Warning for #meshtastic users buying batteries: the connectors aren't standardized. The 5000mAh batteries I bought have a larger connector than will fit on the #Heltec #v3 or the #LilyGo #Tdeck. You have been warned.

If you're new and don't want to be like me, get a pre-made unit from someone who already learned this lesson (and either buys matching gear, or solders on the needed power connector for you).
