RE: E Flite Eratix 3D 25e ARF Owners Club
The Power 32 motor runs around 800 watts, so you have to have a battery that handles that much power. So, if the maximum power that the battery can deliver is 500 watts, then your Power 32 will not run at its maximum. Hopes this makes sense.
Whenever I want to do lots of hovering, I use a small, 3 cell, 1800mah battery with a 40-50C rating. It delivers all the power I need to hover and do harriers over the field. The battery lasts about 8 minutes. The rest of the time, I use a 4 cell, 2500 mah with a 30C rating which gives plenty of power to do anything I want.
The batteries you mention are quite heavy compared to the small batteries I'm using.
I've been flying the Eratix ever since they came out several years ago. I'm on my third one (the other two are in airplane heaven).
Hope this helps you out.
