The GYSflash is made in France and is a premium professional quality charger providing fully automatic intelligent 7amp, 12v charging for lead-acid batteries (flooded, MF, gel and AGM and Calcium types) which are used in motorhomes and other vehicles for leisure and starter batteries.
It is powerful, compact and waterproof (IP65) and is recommended for heavier charging of batteries from 1.2Ah up to 130Ah. It can also be used for even larger battery sizes up to 230Ah but only for maintenance of batteries which are already well charged - otherwise charging time would be excessive.
It ensures an automatic charge up to 100% without supervision. Ideal for cars, vans, boats, trucks, lawn mowers, motorbikes.
The GYSflash 7A will start up and begin charging successfully even when the battery has been severely discharged down to only 1v making it possible to recover such batteries in some circumstances.
It can perform automatic recovery of deeply discharged and sulphated batteries.
Examples of use and features:
Charger for van / car / bike 12V battery - maintenance/wintering - battery recovery for sulphated 12V batteries.
Protection for on-board electronics of the vehicle.
Protection against short circuits / polarity reversals / over-voltage / Anti-spark system prevents sparking when connecting.
