    Solar setup for internal LED panels

    Morning, I've been in and around electric bikes for around 5 years, built a few, learnt a load about batteries and what is needed etc. I'm by no means an expert, but can work out the right battery and controller size etc for a certain motor blah blah. Anyway, the house I've been renovating is...

    Building a light ebike with Q100 motor : advices ?

    Thanks guys :) As a reference, I would probably go for the 201 rpm motor If I had to start again or when this motor blows. I can only compare against a q128c at 201 but it did seem to climb a bit for effortlessly. A 201 at 52v should still do 22 - 24mph and that is plenty, doing 26 on this is...

    Building a light ebike with Q100 motor : advices ?

    I've just 'finished' my Q100h build using a Charge Plug 0 single speed bike and a 260rpm Q100H. I've done around 50 miles so far and its been great :) I went for a 52v 6aH battery that sits in a seat bag nicely and a 20amp PSW Power sine controller. Using PAS, I normally keep it on level 2 /...

    Q100H / 20A Sine Controller - Speed Sensor stopped working, display not registering MPH

    That's a good point! Its the motor phase wires that I touched. However, riding today the speedo seem to start working again but not right away. It took maybe 200 metres or so before it started registering the speed and no only works when pedalling but drops down to 0 when rolling / throttle...

    Q100H / 20A Sine Controller - Speed Sensor stopped working, display not registering MPH

    Hey, I've got a new project that is a q100h + PSW Power 20a sine controller. It's been working fine but this evening I've been tidying up the cabling a bit. Everything is back together but I've noticed the display (LCD3) isn't showing the MPH / speed no more. It's stuck at 0. I've tried a...

    Single Speed Charge Plug Commuter – Q100H | 52v 6aH Battery

    Slow progress on this sadly, weather over here has been horrid and I've been shortening every cable etc. I really wasn't happy with the way the Topeak bag sat and how the battery fit within it, I went on search for a more squared back and the LBS had some Giant seat bags... these literally fit...

    Extending battery cable with crimps, avoid?

    Thanks for the replies, I'm currently using these: https://www.diy.com/departments/b-q-blue-crimp-connector-pack-of-10/178108_BQ.prd Which I know wont be that great! I'm going to look at some higher quality crimps and see what I can do. I'm pulling hardly any power, <500w unless im using...

    Extending battery cable with crimps, avoid?

    Hi, I have a new 52v 6ah battery that will be used at 20a max. The power cables are slightly too short so I've used some of the same cable (12 awg) and connected it with basic B&Q / Home Depot crimps. I have been shortening all the other cables by solder, but these 12 awg wires are like thin...

    Do the Q128C and Q128H use same gears for 36V 328RPM builds?

    It’s not much help, but I ran a q128c at 20a for over 300 Miles and it never once got warm. I did mostly use PAS but was sometimes using the throttle and hitting 1000w to it.

    Single Speed Charge Plug Commuter – Q100H | 52v 6aH Battery

    This is my second electric project, the first being a lightweight road bike with a 48v 17.5aH battery and Q128C 210rpm rear hub. This was a fun bike to learn with but it was never quite the right combination. I've learnt that adding a massive battery and heavy (ish) rear wheel ruins the...

    Correct size pins and bullet connectors for 9 pin motor cable

    Hey, I need to shorten the motor cable but I can actually just repin the cables instead of soldering. Anyone know the correct size pins and the bullet connectors that come on the normal motor cables from BMS etc? Same as below:

    Q100H + 52v No load speed of only 19.3mph?

    Hey, I got my wheel back from yesterday from having a new Q100h fitted and last night got everything plugged together. It's a 260rpm motor, and I'm using a new 52v battery but my LCD3 display is showing that it tops out at 19mph under full throttle. Using the exact same controller and display...

    52v 6aH / Saddle bag battery for Q100H - Any changes for custom battery?

