The white Gens Ace iMars D300 G-Tech is a dual-channel charger intended for RC car, truck and aircraft packs. This entry describes the white D300 model rather than the black version or newer D300 Plus.
Charging power and features
The D300 platform supports up to 300W combined charging from AC and up to 700W from a suitable DC source, with separate channels for two packs. Charging modes include balance, charge and storage, depending on the selected battery chemistry. G-Tech batteries provide automatic parameter recognition; conventional compatible packs can also be charged by configuring the required settings.
Who should buy this charger?
Best for hobbyists who routinely manage two different 2S–6S LiPo packs, or who want a single bench charger for both battery upkeep and charging. The dual outputs use XT60-style connections, with additional leads needed for battery plugs such as EC3, EC5 or Deans unless the offer includes compatible adapters.
Limitations and battery safety
The quoted DC wattage requires an adequately rated external DC power supply; a household AC outlet provides the lower AC power budget. Check the accessories included with the exact white listing, because similar D300 variations and third-party sellers may bundle different adapters. Use a nonflammable charging surface, never leave lithium packs unattended during charging, and stop if a pack is damaged, hot or swollen.
