I saw the video and that works fine for DJI batteries, but not my Limefuel. Got an e-mail back from Limefuel that informed me that if I put any kind of grease on the contacts (conductive or di-electric) I was going to be very very very sorry I did.
Almost sent it back to Amazon, but decided to plug it in and out of the charger (unplugged of course) to see if it loosened up, and about 50 times around it does seem to have loosened up some. Still takes two of us to drag it free, but its somewhat easier now and has become a bonding experience over the course of this week for my wife and I.
BTW - the trick to the DJI batteries is to dab a little silicone grease on the two slot indentations in the plastic at the rear of the battery. I think I found that on one of Simons youtubes....it really works (but not on Limefuel).
Another note - I'm breaking the Limefuel in right now, but if my math is right, its going to give me about another 3 to 4 minutes of airtime. No issues flying the Limefuel at all (other than getting it out).
thanks for the comments -
