Overview
The iMars D300 Plus AC/DC multi-chemistry dual output charger is a compact yet powerful charging solution, designed for users who want to charge two batteries simultaneously without compromise. Built around Gens Ace G-Tech technology, the D300 Plus delivers a smarter, safer, and more streamlined charging experience when used within the G-Tech ecosystem. Now enhanced with Bluetooth app control, it provides fast, reliable performance for serious RC enthusiasts.
Supporting a wide range of battery types, the D300 Plus offers true multi-chemistry flexibility. It can charge and balance charge 1S-6S / 2S-6S lithium batteries (LiPo, Li-Ion, LiFe, and LiHV) as well as 1S-16S NiMH packs. Whether you fly, sail, race, or bash, the D300 Plus ensures your batteries are fully charged and ready to perform. With two independent channels, each capable of up to 16A, the charger delivers up to 300W total power on AC or 350W on DC, depending on the power source.
Beyond standard charging, the iMars D300 Plus offers an extensive range of advanced functions. Discharge mode allows controlled discharging of multiple battery chemistries at rates of up to 3A per channel. The Storage function automatically charges or discharges batteries to their optimal storage voltage, helping maintain battery health during periods of inactivity. Sync Charging mode combines both outputs to provide up to 23A using a parallel charge lead (sold separately), making it ideal for stock racers seeking maximum performance. Digital Power mode transforms the charger into an adjustable power supply for accessories such as soldering irons or tyre warmers, while ExtDischarge enables rapid external discharging via XT60-connected loads.
When a Gens Ace G-Tech battery is connected, the D300 Plus automatically identifies the battery type through the G-Tech smart balance connector. Cell count and manufacturer-recommended charge current are instantly detected and applied, allowing the charger to begin safely and efficiently with no manual setup. The charger also fully supports non G-Tech batteries via the versatile G-Tech balance port. When using standard balance leads, users simply select the battery type and operating mode, after which the charger intelligently detects cell count and applies suitable charging parameters.
The user interface is clean, intuitive, and easy to navigate, allowing confident operation without unnecessary complexity. The bright 2.4-inch LCD screen displays clear, detailed information in all lighting conditions. Four navigation buttons provide quick access to menus and settings, while both charge channels are displayed simultaneously. Individual channel settings can be adjusted easily using the CH/Back button. The user interface now expands to your mobile device (available on both iOS and Android) thanks to integrated Bluetooth connectivity. The app provides real-time monitoring, detailed charge data, historical records, and remote control of charger functions. Firmware updates can also be applied directly through the app, ensuring your charger stays up to date with the latest features.

This intelligent approach eliminates setup errors, improves battery safety, and gives you complete visibility of your battery health and charging history, transforming charging from a passive activity into active battery management.
- Is the D300 Plus suitable for beginners to RC? — Absolutely. The plug-and-play G-Tech automatic recognition feature makes the D300 Plus incredibly beginner-friendly. Simply connect a G-Tech smart battery and the charger identifies everything automatically. Even for non-G-Tech batteries, the intuitive app interface and 8-level protection system make it safer and easier than traditional chargers. The comprehensive protection features also mean beginners won't accidentally damage expensive RC batteries through common mistakes.
- What battery chemistries does this charger support? — The D300 Plus supports LiPo, LiHV (high voltage lithium), LiFe and NiMH batteries. It handles LiPo, LiHV and LiFe batteries from 1–6S configurations and NiMH batteries up to 16S, covering essentially every battery type used in modern RC cars, RC trucks, RC buggies and RC crawlers used throughout the UK.
- Can I charge two batteries at the same time? — Yes. The dual-channel design allows you to run two completely independent charging sessions simultaneously. Each channel operates independently with its own voltage, current and mode settings, so you can charge different battery types, chemistries or cell counts at the same time without interference.
- What input power do I need for this charger? — The D300 Plus accepts AC power from 100–240V (standard UK mains is 240V), making it compatible anywhere in the world. For DC operation, it accepts power from 7–30V with a maximum input current of 34A, allowing use with high-capacity power supplies for faster charging speeds.
- Does this charger work with non-G-Tech batteries? — Yes. The D300 Plus supports both G-Tech smart batteries and conventional RC batteries.
