Hi guys,

This is for a future ebike build as I'm unfortunately jobless at the moment.

I have a bike similar to this one:



I plan on using a lithium kit from ampedbikes and this is the battery that comes with the kit:
http://www.ampedbikes...

Which is perfect for any full suspension bike. But I also want to use my current lifepo4 battery which weighs about 32LBS which is more than most seatpost racks I've seen can handle. So if anyone has any suggestions please let me know.

Thanks,

Vic

I really should take out Patents LOL
I was promoting that battery case design in 2004 and everyone hated it.

As for the Amped Battery Chemistry.

The Chevy Volt and the TESLA are not using the same battery chemistry.

THe Volt is using Li-Po
TESLA is Li-Mn

To achieve only 6.1 Lbs at 36V X 10Ah including case and mounting hardware means the Battery has to be Lithium-ion Polymer AKA Li-Po AKA a BBQ Starter.

I had a similar Soft tail DF Bike (gave it away at Xmas) as mounting batteries was a bitch (I used an Axiom Seat Post Rack) but even with a 14 lb Ni-CD pack it made turning a mess as the rack would not straighten back out after a sharp turn.

Old Man Mountain makes a Rear Rack for Soft Tail DF Bikes that will support your 32 Lbs.

...also want to use my current lifepo4 battery which weighs about 32LBS which is more than most seatpost racks I've seen can handle.

I wonder if one of these could be fitted somehow:


"Axiom Odyssee Full Suspension Rear Rack"... eg here:

...or hang the pack off the handlebars?

I saw some panniers like these the other day that looked interesting:


...but that'd probably mean splitting the pack, which can get a bit messy.

MEC sells a Front Rack for Suspension Forks but you need V-Brakes Bosses which seldom appear on Suspension Forks that come with disc brakes.

To achieve only 6.1 Lbs at 36V X 10Ah including case and mounting hardware means the Battery has to be Lithium-ion Polymer AKA Li-Po AKA a BBQ Starter.

I don't believe it's Li-Po. I definitely don't want a bbq starter where I plan on placing that tube. lol
Although I don't see it posted anymore I remember it saying it was lithium manganese batteries. Also said Samsung was the maker if I remember correctly. Which I know nothing about. So I'm wondering if that's a bbq starter too?

Now for the rack. Yes it has disc brakes both front and rear. The rack Lock posted seems alright. I see the disc brake in the picture.

Thanks for the help so far,

Vic

BTW, Joshua that new display picture is hilarious.

So far I remain confused.

I posed the question to the Power-Assist Group and the answer was the battery pack is Li-Po which sounds about right to achieve such a low weight.

I used to use a 36V X 10Ah Li-Mn from Sanyo that weighed 13 lbs. It is unlikey the same chemistry can be 7 lbs less.

Here they are shown as LiCo's:


Cells possibly Panasonic:

IF they are using those Panasonics then 40 of the Panasonics as 10s and 4p yields 36V 9.8kWh and 1.8kg/4lbs excluding case etc.

Panasonic labels `em Li-ions but their Overview sheet shows they are LiCo:

BTW Ampedbikes are just 10 miles down the road from Battery Specialties who are a Panasonic authorized assembler and stock those cells:

AND BTW Vic?

Is this the outfit yer dealing with for the Ampedbikes product?

Looks like a new Canadian dealer and local too! Yay!

Not dealing with them yet. I did send a few emails to Danny cause I want to buy a controller for my existing bike. The one you saw at our meetup. I want to tinker with that bike a bit. The controller that's on the bike now has under and over voltage protection. 32V low, 44 too high. Kind of struck me as odd. Amped's controllers have a range of 36 to 60V. I have this feeling that the bikes 200W motor can actually be better than it is. It's the only reason I can see why they put over voltage protection in the controller. Wish I knew how to reprogram those things.

Edit: After reading the books that came with my bike again there's no mention of an over-voltage limit. Must have been a dream I had. I'll open up the controller tomorrow to see what it can do.
