Ah. I see. So... the "power output" is the same but there's just more of it?
Is there any way that the weight of the bigger battery would affect the range of the ride given perhaps the higher usage needed to heft it around (is what I mean)?
Our fantastic hobby was enabled originally by an act of public rebellion.
This week commemorates the first UK National Park established in the Derbyshire Peaks following the Kinder Scout mass trespass of 24 April 1932 that enabled access to the countryside for all, on what was until then, the...
The Evoc has an internal back protector for avoiding this exact problem...
Also... there's a good reason why mountain bikers don't attach bits and pieces like batteries and water bottles to the bike.

I found that I needed the expandable attachable strap to keep them in position. I don't have a very "bridged" nose so they just slip down without it. I have prescription inserts and they are kept in place by being between the outer and inner frames, so you can't take out the rear frame and use...
Hmm. I think maybe you have a point but... there's no water bladder...
Edit: Just seen this. Also Rob's done one of his tech info YT vids about it. Sold. I'm all over Wiggle for one right now.
I've had a look at the Evoc. The advantage of my method is that, apart from the backpack being massively aero-padded, the weight is also supported across the waist from it's position on top of the waist-pack and the shoulder bag is narrow enough to carry the battery in an upright position.
I carry mine (504WH Shimano) in a narrow and heavily padded backpack (Old Camelbak Chaos) that sits on top of a firmly-filled waist pack.
