    If the battery didn't catch on fire, AND if the BMS didn't fry, the problem might only be a short in the wiring at the connector end.

    Very carefully removing the rivets might allow you to remove that end plate, and access the wiring inside. Keep in mind that if you are dealing with a charged battery, that is a BOATLOAD of dangerous potential energy. If you are not comfortable messing with something that can short, and burst in a spectacular looking fire, I HIGHLY recommend you find someone to help you safely open up the battery and diagnose the problem.

      Hi , I got your BBSHD version B controller, works great, except the throttle is too touchy
      I blew my original controller when I tried to program it , code 30
      Is your controller safe to program , even though its the new version ?
      It seems the factory new version controllers can not be reprogrammed , do you know if that is true ?

        If you got a genuine controller from us yes it can absolutely be programmed. I don't know where you got it but a controller shouldn't throw error 30 from writing a few config files. Typically that would mean that some mistake was made either in production of the controller, production of the program cable, or in the attempt to use these, i.e. stuff like plugging/unplugging while writing to the controller.

      Could have been a problem with the cord from amazon I suppose . I think I,ll throw it out. , to be safe
      The controller I wrecked was the original one that came on the motor
      I wonder, if I could send it somewhere to be fixed
      I will order a cable from Luna
      I am very happy with the one from Luna , just want to dial it in to me

        Usually if a controller was damaged enough to cause error 30 it would not be repairable. One thing you could try before throwing out that program cable is replacing the harness. But that really depends on if you just noticed this around the time that you programmed it, or the error popped up immediately after attempting the programming. If the latter then yeah it's probably not going to be repairable, if the former it could just be the harness; error 30 is a communication error after all.

        I did try a harness , no luck
        Bike ran good untill my attempt at programing, code 30 right away
        Old controller goes in junk pile

      Hi,
      I'm trying to adjust the sag on the Fast ace BDA53RC 450 LBS/IN rear spring on Sur-ron X black edition. I noticed it is rubbing against the suspension rocker arm linkage, it is making adjustment difficult.

        I bought my wife the KHS 500 Deluxe Fat Ebike last summer. It has a whole 44 miles on it. We took it camping last weekend and put the charger on it at 100% for the trip as it had not been ridden in a while. It did not take a charge and thought it was great that it held a charge. The battery lasted about 15 miles out of the 19 needed to get to the brewery and back. The display shut down at about 52V and would not turned back on. When we got back to the camper, I charged it for a while and the display came back to life. I charged it to 100% when I got back home and it is now at 56.5V. I expected it to be at 58V.

        Is there something wrong? My older KHS 500 has been in the mid-40V range without a problem.

          Open a ticket with Luna from their site. It will ask for the order number so if you did that online look it up before you start the ticket process. Also check on the bottom of the battery pack itself, units that recent should have a sticker on em that I presume is a serial number or some sort of date code that may be helpful to them to identify when that pack was made.

          I also included some basic details of how many cycles it had made and how I followed the break in process along with how I typically used the pack. I'm not sure that is required but I figured it may help them understand the problem. They will respond back to you asking for some specific tests in a specific order to help them identify the issue with that pack. Once they get that information back from you they will usually offer some sort of solution. Since this is now past the official warranty these are handled on a case by case basis and every case is different but so far people seem to be happy with their offers.

        It is my understanding that the output voltage at the 3 wire plug that powers the brake lever cutoff is 5 volts. If so, does anyone know the amp reading?

        Thanks.

          It may help if we knew what sort of a controller you were dealing with and what you are trying to do. I believe the 5v is available there for use with a hall sensor which not all levers and sensors use, some are just a reed or mechanical switch. I'm sure they are all solid state devices so something like 250ma would be on the high side.

        Thanks for your reply. Thinking of making a patch to use this 5V 250ma as a charge current for a Garmin.

          Unless someone else knows for sure I don't think I would try and use any of those ports for something like a usb charge port. There are some power converters out there that can take 52/48 down to 12 and 5 but they are not tiny or cheap so for the specific use of USB port seems like the displays would be the cleanest easiest way to go. Note for future builds besides the display there are some battery packs that have a USB port on them.

        All of the 7 tandems and 4 trikes I have converted to mid drive are from Luna. This set up is on an BBSHD with one of your hard case 52V 17amp battery.
        Thanks, Bob.

          Nice, sounds like quite the fleet.

          Have you considered a display like dpc18 or 860c? Those have usb ports

          Thanks Paxtana. I will look at the two displays you noted. A lot less work than putting together a patch cable.
          It is 'quite the fleet' and enables our older riders who have yet to go the eBike route to draft along and maintain a tight paceline. At 25+mph those with eTandems do a lot of 'motor pacing' with singles who are training for our local Senior Games. It is better than being stuck behind a moped.

