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.
