Hi,

A while back, I had an issue with a 48V 3A Luna Mini Charger. My battery voltage was low and it flickered on and off while I trickle-charged the battery. After some time, a quick power cycle got the charger charging normally. However, I noticed that since then, the charger only charges to 100% (54.4V) no matter what the charge % knob is set to (usually set at 90%). Please help.

[paxtana]

Those sound like two separate issues. The clicking/flickering needs an adapter. The selector on the other hand.. maybe the knob is messed up or the switch that corresponds to it. Worth keeping in mind even at 90% it is still going to output max voltage, just going to cut charge earlier

[flyinbrick]

I see, just seems to be such a coincidence. You guys did send me an adapter (thanks) and I understand about the charge voltage. More precisely, the charger doesn't stop charging until the battery reaches 54.4V no matter the knob position. The knob clicks normally mechanically so I'll go ahead and open it up to check it electrically. Any other advice would be appreciated. Is a schematic available?

[paxtana]

Sorry no schematic..but if it is relatively recent we can probably replace it.

The magnet mount that came with the Wolf Pack V2 came with tapered M5 bolts that wedge themselves into the magnet mounts holes and disform it if you really tighten them down. Button Head M5 - 0.8 x 20mm sit flush on the mount spreading the torque force of the bolt over a much larger area of the magnet mount surface. I would think they would work better for any application of installing that mount at least that I can think of. I actually just ordered some button head M5 bolts in stainless to do just that. Just a suggestion anyway.

Just realized I probably posted this in the wrong place but I know the right people will see it

I couldn't figure out how to upload a photo so I posted the photos on my facebook and put up links to them

[paxtana]

That's an interesting point. I think we would need to change the hole size on the bracket or source special bolts for that to work though. If the bolt diameter does not match the hole tightly you will have lateral movement which might cause it to work loose over time. The bolt is about 4.89mm and the hole is about 5.65mm so it may make sense to keep it as is for now, and advise to simply check the tightness after a few weeks once it settles in while using the countersunk version.

[pure_mahem]

I see the reasoning. I see how the taper allows for them to auto center the bracket so to speak. However, the button head bolts don't seem to be going anywhere once tightened down. I do use a bit of Vibrex on them though to prevent loosening. I like the increase in surface area from the button heads better though and going a step further adding a washer further increases the surface area. I do see this would probably only increase downward holding force and do nothing for the side to side. I will keep an eye on them for movement and loosening. It is nice to see how Luna has put more thought into even the bolts they use than first meets the eye. Thanks

Did not purchase BBSHD from Luna because it was not in stock. Did purchase a triangle battery however. Installed motor and understand the cabling coming from the BBSHD except for a small gauge wire with rectangular connector. What is this for? It is not on diagrams I have found. This wire and connector resembles the battery voltage sensor wire and connector that connects to the voltage indicator that I got with battery. Any ideas appreciated. Thanks Tommy

[paxtana]

That is for a voltmeter, they are not necessarily always included if we don't have them available at the time but it plugs in to that white connector and just reads voltage.

Bottom Bracket Size Question. Looking to add the BBSHD to a 2009 full suspension Garry Fisher. It has a threaded BB that is 68 mm wide. I will need to add 8-10 mm of spacers to get the motor housing to clear chain stay. This puts me at around 78mm. I would like to order the 68-73mm BBSHD as i have seen 73-100mm versions with a huge gap that needs to be filled with excessive/ custom spacers. I have seen the 68-73mm version work on 76mm in pics with a little room left on the thread.

What is your thoughts on the BB Sized BBSHD for this setup?

[paxtana]

Probably doable if you do without the black lockring (the jam nut) and use loctite instead. It's going to be close though and not something I can guarantee. Take care when inserting it not to scratch the axle on the motor in case you need to exchange it.

[rlc2052]

Thanks for the response!
If I do order the 73-100mm do I run the risk of having to add a lot of spacers to fill the extra room on the shaft similar to this post?

https://electricbike.com/forum/forum/main-forum/diy-discussion/14152-frustration-with-73-100mm-bb-bbshd-kit

It looks like he had to add about 25mm of spacers to get it to tighten.

[paxtana]

Pretty much. See this page https://electricbike.com/forum/forum...considerations

[Bicycle365]

....This puts me at around 78mm. I would like to order the 68-73mm BBSHD ....

