Battery 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.
Battery testers, such as those in Figure (PageIndex{6}), use small load resistors to intentionally draw current to determine whether the terminal voltage drops below an acceptable level. They really test the internal resistance of the battery. If internal resistance is high, the battery is weak, as evidenced by its low terminal voltage.
e.g. the 200Ah Victron with internal BMS you have 70A charge/discharge current(100A 10sec peak) and with external BMS 200A recommended discharge(400A max) and 100A recommended charge(400A max) current. If you only want to use small loads you should be fine with an internal BMS but if you need large loads you should use …
