The Topband S-Series are ideal entry level lithium batteries, offering an optimum mix of cost versus performance in a high quality package. Their standard design is mature and stable, making them perfect as drop-in replacements for lead-acid batteries in leisure, marine, solar, power backup, and other deep cycle applications. A built in BMS with frost protection ensures comprehensive safety and 2500+ cycles provides a long service life.

Lithium Iron Phosphate (LiFePO4) technology is fast becoming the new standard in deep-cycle applications with superior cycle life, useable capacity and charge/discharge rates, along with a much lower weight and very low self discharge.
