Raising a battery terminal

I did ask Litime specifically about this and they said it could lay on any side except the top or the front (the side that is facing up in the picture), but thanks for checking. :)

FYI, the reason I can't come up vertically from the terminals is because I'll be placing my inverter on a bracket right above the battery.
Not sure this will be helpful but I have the same battery and am doing a DIY build using a Ridgid Gen 2 XL rolling toolbox. I chose that particular box because the 12v 230ah LiTime LTCP battery fits vertically in it nice and snug because of the side support rails, but the primary consideration was that the wheels are removable (by undoing a latch) and don't have a protrusion inside the rear base and back wall of the toolbox. I plan to mount BougeRV 2000w PSW inverter along the rear wall instead of on top of the battery with a 12v fan on either side for ventilation. The attached pic shows the general layout of the 2 major components. I'll have a shelf above the battery and inverter for things like the shunt, fuse blocks, and bus bars.

Being a novice, this project is a lot more involved than I originally envisioned. FWIW, I found this thread while searching for info on 90-degree lugs and twisted busbars which I think will help simplify wiring the battery and inverter. My plan also includes an upper identical toolbox that will hold at least 3 chargers (Victron 100|50, Redodo 40a DC-DC plus MPPT, and a Redodo 40a AC-DC charger) multiple 12v and USB sockets, fuses and blocks, pv interrupt switches, etc., and provide storage for pv and shore power cords. I'm connecting the two boxes using Anderson SB175 plugs and have smaller SB50 plugs (including a Smurf blue pair for the Victron) between the pv and chargers. Basically I'll have one box for energy storage and to power appliances, and a second auxiliary box for charging. I also plan to make a tabletop for the upper box lid for use when the toolboxes are stacked and used together.

Does anyone know if it is acceptable to take straight cable lugs and bend them to 90 degrees (or whatever angel fits best), or does that stress the connector too much? I would think that copper should be soft enough to handle this kind of forming, as long as it's done gradually with a vise and an appropriately-sized rod in the barrel part to maintain shape. I know there are right-angle lugs available for purchase, but are those pre-formed that way or just bent carefully from straight ones anyway? I'm probably going to need to use some for my bus bars.
Searching today for angled lugs and twisted busbars I discovered this YouTube video. Sounds like it is an acceptable practice to use the method you describe and the end result may be better than stressing the cable with sharp bends. (Not sure about that since I'm not an electrician, but it makes sense to me.)
