Updating on testing of Di-2 with NMH battery in stoker seatpost.
Asides from a couple minor issues listed in our previous post, at just over 1,000-mile mark, had to fine tune rear shifting a tad.
At 1,325 miles, the green little LED light by handlebars started flashing every so often when shifting, indicating battery life was going down.
At mile 1,360 our front derailleur ceased working, but rear worked fine; indicating it's time to re-charge pretty quick!
According to the manual a red blinking LED light was supposed to activate before that, but that did not happen.
Guess that's why we refer those those little LEDs as 'idiot' lights!
Hooked up charge unit to the little 'tail' under stoker's saddle for 3.5 hours.
Checked battery with voltage meter and decided to keep trickle charge going for another 3.5 hours tAttachment 277781o top off the battery.
So far so good . . . and we are still very pleased with the performance of the Di-2 unit.
Pedal on TWOgether!
