QRP RANGER
An innovative portable energy system, optimized for mobile radio in the field.
How do you define ‘state-of-the-art’ in mobile radio power?
Start with 100 watt hours of the best battery chemistry available to civilians. Wrap it in a multi-layer armored shell that shrugs off bumps, drops, vibration, moisture, and the realities of field use.
Add internal protection for over charge, over discharge, and short-circuits.
Incorporate a built-in, fully automatic, three stage, 3 amp solar controller… making the system capable of handling direct connection to any 12 volt solar panel from 5 watts to 30 watts, any direct DC source from 15 volts to 20 volts, and any AC power supply that can provide the same.
Include a battery protection module that defends the battery from abuse, and balances the individual LiFePo4 cells each time they are charged, regardless of power source.
Include an accurate volt meter and a low-draw precision amp meter, so the user can see the real-time power demand when operating.
Specifications:
The Ranger is 7″ x 5″ x 2.5″ and weighs 2 lbs, 5 ounces.
-
The battery bank is a four cell, 12.8 volt, 100 watt hour LiFePO4 bank of polymer cells. The best we can find.
-
Internal protection against over charge, over discharge, and short-circuit. Allow to cool and reset if triggered.
-
The charge controller is robust and capable of accepting DC power from .5 to 3 amps, and 15 volts to 20 volts.
-
The Ranger is composed of multiple layers of 3D printed ABS and shock-absorbing PVC rubber. It is not waterproof, but it is capable of tolerating more abuse than you expect from a portable power supply.
-
The Volt meter draws less than 0.006 amps, and helps you confirm incoming power and state-of-charge.
-
The Amp Meter draws less than 0.005 amps, has an accuracy of +/- 0.1%, and samples every 200 mS.
-
Amp and volt meters are recessed, angled upwards, and sit in a ‘light well’ with an eyebrow to reduce glare in sunlight.
-
The diamond grip bungee cord is retained with four bi-directional hooks that allow the radio to be mounted top or bottom, without tools, in just a few moments.
-
A custom Power cable is included. The default is the Yaesu 817 connector. If you prefer something else, send an email or include a note with your purchase, and we will make the appropriate cable.
The Ranger ships with a power cable to connect to your radio and a worldwide AC wall charger.
