After thinking about different ways to build my 14S10P triangle battery for my BBSHD hardtail I arrived at the following design:

I have access to a lasercutter at uni and am planning to cut the shape from 4-8mm poplar plywood sheets and glue them together to form one big solid block.
The size of the holes was chosen so the cells fit very snug and don't move, I've only tried it with one 4mm sheet so far though.
I will be using Panasonic NCR18650PF cells.
The cells will be spot welded with 8mm x 0.2mm pure nickel strip.
The distance between the cells is 1mm in the design and is around 0.76mm when lasercut (laser kerf).
The battery pack will then go into this triangle bag: https://www.aliexpress.com/item/48V-36V-E-BIKE-Electric-Bicycle-Triangle-Battery-Bag-Black-Bicycle-Frame-Triangle-Bags/32830559950.html
What do you guys think about this idea?
The wood is very lightweight but should be very strong glued together and with all the cells inside.
Can you think of a better suited material for this? A different kind of wood?
Thermals should not be a problem since I'll be running the pack at 30A max.
The bike will be used for commuting, climbing hills and long distance trips.
