I finally have some batteries for my van/portable battery box build, and I could use some help making sure Im not missing anything. Im following wills 400 watt with alternator charging plan. I dont plan on using solar right now though, I was thinking about using a 24v 30amp power supply to simulate solar panels like he does in the youtube videos and use it as a shore charger. Ill be camping in forests for the most part and solar wont do much for me. It will be primarily for my van but will also be used around the house for power outages or working away from the house. Im using the topband navitas 25ah lifepo4 prismatic cells from BH. Do these cells require compression? If so how much? Can I mount them horizontally or only vertical? If Im using one bms I should run the batteries as 8p4s or 4s8p? How does the renogy dcdc mppt know if its pulling to much from the alternator? I believe my van only has an 80 amp alt, and cant seem to find the duty cycle for it. I dont want to burn it out if I can help it. The renogy also has an optional voltage sensor, which battery does it go on I cant seem to find a specific one in the spec sheet. I plan on wiring it so I can "plug it into the van" when Im camping. So using anderson connectors or something similiar to connect the box the 12v fuse block and dcdc charger.
Heres my list of parts so far, I think I have everything covered minus some outlets. I only have the batteries and the 12v fuse block so everything else is flexible.
x32 25ah batteries
1/16 x 3/4" copper for bus bars
12v fuse block
Electrodacus bms
x2 250amp shunt
renogy dcdc mppt 50a
power supply 24v 25a
2000w inverter (for house stuff)
1/0 awg and 4 awg wire
250 amp bus bar
2 cooling fans with temp sensor
65, 75, and 250 amp breakers
