AD584LH Voltage Reference Battery Adapter (V74PX to AG13 Coin Cell)
thingiverse
This battery converter is designed to connect 7 x AG13 batteries (also known as LR44, G13, A76, GP76A, 357 & SR44W) to fit a V74PX battery used on some low-cost voltage reference boards powered by the AD584LH voltage reference. The 15V, V74PX battery is difficult to find and very expensive, so this converter makes using these affordable reference boards easier and more cost-effective. WARNING: The voltage reference board needs a supply greater than ~12V to operate, so stacking seven AG13 batteries together (~21V total) is acceptable. If you're looking to use this adapter for other applications, you'll need to print a spacer that takes the place of two batteries.
