The FLEX12V is an innovative two-amp micro-controller for charging all 12V lead-acid batteries, including Wet, Gel, MF, EFB and AGM. This regulator uses pulse-width-modulation (PWM) for precision charge control and features a built-in recovery mode for recovering damaged and sulfated batteries. FLEX12V matches power with safety featuring built-in protection against reverse polarity, sparks, overcharge, over current, overheating, short circuit and open circuit. Its modular design allows you to plug-and-play with any NOCO XGrid Solar Panel.
