Settings :

Double press the "i" to access the settings. Once in the menu you will see display and information,

Information tab:

To see stored error codes and battery information (NOT USED)

Display tab:

You will get this, move up and down using the "+" & "-" and select with the "i", then when highlighted change it with the "+"or "-", confirm your selection with the "i" button again.

WARNING:

If you are using this LCD with a 52V battery the fuel gauge and the % level will not be accurate at all, they will both show full till you have 30-40% left. This can play trick with you, can make you think you are charged when you are not or can make you think the battery is defective. Even on a 48V system the fuel gauge is not the most accurate.

So we recommend you set the display to SOC voltage and not percentage. Check our voltage charts here if you are unfamiliar with voltage levels: CLICK HERE

---

NOTES and RECOMMENDATIONS:

• Even though it's IP65 rated, we do not recommend using a garden hose or pressure washer directly on the LCD.
• The display is not waterproof if a USB wire is plugged in.
• It's only capable of suppling 500ma (or 0.5a) so do not use it to power anything that requires more. No warranty on the USB port if used incorrectly.
• Do not trust the Password lock down, I could actually use the throttle while it's locked.
• The range function and any other battery info related functions will require a special BMS that is not available.
• Use the voltage mode instead of the %, it will be more accurate, you can use our charts here to guide you :CLICK HERE

OFFICAL BAFANG MANUAL (edited for BBSHD/02)

[Scott S]

Is anyone using this display yet? Looks pretty good to me

[Sebz]

It is nice, and many are using it now... but it just came out a few weeks ago. I'm using it for sure!

User Manual

[Sebz]

Thx Max-volt! I uploaded it on the top and edited it for the BSBHD/02 motors.

[Scott S]

Just to be aware that the manual shows a default listing on the settings page where you can supposedly select eco or sport modes but this is not correct. That spot is now for selecting how many pas levels you want to be able to select via the display and display controller.
A updated manual would be nice!

[max_volt]

Sebz kindly added red strikeouts. I wonder if eco/sport is for the new torque sensing models.

[Scott S]

Ya. If bafang can make a torque sensor for the ultra max why not the bbshd and bbs02 lol

[rwgreen89]

Have you ever thought about putting an Ultra motor on an EZ1 Super cruiser or other two wheeled recumbent cycle?

[Alaska_av8r]

Has this issue been taken care of "

• The range fonction and any other battery info related fonctions will require a special BMS that is not available.

From reading the above it appears that should not trust range function or "battery related" functions, also not trust the battery % function.

So in essence I can use the display to show speed and battery volts and thats it?

Also is the speed accurate when I put 26" in for the wheel size, I keep finding conflicting information?

[captaingeek@gmail.com]

Hi, when I plug the unit in, all im seeing is "waiting to load app...". Please advise.

[Thane]

Did you get an answer to this? Mine is doing the same thing

[MPieczko]

Does this unit or the other Luna displays have the different 'modes' that the 961 has? Specifically looking to see if it has 'walk' mode?

[ummagawd]

Sooooo my dpc-18/bbshd does NOT show "MAX PAS".... instead... it appears to be the "older" sport/eco mode options. Is this a hardware or firmware thing?

I have the programming cable and have written the "limitless" profile. But I seem to only be stuck in 5 PAS levels.

Can anyone help me get 9?

How does the PAS get allocated if it's programmed for 9, but the dpc-18 limits to 5. Is 5 considered "9" in this scenario?

[Rodney64]

It will be hardware, not cable will fix this, where did you get this display.

[MPieczko]

Does the DPC-18 have removable cable between the display and the button control? I'd like to do a stealth install and put the display in a bag under the seat with the battery, but then remote route the button cable to the bars. Just not sure if an extension is able to be used or the wires need spliced. The DPC-14 supposedly has a removeable calbe, just not sure the Luna 750c does or not, or the DPC-18.

I'd consider the stock 961 display if I knew I could extend the button control cable successfully.

