GYSFLASH 101.12 CNT FV – 100A Battery Charger & Support Unit – 026988

The GYSFLASH 101.12 CNT FV is a professional, high-power 100A 12V battery charger and battery support unit, designed for modern vehicle workshops, diagnostic technicians, dealerships and vehicle programming applications.

This 026988 version is supplied with 5 metre, 16 mm² charging cables, providing excellent reach around the workshop and making it particularly suitable for diagnostic bays and vehicle programming.

Using advanced inverter technology, the GYSFLASH 101.12 CNT can maintain a perfectly stabilised 12V supply during vehicle diagnostics, while also providing intelligent charging for both lead-acid and lithium (LFP) batteries.

Four Operating Modes

Charging Mode
Charges 12V lead-acid and lithium (LFP) batteries from 5Ah up to 1,200Ah.

Diagnostic / Power Supply Mode
Provides up to 100A of battery support to maintain vehicle voltage during diagnostics, ECU programming and other workshop procedures.

Showroom Mode
Compensates for electrical consumption when vehicle accessories are being demonstrated, helping maintain battery condition on showroom vehicles.

Tester Mode
Allows checking of the battery condition, starting system (starter and battery) and vehicle alternator.

100% Connected & Customisable

USB connectivity allows charging modes and profiles to be added, deleted or modified.

Predefined configuration files can be imported for different charging applications, while charging history and data can be exported via USB for analysis using spreadsheet software.

The Smart Module Connector (SMC) also allows compatible additional modules such as a printer or barcode reader to be connected.
