Frequently Asked Questions
Can the GYSFLASH 30.12 PL charge Lithium batteries?
Yes — it supports Lithium Iron Phosphate (LiFePO4) batteries from 7 to 375Ah using an 8-step automatic charging curve and EBS cell balancing technology.
What is SOS Recovery?
SOS Recovery allows the charger to detect and recover deeply discharged batteries that have fallen below the threshold standard chargers can detect, preventing unnecessary battery replacement.
What is the UVP Wake-up function?
UVP Wake-up reactivates batteries that have entered protection mode following deep discharge, restoring them to a chargeable state.
Is it suitable for showroom or demonstration use?
Yes — Showroom mode delivers 30A current compensation to power vehicle electrical systems during demonstrations without drawing from the battery.
