i bought some yellow wrap a few years ago on ebay and have tons of it left.
i had a buddy with a cell that the wrap got a little beat up and i wrapped it in some tape a little but then remembered that i had the wrap. so i pulled off the tape and it left a bunch of sticky tape stuff so i only wrapped the bottom bit of the battery overtop of the old wrap.
worked like a charm and still fits in his light.
i used that battery wrap on all kinds of stuff. like stuffing RC car electronics in too small of a car. take boards out of the plastic cases that they come in and just heat shrink them and glue the ends shut with hot glue. now they fit in alot smaller place.
I haven't measured it to confirm this but the clear seems a little thicker than the colors. The others from FT are really thin, they're obviously not translucent like the red Sanyo cells, but markings on the cell are still readable through the colored wraps.
I’ve held it over a toaster. Worked well except the wrap didn’t take on enough of the delicious aroma. Easier to shrink it evenly then it is with a butane torch.
I use a hair blow-dryer for the shrink ends and body, and afterwards use a lighter to remove or shrink the crease lines on both sides for a nice tight shrink. The flame from the lighter should touch in a buzz the crease to shrink it.
Is there a similar tutorial on installing cell protection PCB’s. I got these cell protection PCBs and clear heatshrink from Fasttech and I intend to use it on my Samsung ICR18650-28As but I’ve no idea what to place in the positive end yet. :~
