I have my charge controller separate from the power box because I have 3 boxes and buying charge controllers for 3 boxes is expensive. I have Anderson connectors (outlets) that allow back feeding with a charge controller. The AC battery charger is also separate from the boxes but connects to the Anderson outlets. This allows the battery to be bigger in the box. I think of all the things that connect to the power box to be accessories and have a cardboard box for the stuff. One box does have a stereo in it with side speakers that can disconnect and sit separate from the box. Two of the power boxes are "ghost boxes" in translucent white.
Hey Don, I'm in the process of collecting parts for my first dyi, so im pretty new at this. Just curious...if I put a 110 inlet in to charge my battery with home current like you did... How would I need to wire it if I had a charger in the box? Sorry if that's a dumb question, I just cant figure that out! 🤔 Oh, and where did to get that inlet with a switch? Thanks After I posted this I found the exact switch you have on Amazon. It already has the positive, negative, and ground wires with spade ends... I just don't know where to put them. I'm guessing the single red to the fuse box and the other 2 to the charger plug? Sorry again.
Hi, The 110VAc goes to power the charger. The hot wire goes through the fuse and the nuetral wire connects directly. The output of the charger connects to the BMS output. Do not connect it directly to the battery. The batteries will charge through the BMS which will cut off the charge when the batteries are full. The BMS output is the output going to all the 12vdc devices and switches. Also, for a charger, I used a 15vdc power supply adjusted down to 14.4V dc. You don't want more than that to charge LiFePo4 batteries. I hope this helps. Good luck. I have been using my portable pack alot lately on trips. Recently used with 12vdc air compressor to repair my trailer tire on the side of road. Also rums my HAM radios off grid.
Hi.. at the time, I had about $250 into it with the majority of cost being the LiFePo4 battery cells then the BMS. However, everything has went up in the last few years. Not sure what cost would be today. Add 25%??
WoW! That is a lot of electronics installed into such a little box. Kudos! I love it!
Thanks!
I was considering one of the chynesium power supplies for a battery box
Very nice compact little build. Greetings from Jamaica.
@@lawrencedavidson6195 thank you.

That sounds really nice. Way to go!

Darn, sorry I see you replied a few days ago.
Thank you sooo much!!
Be safe
Hello, so what did it cost to build if you dont mind my asking?

@@donsdoityourself2547 LiFePo4 battery prices have started to go down now.
