Fair point about the panel putting out slightly less. It's a 36 V Battery pack but due to the cells being optimally charged at 3.6 V I assumed I only needed to charge it at 43 V Give or take This is how I have manually charged and equalized other lithium battery packs in the past off of a power supply
