Lithium Battery Habitation

Lithium Batteries Caravan or Motorhome

Leisure Batteries come in many different shapes and sizes. It is no wonder we have difficulty choosing one.

If you are in the South West, we are happy to help solve your battery needs, whatever your battery needs.

Why choose a Lithium Battery?

These are the main reasons:

  • Weight Saving:

Lithium batteries, although the same size, weigh half as much as your lead-acid leisure batteries. They have also been designed to supply more amps for longer meaning you get more power!

  • Fitting:

Lithium batteries can be fitted on their side, space is not usually an issue.

  • Longer Lasting:

The ultimate bonus of a Lithium battery is how you can discharge it to as little as 20% and it will not affect the batteries lifespan. This is dissimilar to a Lead battery, as discharging it as low as 50% can cause damage.

Lithium batteries charge will last longer, and if looked after will last you longer.

What is important when choosing a leisure battery?

Physical size is important, double check the battery location, your new battery will need to fit into the space provided in your caravan or motorhome.

What is a Leisure Batteries Capacity & Usage?

Amp Hours (Ah), this is the rating a battery is given, which indicates how long your battery will last, based on your power consumption. In theory a 100 Ah will deliver 1 Amp for 100 Hours.

Cycle Times (CT). This is how many times your battery can run low and be recharged. Think of this as your Return on Investment (ROI), how many recharges will you get for the purchase price of the battery.

Changing. Leisure Batteries are usually charge in one of three ways:

  1. From the engine’s alternator when you are driving.
  2. From a charger connected to a 230v mains hook-up.
  3. From solar panels.

Leisure Batteries discharge (run flat) through using on-board 12v devices inside lights is the obvious example, but don’t forget, most appliances (fridge, heater, cooker) need 12v to run the PCB control panel and ignite the LPG.

Where should my leisure battery be stored?

A key factor often not explained to owners is gases given off during the charging process. This is important when the battery is located inside the habitation area of your caravan or motorhome. Your leisure battery should be in a sealed unit, which is vented to the outside. If it is not vented externally, hazards include:

  1. Risk of explosion / fire, gases are flammable.
  2. Risk to your health, gases are poisonous.

 

To compare, here are three leisure battery types, spec. & prices are approx. batteries are based on performance of a 100Ah size or equivalent:

    Gives off gas when being recharged.
    CT 150
    Weight 23 KG (Heaviest)
    Operating Temp -5>45 °C
    Depth of Discharge 50%
    Circa. £130.
    ROI £0.87 per charge (Least cost effective)
  2. AGM.
    Gives off minimal gas when being charged.
    CT 300
    Weight 18 KG
    Operating Temp -15>45 °C
    Depth of Discharge 50%
    Circa. £195
    ROI £0.65 per charge
  3. Lithium. Best option.
    CT 5,000
    Weight 14 KG (Lightest)
    Operating Temp -20>60 °C
    Depth of Discharge 100%
    Circa. £1050
    ROI £0.21 per charge (Most cost effective)

At Bristol Caravans, fitting is approx. £32.00 based on straight swap, no modifications, or additional fixings.
