May I follow up on this: is there any easy way to increase the deep discharge protection voltage? I use the Lipo Rider Pro as an USB for my Raspberry Pi, but it discharges so much, that it cannot boot up again once I reconnect power (I guess because the RPi draws too much current). I would like to increase the deep discharge threshold, sacrificing a bit of battery time, but enabling smooth re-start
I think, I’ve got the similar problem like mail23: I have a small router connected, and it keeps the battery empty once discharged, if it’s powered on all the time. One way could be a larger solar panel, as for router power + battery charging power.
But a better way would be: first charge the battery to a minimum level (e.g. 10%, 20%) and then switch on load, not before.
The raspberrry pi might also need a lot of power on boot up, like my router, and less at normal operation. So there should be a reserve in the battery before powering up the device…
I don’t know, if all versions have the same charging ic, V1.1 has: seeedstudio.com/wiki/images/ … CN3065.pdf
maybe changing ISET (charging current) might help, but I’ll look for another way…
