Compare the SmartPowerCharge to the DJI HUB

The SPCp3 is a commercial grade QUAD Charging Station designed and built exclusively for the DJI SMART BATTERY (LiPo) that is used in your Phantom p3. This system is MICRO-PROCESSOR controlled with built in Over-Voltage protection, Over-Loading Protection and Temperature Control on power supply input. The Short-Circuit protection on power supply input insures safe operation while charging the batteries. The SCPp3 also monitors the voltage and temperature to each battery insuring that each battery is charged safely eliminating damage and LIPO safety concerns.
The system is capable of charging or deep cycling 4 DJI Smart Batteries simultaneously, your iPhone, or any USB device and 2 rechargeable remote controls (via 2, 26v charging ports on the end of device), all at the same time. You can even DEEP CYCLE selected batteries while charging others. When you put a SLOT in DEEP CYCLE MODE, we LOCK discharge at low voltage down to 8%. After the battery reaches 8%, the system will automatically charge the battery to full capacity. A must have for serious Phantom p3 users.
