About Us

Charlie Mellone – Founder

Charlie has over 40 years experience in electronics systems, hardware and software development. Charlie found his passion in 2008 when he converted a 1993 Nissan 240sx to electric. Unimpressed by the performance of the 18 Lead-Acid batteries, a Lithium-based pack was absolutely necessary. With no viable battery management systems available, he designed and built version 1 of the Vintage Voltage BMS.
