------------------------------------------------------------------------------------------------------------------------------------------------------------- Q&A Q1: Is it safe to use this to charge a 12V battery? Will it overcharge my battery?   A1: It is very safe, and there's no need to worry. Our controller has overcharge protection. It will automatically stop charging when the battery is full and resume charging and maintenance when the voltage drops.     Q2: Will this solar panel kit drain my battery?   A2: No, it does not drain the battery. The controller operates using the power generated by the solar panels.     Q3: What are the advantages of an MPPT controller compared to a PWM controller?   A3: An MPPT controller doesn't waste any of the power generated by the solar panels. For the same wattage, an MPPT controller charges faster and provides a higher charging current.     Q4: Which types of batteries can this solar panel system charge?   A4: AGM, LiFePO4, GEL (Select Gel Mode for your wet, gel, flooded, lead-acid, maintenance-free batteries)
