All our energy needs, for two of us, living full-time aboard Cushla for the past two years have been met by the lithium battery bank I assembled from individual lithium cells.
I used 16 LiFePo4 cells, each rated 3.2V and 120Ah. Connecting four cells in parallel I created what I call a ‘supercell’ of 3.2V 480Ah, and put four supercells in series to create the 480Ah 12V battery. I have a Daly Battery Monitoring System (BMS) rated for 250A. This protects the battery in a few ways. Firstly, it acts as a 250A trip. Technically lithium batteries will drain and charge
