Lithium Iron Phosphate batteries are one of the safest types of batteries available on the market. As explained in our information ‘About Lithium Ion Batteries’, LiFePO4 batteries are remarkably safe.
Due to the chemical and thermal composition of the batteries, they do not overheat, nor will they explode or catch-fire if subjected to hazardous conditions such as collisions or short-circuiting. Due to the impeccable safety reputation, they are fast becoming the battery of choice on the market - a favorite with manufacturers and enthusiasts alike.
Will installing a lithium battery affect my vehicle or boat’s warranty?
Changing a lead acid battery, or any other variety of battery, for a LiFePO4 battery should not affect the warranty as long as it’s installed, and used correctly, as per the manufacturer's instructions.
How do I choose which lithium battery to install?
Before buying and installing a lithium battery, you need to fully understand what you require from your battery. Ask yourself the following questions;
- your overall budget
- will you be using a solar panel inverter
- how much power you will be using on your travels (total kilowatt hours)
- how much time you have to dedicate to maintenance of the battery
- how frequently you will be off-grid
- whether environmental factors play a part in your purchase decision and,
- if vehicle/ boat payload/weight is also a consideration for you.
You will need to work out what your total daily usage is likely to be in total kilowatt hours.
You’ll also need to consider a few other factors such as how you’re going to keep your battery charged, and where you are going to install it.
What is an inverter and will I need one?
Your battery is ideal for running all of the 12v appliances, however, when you need to use a 230V appliance but you only have 12V or 24V available in your vehicle or boat, you will need an inverter. Many people install lithium batteries specifically to run appliances such as coffee machines, hair dryers, and ovens.
You can use an inverter to change 12v DC (or 24v) to 120v AC. You’ll need an inverter if you want to run 120V appliances when no mains hook-up is available. Choosing the correct inverter is critical. If you get it wrong, it could damage your precious electronics and potentially catch fire. We suggest doing some research around this topic and picking the correct inverter to suit your needs and requirements.
What are the charging voltages for lithium batteries?
The charging requirements of lithium batteries are different to that of lead acid batteries. You should use a dedicated lithium iron phosphate (LiFePO4) battery charger, charged at a constant voltage of no more than 14.4V, with recommended 14.4V bulk and 14.4V absorption. Typically, charging at a lower voltage (14.3v) will do no harm, and may possibly extend the life of the battery, but do not charge at a higher than stipulated voltage.
Charging at the correct voltage will ensure you maximize the lifespan of the battery. Never charge your battery if the temperature of the unit is below 0°C.
How are LiFePO4 batteries affected by temperature?
The performance of LiFePO4 batteries is significantly impacted by temperature. For many batteries, the amp hour rating stated on them is based on a nominal temperature of 25°C, with each degree lower causing around a 1% drop in performance.
If the temperature of the battery reaches 0°C, you must not charge the battery from the engine, a mains hook-up, a solar panel, or any other charging source.
The Epoch Batteries trolling products have built-in heaters as standard, enabling them to be charged when the ambient temperature is as low as -20°C.
