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

I have made very simple survey and if people who purchased parts or kits from me, could spend 1 minute of their time to fill it in i would appreciate it. I would appreciate unbiased, good or bad.

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

very cool agniusm. these are compatible with Lebowski controllers or just using a Arduino to aggregate the temps and cut off controllers if any go too hot. Thanks. You need to use some sort of microcontroller as you might have 100 probe point in your battery pack that needs to be addressed. That gi...

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

Some modules will be used on student formula e car. Rules require one temp sensor per max 3 cells. Here is 8P nese with 3 DS18B20 sensors. These could be linked, only 2 wires needed and each one has its own signature. Modules are over 3mm wider and now they could be stacked to one side only: https:/...

Re: Do I need diodes with this layout?

So, you have to do the math if that balancer will be able to keep up with your charger, otherwise you will overcharge. The BlocBalancers are by default set to 4.15V before tripping. I may even opt to order them custom programmed to 4.1V max -- need to think on that a bit. Another thing I plan on do...

Re: Do I need diodes with this layout?

How do those balancers work? I think you need bms as per your previous illustration. OK, i have read it. So, you have to do the math if that balancer will be able to keep up with your charger, otherwise you will overcharge. There is no need for large disipating resistor if you use new branded and go...

I have to congratulate you on your clever, well-thought-out design. I think your pricing is more than fair for the additional value provided by your solution. I will be building a battery pack next spring and I plan on purchasing your kits. One question though: if I order (40) 8p NESE modules and a...

Thank you for positive feedback. Appreciate it.
One thing i always strongly recommend is garolite gasket ring on positive end of the cell. The pvc is to thin it takes little effort to cut through.

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

@agnesium, I have an interesting question about your modules. Since they don't see to use any kind of spring component, doesn't that mean that if there's a big bump in the road, or that the battery pack drops, the kinetic energy of the drop will have to go somewhere, and will perhaps collapse the p...

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

SLA eould be fantastic if not the material price and the mess. I have a customer who is creator of muve3d. Tje thing with sla is that it might be possible to print in other orientation with a footprint of 22x74. This would allow to fit a lot of modules on a smallest machines. Sla most of the time ha...

only allows to crank up to 67v.
How low could you set the output voltage minimum ? (with both mods pot and programmer ?)

OK. Done firmware patch. Now my upper voltage is capping at 75V and the lowest i can go is 43.4V

Some 9V out, bummer

Can you check your resistor value?

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

The idea is good but in practice is very awkward. When you play with 20um differnces setting up 4 nozzles to be at the same height is very difficult. Also on that setup you have very large mass moving. Stopping that mass causes ringing. You can see it in the video even when he goes that slow. I am l...

Ha. I can tell you its not working in slicer :D on the base, lips are missing. They are to thin for such large nozzle.
