Hallo ,
Is it possible to extend the AC180P with battery B210P ?
No - The AC180 series of power stations operate at a different voltage to all expansion batteries, with the exception of the B80. That said, the AC180 does not have an expansion port to direct connect to the B80 and would be used in “Power Bank Mode” and would require an interface cable to do so, using the AC180 solar input port.
Also, as the B80 is paired with the AC60 for expansion capability, you would not be able to charge the B80 via AC input unless you have an AC60.
As an aside, I have a spare 100Ah LFP deep cycle battery, that I can connect to my AC180. I am soon expecting delivery of the Charger 1 which I can connect to that LFP battery. This will allow me to rapid charge all of my power stations at up to 560W or their max input as per specifications. The cost of the Charger 1 is far less than an expansion battery and the spare LFP will give me near 1,300Wh of extra capacity.
I have 3 x AC180s and 2 x AC70s + an AC200P. They have varying input voltages to the solar input, where the Charger 1 is connected and the Charger 1 has a variable output voltage of 15 to 56V. to suit them all.
I forgot to mention - I also have a vehicle mounted 375W Victron inverter to charge all but the AC200P in silent mode.
Also, a 15A Victron Blue Smart battery charger for the LFP charging that works from mains input or generator. It’s all about more than one option.
Notwithstanding solar charging options.
To add to my previous posts.
I don’t intend installing the Charger 1 (C1) into my 4x4, as I have multi use scenarios. As I already have a 40A Anderson plug on the rear of the 4x4 for RV towing and want to use the C1 at home or when camping, I’m making up another cable to suit the C1.
The C1 is supplied with a 5 meter cable which, for, home use is way too much cable length to handle. I’ll make up a shorter 6AWG cable with an Anderson plug on one end and replicate the other end, same as the C1 OEM. I already have a 30cm (12") 6AWG cable with eye terminals to battery and Anderson the other end for the LFP. That means the new cable will fit it or my 4x4. I estimate around 2 meters to get from the rear bumper to where I place power stations in the rear, with spare length.
The 30cm cable has a Midi fuse already inline and the 4x4 is Midi fused under the hood, so no need to have one in the new cable. I will probably operate the C1 at around 35V to lower the charge rate to around 350W, primarily to not overtax the 4x4 alternator and stay within the fuse ratings already installed (40A).

This issue has been discussed multiple times. As you can find on the forum, the AC180 does not support expansion with any battery packs.
