(lithium Iron Phosphate) batteries simply set the Ah capacity to the Ah value(s) written on the battery(s) themselves. Add the Ah numbers together if you have multiple AMPS batteries in your install. If you have 3x 12V 100Ah - set the Ah capacity to 300Ah, etc. - Page 7 % SOC meter is always wrong SOC % is best described as a guestimate. It works from simple maths. The user tells the BM2 what Ah the battery is and it knows the current flow in and out via the shunt. It therefore works out a % state of charge.
