The PH3059 high power density smart battery is ideal for use in uninterruptible power supply systems and low-current DC motors etc. It uses high power density Li Ion manganese cells to enable very high current delivery for short periods. To handle its higher operating voltage and higher discharge currents, it uses a new standard connector & requires a different charger to our regular “N-series” standard batteries. Its rugged construction rating reflects it application in mobile environments. Its sibling the PH2059 uses high capacity cells to maximize the energy stored within the rugged case.

The PH2059 and PH3059 smart Li ion batteries can be customized to meet unique specifications. Maybe you’re looking for a label change to display your corporate livery? Or a firmware modification to the smart battery data? Or perhaps you need a performance change for the batteries? Creating custom-hybrids of standard batteries is a part of Inspired Energy’s established expertise.

P-Series batteries use a high-current, 7-pin D-sub connector. They are more rugged than the N-Series batteries - some of them are IP65-rated - they also are optimized for using cells with low internal impedance which excel in low temperature and high discharge current applications. They require the use of a "PH" series charger.
N-Series batteries use a 5-blade standard battery connector. They are optimized for using high capacity cells for maximum runtime. They require the use of a "CH" series charger.
