Re: Lifespan of Lithium Ion Solar Batteries

Hi Richard I note your comments on Lifespan of Li batteries is some 3 year old. Cost of batteries have dropped by half and number of cycles have improved as well. Do you have more up to date information and can you shed any more light ( in addition to your artifice) on comparison to Lead batteries. For example since 2017, would you say the superiority of Li batteries over Pb have further increased.
