One problem you may run into here is that 3.7V is a *nominal* voltage; these batteries are usually charged up to 4.something volts. Tangara considers 4.2V to be "full" and 3.5V to be "critical". You'd have an easier time starting with another shape of lithium battery that also outputs around 3.7 nominal volts, maybe an 18650 or similar?
An alternative route you could take, depending on *why* you're doing this (do you just want the battery to be easily swappable?), is to make an alternative back half for the case that's easier to remove so you can just unplug the battery and plug in a different one.
