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 ...

Greetings from Corsica.

Your petrol powered board is amazing....really fast. Great job...and a perfect lake with best conditions. Where is it?

Very beautiful.
Which MGM controller and jet drive are you using?

Check the black connector along the wire on the display that have problem with throttle, I had problems with throttle ad removed that connector at all.

Did you see this?

It was used on old Lampuga Boost and Air

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.

Sub'd

Me too

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 ...

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...

Looking to upgrade my bomber controller to be able to utilize the amps my 20s 30q pack can put out. The BMS can Put out 100 amp continuous 150 Max. Still want to use the CA. Mobius .. power velocity.. vesc ? I turned my ca back down to 60 amp from 65 because I was afraid my pants might catch fire. ...

It is strange that the capacitors burn, I think you will know that all the old Lampuga surfboards were equipped with MGM controllers

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.

Bei posti Rix per andare in moto

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...

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...

Thank you.
And what about this?
24S Nucular BMS for any kind controller - planned
When will the 24S BMS be available to buy with 24F controllers?

Any news about this?
Thermo Nucular Controller 24F - testing... (approx. 500~600$, ETA middle of 2019)

I keep blowing my lipos, will i reduce the time required to make the weld by increasing their voltage? And there by reducing the heat and stress on the thin aluminum terminals Im currently at 3s and can make a 5s batters from the cells I have left that are not broken (all the same 5ah 75c panther) ...

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

East coast rules.

Basically ride anywhere no one cares. Blank stares or ignored most of the time.

Hummm, here in West cost of Tuscany I would say also pedaling no more than 30 mph nobody care of you.
Is it ok at any speed for you?

I need a new seat and I want to try something like you have. Can you tell me where I can find it?

The temperature was pleasant around 12 °C

last Saturday with a friend of mine who has a mid drive e-bike I took the longest trip ever with the Bomber. 20190511_172604-2.jpg I did 35km off-road but the slopes of the hills near Pisa are 30km away from home so I covered 60km of transfers and I arrived 5km from home with the battery exhausted. ...
