Solar powered esp32 project sanity check
Can you tell me whether this looks ok?
In particular I wonder whether it's ok to put the MPPT and USB charger just in parallel like that. I want to use the the USB charger just occasionally in case the battery depletes. Do I need some blocking diodes? Since they are both chargers I'd kinda expect them to be already protected against depleting the battery so against reverse current - is that sound?
The battery is a 12000mAh pouch battery with some unknown protection board at the terminals (seems these pouch lipo batteries from AE come with such a board most of the time).
The MPPT charger has continuity between solar gnd and battery gnd.
The MCP1700 LDO recommendation I took from this: https://randomnerdtutorials.com/power-esp32-esp8266-solar-panels-battery-level-monitoring/
How likely is my battery going to explode?