[HIGHVOLTAGE]

Nope, unfortunately it does not. The 750c is also the same way.

[CC Rider]

I'm going stealth mode also. If all your using is PAS 1, do you even need a display?

[Sebz]

nope no need for a display. just use a program wire or a custom loop key to short out PL and P- and program your motor so that in PAS 1 you have the power setting you want and be done with it!

The same with me - cannot find a way to get 9 PAS levels, it shows sport/eco mode instead.

• Do not trust the Password lock down, I could actually use the throttle while it's locked.

Is there going to be a update to correct this? OR, Will we have to buy another dash to correct this programing SNAFU.

• The range function and any other battery info related fonctions will require a special BMS that is not available

When will this feature/BMS be available? ... I have the750c and it wasn't available for this ether.
Actually....Why even bother programming this in, its useless.

• It's only capable of supplying 500ma (or 0.5a) so do not use it to power anything that requires more. No warranty on the USB port if used incorrectly.

If the USB circuit is NOT part of the main PCB, then make available by stocking it, or us direct ordering the USB part.
If the USB is part of the main PCB, then this is product is completely FU in design and should be redesigned into 2 internal components, the USB more robust than it is.
My Samsung S8 Active will try to pull as much as 2A if possible, what good is a 500ma outlet? It won't even keep up the charge with the screen ON and the GPS working...LOL
Good 3 years ago, not now, not with today's phones! Has the development and programing upkeep of this item taken such a back seat...like back of the bus?!

I'm gunna dig out the DPC-14 and use that.....It works....(Sooo disappointed here).

[HIGHVOLTAGE]

Bafang is the original manufacture of these displays. http://www.bafang-e.com/ LunaCycle does not really play a role in ensuring these all of these features are usable and functional. Bafang simply offers them as an option if you wish to integrate it into part of your system

Sellers can take advantage of it if they choose but I don't believe we'll be focusing on that anytime soon due to the logistics involved with getting it work right. A lot of this stuff usually requires a bike that is pre-built and standardized under a single design. With kits, there are too many variables and differences in everyones build that it's a lot more difficult to design software that can cater to everyone's preferences. It is much easier to have basic statistics that are important like Voltage, Amps & Speed and to just use your phone to calculate other stuff like range or GPS if you need it.

[MichaelT]

Unfortunately that .5A USB scares the {content removed} out of me. Just plugging in my phone could toast the whole dash.
I actually would be better if you did not offer this item to the customer due to the potential damage that can occur, from just a phone!
Maybe it's time to develop your own dash LUNA....

[Sebz]

I charge my iPhone with it and it's fine. it will charge at .5ah instead of 2a. It's more of a warning about what you plug into it... like plugging a powerful led to it.

We haven't seen much failures on any display at least not from plugging a quality phone into it.

I'm pretty sure that bafang will never sell the USB part of it (if it's on a separate PCB).

Same problem here ... Anyone know of work around ?

[Sebz]

Hi are they from LunaCycle? Normally they should not show ECO and Sport. If it's from us email: support@lunacycle.com

[MoneyPit]

I hjave mine hooked up to a separate display that I know is accurate - a dual-motor setup where I have the same battery hooked up to both motors' displays, plus I've got meters etc. The DPC-18 is consistently reading 1v higher than the actual level. Sometimes under load, when the voltage is sagging, the differential is along the lines of 0.7v... but its always reading high. Anyone else seen this?

I don't suppose there's an adjustment hiding somewhere? Not expecting to find one exists but it'd be nice.

[HIGHVOLTAGE]

Normal behaviour for all of the displays including the DPC-18. There is no documentation or testing done yet on how to adjust it, or if it's even possible as far as I know.

[MoneyPit]

OK not a surprise. good to know mine is not defective in some way. thx!

[jth01]

I just setup the display on my bike and it was reading 0.7-1.0V higher voltage as well. Has anyone checked the accuracy of the power meter or current measurement for a 52V battery?

thanks.
