Hello, can someone tell me how much you can practically draw from the lead batteries? With the LiFeYPo4 it is 91%, after that the voltage sinks into the danger area. I got a “used” AGM with 70Ah, which shows as idle voltage just 12.3V one day after Volladen and just not 13.0 or 13.3. Sometimes it is also only 12.0V. I loaded it once and then turned on all lamps and unloaded within 3h. When reloading the charger explained 50Ah I would agree with the 50Ah, would be 71%, while 12.0 or 12.3V would look more like a slow death process. How much did the AGM really measure at the time? An old wet battery had just recorded 29Ah at such a death. 2. Does someone have an AGM with them and can sometimes measure the voltage straight? 3. Whether one can take the more robust GEL batteries in the car or tolerate the no high charging currents and burst? Gel should be far more durable than AGM and wet. It is therefore recommended in the yacht area, as they can not allow kittens on the sea.
