What Rack To Carry Second Rambo Krusader Battery?

[Jim1348]

I have a Rambo Krusader 2. I ordered an additional battery for it. My bike has a rear luggage rack. Are there any cordura nylon bags that attach to the top of a rack like this that would hold a battery? It would need to be at least 18 inches long.

I did find the Kemimoto Lipo battery bag, but I need one a little bit longer. Maybe the West Biking e-bike battery storage bag.

Who on here has one that they like?

I've got this battery bag and my 18" Reention Dorado battery fits inside nicely.

It's available on AliExpress as well,..

The battery bag worked great, but the 14 pound battery broke my rear rack from all the pounding.

That was mainly due to my poor rack design and it's a full suspension e-bike where the rack isn't supported very well.
(It can't attach to the seatpost because of the moving swing arm. )

I've thought about this, and I have come to the conclusion that long term use of a heavy battery in a rack might not be a good idea.
As @PCeBiker suggests, the bouncing around of a heavy battery can cause damage. It's not the rack that is critical, but the battery and cells within that are critical.
I think that I'd rather put a spare in a backpack...

I carry my spare batteries in a pannier, such as this one:

GT-18BP Classic - Convertible Backpack Pannier

Arkel is an ideal option for bike and hike trips / Quickly transform it as a backpack to bring as an airplane carry-on or carry with you.

This keeps the center of gravity lower and the pannier can be padded with extra clothing for protection.
This particular pannier is also convertible into a backpack should I choose to carry it that way. I rarely do it though, since the thought of being thrown off the bike and a flaming battery strapped to my back is a bit disconcerting. This is just me being paranoid though.

Rambo also makes a pannier that will fit the rack you chose:
