Would perhaps adding some protection against over discharging the battery be a good idea? I know Milwaukee tools have this to prevent damaging the battery.
I thought the batteries had that circuitry built into them. If they do, they'll shut down on this the same way they do in a tool. Could be wrong though.
Thanks for sharing, I was a little bit confused at first why you put a buck converter in there because most 12v appliance can operate at 24v also and USB charger will work from anything from 11v to 30 volts and remember that converter has convection losses..if all you need is to us usb charger the run it straight from 18v I will work just fine.
I wanted consistent 12v power so I didn't have to worry about what I was plugging in. For example, my ham radios don't like 18v. I use this to power them when I'm reprogramming. Thanks for watching.
To be honest I clicked thinking somehow you were going to splice off the charging board to add those extra ports. Still that's a cool build. I'm guessing the collection of extra chargers came from acquiring tools that came with them?
I think the only piece of advise I have would be to establish as best you can what you want it to power and build the outlets accordingly. I donhave a video coming up that talks about accessories and how to mix and match with Anderson connectors. You may find something useful in there as well.
It runs my cooler fridge just fine. It only pulls 30 watts on eco mode. I often pull it out of the Jeep and bring it inside when we're getting ready for a trip. I just plug it into this and don't have to go find the 110v adapter.
