livable space, navigability and boats performance and other marine applications.

Note :

The choice of lithium ion service batteries is the most relevant if you have a lot of electronic devices on board. It can be navigation equipment, electronics or electric appliances.

Why moving on lithium ion service batteries (LiFePO4)?

For equal performance, a lithium ion battery for marine application PowerBrick® is more efficient, twice lighter and smaller. By comparison to lead-acid batteries, it represents a considerable space saving especially on board. To sum up, the energy density of a PowerBrick® battery lithium (service battery) is 4 times higher than equivalent lead battery. In addition, a lithium Iron phosphate battery last around 10 years according to the use.

Besides, lithium ion service batteries have nor memory effect, nor maintenance, nor possibility of leak, neither gas emission.

The battery is the heart of the boat

Modern boats are more and more equipped with electronic devices which require constant power. A power cut on board can be a critical event during a navigation.

First of all, if you replace a lead-acid battery by a service lithium ion battery for marine applications, you need 50% less capacity in Ah to gey the same autonomy. Or you can take the same capacity and you will get twice more capacity.

By replacing your lead-acid battery by a lithium battery is quite simple :

  • Select voltage (12V, 24V, up to 48V) by assembling batteries in series
  • Select battery capacity : We advise to replace a Lead acid battery by half capacity Lithium battery: a 12V 110Ah AGM battery can be replaced by a PowerBrick 12V 55Ah
  • Set up branches in parallel if you need higher capacity and autonomy

Key points regarding lithium Ion batteries for boats, yachts and other marine applications:

Safety

PowerBrick® is a very safe battery with a built-in Battery Management System (BMS). The BMS automatically balances cells during charging. It also monitors cell voltage and temperature in real time. The Battery Management Systems also protects from any misuse or mishandling (deep discharge, unsuitable charge voltage, etc.) to ensure the battery an optimal life.
Because PowerBrick has been designed with safety in mind, the lithium cell technology used in this product (Lithium Iron Phosphate) make it almost insensitive to thermal runaway and ignition

Battery Management System by PowerTech Systems

Lithium Iron Phosphate (LiFePO4) batteries are environmentally friendly. They do not contain heavy metals (lead), nor rare earth (Cobalt).
The high efficiency of batteries (96%!) ensures few energy losses in use, and a better energy yield.

Tip :

These batteries can work vertically, but also lying on it’s side without any concern. Lithium Iron Phosphate batteries can be fully discharged (Deep Discharge) without any damage thanks to the embedded electronics hosted inside the battery.
