Don't think I have seen anyone posting about this twin pack. Its slim unlike the regular 4.0Ah and retail cheaper too ($89 vs $129).
I have layman understanding about batteries so looks to me both have same specs except one is lighter than another.

Bought one slim twin pack anyway. If anyone can spot the difference (other than weight) please post.
Thanks OP. Looks to be this model:

Wondered if they’d have less power output than the larger format 4.0Ah but both models are listed as 900W.

Might get a second set for the mower.
