GYSFLASH 125.12 CNT FV charger – 12 V 120 A for lead-acid and LFP batteries, USB (5 m cables)

GYSFLASH 125.12 CNT FV – Professional 12 V Charger

The GYSFLASH 125.12 CNT FV is a high-performance inverter charger designed for professional use in workshops, automotive service centers, and showrooms. With a maximum continuous charging current of 120 A at 25°C, it ensures optimal battery voltage stabilization during diagnostics and charging. The device is fully configurable via USB, allowing charging profiles to be tailored to the requirements of the most advanced vehicles on the market.

Four Operating Modes

1. Charging
   Charging of 12 V lead-acid batteries (gel, AGM, PbCa) and lithium iron phosphate (LFP) batteries, with capacities ranging from 20 to 1500 Ah.
2. Diagnostics
   Voltage stabilization and battery support during vehicle diagnostic phases, with current up to 120 A—ideal for service workshops.
3. Showroom
   Provides continuous power while using electrical accessories in a display vehicle, while simultaneously managing optimal battery charging.
4. Tester
   Ability to check battery voltage, the condition of the starting system (starter + battery), and the vehicle’s alternator performance.

Fully Connected and Configurable

• Add, remove, and modify operating modes and charging profiles via USB.
• Import ready-made configuration files tailored to workshop needs.
• Download charging history and data to a USB flash drive for analysis in a spreadsheet.
• Option to connect additional modules (printer, barcode reader) via the dedicated SMC (Smart Module Connector) port.

Automatic Charging – Extends Battery Life

• Specially programmed charging curves: 8 stages for lead-acid batteries and 9 stages for LFP batteries, without the need for supervision.
• Automatic recovery function for deeply discharged batteries (>2 V).
• Auto-Detect charger function – charging starts automatically once the battery is connected.
• Auto-Restart function – resumes charging after a power outage, with memory of settings.
• Ability to save up to 12 charging profiles, including an “Easy” profile for simple charging of all lead-acid batteries.

Technologies and Advanced Features

• FV Flexible Voltage – charger operates with a supply voltage range of 85–265 V.
• Cable monitoring and calibration, protection against improper use.
• Battery and vehicle electronics protection: safeguards against short circuits, reverse polarity, and overcharging; anti-spark system.
• Replaceable fuse protecting against incorrect use.
• Temperature sensor preventing electronic overheating.

Ergonomics and Durability

• Robust housing with built-in shock and vibration absorbers.
• IP40 protection rating – protection against objects larger than 1 mm.
• Low-profile design (13 cm height) allows easy placement under a vehicle.

Application

Ideal for automotive workshops, diagnostic service centers, and car showrooms where efficient, stable, and safe battery charging and voltage support during vehicle testing and repairs are essential.
