Re: Battery jungle, Lipo, 18650 or 21700 help please.

your solution depends on too many different materials to keep their factory properties wich simply is too much of a variable in batteries where you dont want them. its also restrictive in form factor and power density in comparison by using simple honycomb cell holders and spot welding and the cost...

Re: Battery jungle, Lipo, 18650 or 21700 help please.

trust, me if there is a cost effective non-welding solution that can deliver the same reliablitty and power density i am all over it. sadly there is none. Wander what you mean cost effective? Building with mine will cost less than buying, say Grin pre-made packs but then you need to assemble it you...

Most of the boards have an unpopulated K1 plug that does exactly what you want.
Thanks a lot mate.

Its a bus bar so different to a wire. By the calculator i have it can handle 78A to 60C. V drop 0.034V. As mentioned you can double up or use thicker DIY bus bar

Re: N.E.S.E. the no solder module 20% OFF WINTER SALE

I get the cell current limitation .... But isn't the series connection/joint have its own limits from design/material stand point? The way you are describing is that the only limit is the cell rating itself?? You can always double or tripple up series connections. The path is short and conductor is...

Re: N.E.S.E. the no solder module 20% OFF WINTER SALE

I don't see a series connect Amp rating on the website. Somewhere I read that it's 50A per P module ... but it didn't say how many P configuration?? You can draw max rating of the cell from NESE. If the cell is 20A max you can draw 160A from 8P or 60A from 3P module. You can double that by parallel...

I was wandering if solar could be used to charge through controller and if so what would be the brackets for voltage so its at peak efficiency?
What extra circuitry would be needed?

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

Thank you. I always strongly advise on using brand new cells from reputable supplier. Pressure design relies on good contact and having cleaned second hand cells does not give you that fully. Its a risk where least you could loose is your property and worst, yours or your families life. The link you...

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

If you get decent quality, you should not need anything. I print them at 0 infill. You need 4 perimeters 5 bottom layers and 6 top layers. You need to check an option to fill thin gaps. It depends on slicer how its called. If cell is popping out, print 20x20x20mm test cube and see if your printer pr...

I finally got to read this and I would like to order.

You do not 3-d print yourself. otherDoc Edit: Just read where you got your printer. This means I ...

My machines are Ender 3, but they do not qualify as they are heavily modded. People at skateboard forums print with ender. What problems do you have?

All prices are on the website. There are other relevant components that you might want or not. I do not sell enclosures as it is too custom of a part to have stock.

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

Couple possible reasons for them braking off easy:
Printing too cold
Damp filament
Also, that part of base is weak alone. When you insert tabs and cells, tab suports it from inside. It basically acts like spacer, and all forces are bared by the lid.
