I recently bought the Charger 2, with the DC hub for charger 2. I have a Portable power station plugged in via PV port and the charger 2 connected to my Ford transit battery. To use the DC Hub for charger 2 after the car stops, you must have a “parking battery” or power bank battery plugged in via P090A port. I have a B230 which I have plugged in via that port and have that turned on. After the car stops and I have already turned on the DC hub, it will stay on only via the power of the b230 power bank. The FAQ says the PV port is too weak to power the DC hub after the car stops.
In my case though, the DC hub sayed on after the car stopped only for about 2 minutes, and then the charger 2 went into sleep mode, even though the DC hub had 10watts pulling from a fan. There is no settings in the bluetti app to prevent sleep mode. I called bluetti support to see how I prevent sleep mode and they said I need to be pulling 5-10watts or more to prevent sleep mode of the charger 2 to the DC hub.
Also, if you are reverse charging your car, you cannot use the DC hub at the same time. Which makes sense but you need to plan this into your electric build workflow, especially since the Anderson connector for dc hub for charger 2 will have power turned off at random times until they build out the app more (I hope)
I’m writing this because if you were planning on using the DC hub full time plugged into the charger 2/ power bank, it will have weird quicks and shut off randomly. They are not publishing my review of the DC hub for charger 2 yet, which seems odd. They definitely need to fix some bugs and add more customization of features for the charger 2 / DC hub. I am also seeing a random error (G053) which has no actionable steps or documentation.
I’m am the guinea pig for the charger 2 / DC hub apparently. Bluetti please add more support for these products in the app. Way too may things undocumented. Please reach out to me, I would be happy to help with app testing or idea development.
