Our Background

Headquartered in Piney Flats, Tennessee, Diversified Power International designs and manufactures smart battery chargers, battery-related power systems, power converters, and solar-powered energy systems. Launched in 1997 by a small group of engineers whose backgrounds spanned many years in the lead-acid battery business, DPI initially manufactured battery chargers for the motive power industry (fork lifts, pallet movers, golf carts, etc.). The founders’ combined experience was soon brought to bear on developing energy products that surpassed the meager performance of retail-type products. Today, DPI provides microprocessor-based design and manufacturing solutions to most all industries including retail, material handling, medical/healthcare, military, industrial, automotive, and more. Our products have proven to reduce battery gassing and fluid loss while reducing battery heating and consuming less power. Many years of research and in-house testing of charging and discharging battery packs have resulted in DPI chargers increasing battery life, reducing operating costs, and operating more efficiently.

Our Operations

DPI’s primary goal is to satisfy customers’ energy needs at an exceptional value. To achieve this, DPI emphasizes continual operational and product improvement, providing its employees with the proper tools, technologies, and on-going training required to consistently deliver the highest-quality products possible. This approach has resulted in an environment where DPI employees take pride and ownership in their work, and, in turn, a selection of reliable energy systems that push the envelope of industry innovation.

DPI’s “do it right the first time” dedication to quality workmanship means maintaining focus on reducing process variability and continually improving our Quality Management System, which ensures compliance with all parts (with the exception of "Service" as stated within clause 7 of the standard) of ANSI/ISO/ASQ Q9001-2000. This quality system provides the structure to consistently deliver products that meet customer and applicable regulatory requirements. To learn more about DPI’s Quality Management System, see ISO Certificate, e-mail us at support@dpipower.com, or call 800-334-5091. 

Our Technology

While most retail battery chargers are pre-programmed with general-purpose software, which results in either an overcharge or undercharge of the battery, DPI’s technology involves manufacturing each battery charger with a microprocessor containing custom software developed in-house by our engineering team. This microprocessor contains sophisticated mathematic calculations/algorithms for determining each battery’s appropriate recharge requirement. DPI chargers deliver a 100% recharging capacity as opposed to the usually 40% to 70% found with most chargers.

Our Products and Services

DPI offers a standard inventory of high-volume, cost-targeted, off-the-shelf products, as well as custom designs for lead-acid batteries, nickel metal hydride, nickel cadmium, and lithium-ion batteries. We also offer custom electronics, custom software, system enclosures, and manufacturing and testing services.
