Hello everyone, my first question here at this cool forum.
I have a Mountain Bike with Conversion Kits BL-36 Brushless, 36 volt system.
I am looking for ways to increase uphill power and speed.
I was reading the ebikes.ca web site and they mention that 36V Controllers can handle 48V batteries, strange no?
Here is what they say: (http://www.ebikes.ca/store/#Controllers)
"Voltage Rating
The controllers labeled 36V have a low voltage rollback of about 29V, and can be used with both 36V and 48V battery packs. For anything above this, such as 60 or 72 Volts, you will need to use the 72V controllers which have 100V mosfets and also have a 29V cutout. We have also ordered 48V 20A controllers that have a low voltage cutout of about 39V for systems known to be running 48V batteries. So if you wish to run a 48V system, you now have the option of either ordering a 36V 20A controller or a 48V 20A controller."
Has anyone tried the 36V Controller with 48V? Any other alternative for power increase at small expenses?

Firsthand experience here. Ebikes.ca deals exclusively in Crystalyte, which is different from the BL-36, which is a Wilderness Energy brand kit. I've run a Crystalyte 408 at 48v using the 36v/20a controller, there aren't any problems at all. You can do the same for the 407 as well.
I know that the Wilderness Energy kit motors can take up to 72v successfully, but from what i've heard the standard controller that comes with their 36v kit won't take 48v. You should check with your distributor because it might, but just to let you know its not the same controller that ebikes.ca is referring to.

Pengyou,
my lazy ass wants to seat, push a button and get home! Hehe. That's why I am reading this "Electric-Bike" forum and not the "Professional Bikers - Run 1000Km in one day" Forum.

Abneycat,
I was wrong about my conversion Kit. Initially I was going to buy a BL-36.
I looked in to the controller and it's actually a Crystalyte 36V 20A. Sorry for the confusion.
I couldn't find out the Motor Type that I have, is it written anywhere in the hub motor?

If you haven't taken the stickers off or they haven't fallen off, most of these Crystalyte kits have 2 stickers on them at purchase:
1. A little red arrow indicating spinning direction.
2. A little white sticker with 3-4 characters on it. It'll say something like 406, 408, etcetera.
Do you also have a bill of sale or can you call your dealer and ask which one it was?

I stopped by Power in Motion, a dealer in Calgary during my lunch break and Test Drove the 48V Battery in my own Bike. It goes 20-25% faster and has more torque going uphill for sure. My motor is 408, the white sticker is still there. So, I guess the solution now is to invest on a new 48V battery pack + Charger.

Ahah! Power in Motion, yeah. Thats where I got my first kit from actually. They're pretty centered around selling the 408 to most people. Not that thats a bad thing, the 408 is well suited to the Calgarian environment, particularily if you travel between the downtown core and areas like the Southwest.

And carry more Ahs aboard too maybe. Higher speeds, faster climbs, more showin'off... Y'all will need more energy aboard, no?

This is Ken the owner of Power In Motion. Well, it looks a few members had checked it our store. We carry BL-36, Crysalyte, and bionx conversion kit. We try to find the most suitable solution for our customers.
We recent testing out the dual Lithium configuration. This is best configuration that we together. We use two 37v Lithium batteries. We connect both of them into a relay switch. The switch allow the battery either in parellel or serial. When we run them in parellel, we double the amp, which double the distance. When we run them in serial we double the speed. So for a 408 motor, we will hit 58km/h at 74v. When we switch back to 37v, we will get 130km in range on flat without pedaling. This is most flexiable configuration then any other setup we have see. We are hoping to have demo bike ready in the next 2 weeks. I encouage you to come by and see how our relay switch works and the configuration. We should have some video will be posting onto the youtube soon.