          If you do upgrade the displays I would guess you could resell the old ones especially if they were the nicer units. There are always people looking for an upgrade or spare.

        Hello all - I am new to this site and ebikes in general- I did a search but didn't see an answer to my question (though I thought I would...)

        I just got my Luna Fat Galaxy with the Ludi option and a 750c display and am really enjoying it. I do find that I am often wishing for a little more boost when I have my controller PAS set at a 2 and a little less boost when it is set at 3.

        I do enjoy peddling, but I often find that at a setting of 3 I am going faster than I want to at the high gears or if I down shift to limit the speed, the assist provides so much power that front sprocket is spinning too fast for me too keep up with comfortably .

        I think it would be fun to be able to tune the levels to my riding style and size (I weigh 265 lbs)

        Is there an easy way to adjust the power at each setting through the display settings?

        Thanks for your advice.

          I think you will like it when you get it set to 9 steps. You sound like a very similar rider to me and at first I hated it, it was either not enough or too much when it was on 5 steps and I was ready to dig into the programing cable but as soon as I went to 9 I have never bothered to mess with the cable.

        Hi, I'm following Rodney64's thread and I note that his Specialized Enduro is a large frame and the battery fits. I have a 2009 Specialized Enduro Expert, medium frame. I've already tried my lower profile EM3ev 48V (13S4P) Super Shark Ebike Battery (96mm high x 368mm long) and it does not fit. Does Luna have a 13.5/14Ah battery that will fit inside the frame?

          Sorry we don't really have specific information on stuff like that, unless it is already on a build thread it's anybody's guess.

          You might try the PDF mockup of our Wolf battery, on the Wolf listing. It can usually install into smaller areas than shark. If nothing else you can usually install it on the underside of the downtube.

        Hello, I have Luna BBSHD off road w / Dire wolf kit that just wont fire up. I've obviously missed something I've gone through the troubleshooting guide. checking connections, replacing main wire harness and display (500c) which i just received from Luna very quick shipping, Thank you. checked speedo spacing . I made a jumper to power the motor with charger in-which it did run. both Displays will blink on for a split second then go blank. I tried to bypass with the programming cable, nothing. I just can't seem to connect the dots, maybe the controller??

          Did it ever turn on, or is this a new build?
          Have you tried plugging into the other discharge port on the battery? Please try that and FIRMLY plug it in. Sounds like some power is getting to the controller but not enough to power it on. Which could be caused by something like only partially plugging into the discharge on the battery and burning out the antispark resistor as a result.

          If you got voltage from the battery and you have ensured you have a normal, good connection to the controller, then you may indeed need a new controller.

          Thank you for the reply. The build is a year old and ran great all last summer. I was getting it ready for the spring. I have used a a multi meter on every connection point from battery to the motor, voltage is 57-56. I do not know what the voltage is supposed to be coming out of the controller. Thank you again, Ill order a controller and try that.

        While examining the connections under the side cover of my X1 I noticed the 8-pin higo/julet connector was loose. When I explored further the connector unplugged way too easily and on the harness side all 8 pins were bare with no shield or casing. Is this normal. When I looked online for similar connectors I found that a similar connector has a formed shield on the end. See pics. I turned in trouble ticket (order# 146790) but didn’t get a receipt email yet. Is this cable an item that can be ordered or provided?.

          Thank you....I figured you were backed up on the trouble desk and I figured you would want to see the pic (didn’t see a way to attach a pic to ticket)....I had already checked the receptacle for the remnant but didn’t find anything (it’s the one in the 2nd pic) that’s what was so odd and what prompted my question....anyways thanks again, hope to hear from you on a replacement path... Best, Steve

          My tech just confirmed it should have a shroud so yeah probably broke of and fell off somewhere along the way. We will get it sorted out.

          Thanks Luna.....your support team was able to source the harness .... great service Luna!.....Thanks again, Steve

        I have a Luna 750C display that just started to flash on, then immediately off when trying ride my bike. It has a BBSHD motor and a Shark 52V battery. The charger says the battery is charged.
        Any thoughts?

          I would use the troubleshooting guide on the knowledge base to determine if it is the display or not, by either using a different display or bypassing the display with program cable or jumper. If you determine it's the display then it probably needs replaced. If you determine it's the controller that probably needs replaced instead. If you determine it's power issue then you might need to adjust the contacts on the bottom of the battery

        I just completed installing a Luna Bafang ultra kit on my wife's Catrike. It's worked great for about a week but now there is no speed output to the display, it shows 00.0 mph no matter how fast I go. It also has a much diminished power output and very little assist. All assist levels are about the same. I can't believe the cable would go bad in one week. Do you have any idea what may be happening? Is there a known speedo problem with the G510? Thanks in advance for your comments.
