    Fix 2 problems with 1 project

    The better idea is not to start from there. 1 Sell the battery to someone who needs it and replace it with 12v battery this will be a better match to those outside lamps you were considering. 2 split up the battery pack into a 60 amp hr 12v arrangement All other arrangements waste more power...

    Reduce Charger Voltage

    If you are uncomfortable with the output voltage from this charger, you can reduce it by 0.7v very simply by inserting a power diode in series with the output. Cut the red output lead at a convenient place and solder a power diode from the 1N 4000 seriesor or 1N5000 series into the lead. The...

    Yamaha 500w battery 2017

    The only point I was making in selecting that instance is that one's freedom to engage in commerce is more circumscribed than your initial statement would suggest . There were a number of conclusions and ramafications from that case regarding civil liberties with which I would have issue.

    Hi d8veh The heart has reasons that the mind cannot follow, it's his time to waste not ours. Yours is the voice of rational reasoning he is following another path. Happy Christmas

    Maximum Speed Control

    I don't understand this response. In a number of previous threads you have referred to a DC brushed motor. Are you now stating that it was in fact a brush less motor, which in essence is an AC induction motor , and which needs a complex controller?. While these brushless motor controllers are...

    Electronics question unrelated to ebikes.

    Ok I have a peugneot 3008 diesel with the same type of battery protection, even 15 minutes of the radio on with the ignition off will cause it to go into eco mode and the radio will switch off until the motor is turned over again. This is to protect the motorist.. the primary purpose of the...

    Electronics question unrelated to ebikes.

    Hi unless we know the make and type of the stereo no one here can answer the question properly. D8veh analysis that it will take only 24watts will be true if it is one of the simple stereo radios , on the other hand if it were one of those really high-powered jobbies intended to wake the dead...

    YAMAHA EASY.. Old pedelec ebike but the 24v mid drive unit has potential

    ... Inadvertent posting.... 1.5watt or 15watts in total. That is best case. Using Li ion as the voltage per cell is 3.7, you are using 3 times less and the corresponding power loss reduced. Any soldering failure in a string removes cap acity by 10% , commercial units are cross connected and...

    YAMAHA EASY.. Old pedelec ebike but the 24v mid drive unit has potential

    Hi I do not want to rain on your parade, and in light of the response you had to previous suggestions, cautious about advising, but ..... If using your NIMH cells , They only have at most 1.5 V and many are at around 1.35v , so each string required to get up to 25v will need 15 or 16 in...

    YAMAHA EASY.. Old pedelec ebike but the 24v mid drive unit has potential

    The are nicad battery packs , probably used with pagers or mobile walkie talkies. .. think security guards. The peak voltage per cell is less than that of NIMH types and the power density less than 50%. Cadmium is a poisonous metal and needs to be disposed of correctly. NIMH and nicad have a...

    Whom here has said that cycling is not dangerous? Actually I have said so and provided the statistics to back it up. 113 dead as compared to 3 times that in drowning, walking, 6 times that in motorbiking and 9 times that in cars. Cycling is not a hazardous activity. There are occasions and...
