So, what's everyone using for square pack holders with the M-05 v2 anyway? I still haven't decided on a solution.

For one, I have mostly saddle packs which are a bit of a pain with an M-05 as it turns out. Given no proper holder support and also no holes in the middle to plug the power cables there it's a bit of a stretch on my other ESC cable to connect. It reaches, but just barely. Bigger issue is the lack of support. For one battery to test it I put some two-sided tape between the saddle pack cells to hold them together like a stick pack. Since saddles are also slightly thinner than stick packs, I stuck some foam in between the chassis and the battery. It stays in place pretty well, but I don't think I could trust it like that enough to drive (especially in a crash they'd potentially fly).

At the moment I have just one actual stick pack, and it is slightly bulged, making it a tough fit indeed, I'm worried that over time it'd break the chassis even without further bulging, because it certainly puts a stress on the chassis as is. I have a second stick pack ordered, but I still need to be able to use saddles as backup for races and of course for practise.

So, holding the damn things in place. I reckon the saddles will need the foam in any case, and possibly the tape too. But both saddles as well as the sticks still need something to prevent the battery from sliding out sideways (of course with the saddles the cell connector helps with that a bit, but only a bit). Considered Velcro straps either left-to-right or front-to-back direction but that doesn't seem very elegant and given there'd only be tape glue holding the straps in place, I'm not confident they'd stay put in a crash - and front-to-back non-adhesive especially only does so much for sideways sliding. i'd rather avoid anything adhesive in contact with the battery so that they can be removed for charging and of course as not to hamper use in my other cars.

EDIT: Found this 3racing holder... for M05, Graphite Battery Holder ,(M05-20/WO) by 3Racing - I believe the round and square packs are pretty much the same length, so I guess that might work - unless the aluminum shafts would block the connectors? Though I've spent too much on this darn thing as it is And won't be in time for my first one or two races anyway, but for those I guess I can make do with a temporary tape-based solution or something if need be.
