Ok so I think this ProTek life battery is ok, I charge it on my Hyperion it shuts off at 7.2v and then I put it in the radio and it drops to 6.8v very fast in like 3min, and that's why I thought it was bad but then it held from 6.8 to 6.7v for a little over 3hrs then I shut it off. I should be able to run it down to almost 6v so that is plenty of time a shit ton more than the factory one. U guys that have the same ProTek battery 2 cell 6.6v 2100mAh does yours do that where it drops from 7.2v to 6.9 6.8v quickly?
