i store two of my NiMH batteries in the pockets of a pannier bag. i've just cable tied them to the frame by drilling holes through the bag wall.

How do you secure yours?
 
Wood boxes, metal brackets, hose clamps, duct tape, glue, nylon and velcro.

But I've torn it all down to construct two much smaller, more modular boxes I can easily swap between EVs, or store in the fridge when not in use. And I'm load testing and resoldering every cell in a more current-balanced, symmetric configuration. One cell out of the 150 I've tested so far was a dud.

Or a rear seat-post rack .

Someone posted a link to a site called " MEC " not long ago and a link to a triangle, frame bag. I got 2 on the way, but mounting batteries Inside the frame is my preference when possible.

I think Forsen USA is selling triangle frame battery bags. Wouldn't the batt pack just bounce around inside the bag?
 
A great idea for a thread, battery storage can be a headache. My Xlyte 5304 came with the Topeak rack and pannier bag to hold the 4 12/12 SLA bricks and it worked briefly. The weight of the batteries was tearing the stitching out of the bags and the angle from the kickstand was allowing them to favor the left side causing the bike to be a little out of balance. Plus, a rough sidewalk would cause the bag to bounce a little pulling the battery connectors off the battery.

So, a set of pannier type wire baskets were purchased and installed and the Topeak went on eBay. The pannier bag fit very well but within a week or two the the rough sidewalks would still pull the battery connections apart. I wrapped a small piece of two by four in a terry cloth towel and put it under the bag in each basket to raise it slightly and now it works great. The stress on the bag is gone and the battery weight is all on the basket.

On my next project they will be inside the frame...

what about battery theft? how do you prevent that? my barreries are £90 each.

my frame came from an off the shelf ebike so i have a lockable battery box for one of my three batteries. the other two sit in panniers and cabble tied to the frame. this also solved the problem of the batteries bouncing around and wraping the cables up.

when i had sla's they were so heavy they tore threw a good set of panniers.
 
i figure you can't stop a determined bike theif. you can only slow him down and increase the amount of tools he needs to carry :(

Agreed -- great thread idea. Mounting the darn batteries was, unexpectedly, the most difficult part. I've had to reinvent my bike more times than Madonna reinvented her bra.
 
I used an entirely velcro solution. I made a platform out of 3/8 plywood, and put velcro onto the bottoms of the batteries and stuck them down. Then I used velcro straps (available aat Home Depot, Lowes etc.) to wrap around them to add downward pressure.

The controller is also stuck to the front of the batteries with velcro.

It's great because I can take it apart very easily. It's bad because a thief could take it apart very easily.

monster,

what sort of bike are you running and how far do you need to go?

My pack weighs 5KG and gets me past 28KM at 35+KMH. It forms a U shape that fits over the frame like a saddle and is secured with 2 inch wide velcro. Its removable in less than 5 seconds and is not too heavy to carry however far the walk.

Just curious why you need so many batteries!

My Mongoose moto-x had SLAs secured with velcro, very similar to the way Beagle does. I would take the batts indoors to charge in the wintertime.

Now, the 24V Ridgid lithium drill-packs I use, are in a soft-case: over the shoulder, in the back baskets or on the handlebars; depending on my mood/needs. (4kg.)

(spade connectors have been replaced with 4-conductor trailer connectors)
 
Two angle iron rails suspend the bats. Ends of rails linked by very heavy stiff wire. Multiple straps reduce any swinging or bouncing. Lower end at back rests against a chunk of padding (heal of an old running shoe.

The whole mess gets covered up with a reddish wrap of nagyahyde (sp?).

Four 12ah AGM = about 35 pounds . Also have powercheq's stuck to top of bats.

The bike is a tandem. with Crystalite #408 front
