    Speedict neptune lite

    Hello Speedict, Comparing the schema from the manual to the picture above: I have a question: In the schema Charging and Motor-Controller Wires are connected where they enter the Neptune. On the photo this is not the case. I assume they are connected on the inside, and there is no logical...

    Ultimate BBSHD Grin Phase Runner FOC 3000W

    Hey, this is a nice idea! I have a 20S Battery pack on my bike with a hub motor and wanted to use the BBSHD on another bike with the same battery pack. This sounds like a nice alternative to splitting the battery! Can you share some info on which controller you are using and how you connected...

    48V , 5A LiFeP04 Charger Repair?

    Hi Monstarr, I am not sure it would help if I published the values of my charger, because they all seem to be SLIGHTLY different. I have used Google Picture Search on "Kingpan, Kingpin, PingBattery, etc...." and found many pictures that had a similar layout (final Voltage adjust in the bottom...

    Did you see my post earlier in this thread: https://endless-sphere.com/forums/viewtopic.php?p=1160937#p1160937 I am not affiliated with this project in any way (Because someone already asked me if I sold that welder ;-) ) Cheers, Ulli

    18650 spot welding -how to- ULTIMATE REPOSITORY

    CHEAP NEW ORIGINAL 18650 21700 BATTERY CELLS, POUCHES AND PACKS

    > Well almost everywhere you see 18650 cells or Lipo or Lifepo4 you will see some reference to C value. Yes, of course I have seen those horrible "C" numbers and I do know what they mean. And everytime I wished, they would fire the marketing people that came up with this confusing term. The...

    CHEAP NEW ORIGINAL 18650 21700 BATTERY CELLS, POUCHES AND PACKS

    Guys, please don't invent new and confusing terms for existing terms: "DISCHARGE" is a very misleading term for what is really "Current" (measured in Ampere)! > Voltage does not matter, its the discharge you need to pay close attention to, > Simple example using 3.3V nominal, 3.5Ah and 10Amax...

    CHEAP NEW ORIGINAL 18650 21700 BATTERY CELLS, POUCHES AND PACKS

    > wouldnt it go from 12 volts, to 24, then 36 ...etc? I was trying to stress the point that each battery only "LIFTS" the water by "12V". Of course the potential of the water is getting higher and higher (24,36...) But the individual battery doesn't care. You can also think of it like a series...

    CHEAP NEW ORIGINAL 18650 21700 BATTERY CELLS, POUCHES AND PACKS

    > wouldnt each cell in series add its voltage to the next so that the final cell would experience the high voltage? I looked for one of these "Water Analogy" pictures to illustrate, but couldn't find anything suitable. So I modified one I found on the web. New additions on the left of the...

    > the cells wouldnt work correctly for high voltage like 74 Volts I am sorry you have to listen to a "Guy" that tells you that kind of non-sense ;-) Better not to listen to him any more, because the statement in itself is ridiculous: The individual cell in the chain knows nothing about the...

    Should we consider this to be an "honorary eBike"? The starter motor is bigger than what most people here use as their main engine ! ;-) Stumbled across this monstrosity in the WWW today... More info: http://www.lazareth.fr/project/lm-847-lazareth-v8-4700cc/ Note: I distance myself from...

    I was very sad to read that Jakov can't offer his welders any more at the moment. Hope he gets well again soon! I was lucky enough to still get one - but others are looking for alternatives. Until he is offering his welder again, this might be interesting: Today this popped up in my...

    Neematic - 20kW middrive bike

    I saw a couple of people asking if they will offer a Frame + Motor Kit, and the answer from Neematic was, that they currently only plan to sell it as a complete bike :-( Maybe we need to show them more interest from the community for a modular approach like the LMX. Cheers, Ulli

    18650 spot welding -how to- ULTIMATE REPOSITORY

    > But thats not rated for the 12 amps the parallel cells will use. Maybe I am missing sth, but I would have thought the the nickel-strips only have to carry half the Amps of the cells if you connect them at every point with the next strip. Lets make an example: My GA cells are rated for max...

    Hello Speedict! I would also be interested in a 24S Model #4 My pack has 20S and I believeyou will cover 99% of the market with a 24S model - there are very few users with 32S, and they will usually buy a complete BMS for Charge/Discharge etc. The users that are interested in Mobile-Phone...

    > on what length of conductor are they based? I would think that the length should not really matter: If you push a certain Current (Ampere) through a wire it reaches the same temperature at every point, no matter how long or short. e.g. check out this video...

    Wow! Great write-up! Thanks for letting us participate and learn from your findings! Just a thought for your new project: Wouldn't it be more efficient to use a direct-drive, placing the motor e.g. under the seat and with a long shaft directly into the water? Like the longtail boats in asia...
