One thing that I have found with Lithium batteries is that they don't like being cold. It may not be cold where you are but on higher current usage ( my brushcutter) the batteries take quite a while to warm up when the ambient temperature is under 5 degrees.
I use the brushcutter and it runs for a short time then stops, it does this for about 5 minutes or more depending on how cold the air is. Then once the batteries are warm it keeps running well.
That may not be a problem where you live, or for so low a current draw, but in Tassie Lithium batteries take a while to wake up.
