I just purchased this Heltec v4 WiFi LoRa 32 Expansion Kit from amazon. https://www.amazon.com/dp/B0GQSDC2WM?ref=ppx_yo2ov_dt_b_fed_asin_title

It does not include the battery. The amazon page seems to imply that a lithium ion 18650 battery is required. I purchased one locally (18650 Ultralast button top) and it does not fit. The PCB is too small by a few mm to fit this battery. It cannot be "forced" into place. I am at a little bit of a loss to know what battery I need.

Does anyone have any experience with this device and spec'ing a battery for it?
