Go-Kit Power Setup

I use a 7AH 12V gel cell battery, and simply don't worry about discharge protection. I normally just control operating time, and periodicaly check the voltage. As far as charging, I have a little DIY Pwrgate, which is essentially 2 low drop, high power diodes (in one package) and a high power, low value resistor. The resistor goes in parallel with the diode that goes to the battery to limit current for charging the battery while the other leg is plugged in to a standard 13.8v power supply. I modified a cheap 6+2 port POE switch to have 3 ports of 24v, 3 ports of 48v, and 2 unpowered ports available. I keep a GL.MT300N in there to connect to the internet, and two GL.AR150 AREDN nodes in there, with one configured as an access point. Power is delivered from a 12-24V, 12-48V, a 12v-5v supply, all switched with a pushbutton power switch. I'm going to be adding a QC USB3/USB-C charger to the outside that has a built in 11-14.6v meter. With this, I'll also keep an android phone configured for our local mesh's IP phone system, as well as an ip webcam app, to give a few options on how it gets used. All of this fits in a cheap, small plastic ammo can.
