BININIU Accessories Battery Compatible for SRAM-Red-Force-etap-Rival-AXS-GX- XX1-X01-eagle Battery Charger Power for SRAM Front/Rear Derailleur/Rockshox Reverb AXS

Anecodotally these seem to be very close to the original batteries that I have. On a seven day bikepacking trip (80% off road/wild camping) in colder (4-13 degrees) weather i've gone through 3 batteries, 2 original and 1 of these, which I installed on day 6 and it lasted me at least until the end of the trip and then the final bits after 18 hours of trains to get me home. I never did check how much was left, I use it still in rotation but I only have SRAM on a gravel bike, which is not my main bike. I came back hear to consider buying another one, as I've built up a new MTB with Eagle XX, and thought it would be good to carry another spare as I a plan two week winter MTB trip, with few charging opportunities.

Not had long enough to give a full review. But seams to do wot it’s meant to

I have been using this battery for a while and had no problems

Slightly cheaper than the genuine SRAM version and works just as good. No connection issue, probably get between 15-20hrs ride time with it.

Well made and identical to the Sram battery . Works perfectly with Sram Gx Axs

So it fits like a SRAM battery & operates the derailleur. Unfortunately, the one I had ran out of charge after two hours. I figured that I maybe hadn’t charged it up enough, so I had a second try. Again, it ran out of juice at around two hours.Perhaps I simply had a poor example. Nonetheless, with the cost being not an awful amount cheaper than the real thing, I bought the real thing.

Fitted to my Sram Etap groupset and it works perfectly. Cheaper than the OEM battery so it's a no brainer I guess.

how long will this last but looks perfect, fits and charges great price
