    "A word of advice? The first step is to throw away everything you thought you knew about battery monitoring!"

    -CFE Engineer
    Operations manager

    “Accurate and real-time battery data is always at my fingertips; at the site, at my office, at home, or on the road.”

    -Operations manager

    “Internal resistance data for each battery becomes obviously useful.”

    Substation Engineer

    “Connection resistance data exposes any issues with corrosion and installation or service quality. My Job is not done until this bar chart looks perfect. It literally directs me to go clean and tighten the posts of cells #8 and #9.”
