Display and Battery compatibility

[Andy1865]

Hi all, does anybody know if the S900 lcd display will work correctly with a 52v battery?. The motor is a Bafang 1000w geared hub.
Thanks.
Andy.

Bafang 500W with S900 display - works great but two questions

I have just assembled my first ebike kit - 500W Bafang front hub, 48 V battery and S900 display (not SW900) and Jueshuair JSM422A controller. I have a couple of questions. 1) Everything seems to be working great except that the S900 doesn't display watts. Instead it shows Error 000 all the...

So does that mean it will work with a 52v battery also then?

Check the manual!

Only says 36v or 48v, but the controller is rated 48v, so it could work???

I want to say yes, but I found this.

Issues with S900 LCD - Electricbike.com Ebike Forum

Help needed. I recently changed my battery from a 36v to a 52v on my Ecotric Fat Tire bike. This bike has a s900 LCD and a controller that can handle 24v/36v/48v. When I put the 52v battery on I get Error Code 09. On all of the documentation I have found online it says that it is a problem with...

That’s not a rare error code. Sadly that may be a controller issue AND a display issue.

Bafang shipped a bunch of controllers that posted error code 07 or over voltage. AND the early displays wouldn’t show accurate battery levels.

I’ve personally run large 52V triangles in 52v and 48v. A BBSHD was really quick with both voltages. 52v was slightly faster @ 33MPH. 48V 31MPH. But with two different cells. The 48v used cells not best suited for a BBSHD. There’s a difference of about 300mah per cell in the 48V.

Oh, and that goofy post from Luna’s forum.. 36V to 52V. Makes no sense without knowing what motor that was tried on. Some controllers need a firmware change or to be programmed for the rated voltages.
My favorites are from Grin and they re easily programmed in OS X, Linux or windoze.

My controller is rated 48v, but my battery is 52v. I current have a C961 display attached, but i do like the S900 as its more informative.

C961

Most reliable. I still run 961s from 2014. I go riding not watching pretty screens. Less is more for me.

I have the error code 07 in my advance setting. What does that mean. I am disappointed in the pedal assist, even at level 5. I don't see anything in the setting that could bump it up. I did that on my Magnum and it is a 'beast'. But, that is what cadence drive seems to do. howard
