Hey Everyone,

This seems to be the biggest problem for me .. I presently am trying to stuff an 8p 24s lipo battery into the triangle of my bike ..

Please post photos of how you custom mounted your battery pack to your bike!

Here is how i did my first build..

i ride in the rain since i have no car. i park outside a hospital for 12-30h at a stretch. therefore my battery lives in one of my waterproof panniers, and comes inside with me.

I put them in a box on the rack the first time with 36V 10ah

but when I had more 48V 10ah I split them and put them in the bottom of the panniers. Next bike will have at least some of them in the triangle.

I bought a couple sheets of Lexan polycarbonate, and used a small torch to heat the areas I wanted to bend, and then folded it up into a pack that holds all the cells tight and secure, and protects them from anything stabbing them. The lexan is strong! I couldn't stab through my tester sheet with a full arm swing with an icepick! Lots of puncture protection for the cells, and a nice secure way to hold the 16 big LiPo packs securely in place in a weight balanced location.

Here is my bike, with a 48v12Ah Lifepo4 pack. I like this arrangement because it is quit discreet.
 
I'm gaining on it...I hope! :p

Also to do: mount the 36/20 PING pack again to its mesh basket, this time with a different fastening approach
as was described in a posting above. Must go to the fabric supply store and get some PVC-E glue (fabric glue):
it will stick to duct tape and will make the final sealing of the Ping pack's wire exits, and also cement the black billiard cloth
to the top and two or three sides of the pack.
It should all look pretty neat when done, perhaps tomorrow. Then: bombs away! I go pounding and flying over rough stuff,
as if this were a rugged mountain bike...yet, it's just a plain old beach cruiser.

Pictures to be applied to this space pretty soon: a basket case withal. :wink:
 
There's a pivot point right behind the blue switch box which is locked in place by an L bend so it won't fall out. When hitting bump in the road the battery bounce a bit at the pivot point which absorb some of the shock. Much sturdier than the topeak seat post rack i used before. The nice beefy Schwalbe Big Apple tires also absorb a lot of shock.

Some data when I get my bike computer running .....
 
I stuffed eight Milwaukee 28V Li-Mn packs in 2s4p configuration in a trunk bag. I had to thin the connectors to make them flush with edge of each pack.

The trunk bag is large but fits nicely on rear rack.

Each serial pair is routed to a fuse block that is located in the right-side pocket of trunk bag.

Here is the latest iteration of the bike.
