Afaik NESE is the only high preformance non solder battery pack in the market. I do agree that it is a good design and he has put in a lot of effort to ensure it’s safety. Not to say that it’s full of flaws, but there are a few things I would like to improve on:
Cost
It’s kind of expensive. €103.35 for a 10s4p module to ship to the US
Size
it got that extended part for screws terminals. I don’t see it as a necessity. It adds length to the whole P group and IMO length is pretty important since most battery packs are made laying the 18650s along the length of the deck
With that in mind changing these are my design principle:
Low Cost
Easily mass produced and distributed
Compact
See picture below. This is a prototype 12s4p pack with:
design can be any #p single, double stack. honestly this is so easy to make with a 3d printer. the only profit i can foresee is sourcing and producing in bulk.
can you put up more pictures. maybe edit the first post for better overview. where do you connect the modules and where would you put the balance wires from the bms?
So these are able to safely draw roughly about equal amount of amps as a nese module seeing as you’re using the same copper/hardware? not sure how much of a difference in measurements the tabs are between the two. I recall nese doing about 200a or something like that
