LTWOO eGR

Rapid drain or charge status failure


I did get my eGR remounted properly in the seatpost (vs external before) of the new (to me) bike. Thanks for the advice earlier. So much nicer looking that way.

BUT, I got an unhappy surprise on my ride today when it died.  I last checked via app about a week ago and it showed 65% I went on a 41 mile ride and hung it upside down for a few days. Went out this morning and it died 2 miles in. Once I applied power and could reconnect it was indeed at 4% dead. 

So it appears that one of two things happened:

1) 65% indicated is erroneous and should be considered very low. FWIW, I reinstalled it showing 74% and did not charge at that time. 71 miles later it showed 65% which seemed pretty reasonable. Deat at 112 miles. (I don't have shift count but that 41miles in between was a heavier than average shifting exercise. Note: I took the 'bring your own battery cell' approach when ordered. So I'm aware that a different cell than the manufacturer calibrated on (even in spec) could be the problem. But I suspect a lot of people buy it this way since the LiOn shipping costs are so high.

2) A wild theory: Hanging it upside down for storage keeps the motion-sensing RD alive and drains the battery. PURE THEORY but it seems possible.

Does anyone have thoughts?

1) This may be dependent on your battery. But I can regularly get MANY more than 112 miles out of a charge. Also, 65% is not anywhere near dead for me. Again, assuming your unit is otherwise not damaged, it could be that your battery cells are responsible for this.

2) I can't speak for hanging "upside down", but I sometimes store mine by hanging it 90deg against a wall (hanging it on a wall by the front wheel) and I have not experienced any draining.

I just got back from a weekend bug out in the desert. I threw all of nature at my LTwoo EGR and the groupset held up like a champ. At this point if people are having issues with their hardware, please just use your local bike shop! Blows my mind with all the whiny cyclists on this forum who start raging when life gets a bit difficult!
