    Parts for Shimano E8000 motor - lead from battery to motor.

    Thanks but my issue is motor side. The neg pin and cable from motor to that pin is broken. I am going to get a complete pre wired male / female set of connectors and totally replace the proprietory shimano plugs battery end and motor end. Will have to seal motor end as the new connector won't...

    Bought a second E8000 motor

    Did same thing for my merida, just in case. Problem is the warranty is 2 years from purchase so may never have any left when I fit the motor.....

    Parts for Shimano E8000 motor - lead from battery to motor.

    Thanks guys for all your efforts. I am helping a friend with a similar issue. I have pulled that plug from the motor and can see that the positive and negative power cables have melted the insulation and shorted. I have proved that luckily no permanent damage to the motor as I bypassed that...

    Solo e biking. Who has an EPIRB or other safety device to call for help? What are you using ?

    So the ACR resqlnk no longer made as the manufacturer folded. I eventually went with the rescueME PLB1. On special not that expensive. Need to go thru through registration process and single use in the case of an emergency. Basically a last resort if on my own or anyone in a group ride needs to...

    Shimano Junction Box Functionality

    The EN100 serves another critical function.... it provides Bluetooth connectivity so you can get data to garmin devices, connect to the bikes components via etube etc.

    Display unit on new Merida EP8

    Thanks for the feedback. The Bluetooth connectivity comes from an installed unit from Giant. It allows connectivity only via the giant ride control to phone. It is not in any way shimano related. Havnt located it yet but doesn't plug into any shimano ports. That only has assist mode switch...

    Display unit on new Merida EP8

    Ok let's throw a spanner in the works. Firstly thanks for all the info supplied and on the surface and based on shimanos docs all appears correct. But... I have recently bought a giant Revolt which uses the EP8 and pretty much all shimano gravel components incl di2 etc. The only giant...

    Battery life

    Y Yes but Max assist level..... range per charge has too many variables to be meaningful at all. I am more interested in the longevity of these batteries. The marketing spin from shimano for example has been claiming 1000 charge cycles before noticeable degradation!!!! I call that an outrite...

    Interested in average range you get and how many wah is the battery? Assuming a syncdrive sport or pro motor?

    Battery life

    Oh I should mention that my bike has been derestricted from pretty much new so provides assist up to final gear ratio which is around 46kph. Some ride stats below. This is not my usual type of ride. Normally full enduro, today was gravel trails no real tech and more about getting the kms done to...

    Battery life

    Ok so some data from today's ride. When this bike and battery was new, the possible (estimated) range indicated on eco was 100km. I havnt looked for a while but fully charged this morning it now shows possible (estimated) only 89km so a 11 km reduction. After a 60km ride today with approx 70%...

    Just finished and took some readings. Will post when I have recovered ? a few interesting figures. Waiting for battery to recover too before I charge it. Took it to red and until motor said no..

    Battery life

    Good idea and has some merit, less so with lithium but I will try today as have a long ride planned this morning and can easily fully discharge it. Just got to time it just right ???

    Battery life

    Interesting.. so 1000 cycles or 2 years.. so does that imply age is also a factor or was he merely indicating warranty period. As I am at approx 52 cycles after 2 years and 90%. Love to see how many riders would hit that 1000 cycles in 2 years ? if you use a rough guide say average of 40kms per...

    Battery life

    A good question to anyone out there is has anyone hit 70% or 60% yet? What kms and how many charge cycles? And more Importantly has your actual riding range on a full charge reduced by 30 to 40%?

    Battery life

    Your maths may be correct if you actually believe the % values and cycle counts that the BMS is showing... so yes if I had only 1 battery you could guess that it would now show 80% after approx 102 cycles and 7411kms. But remember the kms per cycle I get will be very different from someone else...

    Shimano Battery Life Poll

    Would be very interested in the feed in figures. As you said these numbers may be a guide but also might be meaningless. A real test would be to ride a set distance with as many things being equal as possible from a new battery and then at various points in time do exactly the same ride as your...

    Battery life

    I know an old thread but thought I would add my data to the mix. E8000, EC-E6000 charger. 2 x BT8010 batteries. Generally warm to hot climates charged at around 25 to 35 plus celcius. Never turned charger off during charge cycle as I let it auto shut down every time. Both batteries used and...

    Shimano E8000 ST Unlocker..now bike doesn't work

    Yes I think the Bosch pro chip after its fitted allows you to adjust via the phone app.
