Hi!
Wanted to share some photos of my build of a 5kWh LiFePo4 battery packs that utilizes 16 100aH CALB cells and hopefully answer any questions people might have regarding such a setup. In addition to building the enclosure and installing the pack, I redid a bunch of the electronics. The stuff I currently have is:
* Electrodacus SBMS40 solar charge controller/BMS
* Reliable Inverter 3KW - Some cheap Chinese inverter that so far seems to do the job. I've tested my microwave, kettle, angle grinder, heat gun and AC with it just to see if it's willing to run all these types of loads and it did that without issues. At the peak I was drawing around 100A from the battery to power two heat guns with nothing acting funny for over an hour.
* GL.iNet GL-AR750 Travel AC Router which is connected to a permanently installed Nexus6 phone. This serves three purposes:
1) GPS tracking of the van using google maps location sharing.
2) Provide me with a WiFi access point. It uses a separate carrier than my primary phone so I get better coverage.
3) Provide internet to a Raspberry Pi
* Raspberry pi - currently the only thing this does is pull data out of the Electrodacus to give me remote monitoring/graphing of amount of energy produced/consumed.
* Small reverse camera mounted on the side of the van, since I have no windows and might want to see who's knocking at my door
* A custom wireless LED dimmer controller. I have two transmitters - one by the door and one by my bed, that control a receiver mounted where all the other electronics are and allow separate dimming of two zones in my ceiling LED lights (front and rear)
* A similar wireless controller that is controlled by a fob on my keychain for turning on and off two large LED light bars I have mounted on the roof at the front and rear of the van. I also have wired buttons for those indoor, again using custom hardware/software I designed
* A 500W charger to allow for shore charging, to supplement the 600W solar array mounted on the roof
* I also run all the standard loads (fridge, water pump, diesel heater, etc).
There might be pieces I'm forgetting since this project has many parts in it, but that's a rough overview of what I've done with the electronics. Most of it is probably unnecessary but I enjoy this kind of work, and this is my main hobby.
The full album of some pictures I've taken is at https://imgur.com/a/nkE8J0d but I also attached a few select photos to this post.
Cheers! And thanks again for being such a wonderful and helpful community, my Sprinter adventure would've been a failure if it wasn't for the people here taking the time to answer questions and help others.
