Connector A or B for ECS2900

[Rkjpayne]

I have an ECS2900 v2. I want to add some more slaves but there is apparently connection type A or B. How do I find out which one I need? Many thanks

There should be a big label on the side of the battery, the letter in the left hand corner is the connector type.

Thank you V much. It was on the back (I’d looked on both sides but not the back as it was hard to shift) - a great big red sticker!
