I connected a second #battery to my #solar node (one in the #RAK, one in the #MPPT board). I thought the second RAK would drain first, but that's completely backwards!
From the RAK's perspective, it's always going to draw from the solar side, so it'll never use its own battery until the other one ia dead and it's dark out.
The other interesting fact is the RAK battery went from almost no charge to 70% in a single day. Why? It's draining the other battery.
Why? Again, as far as it is concerned, that isn't a second battery, it's a solar panel. All this means that of I ever see #meshtastic report a low battery, I know we are in real dangerous territory. That'd mean it drained one battery completely, which is not trending in the right direction!
Experiments are fun 🤓
