Ok so I have flown another 2-3 times on the pack that is suspect. Today when finished flying the pack felt squishy. Pretty sure it has to go, I don't feel safe using it anymore. It has some knicks on one end where my canopy screw used to be (until I saw it scratching the packs and removed) I can see the foil, and looks like it may have a pinhole in the foil, which may be why that one cell is swelling.

So I wanted to order 2 new packs, so I have 3 to fly with, toss the old one. Techmodelproducts is sold out of the DN power 2 packs, grandrc has either the DN or the Align batteris in 2 packs, for 89.00

Which batteries are the best?

Thanks,
Pete
