Re: E-S Stealth Electric Bike Owners

Nicely done Karl. If you can build these in 12 hours each I may as well give up now. You could be onto a winner if you were willing to sell them. Maybe I'm too meticulous, but my packs typically take 30-60 hours to make. Hence my pricing that many can't stomach. Cheers About 60 hours is the time I ...

Re: Storm Bee electric dirt bike

I love some of the stuff I read because sounds like DIY oriented.
It sounds like a 26S16P 96V battery made with 416 Sony VTC6 that at 22Kw deliver around 230A and 14A/cell.

Re: Electric Surf Board

yeah, those Esurf boards look very well made, next gen stuff. but they cost like 20'000 so for that money, you would expect the best! Yesss 20k + VAT .... around 24k€ but based on the video they posted at the end last year they seems to be the most powerful and reliable jet boards and I would love ...

Re: Electric Surf Board

yeah, well they must have figured out a way to stop them exploding. maybe they went with external watercooled caps banks also, I personally saw two of the old Lampuga surf boards opened and there was anything like that mgm were literally useless, they had no tech insight to offer, rarely replied to...

I have both the spot welders Allex suggested and have been spot welding with a 3S5P lipo battery I made some years ago with old cells from an e-scooter and I still be able to make battery packs for local buddies.

Re: Nucular electronics - complete kit for ev! [beta]

Hi Vasiliy I'm interested in your BMS 16s. Can I run 350 - 400a through this? Do you have any advice for doing so please? Cheers I have not seen any schematic yet but I assume that the BMS that will be supplied with these controllers will not have to take over the flow of the current but only to mo...

Re: Nucular Electronics owner's thread (setup infos, FW updates, links etc.)

To get the full (setup)speed with only a little throttle is expected in torque throttle mode, when you don´t have any load. Because you don´t control speed (voltage), you control torque (amps). Very little amps are needed to run at full speed without load. I am curios, are you one of the first to g...

All the cell level and pack level voltages are set very conservatively (ie low) at around 3v a cell,
You should explain some more what does it mean or post a picture of the BMS setup
