    Purchased a wolf pup battery pack, Luna charger, Luna 500C display and Luna BBS02B, 4 months ago and installed it on a bike. Things were great until recently. My last 3 rides ended prematurely when the entire system shut down. Display went black and motor shut off. Would not turn back on. Had to pedal home. Tried to turn it on several times over a period of several hours, no luck. When I connected the charger, display showed 49.7 volts. Same voltage on each of the three occasions. This corresponds to roughly 50% charge left in battery. Battery took full charge each time. Searched your forums extensively and found suggestions to rebalance battery by charging to full charge and leaving it on the charger overnight. That didn't solve the problem. What can be done? I know this battery will run farther down because I've done it several times previously. Getting only 50% out of the battery is not acceptable. Is there a warranty on this, it's only 4 months old? Help please!!

      The voltage you are seeing when charging is not necessarily the resting voltage of the battery, and the voltage under load is certainly lower. Could be hitting low voltage cutoff under load, a small battery will sag more than a larger one. I would adjust the config to lower current to more closely match such a small battery, but if you would like to speak with our technician Seb about any concerns you have feel free to email support@lunacycle.com

    Hi! I'm installing the BBSHD I received this week onto my Trek DS3, with a ~70mm bottom bracket. I'm attempting to attach the Y shaped steel bracket onto the shaft, but there isn't enough clearance between the shaft and the body of the motor unit to get that bracket in place. I haven't found any similar posts, though that might be due to the fact that I don't know the proper name for that bracket piece. Am I doing something wrong here? Thanks!

      Thank you! If you're sending me a package anyway, can you throw the two ends of the shift cable sheathing in there? The ones I would use on the ends I cut to install the shift sensor. If they were included, I don't know where. They weren't in the shift sensor bag. Or if they aren't important, I can just skip them. Thanks again!

      You mean ferrules? That's not included with shift sensors, only the sensor. I would not recommend installing it without ferrules as it could affect shifting performance. Typically you can get these for a few cents at a local bike shop if needed right away. I can not have some included as I work remote and it is not something we typically include sorry

    Will the xt90 and xt90s connectors interchange?

    I just bought a 48 volt Advanced 300w Luna charger for my older bbso2 battery and the connection is the wrong one for this battery. Is there an adapter that we can use it has the three prong output from the charger that will go to the old style plug-in so that I may charge my battery

      Unfortunately you'll probably have to remove that connector and re-solder on a matching one. Most Hobby Shops that deal with R/C cars and drones can usually offer this service for you though. :P

    Is it okay to drill an additional hole on the Luna Wolf Pack Mounting bracket?

      Probably. I can't see it being a big issue.

    Hi, I just did a build with the BBSHD, and the front chainring that was included doesn't have enough of an offset - when I shift into my easier gears on the rear cassette, the chain comes off the front chainring. Is there another chainring with a larger offset so I can use those lower gears, preferably with 42 teeth or so?

    so I just got my 300w advanced charger. I have two packs, the normal wolf and a pup, both 52v. What amp setting should I use for each of these packs?

      For the best cycle life you should charge as slow as you can. If I am just charging after a ride and got nowhere to be, I charge at 1A.

    I have a Luna double torque /double gear hub motor that I have been running on 48v
    i want to use a 52v battery now. Can I do this?

      Yes you can do that.

    I'm interested in small chainring options for the BBSHD. I like the size of the 30T Mighty Mini but the teeth are actually too "grabby". Chain sticks a little as it comes off when exiting sprocket. Maybe due to tooth length?

    Wondering why there's no such thing as a BBSHD 104BCD adapter (only 130BCD)

    Wondering why Luna dropped the Lekkie BBSHD Bling Ring line from the website.

    Know any other options besides Mighty Mini 30T, PrecisAlps 32T, or Lekkie 28T?

    How do I reset the trip mileage counter on the Luna 860c? I thought it would be a simple double tap or sequence of button hold downs but am finding nothing on the interwebs.


    Thanks

      On mine, holding down the "+" and "-" simultaneously for a few seconds does it.

    Does anyone have experience with using the XT-90 to XT90-S adapter, and advice/recommendations on how to waterproof that external connection on a Dire Wolf (or similar type) pack? Are there any other drawbacks of using this set up?

      Dieletric grease is going to be your friend here. You're going to want to make sure everything is properly coated. Also try not to ride in the rain unless you have to. It is just not generally a good idea when it comes to electric bikes. I know many people do it but it is just not worth the risk imo.

    That did it ncrkd!! I knew it had to be something simple.

    Thanks

      I have a BBS02 on my wife's bike and she swears to me that the throttle works even when pedaling. I thought it didn't on the 02? Did I inadvertantly do something real good in my programming?

        Depends on the age of the motor, older versions probably will, if it is newer it may not. We are still working on a firmware fix. Basically bafang changed something and fixing it will take time

        I guess she got lucky, I got the motor from you guys a month or so ago.

      Most of the wiring was straightforward on the controller included with the mini cyclone, but a few were not
      • a red wire with two connections coming off the flat connector that has 6 wires connector - one black two prong, one with green sleeve
      • 1 two prong receiver from the throttle
      • 1 white wire with green sleeve
      • 1 three prong receiver flat red cap with a illegible tag
      • 1 prong connector coming off the power cable

      Also how are you guys connecting the power cable wires to the xt90 wires?

        I'm pretty sure I know which wires you're referring to:

        When you said "green sleeves" I figured you weren't making a musical reference ;-) I'm going to assume instead, you meant the wires with the green translucent rubber shielded plug-covers. Am I right?

        If that is indeed the wires you're wondering about; both those wires are full-system-voltage; that's why they've got those protective rubber "sleeves" on them.

        The white one of those is your phase-wire signal. This sends out a pulsed full-system-voltage signal which can be used for a speedometer, a range-calculating BMS, etc.

        The red wire is used for your power-switch. I am pretty sure both of those wires do appear on that wiring diagram.

        It is best you do not hook any wires together which you are unsure of... In fact--just don't hook anything together at all--until you have thoroughly reviewed the diagrams--would be my recommendation.

        Checking and double-checking doesn't cost anything but a little bit of time... But powering up something with wires crossed, and "letting the smoke out" --can end up costing a great deal more! (says Captain Obvious)

        Best of luck!

        tklop I had not planned on it, I have only connected that which i can confirm, thats why im here asking. That being said, your comment doesnt, nor the diagram for what i can see provides any answers for the questions i posted in comment #3635.2

        I did not receive a power switch aside from the one on the throttle and it has a two prong receiver(which had a connection point) but no place for the red wire with green sleeve or red wire with red sleeve, do i just leave these disconnected? And i see no place to connect the white wire with green sleeve (phase-wire you said), is that one safely left disconnected?
