I may be misinformed but I thought it was bad to draw those down to zero?

Does the batter put off heat?

Almost every lithium battery has built in circuitry to cut off before they get drawn to damaging levels.

Not with the newer chemistry. They are rated for 4-8k cycles depending on the battery. They do get warm when charging but the unit is liquid cooled with a really nice radiator inside so no issues. Maybe if it was installed outside in the desert you might but not here in a VT basement or garage. Some even newer batts are rated at around 40k cycles thats about your lifetime!

I think many manufactures are calling the low cutoff voltage 0% charge now. This lets them more easily communicate that the battery is at to 0% of capacity without the confusion of customers seeing a pack at 300v and wondering why it’s empty.

Edit: spelling
