<p>Migrated reply #5121</p> <p><b>New page</b></p><div>Hi!<br /> <br /> I experienced also some strange behavior. Shorting Chg En charges the batteries very fast to 100%, and then it goes down to 93% in couple of hours and then it will be recharged again and repeats. Very fast cycle, I think it kills the batteries very fast. If I don&#039;t short, the batteries go down from 100% to 95% in a night time, so it is also very fast. I assumed that if the board is powered, the batteries remain intact and keep capacity for months or so.<br /> <br /> What I found out is that the GPIO16 is not exported by default, so I think the board doesn&#039;t find the value of the non-existing file, not 0 nor 1, and this let the board drain the batteries somehow. If I export it as a oneshot service at boot, and put the value 0 as it is above as a sample shell .sh file (charing disabled), then I have the 100% now more than one an a half day stable. I expect it to stay so.<br /> <br /> Can anybody confirm that it is the correct usage for the v2.5? I mean that the hardware jumper cannot work correctly without exporting and setting the pin 16 by software at boot?<br /> <br /> Thank for an answer in advance!&lt;!-- migrated from Comments; original IP: 185.50.233.235 --&gt;</div>
