How long does a Badger 2040 W + LoRa last on battery?
At about 20 mA average draw, a Badger 2040 W + LoRa runs roughly 6.3 days on a 3000 mAh 18650 cell and 20.8 days on a 10000 mAh pack. Real-world life depends on transmit duty cycle, screen and Bluetooth use.
What is the range of a Badger 2040 W + LoRa?
With the stock 2.15 dBi antenna at 5 m, the theoretical line-of-sight range is about 14.3 km. In practice terrain and obstacles reduce it; raising the antenna is the single most effective improvement.
Is the Badger 2040 W + LoRa good for a solar node?
Yes. Its low average draw (20 mA) makes it well suited to always-on, solar-powered relay nodes.
