Okay, I did my duty and tried to seRch this out. I have 8 Eve 304a cells. The would be combined into two twelve volt batteries, then seriesed to make a 24v battery. First question. Would this be 4p2s? Next I can get two JBD 200A bms for 125 each., or two 120a for 149 each. This will go into a truck camper that will be getting a 12/24v compressor refrigerator and possibly a 24 volt ac unit as soon as my wife quits giving me the look. Which would be more appropriate?
