Overview
Solar Energy Manager is a solar power management module, which can charge the 3.7V 18650 lithium battery through solar panel or USB port.
The module features MPPT (Maximum Power Point Tracking) and protection functions of battery charging and discharging.
MPPT power point tracking can automatically adjust the charging power according to the input voltage, taking advantage of solar energy more efficiently.
The protection circuit of charging and discharging can monitor the battery voltage in real time, preventing the battery from overcharging and over-discharging.
It can protect the battery and prolong the battery life.
Due to its excellent stability and efficient management of charging and discharging, it can be used in solar power generation, low-power IoT and other environmental protection projects.

I didn't like the capacity indicator as it shows a full charge from 50-100% hope it is durable otherwise connected it to a nice big panel will take some power measurements on a sunny day and update review later bms seems to function correctly stopping discharge at around 2.85v and stopping full charge at 4.16v have it connected to a 11ah big brand battery at the moment mppt switch is too small to actuate with hands you will have to use something like a toothpick

I was looking for a quick solution for running an esp8266 with solar/battery. I tried making my own with a tp4056 and buck converter, and since I'm an overall novice in this world, I could never get it just right. The batteries always ended up dropping below shut off voltage and I would have to replace them. I saw this randomly and thought I'd try it. Works wonderfully. I've tried with a 6v panel and a 10v panel via the screw terminals, both charged the 18650 and ran the esp8266 via the usb out without issue. The only negative I could see is that the battery capacity LEDs are constantly on. If there was a status check button that would turn those on for a moment, that would be ideal. Otherwise I'm sure they can be removed if one is really trying to conserve battery. Clearly I'm not as there are definitely more power efficient ways to run an 8266 rather than the USB, but I digress. Bottom line: it just works and does exactly what I need it to do.
