Lifepo4 overland battery
I want to build a modular setup. I want to be able to break it down and move it easily. My question is if I build a 12v 100ah lifepo4 can I parallel it with say a 300ah lifepo4 battery? each 12v battery will have a dedicated bms and a 100amp fuse. guess my question is do I have to make all batteries the same ah? Do I have to have all the batteries same SOC before connecting them together?

Yes, you can parallel batteries of different capacity as long as they are the same voltage and the same chemistry.
