So with time on my hands I have gotten bored. Today I decided to build a few things that I had been wanting to do. The first pics are the "Go Battery" in a .50 cal can, the next are the "light in a box". The battery box uses a 33ah SLA battery and has a voltmeter, dual USB charging, and 2 marine lighter sockets. The light box uses a 17ah SLA and a single 17 watt /1980 lumen 600K flood light. It easily lights a room or work area and I know will run for 8 hours (tested).
Nice setup...I do wonder what the relay is for. I don't see anything that draws enough current to warrant it...except the TS-2000
I built something like that using LiFePO4 batteries. My big one has a 2000w samlex pure sine power inverter that can power my mig welder at full power and my tig welder at partial power.
Techsar:The relay will power the binding posts I'm going to add....when I find them. BT:Straight TS-2000. Talked to you that one time with it.
You might consider instead of binding posts one or two of the various sized Anderson Power-pole connectors. The small size is pretty much the standard in the ham community for portable power. I'm not a huge fan of APPs but they arent bad and i have used the bigger 80 and 250 amp sizes a lot with good results. There is a big 450-500 amp version common on forklifts that i have used on jumper cables. I permanently mounted a connector on front of my snow plow truck wired to the batteries and put a mate on my jumper cables, could hook up without raising my hood super quick: worked great. AT
I did similarly on my Jeep. Could swap the winches for jumper cables, on front or rear of the Jeep. Powered by 2 - Optima Yellow Tops, back then.
I bought a crimping tool for the small size (good to something like 30-40 amps) and can install an APP in just a couple minutes. Then all future connections and disconnections take seconds, are simple for others to perform and reverse polarity risk mostly goes away.
