I have my dash-cam system plugged into my bluetti elite 200 v2 power station 24/7. With the screen on it draws 6 watts, and with the screen off and still recording it doesn’t even register 1 watt.
Tonight 04-23-2025, I checked it in the evening at approximately 34%, then at 22:30 I checked it again and it was at 10%.
What’s the deal? Is it not properly calibrated? It does seem to go low fast once it gets to as low as about 40% or even 30% as demonstrated tonight. Then it seems the percentage drops like a stone. Does anyone else have this problem? Let me know if I can provide more details.
Hi @sacrilegious, The Elite 200 V2 does have self-consumption, and it becomes more noticeable in environments with abnormal temperatures.
When DC output is enabled, the self-consumption is 6W per hour, and when AC output is enabled, the self-consumption is 15W per hour.
We assume your dash cam system is a DC load, is that correct? If so, we recommend turning off the AC output, which can save some power.
Is the ambient temperature at night suitable?
Could you please provide the SN code and current firmware version of the Elite 200 V2? We will check if it has been upgraded to the latest version.
Your suggestion is correct, recalibration is very helpful.
Please follow the steps below to recalibrate it:
- Please discharge all the power (charge AC & DC appliances with the power station) until the SOC is 0%, turn off the machine, and leave it for 3 hours till it cools down.
- Please charge it again, please do not load any device when charging it, and do not interrupt it while charging.

Please let us know if it does help.
If not, please contact us for further service.
Self consumption is essentially how much power the unit uses by itself when you leave the DC or AC buttons powered on (lit green) with no load connected. Generally the unit will also have a “sleep” timer as well by default meaning if you left the AC button on and no load was detected it might shut the AC side off after say 4 hours of inactivity. Even at 15Wh of wasted electricity per hour it would only deplete the battery 0.7% per hour. So in 6 hours that’s only 4%. Yours went down 24% which would be the equivalent of 36 hours.
The battery management system (BMS) has an algorithm which it uses to calculate the current depth of discharge over time to display what it “thinks” the battery is at. Because the lithium iron phosphate battery in the Bluetti Elite 200 V2 has a relatively flat voltage curve the difference between say 30% to 70% is very small. Power stations can all of a sudden drop from 50% SOC to 30% suddenly due to user behavior or external factors causing the BMS to eventually drift and make an inaccurate calculation. A common reason would be when someone only uses the power station in a narrow range, say from 40% to 80%. Because there is very little voltage difference at this range, the SOC can become out of whack. Likewise if you leave the unit partially discharged for a long period of time. When you do a recalibration by charging it to 100%, then discharging it at a constant steady load, then recharging it to 100% again, it gives the BMS reference points to realign the SOC, so the percentage you see on the screen is now accurate. In other words to avoid potential miscalibration headaches you actually “WANT” to perform full discharge and recharge cycles occasionally to avoid staying in a narrow band all the time (30-70%) which can cause the BMS to drift over time.

i private messaged you the info. also, yes the dash cam system plugs into a 12 volt dc power standard car charging port, just like the bluettie has! actually, if the bluetti elite 200 v2 had at least one extra 12 volt port it would be perfect!
my a/c button has no reason to be on. there is no reason for it to be on while i am not using it.
okay, i will discharge the unit completely and then unplug the dashcam system and then plug in JUST the power charging cable to the unit. I also went into the app today and updated everything having to do with the power station software wise.
