Road Angel RA BP 8000

[beatts]

Wondering if anyone has knowledge of this issue I have.

I've bought 2 road angel RABP 8000 battery packs. The website says up tp 3 can be connected to increase capacity. But no instructions or guides on how, or accessories.
I'm not even sure if the main units can be connected together or it's a 'dumb' battery needs buying. ( Road angel say they don't sell any other batteries)

how do I connect these together to increase capacity? There looks to be an x30 connection on the rear that says 'ext batt'.
Road angel technical support were no help when I rang.

Any ideas? Thanks

This is the description page... Literally nothing more than this, no technical documentation, instructions or cables anywhere. Does the xt30 connection play a part, or do you just wire these in parallel. Does the BMS automatically shut off on one unit if 2 are connected. No instructions anywhere.
