Doubt it, but a left that curved out would suffice.

[AZguy]

You can find crank arms with different offsets but I think it's difficult to figure out how much offset they have online

[moarpower]

Luna and others sell BBSxx crank arms with extra offset. Putting a left side one on lined up my BBS02 bikes symmetry almost perfectly.

Seems they’re sold out: https://lunacycle.com/parts/bafang-p...left-or-right/

I usually use empoweredcycles when Luna is sold out: https://www.empoweredcycles.com/prod...ng-bbs02-bbshd

The above are the only stock BBSxx type crank arms with extra offset. I believe stock is 10mm and the above are 30mm.

I got moisture in my charging port of my shark battery and then plugged it in. Got sparks. Thought it had dried out and tried again and got sparks again. the end of the charging cord that plugs into the battery looks blackened. What now? Any articles, suggestions etc.?

[kerrylaw]

When I first got my new shark pack, I used to have charger not plugged into the wall, then plugged it into the battery. I ALWAYS got a spark. !! Now, I plug charger into AC first, then into charging port on the battery. Less or no spark now. Is this a possible situation you have?

[fos'l]

Thanks AZ & MP; ordered an offset left.

BBSHD Error list and Trouble Shooting as of 06-01-2016, 07:57 AM

=============================================

Error 04 Throttle no homing, Unplug the throttle, if the message clears up, it's time to replace it!


Error 05 Throttle abnormality: Throttle maybe damaged and not working, or the throttle may only work intermittently, Check throttle casing for damage, check wiring for a loose connection to the battery. Sometimes might happen with an installation where the motor is pinching the wiring exiting controller.


Error 06 Low voltage protection: Your pack is probably at 41V (48V pack) or at 44V (52V pack), if not try to program your controller to the right LVC


Error 07 Over voltage protection: Wrong battery pack installed use only 48V or 52V nominal


Error 08 Hall sensor: Sometimes corresponds with grinding noise: Check the motor plug to make sure it is connected properly, unplug and replug. May happen if the motor has been unplugged. Check that the plug pins are not bent. If not Needs to be sent in for repair. If you are a true DIYer you can open it and check if the hall sensor board is still fixed in place


Error 09 Phase line abnormality: Broken wire or circuit, Check wiring loom for breakages.


Error 10 Controller overheat: Temp sensor in the controller is triggered, let is cool a bit.*Possible phantom error*


Error 11 Temperature sensor in controller abnormality, same as Error 10, *Possible phantom error*


Error 12 Current sensor abnormality, Possible shunt blown in the controller, contact your supplier


Error 21 - Speed sensor error. Your speed sensor is disconnected or broken...check it or replace it. It may be that the sensor is not fully plugged in, not fully screwed into the plug, or that the magnet is too far from the sensor. Speedo sensors can be bought here.

Error 15H - Speed sensor error for the 750c display. Same as the above.


Error 30 - communications/controller error. Most likely a display problem, a wiring harness or the controller. If possible troubleshoot with another display (if you have access to one) .....

• check your wiring harness for damage or bent pins...
• check if you have extensions for the brake levers, throttle or gear sensor. Unplug everything before testing, then test by plugging each component individually in and power cycling the system.
• check that you are not pinching the wiring leaving the controller, or the installation is causing the wiring to be pulling out of the wiring exiting the controller.
• Unplug all plugs in the controller as shown here, then plug them back in.

My frame is almost ready and I am ready to pull the trigger on the bafang ultra max - ludicrous mode. Question - will the high power version of this battery work to support the 2500W config ? ? https://lunacycle.com/52v-panasonic-...ah-shark-pack/

If not, then which one will work ?

[moarpower]

Simple answer: Not unless you plan to ride slowly. Pick any battery that has a 50 A continuous BMS if you want to get the most from a Ludicrous motor.

Lazy answer: Skip the Ludicrous edition and use a regular Bafang which does not pull too many amps for the shark pack if that’s the battery you want.

Long, somewhat technical answer: That battery pack only puts out 30 Amps continuously. A stock Ludicrous pulls up to 50 A and could shorten the life of the battery, BMS, or cause it to cut out under high loads (ex: going up a steep hill). Bottom line is that the battery, even with the 13.5Ah GA cell option will be the weak link in the chain.

