I have made some tests with a HX160S3 26800mAh power bank and a 134N3P charging/discharging/protection/DC/DCconverter module and I have made kind of the same observation: when they are in discharging mode (supplying power to a load), they stop working after a while for a load drawing small current (I saw that the limit is about 100 mA). So, it seems they must have a minimum load current to work properly.
For the power bank, after like 10 min, it stops working and I need to unplug and replug. For the module, every 10 seconds, it stop working for 30 ms then restarts working until the next cut off.
Does someone know why?
(Additional question: does someone know how to reduce this limit of load current?)
Thank you in advance,
