Please visit his website to learn in-depth how the circuitry works. So what the condition says; if the battery voltage is bigger than the set absorption Voltage, then the battery is considered full. Hi, The discussion here was very useful as I got new laptpo which has Lithium Ion Battery. Upon inspection of the batteries we found formation of white powder at the bottom of the plastic casing. For the IRF4905, this is 20V. Thanks for your help, it was really helpful for me to have my new Laptop Battery understand and how to maintain. Using big electrolyte capacitors can partially dampen the AC factor, but not much can be done to the main DC power-rail voltage drop caused by the battery. As for the ADC conversions values; Ill take it that you are talking about the current? Condition 1) ampVoltage is the Voltage from the current-sensor, battFullCurrentAnalog is the converted number of thebattFullCurrent. Featured Artists; Featured Collections . Wow thanks for the answer, that clears it up ! He has brought a ton of talent, time and dedication to make this happen.
