No, once charging has completed the battery enters a low power monitoring state, after a few days it may decide to start charging again for a few minutes. However, I would not recommend leaving the battery charging all summer unattended.
yes, that’s normal if you are charging while connected and using the v5 brain. The brain draws power from the battery, not the charger, so the battery will drop to 85% and then charge will start again.
I wouldn’t recommend leaving batteries on for a long period of time. While the updated battery firmware should make it foolproof, I was a fool with the original software. Now I am attempting to resurrect my pack. Our cell #4 reads zero.
