With a 52v battery and proper gearing the BBSO2 will do 30+ mph

We should remind users that running a 52t or any chainring larger than 46t requires sensible use of gearing and shifting into those speeds, more than a few have overheated the 02. Good to check one shifting out with a watt meter to see the load when lugging these mids.

I was planning on a build with a BBSHD and 52v triangle pack. Since Luna doesn't have any 52V packs available, I looked at the 60v version. Can the BBSHD survive a 60v pack?

[Poco Askew]

Thanks!
Glad I asked.

[paxtana]

We have 52v flat fish packs, Mini packs and GA shark was just added back. Shark might take a few days extra to ship.

[Poco Askew]

Thanks but I'm looking for a triange pack to put in a Hitch.

These guys are supposed to be reliable but I have no personal experience with them. http://em3ev.com/shop/?prod_cat_=ebike-battery-in-case This guy is in a back order situation also. I have dealt with him and gotten positive results http://westcoastelectrics.com/produc...cells-80a-bms/

I have bought a lot of parts from these guys and had nothing but good results, no batteries though. They have 52s in stock. http://www.ebikes.ca/shop/electric-b...16-lim-dt.html

I bought the 60v battery sold on luna cycle (https://lunacycle.com/batteries/pack...onic-pf-or-ga/) which is 16s7p so it should have a max voltage of around 67 volts but the battery stops charging when it hits 63 volts. Even when I leave it on the charger it refuses to go higher than 63.3 volts. Not sure if it is a problem with the battery or charger. I'm using the 60v 450w 5amp charger thats sold on luna cycle.

[HIGHVOLTAGE]

Did you double check the charger with a multi-meter to make sure the LCD display on it wasn't displaying the incorrect voltage ?

[kc97214@gmail.com]

new website looks nice. notice you are not carrying the inverter anymore. do you plan to? can you recommend one that works with luna batteries? i don't remember the brand you had.

i'd like to be able to use the battery while camping, etc.

thank you.

I am sure we are but I do not have an ETA as of yet for this product.

[null]

I'm just wondering what the diameter of the actual button on the on/off switch is so I can adjust my model to fit it appropriately.

[paxtana]

This should be about right.

I'm not having any luck getting a response through support, so I'll try here. My brand new Fusion 680 arrived yesterday and looks beautiful, I wish I could ride it!! Unfortunately, it doesn't work. The battery did it's 100% balance charge just fine, I set out to do my first ride and the display works fine, shows 58.4V, the speedometer works, but no signs of life from the motor. Nothing from the throttle, nothing from the pedal assist (tried each of the 9 levels). I tried cutting loose each zip tie to check for crimped wires, they all look fine. I unplugged each connector and checked the pins - they are all fine. What am I missing???

[paxtana]

Probably something simple like a connector partially unplugged.

https://electricbike.com/forum/forum/knowledge-base/motors-and-kits/bbshd/39217-troubleshooting-a-completely-dead-bbshd-or-bbs02

Unplug the brake sensors, gear sensors, speed sensor or any sensor that can cut the power to the motor. For everything else, unplug and replug each connector.

[Davide_sti]

hallo,
I apologize for the language.
I'm building a frame for an ebike.
I would like some information on the bafang ultra (g510).
1) How do I connect the gearsensor? is it available for ultra?
2) Can the brake sensor be connected to the ultra bagang?
are they equal to bbshd?
3) I attach a photo with cables that I do not know what they are.
can you help me understand?

Thanks so much!!

David

[paxtana]

The circled item on right is speedo. I don't know if gearsensor is available with a dedicated plug but at the very least you could wire it up to the ebrake plug on the harness. Yes the ebrakes included can be plugged in, yes they are the same as bbshd.

There are no brake sensors, and no gear sensor. Unplugging the speed sensor didn't have an effect. I have already unplugged and replugged each connector (that was in my original post).

[paxtana]

Look for an error code as described in the link. This sign (!) is also an error, meaning the circuit for ebrakes is cutting power. If no joy and you have ensured the pins are all straight, nothing pinched or damaged etc, then email support. Probably a good idea to include some pics of motor/controller/wiring.
If it's powering on that's a very good sign, might be something like a phase connector come unplugged between controller and motor, as this would not throw an error would would prevent it from going https://www.youtube.com/watch?v=W0Q33n-aI7U

Hi Everyone,

Looking to start a conversion of my medium size 2016 Salsa Bucksaw GX1 using a 120mm BBSHD from Luna.
Currently in the planning phase and focused on a few areas from what I have read and wanted to see if others can chime in.

1st is the PF41 adapter.
It seems I should order the following 2 items. The first being of 120mm in length.

https://lunacycle.com/pf41-bb-adapter-for-pressfit-bb-fat-bikes-100mm-120mm-73mm/

https://lunacycle.com/bbsxx-custom-luna-triangle-mounting-plate/

Has anyone had success using these adapters on a Salsa Bucksaw and if so is the 120mm correct length?
If this does work the triangle goes on which side?

Or should I go with the other adapter?

https://www.empoweredcycles.com/products/shimano-pf41-bb92-89-5-92mm-to-bsa-adaptor-for-bbshd

2nd - I saw a post on the Luna website someone that did a Salsa Bucksaw conversion and was trying to identify the battery he used that seems to fit rather nicely in the triangle. Here is the link.

http://share.rivet.works/display/t/Change-how-you-ride-with-LUNA-/lunacycle-Product/9ca1bb32-d8ad-11e7-ab60-22000a5192ba?utm_source=rivetworks&utm_medium=ugc-display

Also considering special mount under triangle for the typical Shark Pack if need be.

