Gens Ace iMars D300 G-Tech Dual-Channel AC/DC Battery Charger – Black – GEA300WD300-AB

The Gens Ace iMars D300 G-Tech Charger combines dual-channel charging, AC/DC power options and smart battery recognition in a compact unit. With up to 300W total charging power on AC and 700W total on DC, it is a versatile choice for preparing batteries at home, at the track or at the flying field.

Two independently controlled outputs let you charge separate batteries with settings suited to each pack. The D300 supports Gens Ace G-Tech smart batteries as well as conventional supported batteries configured manually.

Dual-Channel Charging

Charge two batteries simultaneously using independent settings for each channel. This is useful when preparing multiple vehicle packs or charging batteries with different capacities and supported chemistries.

Each channel offers an adjustable charge current of 0.1–16A, subject to available input power, battery voltage and the battery’s permitted charge rate.

AC and DC Power Options

The built-in AC power supply accepts 100–240V mains input, providing convenient operation without a separate desktop power supply.

For DC operation, the charger accepts 7–30V input and offers up to 350W per channel. Reaching its maximum DC output requires an appropriately rated power source and suitable input wiring.

G-Tech Smart Battery Recognition

When connected to a compatible G-Tech battery, the charger identifies battery information through the smart balance connector and configures supported charging parameters automatically.

Conventional batteries are also supported, with manual selection of chemistry, cell count and charging settings.

Clear 2.4-Inch IPS Display

The 2.4-inch IPS LCD screen provides a clear view of charging information and operating menus. Its wide viewing angle makes it convenient to check progress while the charger sits on your workbench or pit table.

Charging and Battery Maintenance Modes

The D300 offers Charge, Discharge, Balance, Storage, External Discharge, SyncCharging and Digital Power Supply modes.

Storage mode prepares supported lithium batteries for periods between uses, while balance mode helps equalise individual cell voltages. External discharge and synchronised charging require suitable additional equipment or connections specified in the instructions.

Compact Design and Cooling

Measuring 145 × 76 × 62mm and weighing approximately 530g, the D300 is easy to transport with your RC equipment. Its cooling system manages heat during operation, while built-in protections monitor conditions including short circuits, overcurrent and overvoltage.
