Hello,
I have a question about my two B80 modules that I have along with the AC60.
I would like to connect the two B80 modules to each other using the aviation cable included with the B80 module, without connecting them to the AC60 module. Is this possible without damaging the power banks?
Thanks
Hi @shirk3n
welcome to the bluetti community!
For the other Battery expansion units, you can connect them together to let them work in paralell mode. I cant say for sure with the B80 to be honest.
It would be more interesting, why you want to do it. The AC60 offer two Ports for Battery expansion, so i assume connecting B80 together and plug ot in AC60 wouldnt work either.
Tell us, what you may wanna do and we can find a solution 
greetings

Hello Erik, thanks for your reply.
Yes, let me explain my situation and why I want to do it this way. I have a small cabinet for a van, and inside it, I need to power a 12V fridge, USB ports, a water pump, etc. I would like to have two independent B80 modules inside the cabinet to supply energy to all these elements while keeping the AC60 outside the cabinet as a portable battery for camping.
As I mentioned, I’d like to connect the B80 modules together and charge them through the car’s cigarette lighter while driving. For additional information, the AC60 doesn’t fit inside the cabinet.
Best regards,
Juan
