I got given a dead samsung laptop battery. There were 6cells, spec is 18650-22fu and joined in 3pairs and each pair at 3.3v. I charged the pairs with my bc168 to 4.2v and they held there a few days, so I discharged them at 1a down to 3.2v This took 6 hours which made me guess each cell is...

I have generally thought of the larger disc diameter means more braking force. With all this talk recently mentioning hydraulic disc brakes I had a wonder in our local halfords to see some. What I found interesting was one of the new models with hydraulics had a larger disc on the front than the...

Can anyone tell me if I can upgrade my controller for one which will work with my lcd display and capable of about 22amps? The one I have is a 14amp with shunt soldered up to 16amp and it gets warm now. In the future I will be using higher power batteries so may as well make use of the extra...

My ecycling related newyear resolution is going to be to NOT buy any more cycling gear all year, I mean nothing - zip - nowt - rien - nada - sodall. Trust me I will find it difficult as I have been eyeing up new parts recently. My reason is that over the past (1st) year ecycling to work I have...

I've been reading over the weekend about how the price of oil over the past year has dropped to multi year lows due to less demand etc. This is over the same past year I started ecycling to work, which got me thinking, crikey did I previously really spend that much on fuel, in fact so much I was...

Anyone know the difference between the Bafang C961 and C963 LCD displays which control the BBS01 ? I've asked BMSB but all they replied was one is cheaper than the other.

Just spotted this etrike vs Belt driven ebike on the Gadget show. http://www.channel5.com/shows/the-gadget-show/episodes/episode-9-342

I'm thinking to fitting some of these red 12v led strips down along the back of the bike frame. Is it possible to get a 12v supply direct out of my controller for it? Has anyone fitted them and found they are as easy as soldering wire to tabs on the end...

Picked up a couple of Schwalbe Marathon tyres and put them on the other day. I've only just noticed this on them. What could make tyres E-Bike ready I wonder?

Any lipo expert know is it possible to work out how many aH used of a battery from this info - 12s 8000mah lipo's started journey at 4.1v per cell and ended journey getting down to min volts of 3.73v per cell settling at 3.76v.

I would like to rig up an alternative to the hwbs sensors on my brakes. With my new found soldering skills what other methods are there I could have a go at.

If I change my battery permanent to 12s lipo 44v is there a way to change the battery level gauge on a BMSBattery LCD1 to reflect the new 44v nominal voltage? I looked at the advance settings but being Chinese to English translated I don't really understand them.

At about 4000 miles I've decided to check my chain for wear using the measuring trick with a 12" rule and find my chain is about 1/2 the rivet dia longer which according to the info I can find suggests it need replacing. I was hoping to get at least 5000 miles(1 year) out of it. My bike spec...

How do you insert a pic off your PC into a post? The 'image' button ask's me for a URL. I am sure there used to be a browse for pic function.

If a controller is modified to now give 20a, how many of those amps go through each phase wire? Should I be upgrading those bullet style crimp connectors after increasing the amps slightly?

My S06S controller tapers the power in when throttle is applied for a gentle speed up. Is there a setting to change the length of time the S06S controller takes to get up to full requested power, I mean shorten the power tapering-in effect ? Mine seems to take a bit long.

Ride of my life, Story of the bicycle. Came across this great program where the host travels the world for hand built bicycle parts to build a bike special to him. Also goes into the history of the bicycle too. Very interesting...

Whats the best way to find out an individual li-ion cell's capacity? I was given some old laptop batteries to try replacing the cells into my dead laptop battery. That project never worked even with all cells at 4.2v but I found some cells appeared to charge up to 4.2v ok using my lipo cell...

Completely off ebike topic but I believe there are some electronic 'old timer' geniuses on this forum who may be able to help my dad. He listens to 'wireless' (radio to us) on LW (or AM I think) and is getting a constant intermittent buzz buzz buzz sound regardless of where in the house I move...

I'm planning a future lipo battery of 44v possibly 8aH and am wondering if anyone experienced could tell me whether it is better to go with 2x 6s 8aH batteries in series or 4x 6s 4aH in parallel and series Both ideas are similar weights but I am thinking by using the 4x packs will put less...
