High-Performance 30A 12V Battery Charger and Support Unit for Lead-Acid & Lithium Batteries
The GYSFLASH 30.12 PL is a powerful 12V automatic charger and power supply unit designed for professional use in workshops, showrooms, and vehicle diagnostics. Delivering up to 30A continuous current at 100% duty cycle, it supports both Lead-Acid (Gel, AGM, EFB, Liquid, Calcium) and Lithium-Iron Phosphate (LiFePO₄) batteries from 7 Ah to 375 Ah.
It offers two dedicated charging programs with 7-step (Lead) and 8-step (Lithium) charging curves, ensuring optimal performance and extended battery life. Selectable output modes (7 A, 15 A, or 30 A) allow precise control, while Showroom/Diag mode maintains vehicle systems during display or diagnostics.
The integrated temperature sensor, Auto Restart feature, and deep discharge recovery make the GYSFLASH 30.12 PL a reliable, safe, and efficient charger for professional maintenance and support operations.
