The Topband B-Series are high quality lithium batteries with a 4000+ cycle life that are perfect as drop-in replacements for lead-acid batteries in leisure, marine, solar, power backup, and other deep cycle applications. A built in BMS ensures comprehensive safety and Bluetooth functionality allows connection to the battery via the TBEnergy App where you can view real time SoC, charge/discharge current, charge time remaining, battery temperature, warnings, error logs and more.
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.
