Questions
- Do LiFePo4 batteries off-gas or can they be sealed?
- Is there existing infrastructure where we can mount stuff
To buy
Modem
Router
Is there a good OpenWRT router with USB? USB 2 is probably fine. Possibilities:
Battery
One of those 12V LiFePO4 modules that look like a lead acid battery and includes BMS? Downside: Monitoring state of charge from voltage is hard but we probably don't need that, just low voltage cut-off.
Battery cut-off circuit
Solar charge controller
- Just one of those MPPT things of ebay/amazon
- Also maybe we could try to make one of the libre.solar devices though the microcontroller can be scarce (mouser has them right now)
Solar panel
We want a flexible panel. Maybe 100 W.
Mounting
Need to sync with folks there.
