B500 communication cable (Pack link in/out)

[vuman]

Hello,
I have an EP800 + 2 x B500
I have an extra B500, I would like to expand it to the system but I misplaced the communication cable between two batteries (Pack Link in/out). I do have an extra set of power cables (+/-) came with the EP800.
Where could I buy the Pack Link in/out cable?

Thanks

The cable you’re missing is required for battery-to-battery communication:

• It connects B500 Link-out → Link-in between packs
• Without it, the extra battery won’t be recognized by the system

So yeah—power cables alone won’t work.
