A good internal resistance for a battery depends on its type and size. Generally, a lower internal resistance indicates a healthier battery. For example, a good internal resistance for a lead-acid battery is arou.
[pdf] Lithium iron phosphate (LiFePO4) is an inorganic compound that serves as a cathode material in lithium-ion batteries. Its unique olivine structure allows for efficient lithium ion movement during charge and discharge cycles, making it an ideal choice for energy storage applications.
[pdf] A 10A charge controller works with small solar panels pretty well. If that is all you need this device will do fine. But if you intend to upgrade to a larger solar system, consider a larger charge controller..
