Re: Big spark from the charge port

Mine is a hailong battery too. I didn't see any fuses, are they hiding under the BMS? I still have 54v on the charge port and discharge contacts, so I suspect there is no fuse blown if there is one.

I've got 3-4 trips to work and this thing becomes a paperweight.

Big spark from the charge port

I decided to pull my battery off my bike last night because it was going to be getting cold and my bike lives in an unheated garage. It is also a fairly dimly lit garage. I couldn't really see what I was doing and I stuck the key in the charge port resulting in a large spark. I burned the - contact ...

Re: It's dead Jim. Dead battery pack

Hooked up the charger to the discharge port and it's now alive. 53.6V. I had 4 lights on the battery indicator so I installed the battery in the bike and the bike wouldn't turn on and 4 lights on battery were now out. I got a flash of light from the direct connected headlight (has a switch but not o...

It's dead Jim. Dead battery pack

Magnum bike with a 48V, 13AH battery. Woman left her house with a full charge, rode 3km, had coffee, hopped on her bike and it was dead. I put a meter on it and it shows 0.6V. I now sits on my bench. I checked fuses on both ends both good. Dead cell or BMS?

Re: 2 Speed Xiongda hubmotor

I bought a 36 Volt Xiongda 2 speed motor about 5 years ago. I rode it back & forth to work for 2 years then stripped a gear inside. About then I bought a Bafang mid drive. I repaired the Xiongda and put it on a bike for my daughter and she rode it for 3 years. Meanwhile I'd purchased a 48V 2 spe...

Re: I have a battery pack from a BH Atom X.

Yup, 18650 cells. I hadn't considered the additional cell monitoring. The pack is not like any other pack I've seen, I haven't ripped it apart so I don't know how it is physically connected. The cells are arranged end to end in 5 rows of 5 and 5 rows of 6. If it's as easy as ripping off one cell in ...

Re: PWD's Rocky Mountain Element - refresh

Nice choice for a donor bike, my daily driver is a 2004 Rocky Mt Slayer (Element's big brother) with the same linkage. The box looks tight to the linkage at the end of the shock, have you compressed your suspension to ensure the linkage doesn't hit the box?

I have a battery pack from a BH Atom X.

I have a battery pack from a BH Atom X. The electronics failed so I ripped into it. It's a 55 x 16500-35E cell pack with a charge of 44.5V (39.6V, 700WAh) 11x5. Kinda like 36V pack that goes to 11. The pack, if I decide not to rip it apart and make a 48V pack, will drive a 36V Bafang hub motor. I su...

Re: speed traps

What I wonder is how they can enforce bike speeding tickets if bikes are not legally required to have speedometers. Riding a bike on the streets of Calgary would be just asking to die.

Re: Using a hub motor as a mid drive?

I realize a 600 speed would quadruplicate many ratios. I'll probably go 3 at the cranks, 2 speed hub motor in the middle ( because I have one waiting to be used) and 8 on the rear (because I have a nice sram xo 8 sp shifter). Im going to fabricate the entire bike so im doing mostly fo fun. I electri...

Re: Using a hub motor as a mid drive?

I thought about that but then it's on the wrong side, if I want any gearing on the rear hub that option is out. That, and the motor I have doesn't have a disc mount.

Using a hub motor as a mid drive?

I'm in the conceptual design phase of building a recumbent bike. Typically these thing have chain lines that are 5-6' long so usually need an idler pulley. So I got thinking, why not 2 chains? Why not make the idler a hub motor? Why not make it a 2 speed hub motor? Why not put a mid derailleur on th...

My thoughts on the xiongda 2sp motor. I bought a 36v one direct from Xiongda, Bonnie was great to deal with. I got all the options because why not, they're dirt cheap. I sent Bonnie my rim dimensions and she added 251mm spokes for $8, how can you pass up pricing like that. I think they're 12ga so pr...

Re: Xiongda YTW-06 mini hub motor

Has anyone measured the output wattage at 48v with the stock controller? What is the top speed at 48v with what side wheel? Do they program the controller for max speed based on wheel size? I'm wondering if telling them I'm putting it on a 16" rim then building a 26" would it go faster?

How often do hydraulic brakes fail and leak? To judge by how often they need to be bled to have air removed from the lines, lots. And of course, whenever they're crashed and the hoses get yanked.