Answered your own question, I would not try it as the 5mm you are stealing from the non-drive side is coming out of the available threads to sock the whole thing down. If you put the required torque on it you are doing so on about half the recommended amount of threads. Stripping the body of the unit or the lock ring is highly likely

2nd programming cable is a failure too?
Ordered one with my build back in november and got 2 uses before the connections got a bit loose. After a few more sessions, tension didn't work anymore so I finally just bought another cable. now the new cable isn't doing anything with any software. Windows does have the driver too. Any ideas? Display, PAS, throttle etc all still work great.
BBSHD from Luna, cable from luna.

[paxtana]

Fair enough, maybe the second one's just a dud. It is unlikely to be that the original cable messed up the controller which in turn messed up the second cable. Stranger things have happened but only time I have ever heard of something like that happening I never got confirmation as to the cause. We can probably ship you another cable if it's in stock, do you have the order#

[gas_cars_suck]

I just made sure to download the program with the Luna logo just in case but still no luck. Not sure what else I could troubleshoot.
80875?

[paxtana]

Okay, made a work order and we'll email you tracking once label is created. Please note if this replacement does not work there is not much else we can do, you might need to try on another computer or replace the controller. Probably won't come to that though. Fingers crossed!

[MichaelT]

There are 3 gaskets on the BBSHD.
2 Paper, 1 Rubber.
The factory uses a gasket adhesive when assembling the motor.
What do you use in your shop for gasket adhesive for the Paper and Rubber gasket?

[MichaelT]

I just don't water getting into it and the motor is in a prime spot for that.
Factory sealant used on the gaskets held up properly for 3 years, I want the same results, at least.

[paxtana]

Okay I guess I am not clear what factory sealant you are referring to on the gaskets themselves since all the ones I have worked on only had additional waterproofing done only had sealant on areas such as the phase wires. This is typically a white silicone and probably generic. If you have opened the core it would make sense to add more silicone at these points.

That said, personally if I am working on a motor that has had previous issues with water intrusion I typically go over the edge of each gasket with dielectric grease once the motor is all closed up. Especially along the rubber gasket and along that rubber grommet where the wiring exits the controller. Does not look as nice as sealant but it is more easily serviceable if you ever need to open it up later. I find that while this area does get exposed to water it is usually not like, pressurized water, so even dielectric grease is more than enough to add an extra layer of protection.

[MichaelT]

Both the paper gaskets had glue or sealant applied, both ripped when doing the teardown of the motor.
The rubber controler gasket is only stuck to the core, the ballance is hanging loose.
I guess I'm going to use Permatex Black ATV on the paper gaskets as its oil/grease resistant.
I will trim any extra paper gasket, then use the Permatex Black ATV on the housing gap as well.
As for the rubber controller gasket, not to sure what will be the best to use ....yet.
But whatever I use, its has to keep things dry.

[AA-Battery]

So my BBSHD three button display switch glitched out on me. It's been working perfectly, but the power button no longer works. Rode it last night and to work today perfectly. But when I got to work the power button no longer works. The + and - buttons work fine, but I'm getting no response out of the power button. I checked the connections and pins and they all look fine. Figured maybe it just needs a hard reset so I turned my battery off, unplugged and replugged everything, but now it won't turn on. Could something be causing this or did the power button itself randomly stop working? BBSHD with DPC-14 display connected to a blue 4 pin 3 button switch.

Does anyone know where I can buy a replacement switch? So far the only place that I can find is California ebike but they want to charge me $30 to ship a small packet.

[paxtana]

That is the only source for the switch itself that I know of. DPC 14 is discontinued anyway in favor of DPC-18, at least at luna.

[Timm]

California e-bike is the only source for this part, and many others. That is where I got my switch. Awesome service!

[sur-hart]

Enjoying the shit out of my Sur-ron until this [video attached] happened.

With the key turned to the on position , the dashboard (meter), the front headlight, and tail light will flicker every 35 seconds for 5 seconds and it will keep repeating this for hours. As soon as the flickering stops it dies for 35 seconds the lights go off, the dashboard goes off, the horn doesn't work all of this with the key still turned to the on position.

Turn the key to the off position nothing comes on or flickers/flashing as it should be.
I've searched and searched for answers or others having the same problem but found nothing. This happened after approximately 20 mins of riding around my yard and neighborhood a few days ago. I think I have 140 miles on the bike.

[paxtana]

Hmm..probably an issue either in the wiring or the controller. Presumably the controller unless you visually see any wiring damage from any physical impact, crashes, that sort of thing. Can you email this link and your order# to support@lunacycle.com re:Seb?

[tommyn]

Am considering purchase of Luna Replacement Controller for BBSHD. 850-C display gives Hardware Version as E 2.3 and Software as 2.0B-V2. Can you advise if I need Type A or Type B Controller from this info? Or do I have to take it apart and check the wiring? Thanks
Tommy

[HIGHVOLTAGE]

You'd have to take it apart and check the wiring.

