- Apologies if this is obvious but just trying to pass along some past Mundo-think
Flex in the long narrow sideloaders isn't in itself bad, it just needs to be appropriate for the inherent dimensional stability of the internal cells and the flexibility of the cell interconnects. Something like a long naked Headway battery composed of Headway plastic spacers and bus bars or cylindrical cells with spot-welded bus tabs will do badly with much flexing. But, break this into several smaller bricks with internal stiffeners then interconnect those with flexible wiring, and all is well.
So - the plan seems to be to do the best we can with the twangy sideloader nightmare and then package up cells appropriately instead of necessarily relying on dimensional support from the decks...
On another front - here's a little anecdote that you can make of what you will:
I am temporarily using heavy plastic toolboxes for battery enclosures with flat plywood stiffeners in the bottoms. They are quite sturdy and are rigidly affixed to the sideloaders. A couple of weeks ago I ran over a 1" stick about 24" long on the roadside - no big deal for fat tires. Except this time The Evil Spirit of Jousting caused the branch to leap up and jam between the immovable Earth and unstoppable front of the right battery box. A split second later I had a thoroughly impaled and shattered battery box
. Fortunately the boxes are intentionally oversize for battery experiments and the upper impaled 1/3 was empty of vital organs...
Definitely a freak accident but it brought home the increased vulnerability over frame packs -- sideloader packs can do with any help we can afford to protect them from bits of the world that will inevitably get in the way.... (e.g. Kiwi's
steel ammo boxes)
