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 and hopefully restores contact to the display.

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 will be to use the good ? 6 cells to hopefully create a 24V battery. The bike is meant to have a 24V battery rather than the 36V battery. Do you know if the 36V battery BMS which has a 10S lead will still work with only 6 leads active ?. If this doesn't work then like you say it sounds like a new battery is in order.

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. After leaving bike for about 3hours battery then shows 37.9V (without charging) but immediately drops to 0.2V when tested again. Any thoughts would be welcome.

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 at that point. Can you suggest any other test ?.

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

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 a Powacycle Salisbury in VGC with a 180W rear motor. It probably should be powered by a 24V battery. My problem is that after riding the bike for about 10minutes the power dies even though the battery shows plenty of charge. Would it be the BMS on the bike that doesn't like the 36V or a problem with the BMS on the battery. If I remove (temporary) the battery BMS should it still power the bike. Sorry for all the questions - I am new to electric bikes and wanted to try one before buying a more decent one.
