I have a battleborn LFP battery bank that I installed about 18 months ago. I have about 400 cycles on the bank and have been quite pleased with the house bank performance. A friend recently had a Victron LFP battery bank professionally installed and after he showed me the installation I was taken back by the compactness of the batteries. My house bank is 12x battleborn 50Ahr @24v batteries. His bank is 4x Victron 330Ahr @ 12v batteries.
When I compute the energy density I get 15.7 cubic inches per 1Ahr @ 24v for the battleborn while the Victron computes to 7.2 cubic inches per 1Ahr @ 24v for the Victron.
My question is - has LFP energy density really improved that much in the past 18 months or is the Victron LFP batteries using a different form factor (such as pouch form factor which is more energy dense)? As far as I understand the battleborn LFP batteries are using a cylindrical form factor which is the least dense.