[tommyn]

Well, so much for configuration control. One would think that someone would know the hardware version when the connectors type changed? Oh well... Thanks

[Mopedward]

How can I get my hands on a dolphin pack cradle without the battery? I’ve looked around a little bit with no luck. Maybe I haven’t search enough but any help would be nice, thanks.

[paxtana]

You mean like this? https://cdn11.bigcommerce.com/s-9vkj...114.1562916291

I think we have one, would need to check with shop they still have it though, and handle it as a special order through email.

[Mopedward]

Yes, that’s the cradle I need. If that could be set up I would be very appreciative,thanks

[paxtana]

Okay please email support@lunacycle.com re:gary for assistance with this and we'll get back to you once we check availability

Hey, I see some ebikes sold with an option of either chain+cassette or belt+1/fixed gear.
1) What's the general pedaling experience of a single-speed belt drive? Does it mean that a person basically always need to be in some level of PAS to pedal comfortably?
2) Does this setup allow an installation of an IGH, and is it needed/recommended?
3) Would you recommend a single-speed belt drive for a heavy offroading fat bike?
Thanks!

[paxtana]

The Fixed is not actually a single speed, it has a 3 speed IGH. I assume it was named Fixed because it gives off that kind of simplistic vibe but it is not a single speed 'fixie'. Anyway, folks seem to like the pedaling on it. It has torque sensing and seems to do pretty well, though you could turn the system off and it will still function as a bike a lot better than most ebikes.

BBS02 750W unexpected shutdown.
1.5 year old almost 5000km
Bike set up for city/road trip form home to work.
Chain ring 52T, triangle battery pack 52V 17.5ah.

Yesterday coming back from work I had a first sudden shutdown. I unplugged the battery, wait few sec. Plugged again and it worked again. But from now on which I'm drawing/using to much power I have a shutdown. Doesn't seem to be heat, I've a sensor temp never exceeded 130°F.

I wonder if it's more a controller issue or a battery issue ?
I've the same components since I started using the kit.

Thanks for your input.

E.

[paxtana]

If the battery BMS is not having to be reset like from plugging into the charger then it is probably more likely to be on the controller side rather than the battery. This is assuming that you are not hitting low voltage cutoff from sag and that time you are waiting is allowing the resting voltage to climb back up above LVC. If that is the case it would probably indicate physical damage on the battery itself. But it's a lot easier to replace a controller than open the battery and test cell banks so I would start with the controller.

[RiderRalph]

Hello, I am having a couple issues with my ebike that I am hoping for some help with. My setup is just under 1 year old - all ebike parts from Luna: BBSHD and 52V Wolf V1 battery. Here are the issues:

1) fan on 52v 300W smart charger seems to be no longer working to charge my Luna Wolf 52V battery. My recollection is that the fan alway ran when the charger was plugged in to wall outlet and connected to battery for charging. Seems to have changed to intermittent run in last couple days (for example, I could disconnect from wall outlet and battery, change voltage knob and/or current knob), reconnect to wall outlet and battery and then fan would run. Today, seems fan will not run at all. I opened the charger and ensured the fan power adapter is fully secured to circuit board (it did not seem loose or anything). Can you confirm that fan should always run? Also, any suggestions on why it is not running and how to fix?

Today, I ordered the Luna 52V mini charger to have as a backup and more portable charger. I will use this to confirm that problem is charger specific.

2) Separately, within couple weeks, PAS is no longer working. Like the fan, this seemed to intermittently stop working and now has completely stopped working. BBSHD works just fine with throttle so problem is isolated to pedal assist. I have tried to search for some info on this but did not find too much. I read that sometimes the clutch fails but this would seem to only occur for total failure of motor (i.e., failure of PAS and throttle). The only other thought is to check the wire (gray wire?) inside the BBSHD controller. Any input on this?

All help and comments appreciated.

[paxtana]

If it is actually charging then yes the fan should be running. I would check that the charger is actually running first.

Sounds like you might need to either reseat the PAS connector or replace the PAS board. Pull the controller, unplug the connector and plug it back in. If that does not work try replacing the board. If that also does not work it's the controller.

[RiderRalph]

Thx Paxtana. Yes, the charger is definitely running and appears to be charging as normal (though I do not let it run for more than a few minutes out of fear of it overheating w/o the fan running).

Re PAS, I will try to reseat the PAS connector. If that does not work, I will order and replace the PAS board.
