Choosing the Correct Battery Type for Solar Panels

Solar Panels for lithium battery

In this blog I will break down the different battery types available to use with your Solar Panels. Lead acid batteries have large capacities and are often available in many places around Australia. A lot of people ask me "which battery should I use with solar panels?" I always recommend using sealed AGM lead acid batteries wherever possible and will describe in this blogs the benefits of using this type of battery with iTechworld portable solar panels.

Starter vs. lithium Batteries
Starter batteries are designed to deliver short, high-current bursts for starting a vehicle engine, and are designed to discharge only a very small part of their capacity. If you were to use a starter battery as a way of running your caravan/motor home/camper trailer it would corrode very quickly, the plates and the chemistry are designed to stay nearly 100% fully charged most of the time. They cannot handle the discharge and charge needed when running your RV on Solar Power.

For solar charging applications, I always recommend an iTechworld lithium battery. Cheap knock off batteries are available via eBay but come with very little warranty and fake specifications which means you can never be sure of what getting.

Typical car batteries can be used but will not be suitable long term. iTechworld lithium batteries are designed with larger capacity. They are designed to be charged and discharged by solar and can handle the strain of using most of its capacity.
