Why choose lithium?
Lithium batteries have a much longer usable amp time compared to lead acid batteries. Unlike lead-acid lithium batteries that can be deeply discharged without affecting cycle life. This means you can use the battery for a longer period of time before recharging. In contrast, AGM batteries are generally recommended to be discharged to only 50% of their capacity to maximize their cycle life, while lithium can typically be discharged to 80-90% of capacity.