Ideally you want your battery’s continuous amp output to be the same or greater than the max draw of your controller. Since the Ludi pulls 50A, you want a battery with a 50A or greater continuous rated BMS. (I think all of Luna’s triange packs have 50A BMS.)

You can also use two packs wired in parallel. When you wire them in parallel you add their amp ratings. Two shark packs would be 30 + 30 = 60A continuous. I use two Mighty Minu 30Q packs in parallel for my Ludicrous BBSHD.

Please note all of the above is in reference to 48-52V batteries.

[AZguy]

If you use a 30A battery change the limit in the controller to 30A and have a very robust, cool running controller

There is a high power version of the battery pack - is that something that puts out 50A ? Appears like that to me - hence the question.
Yup - the triangle packs are good but I'm looking for a smaller pack.

[Ravewest]

Is there any idea when the Cyclone 3000 with a standard BB will be available again? I am anxious to place an order and get going on my build. Also looking to get a Bafang BBSHD 750 unit with the Luna Crank in an anodized black color. Again, looking to find availability estimates.

Thanks,
Don W.

[paxtana]

Hopefully within a few weeks given that spring is quickly approaching. We do have the cyclone mini if you don't want to wait. Makes for a pretty nice alternative in combination with our sinewave asi controller.

The special Luna cranks were a limited time offering for black friday, we don't have any more sorry.. whether we will do another production run or not is not something I know the answer to, I would say probably but there's no set timeframe. We do have the lekkie buzz bars if you want aftermarket, and several other alternatives are listed in our documentation https://lunacycle.com/lekkie-self-ex...set-buzz-bars/

Paks need a certain number of cells to give you the amps you need. Let us look at one of my favorites, Luna's 52 volt 24 amp/hr triangle. Luna lists it as "

14s7p = 98 Genuine name brand grade A 18650 cells"

If you know all this ignore me but it is a good thing to spell out because it took me a while to catch on and it may help some noob's. The 14s stands for 14 cells in series or 14 times 4.2 volts per cell = 58.8 . That is where your 100% charge voltage comes from.

Let me copy and paste some Kool Aide from Luna's store about these GA cells.

• GA Sanyo cells, guaranteed Authentic
• 3400 mAh huge internal capacity
• Ideal cell for most ebike builds
• 10 amp discharge...double the amperage of the NCRB 3400

So what does all of that mean? The pak is a 14s 7p. The 7p means 7 cells in parallel. Take your 10 amp discharge per cell times 7 and you have your 70 amp peak that this battery is rated for but the 50 amp continuous is a more realistic output.

What is a milliamp? It is 1/1000th of an amp or .001 amps. Take 3400 mAh times .001 times 7 and you get 23.8 Amp/Hours and that is where that figure comes from.

What this all boils down to if you want a 50 amp continuous pak that won't stress your cells you need a 7p. For 52 volts you need 14s. 14 times 7 is 98, and that is how many cells you need for your pak.

The cells that Luna is using in the Apex have some freaky specs and could change all of this. These batteries are expensive and hard to get so we will just have to wait until Luna starts making some paks with the new cells.

[Loppy]

Hey ya’ll Luna freaks. Having a bit of an annoying issue i was hoping someone might have insight on. Search on here and www was fruitless. This is my 7th or so bike build and have countless eSkateboard builds and even more SUAS/multirotor “drone” builds, so I’m not exactly new to the generically similar systems... anyhoo The build is the Cyclone 3000w + 60a Bluetooth and 3-position switch controller, 72v on a Rocky Mountain Flatline and it came out sweet after some considerable shop time... I got it fully dialed in mechanically first, ran the system for a bench race via stock glob of spaghetti harness with big fat ugly lame Chinese connectors and everything worked perfect including PAS. Then cut out a mile of unneeded wire, soldered up what I wanted and cut off rest. I decided to run the PAS plugs up to a switch in the 3-position controller and unfortunately when pushing it in I didn’t see something and shorted a few wires right by the switch. Fixed that. Now my PAS doesn’t work. I’ve swapped out the crank sensor, bypassed the switch, checked all the other connections that appears same as when it worked... nada. No PAS now. Fingers crossed big time something didn’t fry inside the controller... but everything else works perfect (OMG is this thing a blast...).

If anyone has any half way decent way to point me... I’d sure appreciate it. Many thanks! (Ordering 2 more kits for client builds).

