Stupid newb question

[Serum]

Good point; is the eagletree showing these drops?

6.5V on a 3S pack is pretty deep; what is the capacity of these cells? you are mentioning 40-50C, but what current are we looking at?

It's not good for a pack to drop bellow 3-3.2V per cell; it shortens the lifespan, but so does overheating the packs. When the burst are very small, the pack simple hasn't got the time to heat up.

It's obvious that the cells are not up the task.
