If I store my trike (battery) for 4 or 5 months, is it best to completely drain the battery? 52v Panasonic 13.5ah Shark Pack and a
TRIANGLE 52v Panasonic GA 18650 24ah Pack HIGH POWER + LONG RANGE

[Tommycat]

Yikes... absolutely NOT! See this Knowledge Base thread for storage recommendations and other important battery care information...

Spoiler alert!


30% to 50%, checking every so often on charge and replenishing as needed.

[ROK Ride]

Figured out the settings, thanks for the tip. Volts on display reads 69.2 or 100% charged when the 52V advanced charger reads 55.5. What's going on there?

[paxtana]

Use a multimeter to get the most accurate reading and compare to see which one is wrong

[ROK Ride]

Multimeter and charger both read about the same. I plugged in the battery after charging to 55.9V/80% (multimeter reads 55.8V) and display still reads 69.2V/100%

[paxtana]

Sounds like you need a new display

Hi there, so my bike is having issues, it won't start up and I'm currently troubleshooting with Luna through a trouble ticket; however, I'm going on a trip for about 6 weeks. The "90-day warranty" on parts will expire while I'm on my trip. And well I know it takes like a week or more for things to ship from Luna. So this has me worried, I could have something shipped to my house, but I won't be there to test it out to see if it solves the problem. Does anyone know if I'm gonna get abandon by Luna right after that 90 day period even though I already submitted a ticket and am trying to troubleshoot the problem with them (pretty worried as other companies might say I'm SOL or tell me good luck)? Also if you have an idea of what might be wrong, please let me know.

Also here is what I've tested out so far:
- Battery voltage on my wolf pack is putting out about 55.7 volts (pass)
- Charger output putting out 58.8v (pass)
- Bypassed the battery by using the charger (fail, display and motor did not turn on)
- Plugged programming cable in to bypass the display (fail, throttle did nothing)
- Main harness connectors 1 and 8 were measured (fail, no voltage)
- Opened up the controller, all phase connectors were in place (disconnected them and reconnected them, no luck)

- Tested the mosfets using the continuity test(don't know if I was doing it right, so here are all of my results):

Results for the black lead from the multimeter into the Anderson connectors and the red lead to phase connectors:
Ground to Blue phase = no beep
Ground to Yellow phase = no beep
Ground to Green phase = no beep

Positive to Blue Phase = no beep
Positive to Yellow phase = no beep
Positive to Green phase = no beep

because I didn't know if i was doing it correctly in terms of drain and source, here are my results when placing the red lead from the multimeter into the Anderson connectors and the black lead to the phase connectors (basically the opposite of above in terms of where I put the leads).
Ground to Blue phase = Beeped
Ground to Yellow phase = Beeped
Ground to Green phase = Beeped

Positive to Blue Phase = no beep
Positive to Yellow phase = no beep
Positive to Green phase = no beep

Thanks for any help!

[paxtana]

Probably needs new controller. No we are not going to say we won't help on something so new.

[Jyang3153]

Thank you Paxtana, that was a serious worry of mine since I'll be gone during the end of warranty time.

[Marvin]

I just bought a 3000 watt kit is there any way to hook up a display to the controller and how to and what kind I need.

[paxtana]

I would go with a Batt-Man. You could also use a cycle analyst if you wanted to. Either way it's the same thing, splice into discharge with an included shunt for power metrics, and it uses its own speedo sensor for speed display.

[Chuckolicious]

Hey there. I sent y'all an email last weeks about ordering an X with a few tweaks. Haven't heard back. Mind taking a look and letting me know? Would love to place the order if it works.

[paxtana]

I have no way of referencing your email but emails are usually answered within a business day. Check you sent to correct address and maybe send an email asking for a reply if needed. That said, if it's not on the listing then it is typically outside the scope of the services we can offer.

[JBoyd]

Is it possible to over tighten the lock ring on the BBSHD, creating friction or tension on bearings or something, causing the need for more effort to spin the motor? It feels like there is a lot of drag on the motor on my new install.

[JBoyd]

Yes, I have a BBSHD with about 2500 miles on it on a separate bike. It spins easier, without the dry scraping noise I am hearing in this new one.

[paxtana]

No harm in opening it up and inspecting it, maybe adding a bit of grease if it's really out of whack, but probably fine either way. Definitely not the lockrings though.

[JBoyd]

Cool. Thank you.

