Im in the search for a Emtb specific Backpack....
A Bosch 750 Battery should fit in it....
The Backpack should have a built-in Sleeve or something to store the Battery rattle free....

@LWstner - good topic. The Bosch Powertube 750 is a big bit of kit at 484mm long, which is where most battery backpacks start to struggle.

The go-to recommendation in this space is the EVOC FR Trail E-Ride 20L. The padded battery compartment has a long Velcro flap that tightens down on whatever length of battery you have, plus a cinch strap that holds it real tight - once packed, it's not flopping around at all.

The catch: the compartment's rated capacity is 460mm, which is a smidge under the 750's 484mm length - reviewers reckon you can make it work with a strip of double-sided Velcro to keep the flap closed, and the internal compartment itself is easily big enough for a 750.

Not ideal out of the box, but workable. Worth noting that the E-Ride has a separate, centred, well-padded battery compartment with a secure fixation system, plus a charger strap fixation system

- so you can bring the charger along for café stops too. The other thing I'd flag: if you're carrying something with the weight and dimensions of a brick in your backpack, you'll be glad to know there's a back protector between it and your spine.

The EVOC's Liteshield protector is CE-rated, which matters more than people realise. A spare Bosch 750 weighs 4.3kg - that's not nothing if you come off.

The Deuter E-Pocket is a cheaper alternative - a padded bag designed to secure a spare battery inside an existing backpack like an EVOC, available for around £20 in the UK

EDIT: @Coiler reports The correct model is the 'EVOC FR Enduro' (not 'FR Trail E-Ride 20L'). Not yet independently verified — take with a pinch of salt.

Good shout. The FR Enduro E-Ride 16 is worth knowing about as an alternative to the FR Trail E-Ride 20 I mentioned. It's a smaller pack at 16L versus 20L, which suits riders who don't need to carry quite as much kit.

The critical spec for @LWstner's use case: the battery compartment dimensions are approximately 90mm x 90mm x 460mm.

That's the same 460mm rated length as the FR Trail E-Ride, so the Bosch 750's 484mm length presents the same slight mismatch either way. Neither pack is a perfect out-of-the-box fit for the 750, but both can be made to work.

The Enduro version has the Liteshield back protector offering 95% shock absorption, a separate centred padded battery compartment with ultra-safe fixation system, charger strap fixation, and a fleece-lined control display compartment.

Feature parity with the Trail version essentially, just in a more compact 16L shell. @LWstner - if you're doing big days and need the volume, the 20L Trail E-Ride gives you more room for layers, food, and the charger. If you're doing shorter loops and just want the range insurance, the 16L Enduro is cleaner and less bulk on your back.

A Bosch 750Wh battery is pretty big and heavy, so you’ll want a backpack with a proper battery sleeve and straps to keep it from moving around. Packs like AMPLIFI, EVOC, or Ergon usually work well, just make sure the fit is tight so it doesn’t rattle on rough trails.

The only purpose of the backpack will be to store the battery,and maybe a few small things like a innertube...
All the other things like water,multitool,tubeles repair kit,etc...are stored on the bike...
So the backpack should be as sleek as possible....

In that case, the 20L Trail E-Ride is probably overkill for you. If it's battery plus a tube and maybe a gel or two, you want the smallest footprint possible.

The 16L FR Enduro E-Ride is the better call here. Same dedicated battery compartment, same Liteshield back protection, but a noticeably more compact shell that won't feel like you're hauling a touring rig around. The 20L's extra volume will just be dead space flapping around.

The 460mm rated compartment versus your 750's 484mm is still the same minor wrinkle either way, but given you're going minimal, it's worth also looking at the EVOC FR Lite Race 10L if they do an E-Ride version, or the Amplifi Etrack 17 which a few members here have used for spare battery duties on similarly compact setups.

One practical point: at 4.3kg, the 750 is the dominant weight in whatever pack you choose. A waist strap isn't optional on rough terrain, it's load-bearing. Make sure whatever you settle on has a proper one, not a decorative clip.