3rd - And finally -
From the same link above it seems to be using a 42T Luna Eclipse chain ring, I have one recommendation for a Lekkie Bling Ring but have asked about the size recommended for a decent alignment of the chain.

Any and all advice is appreciated!
Thanks.

[paxtana]

The locking PF adapter is not variably length, only the regular one can be cut to length if you need 120mm.
Either Lekkie or Eclipse will give good alignment as long as you've got a minimum of 42t. Any smaller and it won't wrap around the secondary housing so it's further outbound.

[jpstuckinnj]

Thanks for the advice and information Scoonie and paxtana!
I included 2 links from lunacycle for the adapter pieces.
This was the one I thought was the variable length that can be cut to size.

https://lunacycle.com/pf41-bb-adapte...mm-120mm-73mm/

And this was for the triangle piece that I thought would be used with the above link to lock it in or is it not used for that?

https://lunacycle.com/bbsxx-custom-l...ounting-plate/

I did see this build that used the other adapter link that I included. Maybe I should just use that

https://www.empoweredcycles.com/prod...ptor-for-bbshd

Here is the build on a XL Bucksaw. Which makes me think I would not be able to fit the same battery where he put it.

https://electricbike.com/forum/forum/builds/ebike-building-directions/28886-bbshd-on-a-salsa-bucksaw-yeehaw

[paxtana]

The locking adapter is for regular pf41 widths only, it is not cut to size. The one that's cut to size is smooth rather than with teeth. With PF41 on a fatbike shell you would want the smooth one or some other solution.

Hello!

I'm trying to figure out how big of an impact would handlebar heaters (2x15W) would have on my ebike range. I used to believe you could just calculate power consumption straight from Ah rating (Ah / A = h) but it seems like thats not the case. Instead capacity depends on how fast you discharge the battery (20h rate etc..). Is there a way to roughly evaluate the affect (need numbers :D...) rather than just saying it wont affect that much (motor would be 1000w and the heaters 30w combined).
I'm interested in understanding the theory in any case...

Regards

[akkeee]

Thank you for this! Very informative. Just how wrong can you go by calculating Ah / A = h ? Does it give any comparable information at all or does it give too much or little? Is there a formula that takes discharge rate and every other thing into consideration?

[paxtana]

You are welcome.
The answer to that question depends on the cell. I do not know what cells you are using or even who you bought the battery from so I cannot say.
Different cells have different specs. A cell with a higher C rate (discharge rate) will have the least capacity loss from pulling a lot of amps. The previous gold standard for ebikes was NCRB, these had significant loss but good capacity if discharged at low amperage. Nowadays the standard is GA because it strikes best balance between capacity and discharge. There are other cells like PF or 30Q that have higher discharge rates but lower actual capacity. And this is not even getting into whether the seller is selling genuine cells, unused cells, Grade A cells. We make sure to use the best and that's why we're so popular but a lot of other companies just want to make a quick buck or do not realize how much fake stuff enters the global supply chain.

Anyway you can get a good idea from many of the spec sheets depending on the cell. Often the manufacturer provides this info with graphs you can extrapolate the data from. Of course if you wanted to get data specifically for your battery's performance that is also possible by setting up a testing station using a homebuilt discharge tester and our Batt-man.

It is important to keep in mind that the biggest cause of this loss is due to heat. Energy is never destroyed per the first law of thermodynamics. So that capacity loss goes somewhere, it escapes as heat. The higher the current the more the heat, so the less the current the less the capacity losses. Meaning that if the cell is designed for a high discharge rate where it stays cool there are less capacity losses. Same thing if you have enough parallel strings to spread out the load enough so that it drops the per-cell discharge rate to within more reasonable levels.

[akkeee]

So Ah / A = h would give some sort of idea of the run time or is it completely wrong?

[erbfarm]

My display won't turn on! Went to pedal home from work yesterday and no power from fully charged battery to display, throttle or anything. I've only had my BBS02 conversion kit for two months and it has been working fine until last night. We had some rain this week, but my bike was in it maybe for 40 minutes total. Didn't go through puddles or standing water. My bike is totally dead. Please help!

[paxtana]

You want to follow the path of the electricity to determine where the issue is. It starts at the battery, so first step is to test the battery, whether that is discharge testing using incandescent lightbulb, testing output with a multimeter etc. You'll also want to check the discharge terminals, both on battery side and controller and can even test for resistance between the connector on either side of wire, as well as checking for voltage same way.

If battery checks out you check the controller, the plugs on the connectors, try bypassing display if you have a program cable and so on.

All of this is covered in the knowledge base. Please see the links below. I would recommend reading both pages in their entirety before proceeding with the step by step instructions so you have an idea of the basics. There are several youtube videos included throughout the page(s).

[erbfarm]

UPDATE: The e-bike store did some diagnostics and determined the problem is within the battery. They will poke around more to determine if there is a loose wire etc. Will Luna replace this battery for me? I've only had it for two months.

[HIGHVOLTAGE]

We would need you to verify which part of the battery is having problems IE: bad BMS or bad cells. We have a BMS checking video for this:

https://www.youtube.com/watch?v=3Jkm0tfihe0

[paxtana]

22 is not a valid error code. It exists solely for prebuilt bikes using bafang equipment that has direct communication from BMS to controller. No such communication exists on bafang bbsxx kits.
