    Hailong 48Volt 17 AH ebike battery cuts out when power is applied

    Hi This screen is a laptop computer program? I think I can get all this from the display. I don't have the colour display but the basic one. I have to acquaint myself with it again and learn how to access all of this info. Now I know the output of the battery I will be better informed. Thanks...

    Hailong 48Volt 17 AH ebike battery cuts out when power is applied

    Yes bike works a lot better did about 6 miles then started to cut out again as you say need a charger to bring the low cells up. Still a lot better I guess there are dodgy cells amongst that group will have to learn to change them. Thanks a lot for your help. All the best Perry

    Thanks for the help this is amazing I have narrowed one cell bank to only 3.3V the rest are measuring between 3.7 to 3.8V. I have measured the charger and that only reads 49.6 Volts even though the output voltage on the charger is rated at 54.6V does it change with load or is there an...

    Hailong 48Volt 17 AH ebike battery cuts out when power is applied

    The battery is fully charged at 49.4V They are in banks of 10 5 The Voltage is 49.4Volts It looks if there is an imbalance as you say each battery is 2500 mAh 6 banks of 10 5 in parallel plus 5 in parallel so discharge max is 32.5A is that right? school boy physics.
