Morning all, A friend is looking for Q100CST motor for a 700c rim. Before he orders one from BMS, does anybody have one for sale in the UK? A suitable controller would also be great.

Hi Folks, Has anybody sound a source of Thun Torque Sensor BB's in Europe? I'm struggling to find one other than over at Grin Tech in Canada.

Hi Folks, I have a BBS02 for sale. I've covered maybe 500 miles with this one. I bought it new myself from BMS Battery. It was used on my roadbike for a short time. I reprogrammed it to 18A in the interest of longevity. I also used EM3EVs settings as these were much nicer as the initial...

Hi Folks, Does anybody recognize this hub motor? It belongs to a friend. He bought it with a box of e-bike bits. It is slightly unusual in that it looks like it splits into to halves rather than a centre with two covers. Any help appreciated.

A quick question about pack balancing. I have a 20s pack one of my bikes. When the bike is not in use I have an Anderson Powerpole loop disconnect. This results in two 10s packs. I only have a BC168 balance charger at the moment. Is it ok to balance charge half of a 10s pack, then the...

Hi Folks, This is a bit of an odd one. I've built up a new pack (7s x 2) for one of my bikes and one group of cells (EIG 20Ah) sit upon another in the frame. Photo attached. The balance leads for the lower pack are something like 400mm long. Is it ok to have a have a set of slightly...

Hi, Does anybody know of a supplier in the UK of the Bafang programming lead for the BBS02? I want to adjust my low voltage cut out as it is set a bit high at the moment.

Morning Folks, I have a 12 FET Infineon controller that is new out of the box. I hooked it up to a Crystalyte HS3540 at the weekend. There was an issue in that the motor would only run for a moment, then cut out. If I released the throttle I could do the same again. I am using 20s pack so...

Hi Folks, Does anybody have a lead on where I can purchase brake lever cut of switches (for hydraulic brakes), preferably in the UK? Cheers,

Hi Folks, I have built a 20s 20Ah pack for my latest bike. Hot off the charger this will be at around 83v (4.15v per cell). I have split the pack up into two 10s modules. When I leave the bike I will remove a plug that will separate them. My question is, how do I calculate the value of the...

Hi Folks, Does anybody know where I can buy a Cycle Analyst V3 in the UK? Cheers.

Hi folks, I've been balance charging my LiPos using a BC168 balance charger. It's working well but is a bit fiddly and time consuming. I want to use the bike to commute when I'm happy with it, so a simpler charger set-up would be great. Could I use on of these to bulk charge...

Morning folks, My power supply finally arrived for my BC168 balance charger. The question is, can I plug both of my 5.2Ahr Lipos in to the board supplied with the charger, so they charge at the same time? I charged them separately yesterday. Also, I'm charging to 4.15v at 4.5amps, does...

Hi Folks, This might be a slightly daft question, but is the power supply below suitable for something like a BC168 charger? I use it for electroplating as it can be very precisely set wrt surface area. Thanks for your help in advance, and once again, sorry if it's a dumb question.

I managed to take my bike out for it's first test ride this afternoon. I was using my reserve battery pack (5.2Ah) as the 10Ah cells are not in stock at Hobbyking at the moment. The battery pack wiring also needs sorting out. I'm running the two packs in series with low voltage alarms. First...

Hi Folks, Where is the best place to buy the BC168 charger? Ebay appears to have them. Any other ideas / advice as to where to purchase one safely. Cheers, Storapa/

Hi Folks, I bought two battery packs from Hobbyking. One was bulging somewhat when I received it. Hobbyking quickly replaced it. I decided to take the faulty pack apart as they didn't want it back. I was interested to know what was inside. Most of you probably know, but I thought I'd post...

Hi all, I've just received some cells from Hobbyking. Two identical 5.2Ah packs. One is rectangular, the other is bulging a fair bit. Is this normal? Also attached is a readout from each pack. The bulging pack is the one with the higher voltage. Cheers, Storapa

Morning All, I'm going to build a battery pack, similar to one built by Kinninvie., using a couple of Hobbyking Lipo packs. The 6s 10Ah and above packs are out of stock at the moment so I thought that I would build my reserve pack first (as the 6s 5.2Ah packs are in stock). The 5.2Ah pack...

Hi Folks, My BBS02 kit (48v 750W) turned up and is now fitted to my bike. It was a simple enough job. Tidying the wiring took the most time. I'll post up pics in the morning. Anyway....... It's time to start building the battery. I'm starting with some 26650 LiFePO4 cells that I was...
