BMSBattery 48V500W 393RPM Versus Cellman 8T

It's nice to go fast but what kind of hills do you have as this slows down a higher speed motor and taxes the battery. Hills need a lower speed motor or will get hot.

One other thing. The cellman controllers are the same as ebike.ca controllers?

Do they offer direct Cycle Analyst compatability? And what would be the wisest cellman controller selection?

I will be running 48V

Thank guys

Both ebikes.ca and cellman sell infinion controllers. That does not mean the plugs match or that they are programed the same. Cellmans infineon is matched to his kit.

I'm still green when it comes to bike controllers so take my opinion with a grain of salt. If it were me then the infineon 12fet with 4110 fets would be my choice.

Wurly: I will be running A123 batteries. Running at 48V requires 30-40amp continuous for 30mph on flat ground? So then i would need a 12Fet controller?
How many amps is the KU93 good for? This is the BMS 9Fet version yes?

999zip999 : I know that i said hills but to put it into context, i looked up an elevation profile of my route. My finish point is 16Feet higher than my start point and the distance is 12.5 miles. However i have a few small hills on my journey. 4% grade for 200 meters and 3% grade for 200 meters. So small enough for the MAC 8T to deal with i should think.

atom1025: Why exactly would you go for 12Fet? Is it not a little to much for my requirements?

I have made up my mind for the MAC 8T Kit. I reality i would like the battery in the triangle but the max i could fit is a cellman triangle pack 36v 11.5ah and i am still considering this but i have a price on an Victpower 48v 20ah with the only downfall that i would have to mount it on a rear rack. I am waiting on cellman to get back to me to make my final decision and it would be perfect to order everything from one vendor.

Looking at the ebikes.ca simulator the difference between 48V 20ah and 36V 11.5ah is night and day for performance and range. I would just hope the balance is not too bad carrying the battery at the rear.

I'm making an A123 24s. One 12s in the triangle and one on the rear. Yes get a 48v it wakes up a motor. I fit a 48v20ah. Ping in my triangle. Make a box out of cardboard, battery size. Makes a difference when you have it in hand.

I run my 8T mac (26" wheel) on a 52v a123, controller limited to 25amps or so. I have NO ISSUE getting up to 30mph and holding it. Usually tops out at 32-36mph depending on wind/conditions. I weigh 78kg. I think the 8T is the best choice wind, maybe the 10T if it's quite hilly and you don't need high speed.

.I mentioned 30-40amp as i wasnt aware of the terrain and also a rough guide for 30mph if you cant keep up with peddling at that speed.
The ku93 controller will be ok if it gets airflow.choose a ku123 if you are concerned about thrashing it.I have limited my ku93 to 25amp like i said.Its enough for 30 mph(with pedalling).I did that as i dont want my ping battery to see any more than 1.5c.
I think your biggest decision is what battery and where its going to be on the bike. I would go for 48v , but a 20ah will pretty heavy thing to carry on a rack.
