Hi Flecc Just a short note of thanks for your Panasonic site. It cured to two problems on my second hand Raleigh Leeds tour. Rubber inner tube cured poor connection and reversing sprocket cured clunky engine noise. The sprocket is 9T will a 11T increase speed. I'm getting about 30miles per...

I have a Raleigh Leeds tour that had a faulty LCD display. I followed advice I found on this forum and fixed it. Cut a piece of old rubber tube to fit under the battery with small cuts to allow the "prongs" fixed to the bike to poke through. This gives a tighter hold when you insert the battery...

Once again many thanks for your replies. Much appreciated.

Thanks Nealth I have just read a post from 2013 (Thalmosy) and some of the suggestions there. I have tested each cell and find that 4 of the 10 cells show zero charge, I am currently seeing whether these individual 0 cells will take a charge using the BMAX charger. If they don't my next stage...

Connected the MultiMeter and found the following. At start 39.7V. Five minutes riding and intermittently the motor will stall but battery still shows about 36V. Stop for a minute and bike will continue for another 5 minutes. After 15minutes battery drops to 0.2V and bike will not continue...

Thanks for the info.

I'll need to reassemble the battery and then i'll try the multimeter.

The batteries weigh 2kg each so 4kg for the 40V. The batteries are out of an aluminum case that has a very faint label saying DC37.0V. Hope the above helps.

Thanks for the reply. The bike doesn't have a battery level indicator I have checked the voltage on a multi-meter and also using a IMAX B6 on each bank of 5 cells. I am going to rig the bike up to let it run down the battery to the point wher it cuts out and see whether there is any power left...

Thanks for the reply. I'll weigh the batteries and also try to get more info.

Hi I posted a question about a battery and wondered if I could ask that you might give it a quick look-over. Fingers crossed. Its listed under Gilbern.

Please can someone identify the battery cells. They are in 2 blocks of 5. One block gives 20v the other block gives 19.7. They are wired in series with connectors going to a 10S port. BMS ?. What is the maximum charge these cells can take and where in the UK can you buy them. The bike I have is...
