Help! Battery Mounting Ideas

[Wayners]

Interesting thread this.
I have a wisper frame and need to find away of mounting a 48v battery.
Think I'm going to build a rear rack some how with aluminium riveted together.
Don't like the idea of a seat mounted battery as a bit high?

I think a seat post mounted battery would be ok when you were riding it, it is just below your centre of gravity. Not so good for pushing it about and putting it away.

Would a downtube mounting be possible ? If not then rear rack as low as possible and as far forward as possible. There are plenty of batteries that are available with a rear rack built in

Woosh do a 48v one with Samsung or Panasonic cells or

You can fit any Hailong/Shark/Supershark/JellyOctopus shaped battery to a rear rack, I did: bolted through rot proof lightweight (but poisonous) pallet wood and the battery mount, through strips of aluminium on the underside, held on with locknuts. Or you can bolt through aluminium instead of pallet wood; more expensive. Trouble is you lose some of the utility of the rack, unless you can find pannier bags which fit over the battery. Turns out the cheapos can do that, but they're not terribly waterproof... however, you can buy a waterproof pannier bag cover. Mine's bright orange. My original plan was to make a lockable rear rack aluminium dayglow shark fin battery box with lights and frickin' laser beams, with room for sandwiches. Too heavy. Even with lightweight sandwiches.
