Gauge your performance
Accurate gauging products for any battery system
High accurate multiple-chemistry gauges for applications ranging from single-cell to multiple-cell battery packs, such as smartphones, notebook / laptops, power tools, vacuums, and energy storage systems (ESS). There are gauges equipped with integrated hardware protection and second-level protection for permanent failure. In addition, there are gauges with pack level gauging for higher voltage applications such as battery packs >15 series-cells. Our patented gauging algorithms aid the gauges into accurately measuring state of charge and state of health for a variety of chemistries such as li-ion, LiFePO4, and NiMH.
