Looking at the MTR4B kit with a view to hold a lipo battery within the case.
The site states the case has room to hold a battery.
The batteries I’m looking at are 15 to 20mm high.
The case is 34mm high so available space to hold a battery is 34mm – PCB height.
How much height is there in the MTR4B case from the PCB to the bottom of the case ?
