Gens Ace iMars D300 Plus G-Tech Dual Channel AC/DC Smart Charger with Bluetooth – Black – GEA300WPLUS-UB

The Gens Ace iMars D300 Plus is a powerful dual-channel AC/DC smart charger designed for R/C enthusiasts who want fast charging, easy battery management and modern smartphone connectivity. This GEA300WPLUS-UB version comes finished in Black and combines two independent charging channels with G-Tech smart battery support and Bluetooth app control.

With a built-in AC power supply, the D300 Plus can deliver up to 300W total charging power when connected directly to mains power. When powered from a suitable external DC source, output increases dramatically to 350W per channel – up to 700W combined.

Dual Independent Charging Channels

The D300 Plus features two independent charging channels, allowing you to charge two batteries simultaneously.

Each channel can provide up to 16A charging current, making the charger suitable for everything from smaller R/C packs through to larger high-capacity batteries used in 1/8 scale cars, boats and aircraft.

The charger intelligently distributes its available power when operating from AC, while a suitable high-output DC power supply unlocks the charger's maximum 350W-per-channel capability.

Bluetooth App Control

A major feature of the D300 Plus is integrated Bluetooth connectivity.

Using the Gens Ace app, you can remotely control and monitor the charger from a compatible smartphone. The app provides access to real-time operating information and historical charging records, giving you a convenient way to monitor your batteries and charging sessions.

This makes the D300 Plus particularly useful for racers and enthusiasts who regularly manage several batteries and want more information than a conventional charger can provide.

G-Tech Smart Battery System

The D300 Plus is fully compatible with the Gens Ace G-Tech Smart Battery system.

Connect a compatible G-Tech battery and the charger can automatically recognise the battery type and appropriate parameters, greatly simplifying setup and reducing the chance of entering incorrect charging information.

Simply plug in a compatible G-Tech battery and the smart system handles much of the configuration automatically.

Importantly, you aren't restricted to G-Tech batteries. Conventional non-G-Tech batteries can also be charged, with the appropriate battery parameters entered manually.

Wide Battery Compatibility

The iMars D300 Plus is designed to handle most of the battery chemistries commonly encountered in the R/C hobby.

It supports LiPo, LiHV and LiFe batteries from 1S to 6S, along with NiMH and NiCd packs from 1 to 16 cells.

This versatility makes one D300 Plus suitable for a wide range of applications including R/C cars, trucks, crawlers, boats and aircraft.

Multiple Battery Management Functions

The D300 Plus provides considerably more functionality than simply charging a battery.

Seven operating functions are available, including Charge, Discharge, Storage, Balance, 2-in-1 Fast Charge, External Discharge and Digital Power.

The Storage function is particularly useful for LiPo batteries. Instead of leaving a pack fully charged when it won't be used for an extended period, the charger can bring it to an appropriate storage voltage.

2.4-Inch IPS Display

A clear 2.4-inch IPS LCD display provides easy access to battery information, charging parameters and operating status.

All normal charger functions can be controlled directly from the unit, so using the smartphone app isn't necessary every time you want to charge a battery.

Eight-Level Protection System

Gens Ace has incorporated an extensive eight-level protection system into the D300 Plus.

Protection includes:

• Overheating protection
• Current limiting protection
• Over-voltage protection
• Wire-break protection
• Reverse-polarity protection
• Short-circuit protection
• Cell-count mismatch alert
• Abnormal-voltage alert

These systems provide an additional level of protection during normal charging, although correct battery charging and handling procedures should always be followed.

AC & DC Power Options

For everyday use, simply connect the D300 Plus directly to 100–240V AC mains power using its built-in power supply.

For racers or users requiring maximum charging performance, the charger also accepts a 7–30V DC input. With sufficient DC input power available, each channel can deliver up to 350W for a combined maximum of 700W.

This gives you the convenience of a self-contained charger at home while retaining the ability to access significantly more power from a suitable external DC source.

Compact & Powerful

Despite its impressive output, the D300 Plus measures only approximately 145 x 76 x 62mm and weighs around 530g.

Its compact size makes it easy to carry in a pit bag or toolbox, making it equally suitable for permanent use on the workbench or taking to the racetrack.

With two independent channels, high charging power, G-Tech automatic battery recognition, Bluetooth app connectivity and broad battery compatibility, the Gens Ace iMars D300 Plus Black is an excellent all-round charger for serious R/C enthusiasts.

Please Note:

This is the GEA300WPLUS-UB Black version of the iMars D300 Plus. The GEA300WPLUS-UW is the corresponding White version. Gens Ace lists both colour options within the D300 Plus range.

The advertised 700W maximum charging output requires a suitable external DC power source. When powered directly from AC mains, the charger provides up to 300W total charging power.

Always select the correct battery chemistry, cell count and charging current when charging conventional non-G-Tech batteries.
