I need more lipo and wanted to try something lighter weight to see how the HCP100S will do. The Hobby King Nano-Tech 330mAh made for the Trex 150 touts 45-90c. Let’s see how it matches up to the HiSky HCP100S stock 450mAh 25c pack.
I have two of the HiSky 450mAh and three of the Nano-Tech 330mAh.

I was only able to pull 2A from my iCharger 106B+. And I estimated that the HCP100S pulls about 2.8A or so. But the graph above gives us a good basis for comparision.
The NanoTech claims 40-90C. And it does gives an ok discharge the first minute or so. The HiSky 25c does keep the voltage up longer.
I get about 6mins with the 330mAh pack. And about roughly 8mins with the HiSky 450mAh.
The HiSky’s ability to maintain a higher voltage through the flight makes up for the fact that it’s a heavier pack. My skill level doesn’t allow me to feel the weight on the HCP100S. The brushless motor sill makes it super power and peppy to me. And the weight makes it feel more stable in the breeze.
But the Nano-Tech are about half the cost, factoring HobbyKing shipping. And 5-6mins is a good amount of time for flying. You just need to install a balance plug to use the Trex 150 compatible lipo.
Just thought I’d share.
update 2015-07-01: I currently like the Nano-tech 300mah 2S 45~90C. The measured IR is about 20ohm versus the 50-60ohms of the Trex 330 version. And it seems the Trex 330 version is already slightly puffy even though I haven’t flown it much.
