Service life even slightly improves in case of partial charge instead of a full charge. This is a major advantage of Li-ion compared to lead-acid. The SuperPack batteries will cut-off the charge or discharge current when the maximum ratings are exceeded.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eEfficient\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eIn several applications (especially off-grid solar) energy efficiency can be of crucial importance. The round-trip energy efficiency (discharge from 100% to 0% and back to 100% charged) of the average lead-acid battery is 80%. The round-trip energy efficiency of a Li-ion battery is 92%.\u003c\/p\u003e \u003cp\u003eThe charge process of lead-acid batteries becomes particularly inefficient when the 80% state of charge has been reached resulting in efficiencies of 50% or even less in solar systems where several days of reserve energy are required (battery operating in 70% to 100% charged state).\u003c\/p\u003e \u003cp\u003eIn contrast a Li-ion battery will still achieve 90% efficiency even under shallow discharge conditions.\u003c\/p\u003e \u003cp id=\"QAO8H5U\"\u003e\u003cstrong\u003eCan be connected in parallel\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe batteries can be connected in parallel.
