SUPER POWER SUPPLY 15 VOLTS @ 7 AMPS Power so smooth and clean that it's like running on a battery

This is a low-resistance, Micro-size 2-Pin Ultra Plug Connector from Deans. This design eliminates the possiblility of reverse polarity connections. Provides a secure connection for battery and motor connections on R/C vehicles.

This is the WS Deans 3-Pin Connector Set.

Low resistance with gold plated contacts
Compact size and light weight
Polarized so as not to be installed backwards
Great for battery and servo connectors

This is the Micro 4R Plug by Deans for battery to speed control.

Deans Connectors offer less resistance
Lightweight
Allows current to move very fast
Functions as a battery plug: female-battery, male speed control or as a motor plug: male-motor, female speed control

Deans are Faster, Lighter, and Create less resistance which equals MORE POWER! The Ultra Plug™ has held the number one position since its inception as a high-power connector. Includes heat shrink tubing.

High capacity 12V 7AmH gel cell will fit any field need.

Size: 6" x 2.5" x 3.7"
Weight: 6 lbs

Heavy duty power supply now available for Limited Edition, Pro Series "Plus", and Quad channel chargers. 12volts DC at 6 Amps.

Large heat sink for optimum performance

Dual HD AWG22 input/output connectors to double current capacity and redundancy

Output is factory preset to 5.95V, fully adjustable between 5V to 6.5V

When input is higher than 6V or any set voltage, it will regulate to 6V or any set voltage

When input drop below set voltage, regulator is bypassed
