Should be able to power my ic-7000 for almost 2 hours of continuous tx at 100w. Now to install it in my POTA pack.
I looked at the spec sheet and it seems that just taping the cells together like that should provide necessary support for all but the outer sides.
A clamp wouldn’t hurt, but probably give me negligible benefits in the projected lifetime of this pack. I’m not using this very often so the pack will age out before charge wear will be an issue. Say I get 300 charge cycles over 10 years, that would be heavy use for my radio pack.
I would look at fabbing up a box that fits snugly, rather than “clamping” them. That could protect against puncture as well. A 3d print or thin plywood glued together would be fine.
