Lipoly Single cell voltage booster for Receivers
This little unit plugs into your single cell lipoly and will boost the voltage to 5V, allowing you to run a receiver on a single cell lipo!
Why would you want to do this? Less weight of course!

According to the HC/HK info above, the input voltage range is 2.7-4.2VDC. According to the sticker on the Voltage Booster, the input range is 3.2-4.2VDC. According to the manufacturer * hxxp://****mpnset****/english/product.asp?ArticleID=708 and the printed manual that came with the Voltage Booster, the input range is 3.7-4.2VDC. Well which is it? I was hoping it was 2.7-4.2V or 3.2-4.2V. So I did some testing. With a 4 ohm resistor on the output and varying the input voltage with a good power supply, the following was recorded: Input V___Output V___Output I___________ __4.2_______4.72_______1.11_____________ __3.7_______4.56_______1.08_____________ __3.4_______4.47_______1.05_____________ __3.2_______4.35_______1.02_____________ __3.0_______4.20_______1.00_____________ __2.8_______3.95_______0.94_____________ __2.6_______3.50_______0.82_____________
The booster finally dropped out at 2.4V. This was very encouraging. While the Booster was still in the dropped out state, I started raising the input voltage to see when it would "drop back in". This did not happen until 3.4VDC with the same load connected. I would like to have seen this "drop in" voltage be a little higher. The Booster became very hot during this test, even started to smell a bit.
Conclusion: If you can, raise the low voltage cutoff of your speed control closer to 3.4V. The Booster should be kept in the air- stream if you are going to operate anywhere near 1amp, it will get hot! All this being said, I have still not used this booster in a model.

I guess 2 to 3 grams judging by the size of it compaired to the 3.5 gram receiver. My question is how long will it last with a 600mAp batt??

Mine has arrived - it weighs 4.4gm. Now need to find an application for it - intention was to keep Rx and servos happy while driving the little 2gm motor from one cell with its micro ESC. Seems a bit heavy for that - might be good to fly a glider on one LiPo cell?
