the damage to the wrap has mostly been reduced with a "break-in" period, but it's now two batteries that have damaged wraps. i tried to smooth out the wood on the + connection side since as someone pointed out from one of my pictures, there was a piece of wood that was sticking out and a bit scratchy to the finger, and i think that helped, but it's still causing minor damage. i see a new mark every time i take the battery out, even with the batteries going in and out a lot more easily now. so now i have two batteries that are just for the fw7.I'm late to see these posts but wanted to chime in to say that my FW7 also damages the wrap on any cell I use with it and none of the well-intentioned advice from folks here about putting them in differently makes a difference. It's pretty much stopped me from using it since you can't charge it with the battery in like my other portables
Congratulations and well done. The FW7's performance really is first rate. Enjoy man! Oh and keep an eye on the battery wraps just in case
no doubt it's a sweet device, but seems a bit strange that a less damaging battery compartment isn't part of the design, especially when it seems like more than one or two people are having this issue.
