    N.E.S.E. the no solder module

    Hi. Yours is shipped via FedEx. Will email tracking. 👍 My kids have grown a bit and i decided to build enduro bike for myself as i have more time to spend. Decided to go with light battery, 20s8p. Will be using p42a. Expecting lots of pooooower, so i will be using my 2s4p module for 8p double...

    N.E.S.E. the no solder module

    Depends on the cell. 18650 module is 75x20.5x whatever module size, 21700 is 80x23.5x whatever module size and 26650 is 75x28.5x whatever module size.

    N.E.S.E. the no solder module

    I have a battery left outside in one of those children electric contaptions. After 2 years still works but i have not checked inside yet. I would advise enclosure for any battery.

    N.E.S.E. the no solder module

    All depends for how long and how offten. Should be alright up to 200A for 10S occasionally

    N.E.S.E. the no solder module

    Have a new little add-on to NESE system. Its a retention pin that locks modules between them selves. Its 3D printed plastic pin but still very strong. Only downside is that lids don't have access holes so modules need to be stacked bottom to lid and polarity markings render irrelevant. But...

    N.E.S.E. the no solder module

    Sorry, but i need you to put your questions clearer. So your battery space is 357x160x120mm? You have battery that is 72V and 26AH (20S) and you want to build a battery that is 72V and 36-40AH? You want to load that battery with 210A peak? If you can get that into your space, the my solution...

    You can contact me via email as you did with cad files you have for space and i could take a look and give you my 2ct

    Lambretta conversion

    There is no difference in capacity 18650 vs 21700. Its same lithium cell in a different package. If you would use NESE, then you look at what will package best in your given space and even then its very close. There are great cells in 18650 and 21700 are the most deviating from the standard...

    Lambretta conversion

    Your system voltage is your constraint how many modules you can fit. For 72V nominal it is 20 modules in series and you can do multiples of that, so 20 or 40 or 60 and so on. 40 will be 20s16p with 8p modules 60 modules will be 20S24p etc.

    Hi. Can someone reference to dimensions of battery compartment and top opening dimensions on beta frame? Thank you

    Battery connection method

    Could you link to that article? 400N does not say much. If its on area of the positive contact, that's 40kg per contact. Thanks

    Battery connection method

    Have you considered getting 3D printer instead of a spotwelder? You could get decent ender 3 printer for less than kWeld and use it not only for battery but around the house, on bike builds. Here is a photo of a bikes i did for kids, makita battery converter with integrated esc on red one: 12V...

    N.E.S.E. the no solder module

    You can grind cells down with dremel and use cells but at your own risk. As this is a friction method, contact are must be as smooth as possible and you cant achieve that with used cells. Its OK for low power applications but not e-bikes. High current pull with introduce arcing and contacts will...

    Electric quadmobile(looking for some help)

    Yes, those were the ones but it looks like they are not too good. Found this one, by the looks they are supplying LMX if i am not mistaken. Looking at these SL120-12-50SPM(https://www.senlimotors.com/e-bike-motor/sl120-12-60-bldc-motor-mid-driving-motor-for-e-mountain.html), 1.2kW(60V) motors...

    Electric quadmobile(looking for some help)

    Those MAC's i am looking at are 1kW rated power so i think you can get 2kW out of them easy for few mins which would bring them to 4kW peak

    Electric quadmobile(looking for some help)

    Looked at motor options and there is MAC M12500-3A inrunner, 1kw, 48v at 1.6kg (or maybe 2.5kg). In either case it would be a lot lighter than going with hub motors. QS 20" wheel motor is at 9kg, other hub motor they have are 16+kg so that is substantial. If i could figure out simple trailing...

    Electric quadmobile(looking for some help)

    The roads are pretty ok vut occasionaly i would like to go on small gravel roads camping, fishing etc. Those couple motors would be great but i think they are too small for me. I was looking 20" bmx size or 17" moped. How about building trailing arm suspension at the back and placing motors near...

    Electric quadmobile(looking for some help)

    So i build some bikes in the past and now as the family has grown to 5, need something bigger and enclosed to be able to use it all year round. I am planning using off the shelve quadracycle double a arm suspension parts for my suspension and i am brainstorming my propulsion options. Where i...
