Don’t you really want to know what total height you have to work with first and then start to subtract from there to know what your starting point is. ??
Example:
my height is 50mm from the bottom of the chassis to the top of the lid.
my battery tray is 5mm
my battery strap is 6.2 mm
my battery wires under the strap is 4mm
I'm now left with a total free height of approx 44mm that I can allocate towards battery / lipo height. What is your total free height? and how tall are the 123 cells stacked up on each other?. I've found that on average a 5000mAH lipo works without shimming the lid. as for a 3s, 4s, 5s, etc, what can your ESC handle?.
Either way it's more money you'll be spending..
Nice build by the way..
