Is it possible to reset a Wolf Pack 50 A BMS via bluetooth? Is there an app for this or will I need to download software for my computer?

[HIGHVOLTAGE]

No, this is not possible. The Wolf Pack doesn't use a bluetooth BMS. You can reset it the traditional way though:

https://lunacycle.com/jumping-your-luna-shark-battery-pack/

That is assuming that is the problem. What does the voltage of the pack read?

[johnt7303]

Hi, looks like my question got skipped. Did I post in the wrong place? From Luna website, says click here if I'm looking for a quick answer. I am. I'd like to get my Sur Ron back on the road for work and I'd just like to be sure I'm buying the correct master link for the 420 chain. Is there a particular width I need to buy?

[johnt7303]

Oh sorry. No problem. I'll keep checking back. Thanks

[johnt7303]

It's just a regular old 420 chain master link. No other special designations. Go on Amazon and buy any 420 master link

[HIGHVOLTAGE]

Ah good to know. Thank you

I have a fat bike with a 170mm rear dropout, would like an 1000watt to 2000 watt rear hub 48/52volt motor, do you now or will you have in future such a kit?

[Dakotarrb]

Do you have any idea when the BBSHD standard bracket size will be restocked? I was hoping to have it ordered so I can install and use it before school starts.

Thank you for your time.

[HIGHVOLTAGE]

1-2 weeks.

Hi, I'm super stoked about my first build - BBS02 with a 48v 17ah shark pack. Been on it for about 40 miles (after charging to 100% per the threads on battery care). The whole thing is cutting out at random. I notice the shutting down happens the most in 3 or 4 PAS and headed up a hill (even if I shift). I also noticed during one ride, jittery feelings from the motor. It also appears my ON/OFF switch on the battery is a dummy switch, as I can turn the screen on regardless of battery switch position and off i go, until it shuts off. Any Ideas?

[HIGHVOLTAGE]

Run it on a table and see if the disconnects still happen. If not, check the connectors on the underside of the pack like in this guide:

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

The switches are usually a failure point and a placebo effect, so they've been disconnected. The BMS handles all of that stuff already.

[madisonhamman]

Excellent. Thanks HIGHVOLTAGE. I'll run it tonight and my contacts on the crdle visually look pretty "wide" although its a brand new pack, i'll bend the tabs in a bit to add more normal force. Will follow up tomorrow.

Am I ok to run this battery down to about 20% thinking I can get one more day of testing on this charge.

[HIGHVOLTAGE]

Eh up to you, 20% is pretty low and will put a bit of strain on the cells but shouldn't be a huge deal for a new battery.

[madisonhamman]

Hi HIGH VOTLAGE, I tightened the dock contacts for more normal force. The issue remains. This morning, no bumps, PAS level 1, no hill, I got a shut off about 2 minutes into ride. Battery is still 75%. Turn back on, PAS 2, no bump, no hill - shut off. Turn back on, got to coffee shop a mile away, but had some jitter from motor.

[HIGHVOLTAGE]

It didn't shut off on the table? Yeah test it again on the table and make sure and then adjust the contacts again if it doesn't shut off. Are you adjusting them wider or shorter? They need to be closer together to make better contact with the cradle pins.

I have reason to believe your battery connectors are not making good contact with the cradle. We've seen it before. Even if they're brand new, or they look good. Just a few mm's off in adjustment and the voltage won't be able to jump over and make contact with the pin, causing a disconnect of the unit. The fact that it doesn't shut off on your table top indicates that this is probably the case.

Or you have a external loose connection somewhere else possibly. But you probably have already checked for this so I think it's the cradle.

EDIT: I've been getting other emails about this too for this same pack and one of the guys says he solved it by adjusting the contacts like I asked. So I'm pretty 100% confident this is the solution.

[madisonhamman]

Ok. Tested for a while longer on the bench. Can't get the shut off - I agree it must be some loose connection. I have a voltage reading of 46.6 V from my multimeter. I adjusted my cradle sockets on the battery side, as they looked completely wide open (in fact it was hard to get a screw drive behind them to bend them 'in' towards the pins on the cradle) - I will go even further with them i guess?