    Hey, same with me as he shifted me away from the 30q. After a longer discussion he said the VTC6's would suit what I wanted and I ordered it up. 52v 6aH (ish, he reckons the Sony's a bit over 3000) and the battery is actually smaller then the Luna Mighty Mini. The thing is Tiny! I'm waiting...

    Best solder for shortening cables? (PAS, Motor etc)

    Is there a potential for a soldering iron to be TOO hot for smaller wires? The main ones I wan't to shorten are the motor 9 pin cable and the PAS. These both contain thin wires. Also, any chance you could recommend a brand of solder on the amazon.co.uk site :lol:

    Best solder for shortening cables? (PAS, Motor etc)

    Thank you for all the responses! My plan is to cut out a section of the wire and solder back together, without touching the original connector. The power cables wont actually be cut, they are pretty short as it is. I'll see what non lead free solder I can find, Amazon doesn't seem to have...

    Best solder for shortening cables? (PAS, Motor etc)

    Hey, New motor is being delivered next week and on of the issues I had on my last build was the extra length of wire I didn't need. All of the cables; motor, PAS, display etc are going to be shortened to make for a nicer build. I'm new to soldering, but watching some videos I don't think...

    52v 6aH / Saddle bag battery for Q100H - Any changes for custom battery?

    Hi, I've posted about this before but wanted to separate into new thread. I've just ordered the bits for my new single speed Q100h build which is 260rpm 36v. My last project was a Q128C 36v and a 48v 17.5aH battery. My commute is 6 miles each way, the large 17.5aH didn't even go down a usage...

    DeWalt DCB546 - What cell capability (amp draw) could they provide

    Hey, I'm naive to battery tech but getting a custom Luna Mighty Mini clone built soon for around £300 from a UK builder. Whilst searching online I came across these: https://www.screwfix.com/p/dewalt-dcb546-xj-54v-6-0ah-li-ion-xr-flexvolt-battery/2832p. Which are 52v / 6aH (same as the mighty...

    UK plug charger for Luna Cycle Mighty Mini

    Hey, I'm close to buying the Mighty Mini but they don't stock a charger for the UK (220v 52v with a UK plug). I have no idea where to look for such a charger and what I should be looking out for price wise etc and also the right connections. Anyone able to point me in the right direction? No...

    Can anyone confirm if the Q100h is 32h and will fit 120mm drop outs

    Hey, working on a new project and it has 32h rims and would like to keep them this time (has to go 36h last time due to Q128c). This is a single speed project so want to go down the 'h' route with a freewheel. The Q100 says its 32h but the Q100H doesn't mention it. Also, will this suit a 120mm...

    Throttle on drop bar

    I searched for ages to find a good solution to this on my roadie project. My method was to take the standard thumb throttle and cut off the complete circle part. This left a flat surface and two small 'links' that I used a cable tie with to attach to the bars. I put the cable tie under the...

    Battery builder concerned over building a Luna Mighty Mini Clone

    I won't be ordering the MM but getting the Jimmy at Insat International to create a custom clone of it. I asked him to match the sizing as I feel like Luna have done their research on it. Its going to be 52v using the 30q cells so exactly the same.

    Battery builder concerned over building a Luna Mighty Mini Clone

    Hey great reply thanks. I never pull over 1000w with my setup even at max throttle and I am peddaling mostly so as mentioned im under 500w normally.

    Battery builder concerned over building a Luna Mighty Mini Clone

    Hey, I've just sold my large 17.5aH Shark 48v battery and have been looking to start a new lighter project. I'm going down the single speed route and re using my Q128C hub motor. I've been eyeing up the Luna Mighty Mini which is a 52v 6aH cube battery...

    Does a motor keep providing assist even when it exceeds its winding speed?

    Thanks for adding more to the reply. I'm using a q128c, the LCD3 display shows 0w when over 22mph. If I lift the bike off the floor and use the throttle the max speed still shows 22mph, the same as the top speed when just using the throttle on the road. I was just curious, 22mph is the winding...