[Moku]

Aloha Everybody I am new to the forum, hope this is the appropriate place to post this.
I am riding a fat tire bike with a Luna KIt BBshd with a 28ah 52v triangle Luna battery.
up till now i have had minimal trouble i have about 1700 miles on the motor have changed the clutch (freewheel) once. during a ride a couple of days ago i started feeling a grinding type vibration in the bicycle. and both the throttle and pas quite working, with pedaling still felt vibration and drag (maybe) in motor put pas to zero drag/vibration goes away. neither throttle nor pas will engage. when i push the throttle i can hear a high pitched whine like something is trying to engage. i checked all the connections, opened the covers checked the freewheel, and all the phase wire connections everything is good. still no luck. oddly enough i have found if i roll the bicycle backwards 5 or ten feet the throttle and pas will reengage until i try to ride it forward. i am at a loss. could it be my nylon gear going bad?
thank you for any help.

[paxtana]

Could be the nylon gear or it could be the helical portion of the rotor snapped off. Only way to tell would be to do a teardown.

https://electricbike.com/forum/forum/knowledge-base/motors-and-kits/bbshd/36670-bbshd-teardown-maintenance-and-greasing

[Moku]

thank you for the reply.
what is the helical portion of the rotor? can it be replaced?

[paxtana]

Usually you need to replace the entire core if this snaps. Fairly rare but it happens from time to time.

[Moku]

ok ill tear it apart on my next day off and see whats what. if i do need a new core do you sell it at Luna or do i send in the whole motor?

[paxtana]

Yes, we sell cores. I don't know what you need though without knowing stuff like how old it is, what size it is etc, and we are currently sold out of 68mm BBSHD ver. B which is the most commonly used motor. But if you got a fatbike, or a version A, then yeah we have it. Here is version B. You can see standard size option is sold out and therefore autohidden. https://lunacycle.com/bbshd-motor-core-version-b/

[Chuckolicious]

Hey there. The email I sent was to sales@lunacycles.com, 9/20 at 8:20am EST. I also asked for a reply to whether or not my request was something y'all could do. It'd be great if you could have whomever is responsible for answering these emails to respond and let me know. Luna Cycle Case #165016

[HIGHVOLTAGE]

Looks like one of our agents got back to you about 4 days ago. Might wanna make sure none of our emails are getting filtered in spam. Unfortunately though we are not able to fulfil your request at this time. Sorry :(

[zstauber]

Will the new DireWolf work with the Luna Low and Fatty Wolf? The swooping top bar looks like it might make the main triangle too small. Will the DireWolf work with the All Terrain Ranger 500? Not in stock currently, I know, but wondering for the future.

[paxtana]

This battery is rather large and it seems unlikely that it will fit in anything except a hardtail mountain bike that has a regular frame rather the one altered to be partial step through design. Even on hardtails it will probably only fit size large. The only bike frame we are currently offering this with at the moment is banana.

[Bluesoc]

Do you still stamp "750W" on the bottom of BBSHDs? Thanks!

[HIGHVOLTAGE]

Bafang stamps them that way for legal reasons. It is never an indication of what the motor is actually programmed at though.

[Bluesoc]

Thanks so much for the response. Just to confirm, they're stamped "750W" correct?

[paxtana]

Yes, they are.

[Tom on 101]

We have a BBSHS from 2017, we would like to run at 72 volts, is that possible? We were wondering if we could use the computer display from the cyclone to do this?

[HIGHVOLTAGE]

There is only one way to do this and it's currently expensive and risky. I would not recommend getting into this unless you're okay with completely burning out your BBSHD accidentally from overvolting. Check out ElectronCycles if you're interested.

[Lakejumper]

The red wire on my left side ebrake (Bafang BBSHD) has broken on both of my bikes. The casing where it attached to the brake has pulled away exposing the broken wire. The brakes are less than one year old. Can I repair it or replace just one or do I have to buy a pair? Thanks!

[HIGHVOLTAGE]

Personally I'd just unplug them and cap the connectors off and run with default brakes. Those brakes are so junky anyways and they really clutter the wiring up. Almost all bicycle brakes have enough stopping power in the brakes alone to bring the motor to a hault.

[Tommycat]

Just to put a finer point on the wiring... If the Red wire is broken, it should make no difference. As it's not used to actuate the controller motor off circuit. But it is hot with +5vdc controller regulated power, so secure and insulate it ASAP.



If the brakes are not actuating the motor off function now, one of the other two wires must be bad also or some other issue.

[Lakejumper]

Thanks to both of you. I will tape it off and use some silicone to reseal the rubber boot where the wires go into the brake.

[Chuckolicious]

Hey there. Just checked in spam and All Mail. Nothing. Does not instill confidence. But thanks for your time.
