SRAM AXS derailleur connected to main ebike battery

I really don’t know why… other than that jockey wheel can make some chain noise (narrow /wide), and I was following instructions.

Hello

I have upgraded my 21 Scott Stride eride with SRAM AXS electrically operated derailleur

I like the system (except controller paddle), but would like to upgrade it – replace the derailleurs battery with power supply from main ebike battery. SRAM has such option - the upper version of Scott Patron has these feature as a standard setup. The problem is that cannot find the part numbers of SRAM wire interface. The only what I have found

bikerumor.com

Patent Patrol: Is SRAM eTap wired on the horizon?

Is SRAM's eTap wired system on the horizon? It's possible, especially for the burgeoning population of e-bike riders.

My Scott representative said that battery interface is a SRAM part (not Scott’s) and provided me the part number ( 00.3018.317.000.) but I cannot find it in the net, so either the part number is wrong or the system is so new.

Does anybody knows part number of the interface?

KR,

I have the Trek Fuel exe 9.8 GX AXS and when i bought it I noticed that the wireless derailleur has a wire coming out of the back and going into the frame where the battery should go. I asked the guy in the shop what it was and he explained that trek thought it better this way because A. you don't need to charge a separate battery and B. the wireless SRAM derailleurs keep active when in motion so that when transporting, if you leave the battery in then it will quickly go flat but because Trek wired the power into the main power of the bike then the derailleur is only powered when the bike is switched on. So yeah, if you can do this then I say do it. I don't know where to get the adaptor from our how to wire it but if i find out I'll let you know because I think it's a great idea.
 
At this price it's tempting but does it need switching on by a Bosch dealer?

I checked the voltage on my AXS battery fully charged was 8.4v so it looks like it's a 2s battery. I have been trying to source the correct cable for months now from Trek and SRAM for my Ex-e but I keep getting the run around and nobody can tell me what the part number is. After seeing the cost of that extender linked in this thread I took matters into my own hands and made my own.... So far I have tested it with a bench power supply at 8v and it works great! I ordered a regulator to step down the 13v coming from the TQ smart box to 8v and will wire it in and go for a ride later this week. So far it looks promising. I have my garmin wired in to charge off the bike too from the pogo pins on the back of the device.

Hi! I'm interested in making one of these SRAM battery adapters. I will probably print the full piece, rather than Dremel out a cavity in the factory SRAM port cover. Can you point me in the right direction on what brass pins you used in this project? Did you heat set the pins into the plastic or some other means of attachment? Any photos of the other side of the adapter to show how you weatherproofed the leads? Thanks!
