I did burned out one blue colour identical xl4015 module when tested current output . I think problem was connecting test lead when module was powered on . Test lead made sparks . xl4015 started overheating . I have 9AH battery , I set current to 2.25A

It heats but automatically shut down when temperature is too high.. I think you connected with wrong polarity or the module was faulty.

No need to remove the module because this module don't do trickle charging, but if you don't remove it, green LED on module always stay on which discharges the battery very slowly..

Hi since you invited questions can you answer this one, you said lead acid shouldnt be fast charge since that can be dangerous, now there are millions of cars around where the alternator gives out at least 70 amps, these dont current limit which means the battery gets the full current minus what the car is using, the question is have you ever heard of a car battery expl*ding from been overcharged?
@Electricquantism402 Жыл бұрын
an alternator charges what is needed by the battery and the electrical load, if the battery is fully charged and the load is light the alternator will charge just enough to keep up with the load, a high output alternator means that it can deliver a high output if needed. High output has nothing to do with the volts, it means it can charge higher amps than a low output when needed. Also its voltage is some little over 12v rather than 14v which damages the battery by overcharging it. Just as a vehicle will not be faster or use more fuel with a full tank than with a tank that is only half full the high output alternator will not deliver more amps when not needed.
@dantronics1682 Жыл бұрын
@@Electricquantism402 Exactly that an alternator give out whats needed by the battery, if the battery needs 50 amps it will deliver that, I notice you mention voltage been little over 12v but if thats the case put a clamp amp meter and the battery and a volt meter, start the car and see what readings you get.
