Learn MoreRising Internal Resistance. High capacity has limited use if the battery is unable to deliver the stored energy effectively. To bring the power out, the battery needs low internal resistance. Measured in milliohms (mW), resistance is the gatekeeper of the battery; the lower the value, the less restriction the pack encounters.
Learn MoreBattery internal resistance is the resistance that exists within a battery due to the flow of current through its electrolyte and other internal components. A battery internal resistance chart can be used to monitor the internal resistance of a battery and identify any potential issues before they become a problem.
