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

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

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

Two Independent Charging Channels

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

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

AC and DC Power Options

The built-in AC power supply accepts 100–240V mains input, making the D300 convenient for workbench use without a separate power supply.

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

G-Tech Smart Charging

With a compatible G-Tech battery connected, the D300 identifies battery information through the smart balance connection and configures supported charging parameters automatically.

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

Clear 2.4-Inch IPS Display

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

Battery Charging and Maintenance Functions

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 the equipment and connections specified in the charger’s instructions.

Compact Design with Managed Cooling

Measuring 145 × 76 × 62mm and weighing approximately 530g, the charger fits easily into your RC equipment bag. Its cooling system manages heat during operation, while built-in protections monitor conditions including short circuits, overcurrent and overvoltage.
