is it bad practice to leave the bluetti elite 200 v2 power station plugged in all night when it gets to 100% and then unplug it first thing in the morning?
or just unplug it right away when it gets to 100%?
Don’t these things have overcharging protection?
e.g. my vehicle’s dash-cam system, it is plugged into the elite 200 v2’s dc port so while the power station itself is being charged via it’s power cord via the grid, then is also my dash-cam system being powered by the grid itself too?
since, i believe that these things have what is called pass through charging.
TLDR - Passthrough charging means you can use the unit for both charging AND discharging at the same time. UPS mode is basically i’m not using the internal battery to power the AC inverter until grid power is lost.

Passthrough charging simply means that the device can recharge the internal battery while supplying a load at the “same” time. You can charge and discharge at the same time. The biggest concern with passthrough charging is heat. When you are charging the battery at max from the wall, while at the same time maxing out your output (say you are running a power tool) both generate heat which prematurely kills the battery and reduces its life cycles, if you abuse it repeatedly. Essentially you want to avoid both charging AND discharging at the max rates.

Whenever the unit says GRID its functioning as a UPS meaning you have the unit plugged into the wall at your home for example. How UPS mode differs from passthrough charging is that primarily the difference is the battery is not being discharged and charged at the same time (if you are just using AC side only). Power routes through to the AC inverter and power is supplied that way. However the battery is still connected in parallel and its how it can detect when a blackout/brownout occurs, switching to the internal battery. The UPS side will only pass power to the internal AC inverter ONLY, meaning if you plug something into DC side directly on the unit it will discharge the actual battery. You just won’t notice any changes because the unit is also being topped off at the same time so it stays relatively around 100% as long you have grid power. The AC inverter is getting its power from the grid NOT the internal battery. The BMS will still function as normal in this case monitoring the state of charge and what not because its connected in parallel. When you plug the AC cord into the unit there is a pathway to both charge the internal battery and power the AC inverter at the same time, it’s just a matter of whether the internal AC inverter is using power from the internal battery itself or the grid.
