How long does a CubeCell HTCC-AB01 last on battery?
At about 5 mA average draw, a CubeCell HTCC-AB01 runs roughly 25 days on a 3000 mAh 18650 cell and 83.3 days on a 10000 mAh pack. Real-world life depends on transmit duty cycle, screen and Bluetooth use.
What is the range of a CubeCell HTCC-AB01?
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 CubeCell HTCC-AB01 good for a solar node?
Yes. Its low average draw (5 mA) makes it well suited to always-on, solar-powered relay nodes.
