A Bosch battery extender please

[Akiwi]

I tend to go adventure mountain biking with long rides and / or lots of vertical. So I am constantly keeping an eye on my battery to make sure I can make it to the end of my day. Or I carry a charger with me, and make a lunch break where I can load my battery for an hour or so (If I can find a place that allows that).
I have done a few days with over 100km and often over 2000m vertical and up to 3300m vertical.
I love the extra range of the 625wh battery, but it is still often not enough.
I would love a battery extender that could go into the bottle holder and add 150 wh, or so. 200wh would be great.
I don't want to have to carry a complete extra 500 or 625 wh battery. They are too big / heavy / expensive.
I know there are bikes where you can attach a complete extra battery, but a small add on would be great.
Bosch seems to block it so it is not possible.
For other motor brands it seems to be easier.
Please Bosh, make it happen. I don't mind having to pay for a Bosh branded battery extender, but it would be nice to have the option.

I guess there's only so much segmenting you can do, as a manufacturer, before the laws of economic feasibility catches up. First, Bosch had 400 powerpacks... and some wanted a bit more. They came with 500 (same format); but then some others wanted a bit more. Now, they have 625... and a new bunch wants a bit more. Dual battery gives them 1125... and some find that too much or heavy.
You can't expect them to bring out batteries in 100w increments.

Great question and i am with you on all the points you have made.
There should be someone here who can help.

Oooooh, I saw this in a Trek thread.
I wonder if it would fit on my 2020 Cube Stereo?

Though the online reviews look pretty terrible for the company. Anyone have any experience?

Quite a few brands that use the Bosch system now offer range extender batteries, including Scott, Orbea, and Haibike. I wonder if one of those could be an option - most of them seem to have proprietary mounting systems though

Bosch 300 powerpacks are available for £299 but not very practical as the weight difference between the 300 and 500 is minimal.
I’m torn between buying a spare 500 or using the money to save for a full suspension ebike.
I can’t see any 2021 full suspension ebikes which use the Bosch rectangular powerpacks anymore so if I were to buy a spare battery I would not be able to use them in a new FS bike.

Scott and Orbea use them as range extender packs, but you have to spec it on purchase.

I see what you mean. Cool!

haibike has some dual-battery options, as does Simplon.
So, as far as I can tell, there are only 5 brands that offer an external Bosch powerpack option. Very compelling solution though.

But only possible at purchase time, and it uses the Bosch dual battery system. I agree it is good, but not available on Cubes. I like how Haibike has done it, so you can completely remove the 2nd battery holder when you don't need it, and replace it with a bottle holder or something.
Maybe a battery powered pie warmer would be a good option.

I'd rather have a beer cooler...

Some can be retrofitted. orbea, for instance - WILD FS 2020 EXTERNAL BATTERY HARDWARE KIT
