FAQs - Lithium Batteries

How are Lithium batteries constructed?

Unlike VRLA (Valve Regulated Lead Acid) batteries, or traditional flooded wet cell batteries, Lithium batteries are classified as “dry” batteries as they do not generate power from a liquid solution and they do not produce gas.

Instead, power is generated by the movement of Lithium ions between the negative electrode and the positive electrode. The positive electrode is made from a chemical compound called Lithium Iron Phosphate (LiFePO4). The negative electrode is generally made from carbon (graphite).

What is a Battery Management System?

An important component of any high quality Lithium battery is the Battery Management System (BMS). This is a sophisticated instrument which sits inside the battery and ensures each individual battery cell is charged and discharged equally.

When a single Lithium cell is fully charged, the voltage rises suddenly and can reach dangerous levels very quickly. If this happens in only one cell, that cell can reach dangerous voltages before the total pack voltage is high enough to register as fully charged. To prevent this from occurring, the BMS balances the cells to ensure they all charge and discharge equally as well as preventing them from over-discharging.

Cheap and inferior Lithium batteries often do not contain a sufficient BMS and are considered to be unsafe to use as they are prone to exploding or catching fire. Additionally, if you over-charge or over-discharge a Lithium battery without an adequate BMS, you will potentially damage the cells beyond repair.

A high quality Lithium battery with a sophisticated BMS will automatically disconnect loads if the voltage goes too low, and disconnect chargers if the voltage goes too high.

What are the benefits of using Lithium batteries?

Lithium batteries have greater cycle life than VRLA batteries and can be discharged to a deeper depth of discharge without affecting battery life. This results in the Lithium equivalent battery to a VRLA battery having a greater useable power.

Lithium technology has the capability to efficiently provide power in high energy demanding applications and will maintain their voltage throughout nearly the entire discharge curve.

Additionally, Lithium Phosphate batteries are on average three times lighter in weight than VRLA batteries and have been proven to cope with ambient temperatures of up to 60 degrees Celsius. Along with this, Lithium Phosphate batteries have a greater energy density, meaning you can get a larger capacity battery into the same dimensions of a VRLA battery.

Finally, Lithium batteries are able to be designed and manufactured to any footprint. They can be literally reshaped to fit into any existing cavity or around specific fittings. The battery cells can be packed to be long and thin or short and fat.