I did have a stupid moment tonight though - I didn't notice my red wire on my multimeter was plugged into the DC10A UNFUSED port the first time I went to test. Yup. I melted my probe, and partially the connector on the cradle. Can I order a new on of these? Once I swapped the red probe to the correct port on the multimeter, I got a solid 46.6v reading. Can I replace with these? https://lunacycle.com/batteries/conn...with-pigtails/

[HIGHVOLTAGE]

Replacing with XT90's would be the best for reliability. 46v is a pretty low battery by the way. That's like at nearly 20% capacity.

Hello, world. We have a Santana tandem circa 2003 - not unlike this image: http://www.mile43.com/cycling/images...a/santana1.jpg
Considering a BAFANG BBSHD Mid-Drive kit. Would it go on the front bottom bracket or the rear? Have these been installed in tandem's before?
We are around 350 lbs combined weight.

[HIGHVOLTAGE]

It would be the Rear

[prh88]

I love my recent purchase of BAFANG BBSHD MID DRIVE EBIKE KIT and the install went perfect.
When I roll the bike backwards, there is a clicking noise from the mid drive.
Is this normal? Any cause for concern?

[HIGHVOLTAGE]

Normal. Every BBSxx unit does it. It's the clutch.

Two part Sondors Thin question. I've already upgraded the screen, motor controller, battery (LT48), chargers, freewheel, chain, crankset and I'm current in process on brakes, tires, and bottom bracket (as mine is making some noise. All fine on those a parts...

1. Does anyone make a 52v battery that will fit in the thins box?
2. Does anyone make an upgraded motor replacement/better wheel options?

Thank you!

Chad

[HIGHVOLTAGE]

Sorry, we don't have much information on Sondors Thin upgrades right now. I think you can get a BBSHD to fit on the Original Sondors Fat Bike though, not sure about the Thin model. We don't have much experience with that unfortunately at the moment.

[stevenrt]

Will you be restocking the 48T sprockets for the Luna Eclipse BBSHD chainring? I have an Eclipse (42T) installed on my bike and am very happy with it, but I could really use a larger sprocket. Thanks.

[paxtana]

Yes we will be restocking it again.

[MIchaelB]

I have a Sunseeker at Tad recumbent trike that I would like to but a rear hub motor on. It has a 190mm rear axle. Do you have anything that would fit?

[m_hac]

Looks like these guys put a BBSHD on one!

https://www.electricspokes.com/products/sun-seeker-fat-tad-cxs-tadpole-recumbent-trike

[MIchaelB]

I am weighing my options between that and a hub motor.

[HIGHVOLTAGE]

No hub motors in 190mm unfortunately.

[geckocycles]

What spacing and hole count is the Rohloff Speedhub 500/14 Fatbike Hub you have listed for sale?
I need 190mm and a rim and spoke recommendation too.

[paxtana]

I think it's 36h, not sure on the rest

[geckocycles]

EDITED:Seriously buddy? We're not wheel builders here. Not the place to come here, complain and be rude. Be respectful. We're just trying to help with the best knowledge we have. -HIGHVOLTAGE

[prh88]

So I installed my mid-drive kit. Everything is great. Love it. Never did figure out what these parts were for. What are they for???

[paxtana]

Axle spacers and longer motor bolts. If you needed it you would know it

[Forcefed1]

when will I be able to order an Alite Plus again? or a lone wolf full suspension?
It seems all the battery options are sold out.

[paxtana]

Probably a few weeks.

[madisonhamman]

Adding a new comment here, as my previous thread has changed directions a bit.

I think my basic display is not showing accurate voltage. Shows full bars on display, and 3/4 LEDS on side of shark pack even though im getting a 46.6v read with multimeter. Is the display bad?

[HIGHVOLTAGE]

Did you adjust the connectors? It's definitely the case connectors considering it won't shut off on the table. That's like a dead give-away. It's like one of the most common issues with these packs. But you were also on low battery, so make sure it wasn't a combination of both?

[madisonhamman]

I did adjust the contacts, but they are still very wide open - im going to bring them in quite a bit and recharge the battery once I get the new connector in. Any option to get a better read on battery other than upgrading my screen? Would upgrading my display give me a good voltage reading?

[HIGHVOLTAGE]

Yes, upgrading to the color displays such as the DPC-18 or 750c will give you an accurate voltage reading at all times.
