Lithium battery potential meter
240KW/400KW industrial rooftop - commercial rooftop - home rooftop, solar power generation system.
Practically batteries will always have some internal resistance. On paper, the value of the resistance will appear low around 0.1Ω for an AA alkaline battery, about 1Ω for a 9-volt alkaline battery, and 20 to 30mΩ for a lithium polymer battery, it could have a significant impact if a high load is attached to the battery.
