I came across some posts concerning CHINS LFP batteries. If researching the FAQ section I found the following answer from the "Manufacturer"
Q: What is the dimensions of the 200ah batteries? Are they the same as the 300ah.
A: Thank you very much for your question. The size of our 12V 200AH battery is 8.58*9.44*20.55 inch. Our 12V 300AH battery is the same size as the 12V 200AH battery. It's just that their weight is different. Because our 12V 300AH lithium iron phosphate battery uses battery cells with higher energy density, the weight of the battery is different in the case of the same volume.
Is there such a difference in cell density as to allow a 50% increase in capacity in the same volume?
