Lithium batteries are ideal for camping, caravan, and RV adventures, providing a lightweight and effective power solution for your camping essentials. In this guide, we'll go through everything you need to know about lithium batteries, and the key factors to consider when choosing the best one for your needs. What is a Lithium Battery?
For camping trips where weight is a critical factor, like 4WD camping, opt for a lightweight lithium battery. The BLA Marine Performance 12V Lithium battery is an example known for its lightweight design, weighing only 3 KG. Cycle life involves the number of charge-discharge cycles a battery can endure.
As a general rule of thumb, for an overnight camping trip where you need to charge small devices, a 25 to 30Wh charger is enough. However, if you intend to use bigger items such as DSLR cameras or fans, a battery capacity of about 200 to 300Wh is enough.
If you plan on spending a decent amount of time camping without a mains hookup, you may want to invest in a camping power pack. These are essentially large lithium batteries which can store electricity and generate AC and/or DC power to power your electrical camping gear.
The best camping power packs can be trickle charged using solar panels and therefore allow you to essentially live off-grid for many days and weeks at a time if the sun is shining reasonably brightly. Of course you can also charge a power pack directly from the mains or your car battery if required.
The 12V equipment in a caravan or motorhome relies on a leisure battery. This important item is not normally supplied with a new caravan whereas most new motorhomes have one as standard. Batteries that are designed to start a vehicle are made differently from batteries specifically intended to run leisure appliances.
