Hello,
I wanted to share my new booster/battery setup with you. I was tired of being tied to the machine by using the stock harness, and I wanted an inexpensive source of backup batteries. This setup allows me to use batteries designed for RC cars. These batteries are available at hobby shops everywhere and come in some large capacities. I've been using 5000mAH batteries, but recently bought an 8200mAH one. I estimate the total run time of 8-9 hours. The other good thing about RC car batteries is the availablity of some nice and FAST chargers. I am using one from my RC car racing days that works great.
I also wanted to boost the headphone volume, and allow speaker use if desired. I have tested the unit with several pairs of headphones, and I have also driven 4 and 8 ohm speakers with it. The sound is crisp, clear, and plenty loud. The amp is capable of almost 2 watts into a 4 ohm load. I am giving the audio a 6dB boost within the amp, and I'm controlling the volume from the GPX control box. I didn't feel a need for a volume knob.
Hope you like,
Best Regards,
Brian
