EcoTrek state of charge

[Rob S]

I have a 2021 zion with 400 amp lithium batteries.

It also has the electric cooktop, which seems to drop the battery voltage quite quickly when in use. It come back up partway when the stove is turned off.

Does anyone have a good rule for what battery voltage should read at different state of charge.

I do not have the firefly system, so it just has two voltages showing. Fully charged shows around 13.2v, and after running say the fridge overnight it goes down to around 13.1

A battery chart I got says once you reach 12.9, it is pretty much used up. Is that correct??

Any info or experiences you might have would help here.
