GYS Flash 4A 12V Intelligent Battery Charger

Motorcycles, jet-skis, go-karts, and small urban vehicles need precise battery management - not the blunt approach of a charger designed for larger lead-acid banks. The GYS Flash 4.12 is built specifically for 12V batteries from 1.2 to 70Ah, delivering a 7-step intelligent charge cycle that optimises for smaller capacity needs and charges in roughly half the time of a traditional charger.

The Flash 4.12 is compact, portable, and equipped with quick-connect waterproof connectors that make repeated attachment straightforward. It handles Start and Stop AGM batteries and includes a winter mode for optimal charging in cold conditions. Maintenance charging can continue indefinitely with the unit left connected, and Auto Restart ensures it resumes correctly after any power interruption - making it a reliable choice for seasonal storage of motorcycles, jet-skis, or lawnmowers.

Features

7-Step Intelligent Charging Curve - Tailored for small 12V batteries, optimising each phase of the charge cycle for capacity, longevity, and speed.
AGM and Winter Mode - Dedicated charge profile for Start and Stop AGM batteries and for charging in cold conditions below 5 degrees Celsius.
SOS Recovery - Recovers deeply discharged batteries down to 2V that conventional chargers cannot restart.
Waterproof Quick-Connect Connectors - Fast and secure attachment, suited to repeated use across multiple vehicles in a workshop or at home.
Cigarette Lighter Adaptor Compatible - Optional cable allows charging via the vehicle cigarette lighter socket without opening the bonnet.
IP65 Rated - Protected against dust and water ingress for reliable use in workshop and outdoor environments (not waterproof).
Auto Restart - Resumes charging with correct settings automatically after any power interruption.
Wall-Mountable - Can be fixed in a permanent position in a bay or storage area.
