I’ve only made a few enquiries so far and all have been negative even though I have tried to explain, as best I can, that charging my battery doesn’t use much electricity and I am not putting anyone in danger. Offering to pay generously for the privilege of doing so doesn’t seem to sway folks...

I think it's a cause for celebration. One of my ping batteries (36Volt 5ah)has reached the grand old age of 2 years. It's performing well beyond my expectations. It is used daily during the week and i reckon it's assisted either my wife's bike (or mine) well beyond 2000 miles probably nearer...

I'm going to order a BPM hub for my next build, but i'm having a spot of bother determining which code motor to order. I've just recieved an email from Michael at evassemble which states details of the hubs they stock and sell: EVassemble 36V BPM is code 10 48V BPM is code 13 Both european...

....someone is out to get you...... Hi everyone I thought you all might like to hear what happened to a work colleague of mine yesterday. He normally drives but because of the snow, he couldn't get his car out of the drive, so he decided to cycle. On leaving work at around 3.30pm he took a path...

Here is my new bike. A Marin Muirwoods 2009 model. I got this at a bargain price and luckily for me it was the last one they had. I like the look and design of these bikes and have been looking at these Urban bikes for a while. It has a lightweight mountain bike frame, skinny kevlar tyres...

Anyone useing a ping lifepo4? How are they performing? any problems? (pm me if you like) I have been thinking about getting one for sometime now hence the questions. Thanks

Can someone tell me, what is the max voltage of a 36V ping LiFePo4 pack after a full charge? I want to use a voltage regulator for my circuit (which will eventually be powered from a Ping battery pack). I have found plenty low cost devices, but the maximum input voltage is usually 40V. I know...

Following on from the discussion about Franks blown tongxin controllers i decided to make a current limiting device to have more control over battery consumption. I bought a 0-50A LCD display (complete with Shunt) from ebay as the base for the project. The voltage drop is 0-75mv for the...

Well it was good while it lasted:(. My battery pack is no more, it ceases to be, it's snuffed it. Here is the result. 30 D cells all totally knackered. It got so hot the solder melted and disconnected itself....Luckily! It's my fault for being such a cheapskate. I didn't have a suitable...

I'm thinking of adding a few more cells to my battery pack to increase the overall working voltage. I have tested mine between 30V-44V. 44V being the maximum i can get my pack charged and everything ran fine. I found the LVC was at 30V using a variable power supply, but was reluctant to find...

Hi Everyone. Well after a little delay, i now have my bike running with electric power. It isn't finished, as i intend to move things around a little or possibly transfer the whole setup to another bike. I merely wanted to build an ebike for my own interest, just to see what exactly is...

DIY battery pack questions I was going to use 3 SLA 12V 4.5Ah as i have a fairly short commute (price £44 the cheapest i can find). The bike i am in the process of converting is a mountain bike with a tongxin front motor. I figured i wouldn't be discharging the battery any more than 50%for my...

How do pedelec sensors work? are they basically on/off or do they have some sort of way of measuring pedal speed/effort.

Having spent some time looking through this forum, i would assume there is a higher percentage of people who have bought their electric bikes rather than convert an existing one (nothing wrong that i might add). But are people put off with problems sourcing parts to build there own? the...