[paxtana]

Maybe swap in a stock controller for comparison?

[flyerguymn]

What adapter do I need to use the Luna 48V charger with a 4-pin XLR battery (the 17.4A battery pack from Juiced Bikes - https://www.juicedbikes.com/products...battery-pack)? I saw a 3-pin adapter on the Luna site but not a 4-pin, yet I believe Juiced owners are successfully using this charger. Thanks!

[paxtana]

We don't support Juiced so I don't have info on the specific adapter or where you could buy it.

That said, easiest way to use an aftermarket charger with a rare or unique plug is to simply cut it off of the stock charger that came with the bike and attach it to the new charger. This can be done by soldering the wires, using solder sleeves and a lighter, using butt splices and a crimper, or even just some WAGO lever nuts.

*this is general advice and does not constitute a guarantee of compatibility. how well this works could potentially vary depending on bike/charger design, but odds are it would work fine as long as you get the polarity right and ask others for advice if you don't know how to do it

[Scoonie]

Find it on electricbikereview, several juiced thread and many users there.

Yup - the triangle packs are good but I'm looking for a smaller pack.

If you can find one a 14S 4P pack of 30Q cells will do 60 amps continuous. It would have to have a 50 amp BMS. 12 AH. Or just buy 2 mini cubes 30Q. Wire them parallel. That will be 60 amp continuous capable. I use the 2nd solution with my Ludicrous.

[jrothe]

I just installed a new controller and display (DPC-18) in my BBSHD and it ran fine until I changed the controller settings and possibly ran the battery down. Now, depending on which battery I'm using (one around 52V, the other 53-55V), the display will either not power up at all, or it will only work with no load on the motor (cuts out completely a few seconds after load is applied). My question is, is it possible that the controller will not power up at all or shut-down completely, due to an undervoltage condition from the battery? I have checked the error log in the new DPC-18 computer and there are no errors showing. I would also expect the display to some kind of warning before powering down and it is strange that it is not even powering on with a battery charged to ~52V (52 V Luna shark). With a different, fully-charged, pack the bike seems to run OK.

I've checked the controller settings and even set the low-voltage cut-off to the minimum and it doesn't seem to make any difference.

[paxtana]

It's more likely a fault in the power delivery from the battery to the motor. Which could be from the case to the cradle (most likely), or from the cradle to the controller.

Good place to start would be to check the contacts if using a shark. Please reference the shutdowns/contact maintenance section of the battery doc.

https://electricbike.com/forum/forum/knowledge-base/batteries-aa/12542-luna-hardcase-battery-documentation?p=35701#post35701

[jrothe]

Thanks paxtana, I will take a look into this tonight.

[jrothe]

Indeed, it turns out that the contacts in the battery were bent/fried. My previous controller failed to a dead short circuit so the high current vaporized half the contacts on the battery. Thank you for the advice.

Is there a way to order new contacts for the shark pack?

[fos'l]

Final assembly of the latest BBS02 conversion and the controller has bullet connectors for the battery. In the past I just lopped the bullets off and replaced with X(-90T since that's what my Luna batteries have. This time I would like to retain the bullets. Do you have or plan to offer bullet to XT-90 connector.

[HIGHVOLTAGE]

Not likely as bullet connectors are not great for maintaining a strong and secure connection.

[garyinco]

Not a tech question but didn't want to bother you with a phone call...
Any plans on selling the "Custom 52v Luna Fusion 24ah GA" by itself? I just bought an Alite Wolf and would love to have the range of this battery. It looks like it might fit in the Alite's triangle. Thanks. I'd be the first buyer :)

[HIGHVOLTAGE]

As of now, this is currently not planned but the Wolf Fusion pack will soon be available on it's own.

[garyinco]

Thanks, HV.

[Ebiking Cajun]

New 52V BBSHD, I seem to have just run into a problem. I got everything assembled last week. I charged the battery before using it. I took it out for ride, and what a blast! It has been far beyond my expectations. I’ve only ridden it a few minutes at a time over several days. Today I took it out for a ride and noticed the battery voltage had gotten down to about 48V, so I thought I should probably put it through another charge. So I hooked it up to the charger just as I did the first time and the charger just clicks off and on. Here’s an example of what it doing. Please advice! https://youtu.be/qeL0Ml4irZ0
