RV lithium lead acid battery
240KW/400KW industrial rooftop - commercial rooftop - home rooftop, solar power generation system.
As the temperatures got lower, the differences between lead acid and lithium became more and more pronounced, with lithium losing very little in delivered power. The lead acid battery delivered only 32 amp hours at the lowest temperatures tested. When drawing a larger amount of power (80amps) the results were even more dramatic.
