[Teardown] Sram AXS Battery Charger

Ever wondered what’s going on inside a SRAM AXS battery charger? I did too—so I cracked one open to find out.

I originally planned for this teardown to be nondestructive… let’s just say I'm out 55 bucks.

One thing I noticed was the labeling of the battery connectors (pogo pins).

The top being positive.

The bottom negative.

And the right being "T" likely used for battery identification, thermistor, or communication

The last photo shows the battery pinout.

The first image shows the screw hidden under the product information sticker by the sneaky Sram engineers.

The second image shows the other side off the bottom side of the charger.
