How to mount the battery pack

[mrhat24]

Hi, I was wondering how you mount the LiFe 36v10A onto your bicycle.  If possible I want to mount it on the triangle bar where the water bottle should go.  However no such mounting system exist.  Another way is to attach it to a rear rack.  I see that the battery has 2 grooves that slides into something.  This is probably one of those battery used on a premade electric bicycle where it slides down behind the seat.  There are a couple of rear racks that has these detachable grooves used for attaching & detaching. 

1st one is a battery mount system used on now extinct tidalforce electric bicycles.

The company that makes these racks is http://www.topeak.com/products/Racks
They make trunk bags that you can slide in & out of those grooves on the MTX rack system.

2nd one is old man rear rack
ativesolution.com has a rear rack battery mount attach to that oldman rear rack to accept the battery.  This method is too costly.

3rd way that I've seen is a picture of a bike on goldenmotor gallery that stored the battery under the rear rack.  I wondered where he got that rear rack from.  Attached is a picture of it.

4th Use a long water botter holder to hold the base and then use velcro to strap it to the bike frame.
Here is a link for the long water holder that can slide up and down to accomedate the size of the water bottle.

I'm trying to avoid using the rear rack as a battery holder because I want it free so that I can attach a big basket on the back to carry stuff. 
Anyway, if anybody has pictures of their system with the LiFe pack attached then please post.
thank you

Lower is better from a balance point of view as long as you don't bang it on stuff.  I wanted to do mine in the frame also.   Had a stable platform built but just didn't think that the water bottle cage screws were up to the task of holding things steady in the frame on a few trails I wanted to travel.  So not wanting to damage the frame nor spend extensive time building decent brackets I spent even more time looking for and modding a tool box to house the batteries on the rear rack. I am into my second and third build now at the same time as well as modding the first.  So like you still looking for the perfect place for the batteries. Ideally I think it would be best to shop for a bike to fit the specific application.  Oh well maybe next time.

I'm using the MTX V series rack and some small bungees from WalMart right now. I use about 6 bungees and the battery is SOLID. The V series rack only clamps to the seat post, but if you get it tight it doesn't sem to move around much.

I think the best battery housing is a 4inch square piece of aluminum exttrusion. They walls are usually a little less than 1/8 inch thick, and since it is an extrusion you can have it cut to any length. Since 4 inches is a bit thicker than the stock plastic case, I am trying to make it shorter. Would like to get it down to about 12 inches long. I am able to obtaain 4 inch square alum exttrusion from our local scrap yard for $6 a foot. All in all, pretty cheap for a nice solid, aluminum battery housing...

G'day all,

I've just received my LifePO4 10Ah battery and was also wander how I was going to mount it. I would prefer to mount it on the frame, but there is no way to slide the battery onto the mount inside the frame. I was thinking of cutting slots into the mounting bracket and cutting matching slots into the battery casing, but offset to that you could simply drop it on then secure it by then sliding it down slightly.

Have a look at how I mounted mine on a standard rack http://goldenmotor.com/SMF/index.php?topic=270.60
