That’s good to know. I guess I’ll just buy the Sram battery for a backup.I actually just went back to using the SRAM AXS battery. The MRX batteries were great initially but after about 7-8 months both of my batteries eventually had issues connecting/pairing with my AXS derailleur and dropper post. While riding, it just stopped shifting even though it was charged and fully locked/snapped in. Luckily, I had my OEM battery as a spare.
