Thanks for the responses and vids on re-wrapping batts. I did some research and watched some vids before attempting and had experience with shrink tubing for wiring. The first video here showed the guy lightly pressing down the ends of the battery while "hot" which I'll need to try. My biggest mistake was probably just expecting too much perfection on the ends and "seams" being perfectly smooth.
Thanks again and I'll give it another go.
"O-D",
Sorry you are having difficulties with the skinning. A lot of stuff like Battery Wraps is like putting Wraps on Mods. Some folks will post pictures and it is perfection. I have tried stuff like Mod Wraps and it comes out looking like dog-poo and I will never try it again.
By the way you might want to pick up a junk hair dryer from a garage sale or even a cheapo from Walmart (if it doesn't do the job you can always return it
). The good one your wife has just may have honest temperature control that is defeating you.
Also I am as concerned with looks as you apparently are but sometimes you just have to bite the OCD bullet and remember you are just making the battery safe and it can be very safe even if it doesn't look perfectly smooth and factory done.
By the way the Shrink Tubing sold for wire it generally thicker than the skins for batteries and also come in sever different temperature ranges. You might contact the vendor you got yours from and ask them if they think it should work with a hairdryer. There are just so many YouTube Vids using hair dryers I find it disturbing that you are having problems with yours and feel bad for recommending a hair dryer. I have even used hair dryers for wire shrink wrap and had pretty good success. Of course when out in the field I use a Zipo lighter...
